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.

RepeatersThe 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.

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 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.

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 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.
