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.
Walkie Talkies are simple instrument that can be used to transfer messages from one point to another through a fixed radio frequency that is being used by just that instrument. This turns out to be a safer and a faster way for communication and yet is not used as much as it should be used. The reason here can be the unawareness of people related to the use of the DMR radio and other such frequency using instruments. Although these instruments cannot be used as a substitute for any other modes of communication but still they can very well prove to be useful in branches where other modes of communication may not function to well say for e.g. construction sites. For huge construction sites, these can prove to be of great help in connecting and transferring messages from one part of a site to another part.
DMR radio have been introduced to the market as a low cost option to other radio frequencies users who wish to make use of the land mobile frequencies as a mode of communication and yet be safe from issues related to proprietary. Walkie Talkies also functions in the same manner but within a fixed frequency band and can solve problems of communication in areas where the perimeter of work is limited to a fixed small area. As each and every thing that is present in this world, these instruments also have their positives and negatives but if thought and developed properly, these modes of communication can prove to be cheap as well as time saving.
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.
Radios have been featured a lot in the past but off late people have started moving towards more advanced technologies such as the mobile phones and the internet. Even then these radios are being used in the defence and safety departments of various countries. The technological advancements have also been made in the radio technologies and people have started to move from the DMR radio to the TETRA radio which is the latest in the technology as of now. These radios are further advancements of the trunked radio technology that has been used for the emergency services and at airports and metro train stations throughout the world.
Trunked radio offers you with a solution of minimizing the number of lines that would be required if many people would have wanted to connect at the same time. TETRA radio further advances the same technology and offers the following upgrades:
- Lowers the cost of infrastructure which would have been more in case these radios were not used.
- It uses small frequency transmitters and hence the depth of penetration of the signals is greater and hence a larger area is covered in the same amount of signals for which other radios would have required great signal strength.
- Works well in low signal areas wherein other radios would require installation of repeaters. Hence acts as a cost saver.
- Transfers and receives data at a comparatively very fast speed as compared to other normal radios.
- Can receive and transmit encrypted signals at both the user ends.
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.
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.
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.
