* * * * * * If two stations wish to both talk and listen to each other at the same time (full duplex), two separate media have to be employed or a method has to be implemented to share the same media in way that will not cause the TX and RX signals to interfere with each other. In a wireless system this is usually implemented by using two separate channels. Using multiple channels to carry information is referred to as frequency division duplex (FDD). The stations utilizing FDD are usually part of the same communications network and the traffic on the various channels is usually synchronized, often originating from a single station. * * If two stations wish to both talk and listen to each other at the same time (full duplex), two separate media have to be employed or a method has to be implemented to share the same media in way that will not cause the TX and RX signals to interfere with each other.
