"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.
