Connecting Through the Trunking Systems

The working of a Trunking Systems for people who are not aware of the term can be said to functioning the same way as a trunk of a tree that connects all the different branches of a tree to the roots of the tree. It acts as a medium or a bridge between the two. The same way this system works by connecting different tetra radio with a common base station. The science was not invented for the radio industry but has been taken from the telephone technology where trunking was used for STD connections.

Trunking systems helps in: 

• Minimizing the total number of lines required otherwise for any project related to one to many or many to many connections.

• The infrastructure and the raw material required for the same also gets reduced drastically.

• The total number of lines that would have remained idle otherwise will be reduced as trunking system itself finds an empty line for transmission and receiving of messages which otherwise would require one line each for receiving and transmitting messages. Multiply these with the total number of users that would be transmitting and receiving messages at a time and you would know that the lines required for such connections can go as high as a million.

• The trunking systems reduces the hassle of maintaining so many lines and provides a hassle-free solution for establishing the same number of connections with a minimum number of lines.

• The system is a boon for services related to defense and emergency as minimum number of lines to handle makes it easier and swifter to transfer messages.

The Latest Covert Radio is Both Sleek and Useful

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.

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.

Establishing a Mobile Radio Standard with DMR

Radios have been used extensively all throughout the time in different parts of the world for one or the other purpose. The radios have been used for defense purposes, emergency purposes, entertainment purpose, communication purpose and many such purposes. These are called radio as they make use of radio waves for establishing connection between transmitter and the receiver. As of now, the most upcoming field where these radio waves are being used is the DMR or the Digital Mobile Radio. These are considered to be the next big thing in the field of communication. The only drawback of radio waves is that they are prone to signal losses and other attenuation. This problem is likely to be solved by using wireless repeater that can be placed at some distance from the transmitter. 

This wireless repeater receives the signal from the transmitter and re-processes the signal and converts it into a strong signal in the form of a zero phase wavelet pulse. The only problem that might be faced is that a number of such repeaters would be required to cover long distances and at every repeater there is going to be a signal loss. 

DMR has been recognized as an established standard in the field of mobile radios and there are researches going on to improve on the technology so that it can be extended to a global level. 

The only problem that is being faced while trying to go on a global scale is the cost of infrastructure that would increase drastically with the current technologies that are available.

Walkie Talkie – The Best Portable Device for Amazing Voice Quality

In the world of broadcasting, the two way radio has owned lots of fame because of its outstanding features. It is capable of transmitting and receiving the signal at a time, therefore is also known as transceivers. It offers incessant performance despite having acrid environment. It is available in various electronic products like mobile, stationary base, and walkie talkie or handie-talkie. The walkie talkie is handheld portable transceiver. One of the remarkable benefits of using walkie talkie is that it is available for all types of sectors; whether government or private, individual or group, or corporate or social. It plays a very crucial role in the armed forces by offering constant performance even in harsh environment.

The wireless radio often called the portable radio, is easy to carry and has the incredible voice quality even though dropped or operated in the toughest condition and environment.

MPT Trunking is the most popular Trunking system for trunked mobile radio technology. This Trunking system can be easily set up and available at cost effective rates. It allows the user to access the network by sharing a set of frequencies and thus ensures the magnificent sound quality without any disturbance. The MPT Trunking offers great assistance to Professional Mobile Radio (PMR) and thus allows it to provide superior broadcasting networks for users. PMR solution offers ceaseless conversation facility to the users suffering from jamming network problems. The electronic device repeater allows the broadcaster to increase signal strength and thus gives the better voice quality. Wireless repeater offers help by reducing the impact of obstruction that may affect the wireless connection. It is cost effective and easy to connect.

Improve the Country's Security by Using Police Radio

Because of global terrorism, each and every country is strengthening their security structure. For hi-tech security, apart from deploying latest weapons, the better intra communication among the security personnel also plays a very crucial role. Using a police radio, one can have the amazing intra communication quality during the time of emergency incident. It can be easily operable in the control room of the police station and can direct the police personnel to the spot of emergency incident. The safety and security of the airport are the primary aim of country's security agency.

Using the airport radio, one can easily manage the crowd during the peak days or holidays. With use of it, the airport security personnel can get the secret information about criminals from the central security agency and can keep the vigil march throughout the airport.

The marine radio can be used for various purposes. It plays a magnificent role during the time of rescue operation. It allows the marine operator to communicate with the harbours, locks, bridges, and marinas with the outstanding voice quality. The TETRA radio is also a kind of walkie talkie which proved to be operable in and withstand the adverse condition of the environment. It plays the important role in metro communications by offering help in rail and road transportation services, emergency services, fire and safety services, etc. The walkie talkie like a trunked radio has incredible battery durability and offer full network signal even in low network area. It offers high voice quality by using Narrowband codecs technology.

Walkie Talkies – A Compaq and Easiest Means of Sharing Messages

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.

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.

Communicating Below the Sea with Marine Radios

Radios are a very common instrument for each and every one of us around. Different types of radios are known to us such as the old AM radios, the new FM radios but all these are only radios that can receive radio signals either in AM mode or FM mode. A rather deeper and a more serious use of radios are made in emergency services such as the police departments, fire fighters, ambulances, armies etc. All of these use radios and these radios work best on land. Another use of radio made in the defence is by the navy.

 As the navy has to do all its work in or around water, a special radio called Marine radio is used for communication.

This Marine radio makes use of the wireless radio technology for receiving and transferring signals over and below the sea. Since defence is a very important and a secret part of any country, special frequencies are used for receiving and transmitting the messages. Wireless radio transmits the radio frequency through a medium, either air or water, and hence is highly susceptible to signal losses and noises at the receiver end.

Hence, special high frequency waves are used that can penetrate deep into the ocean and avoid signal losses and attenuation. Also since these waves travel through a medium, safety is often a concern and so even after taking all of the care to avoid such unwanted copying of signals, as a safety measure, the messages are sent as codes that need to be deciphered at the receiver end.

Wireless Repeater Is Indeed a Support to the Main Routers in Trunking

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.

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 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 last and most important in this series of radio is the PMR solution. PMR stands for the professional mobile radio or private mobile radio. Wherein, with a central point many mobiles can connect. Hence, even today when far advanced radios are available, these models are used by the cabs associations for quick and easy communication.

The Various Tasks of a Digital Two Way Radio

A radio that is able to send and receive message or that can converse or reply at the same time is called a two way radio. Mobile, fixed or a movable variety is available. The digital two way radio is an improved version of the two way radio. The sound and the clarity of the reception in a digital two way radio is done by a sparkler instead of the usual spiral. Whenever a frequency is received the sparker changes the sound wave to connect to that particular program. This radio gets an indication using a code of numerals. This leads to an improved reception.

A cell phone is the best possible paradigm of a digital two way radio. This structure mainly works on two different sound waves to get and send a conversation effectively and simultaneously. In the beginning, the radio system worked by one station sending out the message while many other stations received. But with the advancement of technology the two ways started performing effectively.

 The two way radio India also worked on the same principle, because each country has its own way of allocating the sound wave lengths. This makes it user-friendly and practical to be used by the staff working on the system. The two way radio in India or anywhere in the world is useful in two ways, as a source of entertainment and information. Although the radio broadcasting in India is still hooked to the Fm Stations, a transformation in the digital radio India is expected in the near future when the Bangalore based ‘Radiowalla’ is launched.

The two ways technology can be seen in the wireless radio, this version of the radio is mainly used by the security forces, to manage the law and order. In some cases the commercial version of these are seen to be used by the construction companies where the work force have to communicate with their team-mates very frequently.

The Radio systems are normally the radio broadcasting stations that every nation has. They not only help spread the audio form of entertainment, but also provide the current and the latest news. This system can be used to educate the public in many aspects. The Radio systems used in the airport or the airport radio is chiefly used to help the flight personnel to keep in touch with the control room and give or take information regarding the take off, landing and the weather conditions.

The MPT Trunking helps people use series of two way radios to communicate very effectively. One radio works as a control point while others use this point to connect to the frequency that they want.

The Trunking Systems and the Working of Other Radio Systems for Security and Entertainment

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.

The idea of trunking , in which a main telephone  switch board with many connections that use a same  sound wave length  can use instead of each one being allotted a different personal  link. A miniature form of the trunking system can be seen in offices where a telephone operator and intercom systems are used. 

With the use of the two way radio handset, called walkie talkie, nobody can complain about the communication amongst the working team or other group members. But, yes, one has to watch the area coverage by the walkie talkies. The walkie talkies were originally designed for the exclusive use of the police and security force.  Later on the commercial models of the same were sold in the market for the use in many professional fields like construction.

The PMR radios were replaced with an advanced version called DMR radio or the digital mobile radios. The DMR offers talking, information and various other facilities and aspects. The chief motto of the DMR is to offer an easy to handle, minimum price factor and inter usable feature with all the other brands.  

Instead of using many radio sets and other connecters to improve the reception range of the service repeaters are used at intervals to increase the area of reception of conversations, information and other features. Tetra or the terrestrial trunked radio is movable radio working on two frequencies. Tetra was patterned mainly for the use of various departments of the governing bodies and other SOS services. 

An Array of Radios Available for People to Use for Entertainment and Work

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.

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.

DMR Radio or the Digital Mobile Radio is an improved version of the professional mobile radio (PMR). DMR offers audio, video coding and other added services. 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.

Metro Communications offer the best services in supply of the communication service to the residential, commercial complexes and industrial houses. They have all the PMR/DMR models, because the company believes in satisfying every customer. The success of the company lies in their efficient and fast work to satisfy a customer.

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.

Radio Systems That Gives You Extra Security

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 portable 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 2 way radio 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 trunking system. The digital radio India 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, airport radio is also mostly of TETRA system.

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.

Wireless and Its Variants Used by Professionals

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.
