The Digital Two Way Radios has gained lots of popularity in the field of wireless communication systems. Besides its use in a residential area, it is extensively used in the government and industrial sectors. It is ideal when employed in the job sites or workplaces. Generally in the job sites and workplaces, the Two Way Pure Digital Radio (DMR Radio) has very much been helpful for people to communicate with each other located within the work-area. These DMR and PMR radio systems are Trunking Systems, which indubitably plays a major role in the construction sites. However, in the construction sites, the employees often need to communicate with each other to successfully and safely perform the job works or any construction works despite the noisy environment. The Two Way Walkie Talkie is worthy to use in such an environment. It offers crystal clear audio quality by using the Narrowband Codecs technology and thus one can able to hear the clear voice and can safely perform the job works.

The intermittent slowdowns of network are to be expected in many corporate offices or residential areas. There is a plethora of obstacles that can weaken the signal strength and thus cause a network problem. One of the reasons of such a cause is the increasing network traffic. Such a problem can be averted by using Trunking Systems. The Trunking radio system also uses wireless repeaters that come with many towers, and multiple frequencies, which ensures the signal strength and also allows to have conversations between many groups of users.

Thus, the Digital Two Ways Radios including the Covert Radio and Licence Free Radio (aka private radio) have been proved to be useful in various ways to the people working in all sectors including government or private, commercial or non- commercial.

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.

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.

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 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.

DMR is an acronym meaning Digital Mobile Radio. Etymologically, Digital Mobile Radio means a tool to hear radio frequency, quality sound and information in written form. It is a device designed by the institute popularly known as ETSI meaning European Telecommunications Standards Institute. The need of communication is increasing in day to day life for any sector bee it medical, paramedical, defense, politics, education and all. So in this era very useful device named digital mobile radio arose.

It is based on a two slot technology known as TDMA (Time Division Multiple Access). This tool divides the channel to increase the data and voice transfer both. Digital Mobile radio is efficient in terms of Low cost, flexibility, complexity, compatibility, reliability. Many such products are made and catered by a company named Hytera. Hytera.in offers many different models of Digital Mobile Radio while complying with all the ETSI specifications. Furthermore, this kind of product is produced by many suppliers all over the world also complying with ETSI specifications, thereby increasing the supplier’s variety.

The advantages which DMR offers are enhancing the capability to two in the presented channels with the help of time division multiple access technology. It has sustainable battery life with higher power. Also it shows increased voice clarity, quality and data presentation. Further the frequency gets widened when it is compared to analogue signals thus removing the existing limitations.

DMR is a best choice for professionals. It can use data and voice both through the help of two slots provided in the time access multiple division technology thus providing extra benefit in compare to the existing frequency division multiple access which can only go through one channel at a time. Hytera offers six different models for DMR.
