A point-to-point topology (P2P) consists of a dedicated long-range, high-capacity wireless link between two sites. Switched point-to-point topologies are the basic model of conventional telephony. Typically, the main or central site hosts the base station (BS), and the remote site hosts the subscriber station (SS), as seen in the figure below.
The BS controls the communications and security parameters for establishing the link with the SS. The P2P topology is used for high-bandwidth wireless backhaul services at a maximum operating range of approximately 48 km (30 miles) using LOS or NLOS signal propagation.
