Talk While Travelling With a Walkie Talkie


Globalization of the world has led to a new search of a vast and an expanding means of communication that can join the world through a single string of communication. Internet acts as one such means of communications. But in search of this single medium for communication, one important factor that becomes very important is the local communication. For local events and emergencies we cannot rely on the internet or other such sources. For these we require fast and swift messaging services such as the walkie talkies which most of the emergency fighting departments such as the police, fire or ambulances have. These radios make use of 2 way radio systems to transmit messages to different radios on a fixed frequency that is allotted to it.

Walkie talkies gives a better proficiency when you are mobile or going somewhere. Most of the police departments of the world make use of these radios to get updates on any criminal activity or calamity or emergencies that may have arose in the nearby areas. The other type of radio is the stationery radios which again make use of the radio systems for transmission of messages but they are stationery at one place such as the police control room. These are available in various features so one can obtain the radio that fits their preferences. Various technological advances in the field of communication have made these radios obsolete but still they are considered to be the safest and the fastest means of communication by the world and hence it retains its place for fighting emergencies.

Covert Radio – A Small and Easy To Hide Radio

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.

Using a Two Way Radio

All of us wish to connect with our loved ones on mobile or the internet or through wired telephones but these types of communications are altogether different than what is required in the field. Modern ways of communication cannot be used in all fields of work as there is a chance of breach of safety and security while transmission and receiving of signals through packets. Hence a safer and an easier mode of communication is the two way radio. A 2 way radio works two ways on the same frequency. A simple walkie-talkie or such instrument is used to establish a connection between two persons or between a radio station and a worker. The radio sends a signal through one frequency and again receives it back on the same frequency.

2 Way Radio
Once you are sending a message on a two way radio, you cannot receive a message on the same radio as it uses the same frequency to do both the tasks. Hence, in a 2 way radio you either send or receive a message.
  • The first step you do is pushing a button and saying your message, the radio transmits your message in the form of packets and the receiver receives it on their instrument.
  • Next, the receiver pushes the button of his instrument and says his message and you receive the message on your instrument.
The radio works the following way and helps in receiving and sending messages faster and easier than any other mode of communication and in places where other communications can prove to be costly.

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.

Range of Communication Handsets Available Today

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 covert 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 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 Modified, Fast Communication Portables Keep Communication Gaps at Bay

Technology advanced to make things workable using batteries, the stationary radio was improved to entertain as well as to communicate. Later on walkie talkie came into existence.

The commercial version of the hand held radio is used by the builders, transport service or in any wide spread site of any large business houses. When the PMR solution could not justify, DMR radio took over.

An exclusive portable radio used by the police force to remain connected to the head quarters as well as the force working in the field is police radio. Whether it improved the working of the police force or not is another issue.
 Another variety is the two way radio. It has the ability to send and obtain messages. The handset permits the user to talk with others, who function from the same band.   To match the changing trend the audio transceiver got modified to digital two way radio.

The communicating mode used by men at sea, by both, the navy and commercial ships are the marine radio. Yet another form of the digital radio is the airport radio, used by the airport staff to contact the control room and the staff working in various sections of the airport.

To get equipped with modern technology and advanced communication trends India too started using the latest two way radio India.

Repeaters are used instead of more radios to increase the range of the radio systems. The efficient working of the telecommunications depends on the paths and connections used by the trunking system. A modification that follows the MPT specifications is MPT trunking.

Metro Communications would be the ideal location to look for all your needs to stay tuned with others.

The Walkie Talkie, Its Variants and Their Uses

The best and most economic alternative to mobile or cell phone is walkie Talkie. It is because, neither one has to worry about getting connectivity with a tower, nor has to pay the exorbitant charges while using it outside the registered state.

A walkie talkie is a safety measure that is useful when one has to be connected with people within a scope, depending upon the walikie talkie’s capacity. This piece, which is so handy that it can be carried anywhere, can help people be in touch with persons they wish to contact, irrespective of their whereabouts. The walkie talkie is a safety measure, or can be useful to a group working in different locations and have to communicate with others in the team. This 2 way radio is available in many varieties like “FRS/ GMRS, GPS“.


The limits of the area covered by the walkie talkie could be from two to ten miles depending on the model and the height of the aerials used. The handset works better in open areas where the where there are no obstructions. Another variety is a portable radio. This is a small sized radio set working on a ‘transistor circuit.’ This variety of radio is mainly used as an audio entertainer.

In place of using a lot of radios and other connecters, it is better to use a repeater to extend the reception range to a wider area. The reception may increase to multiple of hundreds of miles. These may be used to send various types of alerts. Moreover the use of repeaters costs less than the other network alternatives. These attachments may be used in areas that may create hurdles in sending the alerts.

The repeaters are available in wired or without wire types. An application of this kit may be seen as a network of computers to share the information or the net. In a Hub, one can find a lot of connections using repeaters and computer network.

The other types of walkie talkies are the police radio, which is used by the police force. These handsets are used by a police officer to connect with the others in the department and to maintain peace. The other variant of the radio is the marine radio, which is used by the radio officers in a ship. This is found with the commercial ship mates or the naval officer’s. Both use it to send alerts to the other ships at sail or the ground office for instructions.

The Current Scenario of the Uses of Trunking System and Two Way Radios

In the latest methods of interacting with people, the trunking system makes available a set of connections, in various wavelengths, instead of providing individual connection to each person. A specimen of this can be seen in the telecommunications or the ‘VHF’ radios that the security force uses. This technique can be used in computer network.

Trunking system also means the links of buttons and routes in the telecommunication department. A maximum output is gained using few connections. It is also used by the government to support the fire extinguishing department, police and other security departments with the 2 way contacting system, if a same frequency or wave band is shared.

An improvisation of this can be noticed in the use of trunked radio. A two way radio method is used by a large group of individuals instead of using a personal set.  Whenever a group member wants to chat with another person from the group, an unused channel is located and used to converse with the others. The main unit controls and helps the working of the other radios in the system. The chief aim of the system is the proficiency of service a classic example of this is the Tetra Radio.

Terrestrial Trunked radio popularly known as Tetra Radio is a specialized 2 way radio with a walkie talkie gradation. Tetra was mainly created for the exclusive use of the ‘government ‘organizations, armed force and the railways and al the SOS teams. The radio works on TDMA using 4 radio routes. Tetra is designed to justify the European standards.

The main purpose of the DMR is to be cost effective, to be able to connect with all types of types of radios. The specifications are mainly to help the buyers with a range of radio solutions. This model is useful at construction sites where the other forms of mobile communications fail to offer the expected services.

The two way radio is a radio that can offer both functions of sending or getting alerts. The 2 way radio is also called a walkie talkie. The instrument can be used within a coverage area of 2-5 miles. Mobile phones are apt instances that fit the definition of a two way radio because it uses two wave lengths to send and get the talk exchange.

Are Walkie Talkie Radios Really Helpful for Mass Safety and Security?

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 wireless 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 2 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 / safe radio / covert 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.

Development of Digital Two Way Radios


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 digital two way radios giving the PMR 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.

India Needs Tension Free and Latest Walkie Talkie Systems

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 trunked radio 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 two way radio India 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 digital radio India. Motorola, Hytera, vertex Standard, Simoco group, Radiodata, and Tait Communications are among the best international companies that manufacture PMR and DMR devices.

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.
