Point-to-multipoint

Point-to-multipoint (PT2MP) telecommunications is most typically (2003) used in wireless Internet and IP Telephony via gigahertz radio frequencies.

PT2MP systems have been designed both as single and bi-directional systems. A central antenna or antenna array broadcasts to several receiving antennae and the system uses a form of Time-domain Multiplexing to allow for the back-channel traffic.
