As we all know communication is the solution for every problem, we must know about one of the easiest and reliable source known as 2 Way Radio. As the name suggests, in two way radios, the communication happens two ways. In this type of radio, we can send and receive messages both alternatively. This sending and receiving can only happen when both the sender and receiver are operational under same channel frequency. There are many types of two way radios which exist in this world. These can be of the following types:
- Half duplex
Mobile phones are also one type of two way radio systems, the only difference being both sending and receiving can happen simultaneously. To work, a mobile phone requires a base transceiver system to receive the signal and relocate the signal to different users. These walike talkies are used by many militants, entrepreneurs, and civilians who all reside in the rural areas where network is a major issue.
With the world moving towards digitization, let’s talk about digital two way radios. Digital two way radios use binary system to send and receive messages. They are the upgraded technology which provides superior voice clarity and simultaneous sending receiving option. Though in comparison to the previous analogue radios, they are complex in functionality. They can be used with many newly available applications (software related) and can also reduce the usage of bandwidth. Individuals have to be cautious while using the ignitable and sodden locations. These can cause modulations in the voice quality and can even hinder the communication in far off places. These issues pertaining to poor network in far off places can be resolved using PMR radio (Professional mobile radios).
PMRs basically transfer small data and voice related messages in rural areas where the network is the concerned issue. It is used for both personal and commercial use within a limited short range of distance. Depending upon the requirement, you can choose from the available range of PMR radio and DMR radio. Like for commercial, large distance, and data safety purpose, one should go for Trunking systems with repeaters. Whereas license free radio is used for short distances and compared to others these are economical in price.
Licence free radio is yet another very interesting type of radio, which has potentially replaced the large sized safety radios. They are very small in size and are equipped with small and…
