Where’s The Best Place To Get a Two Way Radio?

If you’€™re planning a family outing where you’€™ll camp for several days, or if you’re headed for an amusement packed backpacking expedition with friends, you might want to know where to buy 2 way radio communication systems. These gadgets are very small in size, and you can go with them wherever you want to as most of them weigh less than half a pound and you can hardly feel burdened by them as you hike.

Additionally, they come in very handy in regions where cell phones cannot dare venture. Some top quality walkie talkies can provide a huge array of features such as weather alerts as well as SOS signals. 2 way radio online has all kinds of two-way radios including the newest types that come with better-quality frequency options as well as radio ranges.

Types of two-way radios

Bearing in mind that there’s a myriad of two-way radio systems available in the market, arguably the most important question to ask yourself if you want to buy a walkie talkie is: what’s the best choice? However, this isn’t a very hard decision once you understand where and how you’ll use it. Firstly, you’ll need to pick either of the two main kinds of two-way radios, which are family or consumer walkie talkies and professional business walkie talkies.

Within both kinds, you would also want to decide whether a radio system with licensed or unlicensed band is most suitable for you. On the one hand, licensed radios come with powerful 5W frequency transmissions and a wider coverage range. However, you’ll have to be contented with a frequency fee. On the other hand, unlicensed band walkie talkies attract no fees, but they’re comparatively low in power plus a limited range that’s only suitable for casual users.

You would also want to decide between an analogue and a digital walkie talkie. Some businesses search for radio systems that can operate suitably in risky highly explosive environments. Radios with ATEX certification are highly recommended in such areas. You can find all these kinds of walkie talkies and more at 2wayradionline.co.uk

VHF or UHF walkie talkies?

An important consideration when looking to buy walkie talkie is keeping in mind that Ultra High Frequency (UHF) radios will be your best purchase in most cases. Essentially, a UHF radio can never send or receive communication to a Very High Frequency (VHF) radio. As such, if you have some walkie talkies and you’re only looking to add some more units to be used with what you already have, go for the same band.

VHF radios can provide more coverage with less power, but they only function well when there’s little interference between the sender and the receiver. UHF walkie talkies function best with most users since they have shorter waves and can penetrate or get around areas of interference such as hilly areas, thickly wooded areas, in buildings as well as in urban outdoor settings. If you’ll use your radios strictly indoors or if it’s a combination of indoors and outdoors, then UHF is the best choice. You can choose from some of the best VHF and UHF two-way radios at 2wayradionline.co.uk


Scientists Astounded as Four Legged Fossil Snake Turns up In Museum

A unique species of early cretaceous snake – unique in that it apparently had four functioning limbs – has been discovered in the Bürgermeister Müller Museum in Solnhofen, Germany this month.

The discovery was made by Dr. David Martill of the University of Portsmouth, who was showing a group of students through the museum’s collection when he noticed the specimen’s remarkable attributes.

The snake, which measured about 15 centimetres from nose to tail, is thought to have been a carnivore (a fact borne out by the bones of smaller animals preserved in its stomach) and probably hunted via constriction, like many of today’s snakes. Experts believe that it may even have used its limbs to aid in the process.

Built for burrowing (an activity which likely would not have included its limbs in any significant way), this new discovery lends credence to the scientists who argue for snake evolution occurring on land, as opposed to in the sea.

Fossil snakes with stunted hind limbs are known to palaeontologists – and even today’s boas and pythons have a small pair of spurs where their hind limbs are thought to have once been. However, no snake, extinct or extant, has ever been discovered with four limbs.

Appropriately enough, Dr. Martill named the creature Tetrapodophis, meaning ‘four-legged snake’.

However, some experts are not convinced. In our vibrant, ecologically diverse world, there are a great many species of legless lizards that are not true snakes. European slow worms, for example, are snake-like in aspect, but they are lizards, not snakes. Another example would be the Mexican Bipedidae family, which are serpentine in appearance, but which retain a pair of fully functioning forelimbs.

“Is it even a snake? I honestly don’t think so,” said the University of Alberta’s Dr. Michael Caldwell, an expert in snake evolution, to National Geographic.com’s Ed Yong. According to Caldwell and a growing number of other critics, Tetrapodophis lacks certain distinctive features in the spine and the skull that would label it a snake. The fact that this is the only known specimen in the world and that the skull is only partially preserved will probably see the debate continue until such time as a complete specimen is unearthed.

But Dr. Martill is insistent that his discovery is a snake. Speaking to National Geographic, he pointed out the specimen’s backwards-pointing teeth, single row of belly scales, the connections between the vertebrae and the shortness of the animal’s tail after the hip – all of which suggest snake to the educated observer. Of course, many legless lizards also feature these traits, but none has all of them. This means that even if the animal has been mis-identified, it is still totally unique to science.

Even more mysterious are the origins of the fossil itself, which contains the rather distinctive characteristics indicative of the Crato formation in Brazil. Discounting for a second that this is quite possibly the earliest fossil snake known to have emerged from South America, question marks have been raised regarding how the specimen could have made it to Germany when the trade of such artefacts is illegal under Brazilian law.

Since 1942, it has been illegal for any unlicensed person to dig for fossils in Brazil without first gaining permission from the Brazilian National Department of Mineral Production (DNPM). Last year, a number of people were prosecuted (where they faced a maximum sentence of 20 years in prison) for the illegal export of Brazilian fossils to museums in Germany and Great Britain. Odds are that Brazilian authorities, as well as the scientific community in general, will be looking into the origins of such an important find with great interest.


Farewell, Faithful Steed: Veteran Actor (and Sometime Fashion Icon) Patrick Macnee Dies, Aged 93

Patrick Macnee, the actor best known for his work on TVs The Avengers has passed away. He was 93 years old.

Macnee was born in London, England in 1922. His father trained racehorses and was noted for his keen fashion sense, whilst his mother was a niece of the Earl of Huntingdon (which may even have made Patrick a descendent of Robin Hood!). However, such privileged beginnings proved to be only deceptively comfortable for the young Macnee, who saw his father drink and gamble away the family fortune, before leaving the country for India, while Macnee lived with his mother and her Lesbian lover Uncle Evelyn Spottswood. The pair attempted to dress the young boy up as a girl, but settled for a kilt instead, which was how Macnee was dressed every day until he was eleven years old.

Spottswood paid for Macnees schooling, which included boarding school from the age of five, a preparatory school (where he acted alongside a young Christopher Lee in a production of Shakespeares Henry V) and ultimately a spell at Eton, where he joined the schools dramatic society. Eventually however, Macnee was quietly expelled from the school after he instigated a gambling ring and was then caught selling erotic photography and whiskey to his fellow pupils.

By this time though, he had already been bitten by the acting bug and so decided to pursue a career in the performing arts.

Before he could make his West End debut, the young actor was called up for National Service. It was 1942 and World War 2 was in full swing. He began his military career in the Navy as an ordinary seaman, before progressing to sub-lieutenant. Fortunately, a nasty bout of bronchitis caused Macnee to miss the D-Day landings, where the ship he was serving aboard was destroyed and the entire crew killed. He was ashamed of not being present at the battle for the rest of his life. Macnee was demobilized in 1946 with the final rank of lieutenant.

Patrick Macnee learned his craft via a number of small roles, appearing in The Life and Death of colonel Blimp in 1943 and portraying a Spear Carrier in Lawrence Oliviers 1948 production of Hamlet (alongside an uncredited Christopher Lee), amongst other assorted roles. However, as the years passed and his big break failed to arrive, Macnee became depressed and frustrated by his lack of progress.

Eventually, he decided to leave the United Kingdom for Canada, making the difficult decision to leave his wife and two children behind in the process. He arrived in Toronto with just £10 in his pocket. In Canada, Macnees eccentric Englishness made him a genuine novelty and his career began to pick up somewhat. He explored producing and, as an actor, appeared in over 30 televised plays, before finally hearing about a new television series in development called The Avengers.

In The Avengers, Macnee played the unflappable British secret agent John Steed from 1961 to 1969, before reprising the role for 1976 – 77s The New Avengers. Both the series and the character would become an iconic part of British popular culture, creating a legacy that endures to this day. The show made Macnee an international star and proved to be his finest hour as an actor.

The character of John Steed first appeared in The Avengers pilot episode Hot Snow (1961). Here, he was depicted as being an assistant to Dr. David Keel. When Ian Hendry, who had played Dr. Keel, quit the show later that year, Steed became the central character and was partnered with a series of crime fighting accomplices, namely Dr. Martin King (Jon Rollason), Venus Smith (Julie Stevens) and finally Cathy Gale (played by future Bond girl Honor Blackman).

As the series progressed, Macnee extensively re-designed Steeds wardrobe, furnishing his character with the now iconic look of bowler hat, Saville Row suit and gentlemans umbrella. Of course, these garments came to be tricked out with various spy gadgets as the series went on.

It was Steeds debonair, quintessentially British wardrobe that helped the show to become so successful both at home and overseas. In fact, the clothes were so iconic that in France The Avengers is known as Chapeau Melon et Bottes de Cuir – Bowler Hat and Leather Boots.

Macnee also decided early on that Steed should never carry a gun. In later interviews he stated that he was sick of firearms after experiencing “a war in which Id seen most of my friends blown to pieces”.

Besides, a pimped-out brolly is waaaaay cooler.

In 1965, Steed was paired with his most iconic partner (and best, but Im biased since she was my childhood crush) Mrs. Emma Peel. Portrayed by Diana Rigg, Mrs. Peel (designed to have man appeal – hence the name) was smart, self-assured and supremely confident. In a unique twist, Peel often acted as Steeds muscle, being by far the more physical of the two characters. Although he frequently rescued her from harm, their relationship was truly a partnership of equals, making Mrs. Peel, secret agent, martial artist and chemistry genius, a genuine pioneer among female heroines. Macnee was always proud of the strong, positive female characters that were so prominently featured in The Avengers.

Rigg left the series in 1968 and promptly followed her predecessor into the James Bond franchise, while Macnee was partnered with Linda Thorsons Tara King until the series demise a year later in 1969.

ITV revived the Avengers concept in 1976 and Macnee starred alongside Joanna Lumley (Purdy) and Gareth Hunt (Gambit). The show ran for two series, but, despite a positive reception, was scrapped in 1977 due to financial problems.

Away from The Avengers, Macnee appeared in the James Bond film A View to a Kill (1985) and the classic Rock n Roll mocumentary This Is Spinal Tap (1984), where he portrayed Sir Dennis Eton-Hogg, the somewhat sanctimonious president of Taps record company. He also played Dr. George Waggner in 1981s cult favourite The Howling.

In 1998, Hollywood made a disastrous attempt to revive The Avengers. The movie starred Ralph Fiennes, Uma Thurman and Sean Connery and Patrick leant his support in the form of a voice cameo. However, without the twinkle, wit and class of the original John Steed, the idea was doomed to failure.

Finding himself in the enviable position of being a pop culture icon, Macnee was asked to appear in music videos for The Pretenders and Oasis amongst others. He also contributed vocals to a novelty single Kinky Boots with Honor Blackman that was issued three times, the first in 1964, the second in 1983 and the third in 1990, where it eventually became a top 3 hit.

As a television actor, Macnee appeared in such memorable shows as The Twilight Zone, Rawhide, Colombo, Frasier, Battlestar Galactica, Murder, She Wrote, The Love Boat, Magnum P.I, Diagnosis Murder, The Littlest Hobo, Alfred Hitchcock Presents and many others. He even played Dr. Watson alongside Christopher Lees Sherlock Holmes.

In later life, Macnee became a nudist. After an infancy spent in a dress, a childhood in a kilt and an adulthood in the finest suits money can buy, why not spend an old age in the nip? For a style icon that brought the suave and stylish John Steed to life with effortless grace, charm and virility, one supposes that it must have felt like the next logical step.

R.I.P Patrick, you will be sorely missed.


Innovative radio solution protects and preserves Chinese forests

We all know how important radio communications are, and Motorola Solutions have captured a massive coup by providing the radios for protecting the Chinese forests, a feather in the cap for Motorola because Hytera, their biggest competitor at the moment, originating from china, interesting! We found this article on this website.

Motorola Solutions (NYSE:MSI) with its channel partner Beijing Dyne Rcomm Technology are helping to keep China’s Hunan forestry region safe with a MOTOTRBO digital radio system that increases safety and security for employees while helping them to work more efficiently.

China’s Hunan province is rich in flora and fauna resources that are essential to the region’s economy. However, these vast areas which make up around 60 percent of the province’s total surface area can be risky places to work for forest rangers. Forest workers depend on reliable communications to be aware of potential bushfire risks and other emergencies.

The innovative radio system integrates MOTOTRBO digital two-way radios and repeaters, a dispatch console for centralised control and monitoring of the network at all times and Motorola Solutions’ IP Site Connect digital solution to extend radio network coverage over the internet throughout the counties and cities.

“Rangers depend on access to clear and reliable communications. They need to stay constantly connected to their colleagues working in control rooms who have visibility of the entire operation and can help to keep them safe at all times,” said Michael Jiang, China President and Country Manager, Motorola Solutions.

“It’s absolutely essential for forest rangers to know where their co-workers and resources are at all times, especially in times of emergency.

“Hunan’s new radio network provides extensive coverage throughout the region, enabling rangers working across a wide geographic area to report the very first signs of fire so that resources can be deployed quickly and effectively to protect lives and natural resources,” Mr Jiang said.

Hunan’s integrated system connects the surrounding cities and counties through clear voice communications enhanced with noise cancelling features that perform reliably in the nosiest environments. This system also supports data transfer across the radio network, using GPS to pinpoint the location of nearby team members and resources in emergency situations, while text messages and automatic alerts can be sent between the province’s central control room and radio users in the field.

Motorola Solutions has now deployed more than 5,000 radios to major forestry projects across greater China at locations including the Inner Mongolia, Hebei, Liaoning, Sichuan and Guangdong provinces.


The Best Styles of Bluetooth Earpieces

Bluetooth technology has been designed for many different purposes and situations. Consequently, when people want to buy a bluetooth ear piece for a specific situation, there are some things that they will need to consider. Specifically, based on their specific situation and circumstances, they will need to review the best style of bluetooth earpiece that is available on the market today. Since there are different styles that have been made for for one or more reasons, it’s important for each individual to do their research to see which style can accommodate their needs. It is also important to note that the kind the person purchases must be comfortable so that they can wear them for an extended period of time and they fit the devices that they will be used for. Listed below are three of the bluetooth styles that’s currently offered by manufactures all over the United States and abroad.

Bluetooth ear pieces for Mobile Phones

Most people take their mobile phones wherever they go. To work, school, church, parties and all kinds of other events that they may attend. Because these phones have become commonplace in many environments, people have a need to handle them and talk to others when their hands are free. This is also a great reason for individuals who work in certain settings to make sure that they are buying the right style that will best fit their needs.

One specific style that some people may choose is the ear cradle style of headphone. In fact, this kind of bluetooth earpiece is idea for people who want to spend their time working out and performing all kinds of other extracurricular activities. People are also encouraged to buy this kind of style because they may be driving when they receive a telephone call from a family member. Or, they may be working at the job typing a memo or walking around taking care of wide hosts of other kinds of activities that are not conducive to holding a mobile phone by hand to the ear. Whatever the situation, this style of bluetooth earpiece technology is great for many different situations and purposes.

Bluetooth ear pieces and Headsets for Music Lovers

In addition to the cradle style for mobile phones, people should also review other styles as well. One specific style that is also functional in many different settings is the DJ over the head headphones. This style has been designed for the serious music lovers, especially those who can appreciate making distinctions in sounds and beats that come from specific musical instruments like the bass, violin, trumpet and other popular instruments. For those who like and prefer this kind, they will also find that this is one of the best styles for keeping out outside noises that normally interfere with a person’s overall entertainment experience. Also, because they are wireless, they are great for people who like to stay mobile during the day instead of remaining in a sedentary position.

Bluetooth Ear Pieces for IPODs

In some situations, people may want to use bluetooth technology with their IPODs. Therefore, they should consider buying an additional popular style bluetooth earpiece technology. This style is known to be very popular, specifically because it is similar to an actual earbud. An ear bud is also another excellent choice for people who want to remain both active and hassle free. Though this is a great choice for people who like to remain mobile in a wide variety of different situations, one of its main draw backs is that they tend to fall out of the individuals ear. Which means, they can also be lost since it lacks additional support to keep them stabilized inside the ear.


US Presidential Candidate Mocks Disabled Reporter

All-American nutter Donald Trump is back in the news again, this time for making fun of the disabled.

The would-be American President jerked his arms around and acted confused in order to mock disabled journalist Serge Kovaleski, who suffers from arthrogryposis, a congenital joint condition that severely affects his limbs, particularly in his right arm and hand.

One might argue that Trump was just doing an impersonation of an idiot (something he does very well) as a way of slighting Kovaleski’s reporting. From there, one could surmise that the whole thing has been blown out of proportion by an overly sensitive media, until one realizes that Mr. Kovaleski reported on Trump between 1987 and 1993 and that the pair have actually met face to face on numerous occasions.

So, why this latest outburst? Trump was once again using a mis-read article to back up a completely fabricated claim. In this reporter’s opinion, he really should try reading some of these articles ALL THE WAY THROUGH, RIGHT TO THE END, especially if he plans to continue quoting them in public.

Anyway, here’s the story. In 2001, during the aftermath of the September 11th attacks on the World Trade Centre, then-Washington Post journalist Serge Kovaleski reported that Jersey City Police had “detained and questioned a number of people who were allegedly seen celebrating the attacks and holding tailgate-style parties on rooftops while they watched the devastation on the other side of the river”.

Apparently Trump was the only spectator to the “thousands” of Arab-Americans that he claims to have seen celebrating as the twin towers fell. There are no reports anywhere in the media that this rally (or anything even remotely matching Trump’s vivid descriptions) actually happened. Even the mayor of Jersey City has come forward to refute Trump’s bizarre claims, calling them “plain wrong”. Amazingly, Trump himself appears to have waited for 14 years before going public with this shocking sight that only he bore witness to.

BZZZD! Whoops, there goes my bullsh!t detector again!

Mr. Kovaleski’s current employers, The New York Times, have called his actions “outrageous” and, in retaliation, Mr. Trump has taken the fight to Twitter, calling the publication “dumb” and criticising their “poor” management, amongst other things.

Yeah, that’ll show em! How dare they stand behind a disabled employee who has been publicly victimised!

This new outburst was just the latest in a long line of such statements from what appears to be a very public mid-life crisis which has been offensive, painful, embarrassing and laugh-out-loud funny to watch, usually at the same time.

And you thought George Bush was a douchebag!


Can Radio Headset Cause Me To Go Deaf?

According to MRC Institute of Hearing and Research, one in every 6 grownups has sufficient hearing loss to cause problem in social situations. According to the World Health Organization, loud music is the single biggest cause of preventable hearing problems. So you have to assume that the pounding bass delivered right in the sensitive part of your inner year is not a wise idea. Can it. Keep on reading to answer the question “can headphones make you deaf?”

Dr. Foy a Doctor of Osteopathic Medicine says that listening to music through headphones at a very high volume for a long period of time may lead to lifelong loss of hearing for kids and teens. He adds that even mild hearing loss as a result to loud noise may lead to developmental delays language and speech.

The DOs or Doctors of Osteopathic Medicine, look beyond just symptoms to understand perfectly well how environmental and lifestyle factors can affect your well being. They will listen and partner with you to assist you to prevent injury and encourage the natural tendency of your body toward self –learning.

So, how loud is too loud?

Today, majority of MP3 players are able to produce up to 120 decibels of sound, equal to the sound level at a rock concert. At this level, you can lose hearing after only about one and quarter hours.

Dr. Foy stresses to parents and patients that if you are unable to hear anything going on around you while listening to music on headphones, the decibel level is very high. He advises that headphones users should not go beyond 60% of maximum volume while listening to music through headphones .

Lay it loud

It is obviously not damaging to listen to music through your headphones at half the volume of your player. It all depends on how loud the volume is and how long your headphones are on your ears. The world health organization has laid down guidelines as to what decibels are acceptable. Majority of companies manufacturing music players adhere to these guidelines. However constant exposure is still a major problem. It is very dangerous to crank up the volume for a long period of time and may lead to partial deafness. The higher your volume gets the lesser amount of time your ear can take it.

Uncomfortably numb

Unlike individuals who lose hearing during a bomb blast or hearing that sonic boom of an airplane, loss of hearing caused by headphones creeps on your ear and if not contained, its effects can be dangerous. There are people who do not show any signs of deafness during their childhood and hardly hear anything when they are in their sixties. Studies have shown that this is very common for individuals who listen to loud music through the headphones or attend a lot of clubs or live concerts. Deafness brought about as a result of listening to loud music through headphones doesn’t happen overnight. Your ear will warn you before things get really bad with tinnitus.

Conclusion

The question “can headphones make you deaf?” depends on several factors. Duration and level of volume plays a key role. If you limit the duration of time you listen to music through the headphones and also keep the volume low and soft, you will not experience problems with hearing. On the contrary, listening to loud music for a very long time through the ear phones will no doubt impair your hearing ability or worse still make you deaf. The best thing is to adhere to the guidelines laid down by the World Health Organization.


Hytera Connectors are so unclear, which one do you need?

Split by a middle screw, the Hytera PD700 series is capable of connecting all Hytera radios from the same series. This includes the PD715, the PD755, the PD705, the PD785 and the PD795 radios. All of these radios bring something different to the table, in addition to Hyteras trademark solutions. These include an ergonomic design and generally good battery life. The PD715 is probably the most reliable of the bunch. It works really well even in a hazardous environment. It also meets all the ATEX and IEC standards.

The PD755 comes with an increased battery life and a partial keypad, as well as voice call capabilities. Compared to the PD755, the PD705 is a slightly less sophisticated design but it comes with a GPS and supports both analog and digital radios. The PD785 meets all DMR standards and has probably the most ergonomic design out of these models. The PD795 comes with all ETSI and DMR standards.

The Hytera PD500 series connects its radios with a 2 pin connector. The dimensions of the two pins are 3.5mm and 2.5mm. There is a securing screw at the back. This connector can link any combination of the Hytera PD500 series radios together. When I say any, I mean the two radios in that series, since the PD500 series only has two designs, the PD505 and the PD565. The PD505 is very light and somewhat surprisingly, it still has excellent range. Its compact housing results in an improved sound quality. Compared to the PD505, the PD565 has more functions and supports both analogue and digital radios.

PD400 and PD600 series

PD400 and PD600 series radios are connected with a 13 pin connector (which connects to another plastic adapter). This particular connector connects to devices both from the PD400 and PD600 series. The list includes the PD605, PD665, PD685, X1P, X1E, PD405 and the PD415 radios. The PD605 comes with a lightweight design and probably one of the best radios of Hytera when it comes to the prize to value ratio. It has a compact housing and like most of the company’€™s designs, supports both analogue and digital radios.

The PD665 is another high quality handheld device. It has a lightweight metal casing and a full keypad. The programmable keys and the LCD display are surely welcomed additions as well. The PD685 brings very similar traits to the table, the lightweight design and the full keypad can all be found in the PD665. The X1P is different, it’€™s a lot thinner and its main advantage that it will work even in very hazardous conditions.

The X1E meets all ETSI and DMR standards and probably the smallest design Hytera has. Those who want an entry level radio for a more than affordable price, will probably have to look at the PD405. This radio can go for about 16 hours in digital mode. The PD415 has an integrated RFID reader and is generally recommended for patrolling personnel. Just like the PD405, it can last up to 16 hours.


ETRI presents a blueprint of the 5G Future

We will see a huge change in the way we access the the internet in the future when 5G is here, at speeds that only big businesses and high level internet companies see at the moment, we will have this to hand on our smart phones and tablets. When 5G is hundreds of times faster than any of the UK’s broadbands, households will be looking to the mobile phone companies to supply their home broadband.

A 5G future is no longer a distant one, but an upcoming reality. High quality videos of more than 10Mbps can be served simultaneously to 100 users even in a train running at up to 500km/h. People can experience data rates that are 100 times faster than currently available technologies.

The Electronics and Telecommunications Research Institute (ETRI) of Korea will hold a “5G technology demonstration” on the 18th December, 2015. It will demonstrate future SNS (social network service) and several 5G core technologies such as “millimeter wave”, “Mobile Hot-spot Network”, “in-band full duplex” and so on.

5G is the next generation wireless technology that would provide even faster data rates, even lower delays, and even more devices connected than 4G. Accordingly, distinct and differentiated applications are expected in 5G.

ETRI’s “future SNS” is a kind of trial service model to apply 5G technologies that provides dynamic user-centric connection to neighboring people, things and spaces. It is characterized by instant content-sharing between users, communication with neighboring things, and Giga-bps(Gbps)-grade video applications in vehicles.

5G core technologies demonstrated by ETRI include the following:

— MHN (Mobile Hot-spot Network) is a mobile backhaul technology that provides high-speed Internet access of Gbps in vehicles at speeds of up to 500 km/h (e.g. KTX in Korea). Almost 100 passengers can watch videos of high quality simultaneously.

— ZING is a near-field communication technology that enables mass data to be transmitted with 3.5 Gbps data rate between neighboring devices within the radius of 10cm.

— Single-RF-Chain compact MIMO technology enables a single antenna to simulate the effect of multiple antenna. It can reduce antenna volume and cancel inter-antenna interference in a multi-antenna system.

— Millimeter wave (mmWave) beam switching technology provides fast switching of radio beams to mobile users, and therefore allows seamless Gbps-grade service in mobile environments.

— Mobile Edge Platform (MEP) is a mobile edge cloud server on vehicles that enables passengers to enjoy customized Gbps-grade content and connects them with neighbors, things and spaces. It provides user-centric services.

— In-band Full Duplex technology can transmit and receive signals simultaneously over the same frequency band. It can increase spectral efficiency by up to two times.

— Small cell SW technology is designed for AP(Access Point)-sized small cell base stations that can reduce communication dead zones and improve data rates per user in a hot-spot area.

“With this demonstration event, we are officially introducing our R&D results on 5G. We will continue to lead the development of 5G technologies. Also, we are trying to develop commercialization technologies needed by businesses, and to construct a 5G ecosystem.” said Dr. Hyun Kyu Chung, vice president of ETRI Communication & Internet Lab.

In January, 2016, ETRI will demonstrate Giga internet service and future SNS in a Seoul subway train installed with MHN and ZING kiosks. ETRI will also introduce hand-over technology on a millimeter wave mobile communication system and 5G radio access technology that satisfies 1 millisecond radio latency.

As of 2015, ETRI has about 2,000 employees where about 1,800 of them are researchers.


Can you hear radio broadcasts through your teeth?

Do you mean me specifically? If so, then the answer is ‘no’ I’m afraid. I must also say that given the state of pop music these days, I’m actually very glad of it!

So…Awkward question time: are you hearing radio broadcasts through your teeth mate?

Lol. Just kidding.

Whilst it sounds like utter nonsense, there have actually been quite a few reported cases of people ‘picking up’ radio broadcasts through their fillings/dental caps over the years.

Our oft-quoted friend Cecil Adams, of The Straight Dope.com, actually answered this question back in 1992. In his answer, Adams highlighted two particularly interesting case studies. I’ll reprint them here, along with a link to the site in question.

Case #1. George, of suburban Chicago, lost a front tooth at the age of 12. A year or so later, in about 1961, he was fitted with a cap that was attached to the tooth stump with what George recalls as a brass wire. Thereafter he began hearing music in his head, generally popular tunes of the day, usually while he was outdoors. The music was soft but distinct. He never heard an announcer’s voice or commercials and was unable to identify what radio station, if any, he was hearing. After a year or two of this a new dentist put in a cap without a wire and the tunes stopped.

Case #2. Lois, also of suburban Chicago, says it happened just once, in 1947, while she was riding a train from her home in Cleveland to college in Rhode Island at about age 18. The experience lasted maybe 10 minutes. She couldn’t tell what station she was listening to but recalls hearing commercials and an announcer’s voice. She has silver tooth fillings but doesn’t recall if she’d had one put in just before the event.

Actress Lucille Ball even claimed to have helped the allies by intercepting radio signals in this, frankly rather bizarre, way. This story is widely re-told and was even used as part of the plot of the musical ‘Something For The Boys’.

Adams goes on to mention a piece on Snopes.com about the incident, which appears to feature the testimony of the actress herself, who says,

“One night I came into the valley over Coldwater Canyon, and I heard music. I reached down to turn the radio off, and it wasn’t on. The music kept getting louder and louder and then I realized it was coming from my mouth. My mouth was humming and thumping with the drumbeat and I thought I was losing my mind”

According to the Snopes account, after she related this strange story to Buster Keaton, he told her that it had happened to a friend of his.

If you’re interested, here’s Lucille’s account of ‘catching’ the Japanese spies, which allegedly transpired about a week later.

“All of a sudden, my mouth started jumping. It wasn’t music this time, it was Morse code. It started softly and then DE-DE-DE-DE DE-DE-DE-DE! As soon as it started fading, I stopped the car and then started backing up until it was coming in at full strength. DE-DE-DE-DE DE-DE-DE-DE! I tell you, I got the hell out of there real quick. The next day, I told the MGM security office about it, and they called the FBI or something and sure enough, they found an underground Japanese radio station. It was somebody’s gardener, but sure enough, they were spies”

As entertaining as Lucille’s story is, Snopes could find no record of the event, which surely would have been heavily featured in the local, if not the national, news. A cover-up to prevent mass panic? Personally, I don’t think so, as Snopes goes on to mention a Japanese submarine being spotted off the coast of Santa Barbara on February 23rd 1942, which was obviously an extensively covered event.

A discussion on Skeptics Stack Exchange.com uncovers another major flaw in this story (and all others like it). The users suggest (rightly) that any radio signal must first be demodulated in order to make any sense at all. As far as I know, dental fillings have no demodulation circuits.

So, is it possible or not?

Probably not. A demodulation circuit is not and has never been a part of a dental filling’s mix-up.

There is some compelling ‘evidence’ out there, as well as a couple of cases that have been looked into somewhat scientifically and featured in various respected journals, but then again, according to certain statistics, 3.7 million Americans have been abducted by aliens. That alarming statistic, in and of itself, ought to be enough to make you skeptical of anything.


China Have Its Very Own Floating City, Or Has It?

A mixture of panic, fear and awe gripped the residents of the Chinese cities of Jiangxi and Foshan earlier this month, when an ethereal floating city appeared to be hovering amongst the clouds.

It’s the sort of thing you’d usually expect to find in video games, fantasy literature and the deranged ranting of conspiracy nuts (more on them later) – and that’s probably where the rest of the world would have consigned it if the beguiling phenomena hadn’t been captured on video and disseminated to the world via YouTube.

The footage is certainly eerie and doesn’t appear to have been tampered with in any way. In fact, it appears to depict an actual floating city hovering in thin air. Now, there is a perfectly scientific explanation for this unusual sight, but before we get to that, I just had to see what the David Icke crowd were saying about it.

So, after getting my (virtual) jabs, I headed off to YouTube in search of comedy. Here are a few of the best explanations for this event (spelling mistakes and grammatical catastrophes left in deliberately). Enjoy!

First, here’s an observation from a guy who took off his tin foil hat just long enough to share this little nugget with us.

“This is more than just clouds that assume shapes, these are holigraphic pictures, wonder what else they have in store for us, they probably have differant countries developing things in differant areas of technology to make all the tech, miricles start appearing around the world to make us think they are gods, when infact only saten needs technology, The real God allmighty dosnt, he created all and everything!”

…Including Saten and his evil tech? Or am I just being pedantic?

Next up, here’s someone who just went out there one day and never came back:

“I’ve explored about E.T’s and their history on planet Earth , this is true , this is what ancient people called home of the god’s , there are cities in the sky and under the ocean , many of truth is hidden from humans becouse humans like to panic. We are not alone , there are about 100 different alien species on planet Earth , co-existing with us , shapeshifters as well , with more advanced technology than ours”.

…If I were him, I would have explored about the rules of grammar before posting my comment.

Now, here’s an exercise is complete logical disconnect.

“A scientist named AL Bielek, who worked on the Montak Project and the Philadelphia Experiment and other Top Secret Fringe science programs, said that he was taken into the future by ET’s to live in floating cities in the sky around earth, for 2 years. I believed him because I have a close friend who knew him very well and she said that AL was an honest man, before his death in 2011. Or did he die? He maybe there right now in the year 2315”.

Uh huh. I believe in aliens, time travel and floating cities because my mate has a mate who swears it’s true! Your Doctorate is in the mail.

Oh here’s another prize winning pudding brain. Possibly the best of the bunch!

“The point is to make everyone believe there is no God and that aliens exist they’re trying to manipulate you into believe something just like they did with earth it’s flat not round there is Proof about it search it up find it yourselves cause who would believe someone that just says things without showing so please do your research”.

Yes, please do your research before you say crazy, unscientific nonsense such as “the earth is flat!” with a straight face.

Last one now, I promise!!

“It’s actually a breif invasion of parallel universes intervening with our own reality this was proven by scientists and is scientifically possible”

1) No it wasn’t.

2) No it isn’t.

The reality, of course, is far less exciting. The mysterious cloud city is actually an example of a naturally occurring phenomenon known as a Fata Morgana, which is a rarely seen (but very cool) mirage that occurs when a hot atmospheric layer converges with a cool one, creating a temperature gradient that reacts to light. This light then bends, creating the optical illusion that a distant object being witnessed at ground level is higher up than it actually is. This means that the floating city seen in the video clip is actually a projection of the Foshan city skyline itself and was, in reality, nowhere near the clouds.

A quick trip to Google images reveal’s Foshan’s skyline to be very much in keeping with the architectural style of the floating city…

A Fata Morgana is also mooted to be the origin of sailor’s tales about the famous ghost ship The Flying Dutchman. A similar phenomenon, known as a Brocken spectre is thought to be the cause of Scotland’s Big Grey Man of Ben MacDhui as well.

It should be noted that a couple of YouTubers actually pointed this out – and were met with a shower of abuse for their troubles, including one user who typed, without a trace of irony “LOOKS LIKE A F*CKING CLOUD TO ME” and another who responded with “Ya, what you say is bullsh*t. The reflection has to look like what it was reflected from dumbass”. Which it does, so, in the immortal words of Captain Kirk, “double dumbass on you!”

Another user, rather more patiently, explained that “the media want you to believe its some bullsh*t scientific thing”. Damn media, wanting me to believe in science…

Well, I guess that settles it then. It’s obviously aliens. Or magic. Or magic aliens. FFS.


Do You Know What The Term Two Way Radio Mean?

Basically, the name two-way radio means that the radio in question can both transmit and receive signals. The two-way part of the name refers to the sending and receiving of said messages.

Some radios, such as the AM or FM radio you might listen to in your car, can only receive incoming signals, whilst other radios can only transmit signals. A two-way radio, however, can both intercept incoming messages and relay outgoing messages, because of this; two-way radios are a type of transceiver.

At its most basic, a two-way radio is a device that receives radio waves through the air and transmits a return signal.

How it does this is actually rather ingenious. Let’s say a user receives a message on her radio. The antenna on the top of the radio houses a group of electrons, these electrons will respond to messages received on specific channels (different groups of electrons respond to different channels). The electrons will then translate the radio waves into electrical impulses, which are then fed to a small processor. The processor, in turn, converts the electrical impulses into a signal, which the radio’s speakers can then play aloud.

The process is reversed if our hypothetical user is replying to her message, in this instance, the vibrations that constitute her voice will rattle a small membrane inside the microphone. These vibrations are fed into the processor, which converts them into an electrical signal. The electrical signal is pushed out to the electrons in the antenna and the signal is broadcast to our other user.

So you see, the process is clearly working on a two-way basis, hence the name. Two radios, when set to the same channel, should never have any problem connecting with one another (even if they are manufactured by different brands). The communication is pretty much instant, which is a big reason why radios play such an integral part in many areas of our lives, such as travel, security, commerce, public safety and trade.

It is important to note, however, that a radio set to receive VHF (Very High Frequency) signals will be unable to communicate with a radio set to UHF (Ultra High Frequency) mode. There is virtually nothing at all that can be done about this.

Of course, the other name used for handheld transceivers in walkie-talkie, but we reckon that one’s pretty self-explanatory…


Why Are There So Many Motorola Connector Types?

Since the 1920’s Motorola has been leading the advancement of radio technology in more ways than one. From the battery eliminator created in 1928 to the world’s first handheld public safety LTE device created in 2012, Motorola truly has been an innovator in the radio world.

There was one of Motorola’s products that stood out and started paving the way for the Motorola brand name. That was their two-way radio systems. In 1978 Motorola introduced the RDX1000. This device was a portable data terminal. With a built-in keyboard and advanced transmitters, The RDX1000 made it possible for a person to share information, like inventory control, wirelessly with a central computer system. It is because of advancements and products like the RDX1000 that Motorola was awarded the National Medal of Technology twice.

Yet, even with being the one of the leading technological companies they still had their issues. For example, the connectors used for their devices, usually, were confusing and weren’t universal like most of our tech is today. Yes, with being in the lead of the industry with innovative products they needed new forms of connectors and pieces that couldn’t exactly be matched by other companies. To be more specific, the connectors to the Motorola earpieces came with their own specific confusions.

Over the course of the years, Motorola devices have had over 50 different types of earpiece connectors. Motorola earpieces are specific to their devices so the pieces chosen had to be precisely specific to the device it was being matched with. You can imagine, with over 50 different types of connectors, finding the correct corresponding puzzle piece that would fit was imperative. The confusion wasn’t just limited to a small portion of the Motorola accessories. Motorola earpieces were different by model of the same device as well. With the earpieces you can’t exactly go by looks either. Most of the earpieces look very similar with very subtle difference.

Even though some had connectors with very similar differences. Differences ranging from appearance and size of the connector to the type of material used in the pin of the connector itself. This confusion also spans over several different years of manufacturing as well. With connectors from earlier years being a small series of pins in lateral form that would only connect to the proper outlet with the proper series of pins. Or like the single pin connector that would only be in a specific size per model, you wouldn’t exactly be able to take a Kenwood connector and confuse it with a Motorola 2-pin connector because on these connectors the pins are of a different size to the Kenwood. Some specific connectors can be understood considering the advancing of the technology as well as the device it connects to has some significance.

The importance of the device does have some control over the type of connector used as well. Because you don’t want to issue and offer a radio and have to worry about it getting lost or stolen and being used for an inappropriate purpose. But, you would expect a device in the same model family to be able to connect or at least the connectors to be somewhat interchangeable. This isn’t the case with Motorola radios. For example, The DP2400 two way radio takes a Clip on block style of connector. While the DP3400 responder radio has to have a Screw in Block  connector in order for the product to be used properly. Even though the station and responder radio are two different products, they share similarities and commonalities. Also you would expect them to share the same connector.

Unfortunately this is the case with many of the Motorola earpieces.


Alonso unfazed by rule changes

Fernando Alonso doesn’t believe the changes to the start procedures that will come into effect at Spa will make much of a difference.

As of this weekend’s Belgium Grand Prix, the FIA will clamp down on radio communication between drivers and the pitwall and only critical information will be relayed. Teams will also be prevented from changing the clutch bite point once the cars leave the garage ahead of the race.

However, two-time World Champion Alonso isn’t expecting any disruption to his usual pre-race strategy.

“It will not be a significant change. I know that there is some talk about this but maybe for next year or the following years will be more different,” the Spaniard said.

“What we will have here is just some restrictions in communications with the drivers and the team etc but I think… at least in our team we were not doing any specific communication or strategy during the formation laps etc so it will not change much.”

There will be more changes next year as the FIA has issued a technical directive that states engineers will not be able to coach the drivers over the radio on things like tyre degradation and fuel saving.

Although the McLaren driver admits drivers will have to “pay a little more attention”, he doesn’t think it be a train smash.

“Well, I don’t think it will make a huge change because… yeah, we are receiving some information now on the radio about tyres, about fuel or other things on the car but we are perfectly aware of what is happening in the car and what is the best solution for the specific issues that we are facing during the race so if that information is not coming, it will come anyway by instinct and by the reactions of the car,” he said.

“So yeah, we will have to pay a little bit more attention to a few things that now we rely a little bit on the radio but it’s not a big change and probably it’s welcome, all those changes, to have a little bit more to do in the car and feeling a little bit more important.”

It’s difficult to see why F1 are strangling the communications between drivers and teams, One team does not gain anything over any other by relaying information over the radio, but as Alonso has said in this article on planetf1.com it’s not an issue.


P.S – This Message Will Self Destruct: New Email App Allows Automatic Encryption

Remember how Inspector Gadget always got given those top-secret messages that would self-destruct upon reading? Well, a new app has been devised that can do just that for your emails.

Confidential CC is a free app, designed for both Android and iOS devices, that allows the user to send self-deleting, automatically encrypting files that can be viewed only once…And never again.

The app also prevents recipients from forwarding or printing the messages in question. In a very real sense, you can read it once and then its gone.

“You receive all your email like usual, we just add a new address line that lets you send a CCC self-destruct email,” said the app’s Co-Founder Warren Barthes, formerly an executive with French Telecom, at the Collision Technology Conference in Las Vegas, Nevada earlier in the year.

Of course, other secure email apps have been attempted before, but none has proven to be 100% safe. Could Confidential CC be the one that finally achieves it?

The app was created by co-founders Warren Barthes, Rachel Triggs and Jeremy Landau and their story (according to the group’s official website, anyway) goes something like this:

“Confidential CC was born when the co-founders realized they had a common need – to send an email without a trace. A short time later they set out for this goal. After working hard to confirm the technology, legal and execution were possible, the CCC team took their idea to the next level by striving to provide not only confidential email, but an updated, smart, and attractive user interface across all systems, catered to our users’ daily lives”.

Compatible with Yahoo!, AOL, Gmail, Hotmail and Outlook, amongst others, the app allows users to access all their email accounts from one place and has been designed to be as user friendly as possible. Confidential CC can also cancel accidentally sent messages and can be instructed to send email messages out at a specific time of day.

It looks good, but the customer reviews have been a mixed bag so far.

iTunes user Alukakum praised the usability and the continuing updates, but a customer named IT User Review panned it, calling the app “clunky at best” and pointing out that users can only synch one email account per provider to the app itself.

Of course, this app is new to the marketplace, so customer reviews are few and far between.

Nevertheless, it goes without saying that, if Confidential CC can deliver on its many promises, then it could become a very profitable enterprise indeed. Co-Founder Rachel Triggs certainly thinks so.

“It’s unacceptable that email, which is free and open for all, is presenting such huge risk to users. Maybe, in five years, people will use CCC lines in Gmail, Outlook, everywhere.” She said at the Collision Conference.

If all goes according to their plans, this could be the first chapter in the story of how a small start-up firm from the US revolutionized email security for all online customers. As with all things, time will tell.
