A 2 Way Radio is a standard digital radio that has been designed to enhance the communication performance even in the country area. It can transmit and receive the voice, content and other ancillary services at a same time without changing the radio frequency. A 2 way radio often provides instant communication in the remote areas which are prone to a network coverage problem. It offers cost-effective communication and gives awesome communication performance at work or on the job site. Many wireless radios including DMR radio and PMR radio also offer the same function. It is also available in a handheld configuration like walkie talkies or Tetra radio.

The Digital Two Way Radios offer superb audio performance by using Forward Error Correction (FEC) and Cyclic Redundancy Check (CRC) coders. These coders detect and automatically correct the transmission errors. A two way transceiver in a police radio plays a very major role. It can be easily carried by the police personnel and allows them to communicate instantly in time of emergency situations like road accidents, riots, etc. Because it is also among the most famous Trunking Systems, they are widely used by railway transportation staff for train radios and also in the Defence Service.

The 2 Way Radio batteries are highly durable that last for a longer time. These radios are portable, easy to carry and can be comfortably clipped in clothing. With the use of Narrowband Codecs Technology, it offers crystal clear sound quality even in the noisy background. PMR radio and Covert radio are made up of premium quality raw materials that are shock, water, and dust resistance. They are ideal when used within workplaces to communicate with the multiple parties that are located at a far distance. Because of outstanding features and wide applications a 2 Way Radio is truly worthwhile to use.

In the wide range of two way radios, Covert radio is very popular. It is being used by the police and other armed forces. It is useful to police officers to get in touch with the other team mates patrolling in other areas. They can stay connected with the police head quarters.

The latest X1e Covert radio is very popular. This power packed radio is the smallest available in the DMR range of radios. One must not get carried away with its elegance and small size. This model is quite tough and known for its utility. The police force finds its blue tooth function advantageous. They use this application to send messages and images. It can be used at ease because it is IP67 protected. It comes with exclusive headphones and a microphone that stays hidden beneath the shirt collar. The additional accessories include a hand control and a supple aerial. The radio has a high durability.

The radio has a wide range. It can identify the voice of the chosen person. It is indeed a matter of wonder that this small tool can identify the voice of the user and the person needing help. The other variety is the licence free radio.

A Licence free radio works on a common eight channel shared with others using the same wavelength. Your conversation can be overheard by other PMR 446S model or it can disturb your conversation. This is the only disadvantage that the radio has. These radios are inexpensive and need no licence to operate. It has a maximum range of 3 Km and is mainly used for entertainment. These Licence free radios are normally what the young children use, when they are out playing and need to be linked with people at home.

Electromagnetic waves of radio since 1870s have created a revolution in the field of communication and IT. Immediately after its invention, radio became one of the most powerful modes of communication of its time. Although, at present we use radio may be only for listening songs or for the entertaining programs it offers, with the passage of time, some people have recognized many of the benefits the technology of radio has to offer and created different kinds of radios. It can range from license free radio to licensed radios. Electronic gadgets making companies produce different kinds of radios considering its utilities. Some of the kinds of radios are briefly introduced in this article.  

Let me first start with Covert Radio. The name itself suggests its utility. Yes, it’s a hidden radio which can be inbuilt in any of your electronic devices. Some companies even produce it in such a way that it matches with your skin colour and can be inserted in your ear. Then there is this 2 way radio. Using this kind of radio one can communicate with other radios having similar frequency. So here, the transmission is both ways. Even in this kind of radios, there are digital two way radios and analogue radios. Digital radios are the advance ones as they facilitate transmission of texts also.

And then there is PMR radio i.e. Private Mobile Radio that is license free radio for private and commercial use available in majority of the countries of the world.

Walkie talkies are the handheld tools popularly known as two way radios also. This system functions on the principle of half duplex, wherein messages can be sent and received one at a time. Users have to press the button present in walkie talkie to send the message and have to release it to receive the message. Their functionality is not bound to any time duration or size duration. Users can send longer messages also. Walkie talkies are mostly used in malls, defence offices, commercials and also for personal use in large distances.

If we recall the old days, our parents use to make trunk calls. You must have wondered ample of times thinking about the meaning. Trunk calls follow Trunking systems wherein from single frequency, multiple connections can operate. This enables easy and secured sharing of information within the organization. Though there are many modes of communications available in the world due to technological development, the base for these modes remains the signals of the network. There is a huge indoor and outdoor coverage problem in rural or congested areas. Repeaters amplify the existing signals from the nearby base transceiver system and provide fair coverage and voice quality.

Continuous growth have evolved the production of DMR Radio (Digital mobile radio) providing services of optimum privacy to the confidential conversations and also providing good coverage and voice quality. Terrestrial trunked radio (Tetra) is yet another radio derived from ETSI. It works on two RF’s (radio frequency) and used mainly by government projects, hospitals and commercial offices.

Are you thinking of buying a new 2 way radio? While you are at it decide what to buy. Licensed or a Licence Free Radio. The deciding factors would be the money you want to spend, where you would be using the radio and the safety. This variety of radio does not need any licence. No call charges to pay, no papers to be signed. This would be an ideal choice if you plan to use it within the limits of three Km. the Licence Free Radio has just one drawback. The chances of overhearing your talk or cause disturbance in the alerts. Many variants of a 2 Way Radio is available in the market.

2 Way Radio can be used anywhere and is a much appreciated kit in the market. It is a household name in U.K. The 2 way radio is a great help if you are on a family outing. This radio is worth its price, if you plan to use it to improve your business. Moreover, the radio can be used for free.

Walkie Talkies are yet another worthy investment. In the earlier days Walkie Talkies were seen at the construction sites, airports and other locations. Besides the cost price of the hand set there is no further expense involved. This makes it popular in every professional sector. An important and improved version of a 2 way radio is the PMR Radio.

PMR Radio is called a professional Mobile radio. One main PMR Radio connects many other mobiles. This feature makes it an important investment in the growth of an enterprise. Transport services still use this radio as a link between customers and the drivers. PMR Radio is a popular choice of the police force. Today the PMR radios offer a lot of service to the clients.

Trunking system means a method to bring about a sharing of limited radio frequencies among a large group of users at the same time. Since the radio frequencies have to be shared, the radio needs a path or track to convey the messages. A main controlling radio organizes a group of people to use a selected frequency. The system works with many groups at a given time. Instead of allotting a radio frequency to an individual, the trunking system gets a user group to share a frequency. In order to enhance the clarity of voice and to get a good coverage the system uses repeaters.

The repeater receives the transmission through a frequency (A) and redirects the received transmission through another frequency. (B) There are two types of repeaters. Wired and wireless. Wireless repeater is a tool to enhance the frequencies sent through various routes. The wireless repeater creates a point for the sound wave to be sent back to main path in a magnified strength. Thus one can say that a wireless repeater gives the main route an added support. Here the thought of portable radio comes to one’s mind.

A Portable digital Radio is an improvised version of a portable radio. This changes the radio frequencies into a numeric version. These radios are useful to person, when he is on the move. Business groups use the portable digital radio to communicate with the staffs who are working at different locations. Another mobile radio that is useful in the business world I is the DMR.

DMR (Digital Mobile Radio) is a procedure of using the numeric code to modify the diction and to send it as frequencies. DMR is an improved version of a PMR solution.

Radio systems have come a long way, from its inception as a simple radio working from a fixed position, for entertainment. It has travelled a long way to be a configured two way digital radio. Digital two way radios have been useful in the communication industry in many ways.

PD782 is a popular hand set, right from the time it was launched. This excellent product is reputed to be very useful at time of urgency. The surveillance department, business men and many other diversified professionals are using this product. Every user has a very good opinion of the PD782.

Another product that attracted people is the X1e covert radio. Amongst all DMR radio it is the smallest, yet very powerful. The instrument has a sleek outlook, but is quite sturdy and has a good multipurpose utility. It also has a Bluetooth facility which makes it useful for the police force. The other industry that uses this DMR radio is the catering or hotel services. People in this profession need to keep their hands free to serve a customer. They find this DMR variant very effective.

The electricity used to work this radio is less because of the amplifier, which is kept off while communicating with others. This Bluetooth enabled radio is equally popular in the United States as is in many parts of Europe.

Along with their own success, many companies try to spread a word to popularize the 2 way radio systems. One supplier who can and is well equipped to give the best, is HyteraUK.

Various communication handsets are available today to entertain and to remain in contact with group. PMR radio is used to contact people. Such mobile radios use two radio frequencies, one to receive and one to send message. These mobile radios us two wavelengths one to receive the message and one to send it, these are used by the groups to stay in tuned to the group while working on sites and the team mates are working in different spots. These adios are also used by many business houses to increase their work.

There are other portable radios that are used to communicate, but these are used at work places where their own personal safety is at stake. For example, people working at the oil rigs and other sensitive area. They need radio sets that are safe to use, the radio sets used by such personnel are known as the safe radio.

Digital radios use a technique of converting the sound into the number pattern and are deigned to perform better. Some of these radios are known simply as pure digital radio.

The digital radios are modified to perform better and the application is very simple to use. One has to choose the location from the alphabets or names displayed. Rest of the work is done by the built in technique.

The wireless radio work on the principle of one main junction with various connections. The range of contact is wide spread, with the option of connecting to other bases, two way radios and also can contact other zones. Thus, this serves as a safety measure to be used by the various pubic service departments. The walkie talkie police radio and such radios are among the variants available. All the three models are used by the police force and security agencies.

Covert radio is a small radio used for security purposes. But of course it can be used for wrong ulterior purposes. It all depends on the user. It would be a welcome step, if it is used to safeguard personal belongings. This piece of radio is to be worn by a person in hidden manner.

The tetra version of covert radio is the latest introduction in the market. The compactness of the model makes it very easy for people to wear it without being spotted by anybody. This is an ideal model that can be used to spot a wrong move in the locality.

Covert radio can be operated from a long distance. This device can identify the voice of the people selected. In case of long session of vigilance use it’s quite a surprise that this tiny instrument can seek the person requiring help and also the people using it.

A radio that can be used to send and get a talking session is called a 2 way radio. A two way radio permits the user to chat with the other radio users on a same radio station. The 2 way radio is available in cell phone, held in a hand or a radio kept on a table. With the television and other electronic goods switched over to the digital technology the two didn’t lag behind and lo! Digital two way radios emerged.

The PMR radio or the professional mobile radio is a version of a two way radio that is used by professionals to enhance their business or career. A licence free radio can mean that licence is not necessary or it is not charged. This radio can be used by anybody who wants to get in touch with family or friends without worrying about the call /roaming charges.

In the past when the mobile phones were not available and it was not within everybody’s means to have landlines with the STD and ISD connections. The Telephone Exchange used to offer the use of trunk calls, to where ever you needed. This was possible with help of the Trunking systems.

Mass safety and security should always be in hands of responsible people. But even they need proper communication and coordination to conduct thins at right time, which is only possible with walkie talkie radios. These types of radios enable police, military and such governments to communicate without any limitation of wire, network or data. These systems are known as PMR radio systems (professional mobile radio systems).

They work on two way communication system and so are also known as two way radio. Such latest radios have trunked and digital message transfer system. The trunked system allows them to communicate to more than one person at a time (i.e. point to multipoint) and also one to one (i.e. point to point). While digital message transfer systems helps them to communicate through legible messages. These types of systems are nothing but open digital platforms for PMR radios and are known as digital radio(DMR).

There may not be a better system of communication than this, which is also capable of breaking network barriers like high-rise buildings, mountains, and such. That is why such wireless radios are given to organizations and systems that are involved in public safety and security like police, frontier guard, ambulance, fire services, etc. A police radio can also be used by private companies for mass or individual security reasons. These radios are easy to operate and are comparatively cheaper than other means of communication. License is required to use such systems and so they are used only for safety and security reasons.

Information and Technology has developed rapidly within last decade and now in 21st century the means of communication has reached a level where there is no barrier to it. Now people are free to use individual network lining and can avoid any bad audio quality or fading problems. There are trunking systems that allow better radio frequencies without any line breakage or fading. These systems are comparatively cheaper to older individual lining system.

The digital radio broadcasting technologies now has developed better systems and networks for 2 way radio giving the DMR radio better options to connect and work. These are 2nd generation radio systems and as they are two way, you can both transmit and receive message. These radio systems are most useful for security agencies for individual and mass protection. Police, fireman, military and such security agencies use these types of radio mobile systems.

These systems can be of different types, depending upon their use they can be mobile, stationary base, and walkie-talkies. To work these types of radio the networking system needs different levels of support and backup. Such supports should be provided without any interruption and for this a direct satellite network connection is also maintained specially in the case of military and high level security systems. In mountain areas the network gets blocked by different blocks and frequency mix and to solve this problem repeaters are used. A repeater takes the message and retransmits it to higher level so that the message goes without any interruption to long distance.

Digital Mobile Radio (DMR) is an upgraded open digital radio system for Professional Mobile Radio (PMR) and to support them the ETSI (European Telecommunications Standard Institute) made Terrestrial Trunked Radio (TETRA) system. It is a two way receiver and is best for mass security purpose, because with this system one can transfer and receive message from point to point and from point to multipoint and vice-versa. These radios can also be operated hands-free and so can be referred as covert radio.

A digital licence free radio is latest addition to two way radio system that gives you charge-free communication facility. This system is used for private use and they work with the help of repeaters and internet. The only drawback of this radio system is that they work only within few kilometres range that too if the area is clear and viable for PMR and DMR frequencies.

Security officials are like the backbone of every, city, state and country. Their need should be given priority, especially when it is for the better of people. For their frequent and interruption free communication they should be given latest wireless radio. These radios should have all the latest facilities that allow it to work even in remote areas or the areas where there is lots of frequency disturbance. These systems for metro communications is capable of working in weirdest frequency interruption and that is why it is necessary that the systems are of best quality with latest networking systems enabled.

In metropolitan areas where there are high-rise buildings it is necessary that the best two way radio India should be used that too with the support of repeater system. The repeater system transmits the frequency at high altitude so that it can reach far distance without any problem or interference.

Taking this system further to another level many companies have started combining MPT trunking. The DMR radio is best useful with this system as the system allows people to communicate in mass along with sending visible messages that analog networking radios were not capable of. Moreover, this system is affordable and is capable of working in tense network areas. This system is very useful for civil security purpose, it is equally useful for private security purpose, but for mass security it is the right thing to adopt.

PMR solution is the latest technology that these companies provide and is best seen with TETRA radio (Terrestrial Trunked Radio) system, because it allows people to communicate in group and also one to one. In India, police radio is also mostly of TETRA system.

Wireless radios mean either a radio that works without the use of wires or it could mean the latest versions of radios that perform using the net connections. There is a misconception about the radio and the wireless being two different commodities. This works on the same principle that a radio officer in the marine mode of transport uses to send messages or the telegraphs work using the Morse code.

In the crucial period of World War II Walkie talkie radios were designed to help the commanding officers communicate with the troop. These instruments later on found a place in the market. It resembles a large sized mobile with an aerial jutting out. The latest version of the instrument is used to control a crowd or where the security group has to communicate within the unit.

A modified version of this is the two way radio, available in both models. This form of radio can send and receive messages at the same time using two wave lengths at the same time, without the transmission tower...  Safe radio, a variant of the two way radio is used by people working in areas like the oil refinery; rig or where the explosives are stocked and has the user’s safety as first priority.

Police radio is specially designed for the police headquarters, to send or receive calls from the squad on the move and address or alert the public. The professionals use this licensed brand to communicate with their teammates at work in different sites.  The English police force was the first to use this model in the late sixties. A variation of this is the Covert Radio or the radio for security and vigilance devised to be worn by the user. This has a microphone to be worn behind shirt collar and transmission kit covered with a leather belt and concealed wires, a bigger version of covert radio is slung to the side of the torso; fastened with straps to the shoulder and the start button is kept in the palm in both cases.

With the changing times and the popular use of the internet has transformed the performance of the radio transmission resulting as digital radio is a product of Pure.

India has second largest population in the world, and with such population the security concern obviously increases. Indian government has already started using PMR Solutions for better communication between the security professionals. Railway, airways, and marine department of India have been using latest PMR metro communications since a decade. But the development never stops, with time threat and terrorism increased. To control the chaos and maintain order and peace Indian security system also has to upgrade from PMR to Digital Mobile radio (DMR).

It is not that the PMR is outdated technology, in fact PMR and MPT trunking system is one of latest and most useful technology. The same technology is used in Digital mobile radio, but because PMR is limited to audio messages and DMR allows audio, video, and other forms of communication with additional facilities, DMR is preferred. The advanced method of trunking is used in TETRA radio. TETRA (Terrestrial Trunked Radio) uses Time Division Multiple Access (TDMA) that allows the transceiver to send and receive message to more than one channel (system) at a time.

Repeaters are installed in places where high rise buildings, mountains or cliffs are available. The repeater receives the message and re-transmits the same on higher altitude so that it can reach far distance without being destroyed or tempered. A marine radio has all these facilities, but there is no end for improvement. The system with TETRA support is also capable of communicating short data services and status message that was not previously possible with analogous system.

These are two way radios and are generally referred as security radios. Development in security is necessary and Indian government should select the best walkie talkie for the security of 121 million people living in India. With the focus on tension and network free system which is quite possible with the help of TETRA and repeaters. There is not much difference between the price of a professional mobile radio (PMR) and digital mobile radio (DMR), so why not choose the best available DMR radio. Motorola, Hytera, vertex Standard, Simoco group, Radiodata, and Tait Communications are among the best international companies that manufacture PMR and DMR devices.
