A point-to-multipoint topology (PMP) is composed of a central base station (BS) supporting multiple subscriber stations (SS), providing network access from one location to many. It is commonly used for last-mile broadband access, private enterprise connectivity to remote offices, and long-range wireless backhaul services for multiple sites. PMP networks can operate using LOS signal propagation or NLOS signal propagation. Each PMP BS has a typical operating range of 8 km (5 miles). File:PMP.jpg
