WIRELESS REPEATER IMPLEMENTING LOW-LEVEL OSCILLATION DETECTION AND PROTECTION FOR A DUPLEX COMMUNICATION SYSTEM

摘要

A modular wireless repeater typically deployed with a roof-mounted tower­signal antenna and a base unit with a base unit antenna located within the building, to which the tower-signal antenna and the base unit are connected by the user or a satellite TV installer using a 750 coaxial cable. The system allows a customer to purchase a unit for all wireless service providers in a given frequency band, such as Cellular, PCS, GSM900, or DCS, etc., and then add on modules for additional types of service that the customer may desire in the future. The system also detects and prevents low-level oscillations. The wireless repeater also performs intelligent power control allowing it to function properly with near and far base unit antennas as well as near and far mobile stations.
