Definition Edit

Point-to-multipoint (abbreviated as P2MP, PTMP, or PMP) communication is a term that is used in the telecommunications field to refer to communication which is accomplished via a specific and distinct type of multipoint connection, providing multiple paths from a single location to multiple locations.

Point-to-multipoint communications is most typically 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.
