Simplex communication is a communication channel that sends information in one direction only. A duplex communication channel requires two simplex channels operating in opposite directions. The ITU definition of simplex is a communications channel that operates in one direction at a time, but that may be reversible; this is termed  half duplex  in other contexts. For example, in TV and radio broadcasting, information flows only from the transmitter site to multiple receivers.
