A 2 way radio differs from a broadcast radio in the sense that it can receive as well as send messages and can be used for communication between two people. These types of radios are available in several different configurations. These include the hand held radios, mobile radios and stationary base radios. These radios can either operate in a full duplex mode or a half duplex mode. In the full duplex mode, these radios can be used for both sending and receiving data at the same time over different channels.
In the half duplex mode, these radios can be used for either sending or receiving data over a single channel. There are various things that one needs to know about the 2 way radios .
