<p num="1"><br/><br/><br/>A modular wireless repeater typically deployed with a roof-mounted <br/>tower~signal antenna and a base unit with a base unit antenna located within <br/>the building, to which the tower-signal antenna and the base unit are <br/>connected by the user or a satellite TV installer using a 750 coaxial cable. <br/>The system allows a customer to purchase a unit for all wireless service <br/>providers in a given frequency band, such as Cellular, PCS, GSM900, or DCS, <br/>etc., and then add on modules for additional types of service that the <br/>customer may desire in the future. The system also detects and prevents low-<br/>level oscillations. The wireless repeater also performs intelligent power <br/>control allowing it to function properly with near and far base unit antennas <br/>as well as near and far mobile stations.<br/>
