Who Made the 1st Two Way Radio

The first two way radio made its way into the Western market in 1923. Despite its late appearance, the device was primarily conceptualized in 1907 as part of a military communication program. There has been some controversy regarding who first made the two way radio. However, most people seem to attribute this invention to Frederick William Downie, Senior Constable of the Victorian Police in Australia. In this article, we take a look at the path that this radio has traversed through the ages- from 1907 to the 21st century.

Origin of the 2 Way Radio

In the 1900s of Australia, the 2 way radio was installed in police cars and used as means of communication for the purposes of surveillance, checking locations and keeping team mates posted on updates. This was a breakthrough invention for the police as it caused an instant increase in the overall efficiency of working. From instant reports to integrated surveillance systems, the two way radio was pivotal in improving the effectiveness of the Australian police force. Suddenly, people discovered the ease with which the law of the land could be enforced and security could be maintained. This was the one method by means whereof many lives were saved and the state became one of the safest places in the world. Needless to say, the overwhelming response that the two way radio received propelled it to fame and it then became one of the most popular methods of law enforcement in the world.

The popularity of the 2 way radio rose steadily over the years. From police cars, the device’s many uses branched out and it became a part of navy ships and even military operations. Since many mariners and platoon commanders faced problems of communication, the convenience of the two-way radio was highly appealing to all. Transmissions of messages became convenient and there was a certain smoothness that the radio communication afforded to the operations.

The Creation of the Modern Day 2- Way Radio

The global status that the 2 way radio enjoyed is also one of the biggest reasons for its adaptation into various communicative derivatives including the modern day walkie talkie and even the modern cellular phone. Before it achieved this global, improved status; however; the two way radio was one of the most rudimentary objects that could be used in police surveillance. The first radio was so heavy and cumbersome that it used to take up the entire backseat of the police car. While it might have had many benefits, the sheer size and volume of the object made it difficult to catch and apprehend criminals at the earliest. With technological improvements and the right incentive, the two way radio has improved leaps and bounds. What once used to occupy almost half the car space can now be fitted into a pocket with ease, while fulfilling the same purpose as its predecessor.

Uses and Benefits of the Modern Radio

From the 1900s to the 21st century, the two way radio has made immense progress. What earlier was used exclusively by the police had now become an instrument in the civilian space. From law enforcers to children, almost everyone could purchase walkie talkies and use it. This was the first time that the world saw the walkie talkie as an instrument of recreation. These days, walkie talkies are used as much by kids for their games as they are used by professionals in emergency situations. From medical EMTs to firefighters, walkie talkies have become a regular in the city’s working scenario.

One of the biggest uses of walkie talkies these days are in firefighting operations. Coordinating external help and amassing the required support for the rescue operation are common functions that are carried out over the two way radio system that was once pioneered by Downie. Over and above its use in emergency situation, the two way radio is also used for the basic purposes of communication and organization in construction sites, among municipal workers and in many facets of working companies.

Concluding Thoughts

When one considers the many benefits that the 2 way radio has brought to the world population, one cannot help but pay homage to the genius of Frederick Downie. While the remarkable transformation through the ages is something that we must all bear in mind, it is undeniable that the blueprint was an instance of pure creative and imaginative genius. There are multiple uses of the walkie talkie in the modern world today. From communication in emergency situations to its importance for recreation, the modern two way radio is arguably one of the most important facets of communicative technology. All in all, the genesis and development of the two way radio is undoubtedly one of the most outstanding creations of the previous century.

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.

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.

Motorola Solutions to buy UK’s Airwave for $1.24 billion

As this article shows, Motorola move closer to sealing the deal to supply the emergency services for the whole of the UK, this move seems to prove what we have been saying, as Airwave have a working relationship with the emergency services and a good majority of the equipment they use are Motorolas’ own products they are in an excellent position now.

Walkie-talkie and radio systems maker Motorola Solutions Inc said it would buy UK-based communications company Airwave Solutions Ltd for 817.5 million pounds ($1.24 billion) to beef up its services business.

Shares of Schaumburg, Illinois-based Motorola were up 3.4 percent in extended trading on Thursday.

Airwave, owned by a fund of Australia’s Macquarie Group Ltd, provides voice and data communications to more than 300 emergency and public service agencies in Great Britain.

Motorola’s sales have slipped as its major customers, which include police and fire departments as well as other government agencies, curtail budgets.

The company is trying to strengthen its services business – which provides communication services to governments, businesses and public safety agencies – to drive growth.

Activist investor ValueAct, Motorola’s largest shareholder, said last month the company’s shares were undervalued and that it would talk to its board about ways to enhance shareholder value.

Motorola Solutions said it plans to fund the purchase of Airwave, which has about 600 employees, with bank financing and cash on hand.

The deal is expected to add to adjusted earnings and free cash flow immediately after closing in the first quarter of 2016, Motorola said.

Different Types Of Two Way Radio Antennas

An antenna is essentially the most crucial element of a two way radio and other transmitting application such as cell phones, television, radar, or satellite communication. It is responsible for performing the most important task – converting electric power to transmittable radio waves and the other way round.

How an Antenna Works

To transmit a signal, the transmitter provides an electric charge that oscillates at a specific radio frequency to the terminals of the antenna. Consequently, the antenna sends out corresponding electromagnetic waves. During reception, the antenna takes some of the power of the transmitted electromagnetic waves to generate an extremely small voltage for the terminals, which is then redirected to a receiver that amplifies the signals. This is basically how an antenna works.

Extensive Applications

The applications supported by an antenna go beyond communication. The same concept powers today’s high tech wireless applications that run computer networks; Bluetooth enabled systems, garage door openers, and baby monitors. It’s important to know that a perfectly functioning antenna is not only critical to the functioning of your two way radio; it also helps maintain the life or longevity of your equipment.

The Bigger, The Better

The first and most important rule of thumb about an antenna to keep in mind is that the taller it is, the higher your db gain. A high volume of db gain is critical to achieving a stronger reach and better performance of your two way radio equipment. This basically translates to, “the bigger, the better.” However, in order to achieve results in practical situations, the antenna can have only so much height. In essence you have to sacrifice convenience for performance or vice versa. You can’t walk around or even install a gigantic antenna for all your needs, say for example your car radio.

Positioning of Antenna

The second rule of thumb pertains to the positioning of your antenna. The most optimal position for then antenna would be the centre of your metal car roof. In situations where this is not possible, you would need a “no ground plane” antenna. A no ground plane is basically just a metal surface that goes around the base of your antenna so that you have something for the radiating signal to react with. The next aspect you need to consider for your antenna is the frequencies at which you would be transmitting on. A VHF radio transmits and receives in a range from 136 to 174 MHz.

Chubby and Long Antennas

There are different kinds of two radio antennas available depending on how you want to use it. The large stock antenna is powerful and can be replaced or upgraded as you require. The shorter or stubby antenna provides a great deal of convenience. You can add a longer whip antenna to enhance your range. When it comes to two way radios, you stand to gain a great deal of advantages by having a business radio that comes with a removable antenna. The one problem is that removable antennas may not necessarily be compatible with all kinds of radios.

Lenovo to phase out the Motorola brand name

The Motorola brand, which has been a fixture in the technology world for 85 years, is about to be phased out by its parent company Lenovo.

The US-born company was bought from Google by the Chinese giant in 2014, with the company continuing the lineage of Motorola handsets.

However, the days of the Motorola name appearing on phones and in marketing materials will come to an end this year.

Motorola Chief Operating Officer Rick Osterloh told CNET: “We’ll slowly phase out Motorola and focus on Moto.”

The company plans to simply use ‘Moto’ and the familiar batwing logo for high end devices, while all other handsets will feature the Lenovo Vibe branding. Even the top devices like the Moto X will feature the blue Lenovo logo rather than the Motorola name.

The rather complex blending of the two brands will involve Moto devices being introduced to Lenovo stronghold territories and marketed it as premium devices.

The budget Vibe devices will also be introduced to western markets to complement the high-end Motorola devices according to the report.

If this wasn’t confusing enough, the Motorola company is being retained from an organisational perspective and that division will now oversee all of Lenovo’s smartphones activity.

Motorola is credited with inventing the first mobile phone with the DynaTAC released in 1984. Likewise, the company’s importance to the development of consumer technology in other sectors cannot be overstated.

In 1930 it released one of the first commercially successful car radios and in the 50s had a major role in the foundation of cable television systems. In 1969 a Motorola radio transmitted the first words from the Moon to Earth and in 1990 it launched the world’s first digital HD television.

Adios, Motorola.

Whilst the Motorola Brand name is strong in the mobile phone and two way radio industry it is an important institute in the communications field that should be preserved, as this article says it was there at the start of telecommunications and has been around for longer than most of us can remember, it would be a shame if it was pulled apart by Lonovo.

A Right Cock-Up: Hilarity Ensues As Council Workers Paint Huge Tarmac Penises For Fun & Profit

A residential area in Tamworth, Staffordshire has become the talk of the Internet after council workers painted a bunch of dicks on the tarmac there.

Staffordshire County Council contractors Amey were tasked with the job of re-painting some old road markings in the area and apparently, they decided to get a little bit creative with the task. Using their school desks and the cubicle walls of gents toilets for artistic inspiration, the team apparently painted a dazzling array of gigantic penises all along the tarmac.

Featuring members of many different shapes, sizes and states of apparent arousal, the phallic paintings have angered local residents who, yknow, didnt necessarily want dicks painted on the floor outside their houses.

The official line is that the paint somehow caused a reaction with the existing markings, creating the distinctly adult imagery completely by accident. Uh huh.

Now, is it easier to believe that Staffordshire County Council has access to magic penis paint, or that the workers got a little bored and covered the street in dicks?

Given the amount of the constantly complaining, utterly humourless residents frequently quoted in articles, the street appears to be full of uptight pricks anyway, so its likely that the contractors didnt think anybody would notice a few more.

Since The Penis Incident, the Council has received a bewildering 300 complaints about the “disgusting mess” caused by a bit of magic paint and a few repressed urges. 300? The average fella wouldnt get that many complaints if he took his actual penis out at a gathering of 300 people!

Resident Graham Wood (no joke, thats really his name!) was quoted by Yahoo! News as saying, “There are some very bizarre, obscene shapes. One of them looks like someones giving someone the finger sign”.

Well, if you can create a detailed hand giving someone the finger using road paint, Id say that youre probably some sort of artistic genius. However, my personal favorite is still the extra long, almost mournful penis that appears to be dragging his two big balls across the street in search of food…Theres just an unspoken poetry to it all if you ask me.

Apparently, the paint settled down long before the local residents did and any surviving penises have since been hunted down and eliminated by the contractors.

All joking aside (but not for long, I promise!), whether the phalluses were painted there deliberately or not, this story really serves to highlight what a humorless bunch of dicks the British public can be at times.

Wrestling Star Challenges Presidential Candidate

In the wake of Hulk Hogan’s racist outburst about his daughter dating a black man, another racially charged issue has emerged from the weird and wild world of pro wrestling.

TNA wrestling star Tigre Uno, who has also wrestled for Mexico’s AAA (Asistencia Asesoria y Administracion) promotion as Extreme Tiger (sometimes written as Xtreme Tiger) has issued an open challenge to US Presidential candidate Donald Trump, over statements made by the latter regarding Mexican immigrants in the US.

Trump, himself an inductee to the WWE Hall of Fame and a personal friend of WWE boss Vince McMahon, made a number of ill-conceived public speeches wherein he blamed illegal Mexican immigrants for bringing drugs and crime to the country, before further suggesting that Mexican immigrants were more likely to be rapists than anybody else in the US.

He then promised that, if elected, he would build a great wall along the US/Mexican border. And no, Mr. Trump wasn’t trying to audition for Robert De Niro’s role in Machete either…

In an act of sheer, thoroughbred lunacy, Trump announced his desire to be US President by uttering the following “They’re sending us not the right people,” he said, followed by “The US has become a dumping ground for everyone else’s problems” and also “They’re sending people that have lots of problems and they’re bringing their problems,”

“They’re bringing drugs, they’re bringing crime, they’re rapists, and some I assume are good people but I speak to border guards and they tell us what we are getting.” He went on.

Mr. Trump then declared that the American Dream was dead and that current President Barack Obama had turned the US into a third world country- which is actually quite funny, when one considers that, if his statements were accurate, the opulence in which Mr. Trump actually lives would make him the latter day equivalent of a feudal lord.

In response to this nonsensical tirade, Tigre Uno began to author a series of Tweets challenging Trump’s views. He then delivered a heartfelt interview – in Spanish – to the viewers of TNA’s most recent Impact Wrestling broadcast. The video package featured shots of Tigre in his hometown of Tijuana speaking with local people and spending time with his children.

In a surprisingly cool and patient manner, the masked luchador said “I believe that Mexico is a great country. I have lived my whole life here in Tijuana. Mexicans are just passionate about our people. We are so proud of our history, who we are. We are very hard working people, we love our country. We are so proud of our culture and we love our lifestyle”

When asked to discuss Trump’s claims, Tigre responded, “Mostly all Mexicans who come to America are good people. They are good workers. They are artists, they are plumbers, they are carpenters, they are construction workers – some are even landlords. The people who come to the United States work hard, they come to do good things, come to make a life for themselves and their families”

Then, his point made, Tigre officially challenged Donald Trump to come to the next Impact Wrestling broadcast, saying, “I’m going to show you who a real Mexican is and who the real Mexicans who came here to work are. Not all Mexicans are bad. I’m Tigre Uno and I invite you to come to Impact Wrestling”

Fans have criticized TNA for attempting to capitalize on the furor surrounding Trump’s comments, but the reality is that Tigre originally made his statements without consulting the company and that TNA only became involved once they had ascertained that Tigre was indeed the author of the Tweets.

If Trump does turn up for the taping (which, quite frankly, would be a huge surprise in and of itself), he’s in for a long night. Trained by Rey Misterio Sr (Uncle of former WWE Champion Rey Mysterio), Tigre Uno has a long history not only of brutal, all out ring wars featuring tables, ladders and the like, but also of performing graceful aerial maneuvers that seemingly defy gravity.

Tigre is the current reigning TNA X-Division Champion and has also held AAA’s Cruiserweight and Tag Team Championships, as well as winning the 2011 Rey de Reyes (King of Kings) tournament.

Yes, wrestling may be a scripted show, but that doesn’t mean that Tigre couldn’t do some serious damage to Trump if he got the chance…

Two Way Radio, What Does It Essentially 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…

Important things about Purchasing a Two Way Radio for your Restaurant

Running a restaurant is hard. Personnel in different areas need to communicate well in order to provide the best dining experience for customers. The conventional way people restaurant staff communicate is by shouting or talking loudly at each other. While this can be an effective way to communicate – this method has worked for years – it turns a restaurant into a noisy and chaotic place. Many customers are actually looking to dine in peace. So having all those noises, even if they are meant to provide better service, can actually turn off customers. Restaurant staff can communicate without disturbing the dining experience of customers with the use of walkie-talkies. two way radios for restaurants provide plenty of benefits. The most important ones are discussed below.

A good Investment

Many restaurant owners are having second thoughts about buying walkie-talkies because of the additional investment that it entails. The hesitation is understandable since running a restaurant is expensive as it is without a communication system. But if you are a restaurant owner, you can look at buying a walkie-talkie as a good investment. Having a walkie-talkie for your restaurant can help you serve your customers more efficiently . It can improve customer turnaround time and it can help provide a better dining experience for your patrons. All of these improvement can translate to more profits for your restaurant. So if you are looking for a way to improve your operations and make more money in the process then improving communication system by getting walkie-talkies is a good idea.

Improve Communication

In any organization, good communication is important. A bad communication channel can ruin the good relationship among the staff and between a manager and the people around him. If you own a restaurant, then you probably already know that it is a pressure-packed environment. It doesn’t take much for someone to crack under this kind of pressure. A good communication tool such as walkie-talkie can help ease the pressure. It can avoid miscommunication. If you are a manager, for example, and you noticed that tables are not set yet. Instead of shouting across the room and creating an angry atmosphere in your restaurant, you can simply relay your instruction on the walkie-talkie.

Choosing the right Walkie-Talkie

Of course, not all restaurant walkie-talkies are the same. Some are better than others. Not all walkie-talkies are created equal. When choosing a walkie-talkie, the first thing that you need to consider is performance. The system should be able to provide clear audio that has the ability to break through the noise that is usually present in a restaurant. A bad walkie-talkie can affect your business as adversely as the absence of a walkie-talkie system. Can imagine a restaurant staff trying to decipher the message being relayed by his manager over a walkie-talkie that is sending choppy signal? This kind of scenario can turn into a tragedy very quickly. The next thing that you should look for is comfort. The walkie-talkie should allow freedom of movement for the staff to be able to perform their job well.
