Mobile topology

A mobile topology is similar to a cellular network because multiple base stations (BS) collaborate to provide seamless communications over a distributed network to both subscriber station (SS) and Mobile subscribers (MS). This topology combines the coverage area of each member BS and includes measures to facilitate handoffs of MSs between BS coverage areas, as seen by the car MS in the diagram below. It uses advanced RF signaling technology to support the increased RF complexity required for mobile operations. Each BS coverage area is approximately 8 km (5 miles). Mobile WiMAX operates using NLOS signal propagation on frequencies ranging between 2 and 6 GHz.
