Point-to-multipoint communication

In telecommunications, point-to-multipoint communication is communication which is accomplished via a distinct type of one-to-many connection, providing multiple paths from a single location to multiple locations.

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.
