Point-to-multipoint communication is a term that is used in the telecommunications field which refers to communication which is accomplished via a specific and distinct type of one-to-many connection, providing multiple paths from a single location to multiple locations.[1]
Point-to-multipoint is often abbreviated as P2MP, PTMP, or PMP.
Point-to-multipoint telecommunications is most typically (2003) used in wireless Internet and IP Telephony via gigahertz radio frequencies. P2MP systems have been designed both as single and bi-directional systems. A central antenna or antenna array broadcasts to several receiving antennas and the system uses a form of Time-division Multiplexing to allow for the back-channel traffic.
