Two Way Radios
Functions of Two Way Radios
Two way radios are not ordinary radios used for entertainment purpose as most of the people have this misconception. These are essential communicating devices, which are used in several embryonic and emergency situations where all other communicating devices and technologies are inadequate and not enough. To provide seamless communication facilities two way radios are the most trusted devices even in this age of advanced mobile communication. Of course all mobile handsets are mostly like two way radios. Although they differ from each other in some areas. But all best two way radios are trans-receiving communicating devices. These two way radios receives and transmits data on two different radio frequency (RF) at the same time. So the communicating medium is not interrupted while receiving and sending voice data.
There are numerous kinds of two way radios based on divergent technologies, functions, systems and classifications. These diverse groups and sub-groups of two way radios have their own models and brands. So you may choose your own best two way radios according to your choice of use and requirements. Based on principles and technologies used we may classify them as Conventional and Trunked. The two way radios based on Trunked type are Motorola Dimetra, EDACS and Logic Trunked Radio etc where as the best two way radios covered under Conventional systems are used for Marine VHF radio, UNICOM, Amateur Radio and Family Radio Service etc.
The best two way radios are equipped with more transmitting radio frequency channels. So the cost of such two way radio communicating device are higher than the traditional simplex technology handsets. Simplex channel system enabled two way radio handsets use a single channel for transmit and receive. This simplex system two way radio frequently use open architectures, which allow any radio meeting basic standards to be well suited with the whole system. Although simplex technology enabled two way radio devices are very reliable but rage of distance covered is too short. So the handset user must be within the range of each other. The available single channel bandwidth limits the number of synchronized conversations. Some of the best two way radios are enable with Duplex channel systems that transmit and receive voice data on different discrete channel frequencies. The duplex types of two way radios are again subdivided into two groups. Half duplex and full duplex handsets. Half duplex system device is consists of Duplex systems can be divided into two types. The term, half-duplex refers to two way radio systems where the user of a push-to-talk switch is required to communicate. Where as in case of full duplex two way radios, it functions on multiple channels.
Before buying any two way radio handset device, always insists on better-branded products that covers multiple channels and longer distance communication. Some of the popular best quality two way radio manufactures are Motorola, NXDN and Kenwood etc. But choosing a best two way radio, you need to analyze which types of service do you need and what should be the range of your planned communication network? Similarly two way radios may also be based on Analog or Digital technology.
