Code Division Multiple Access (CDMA) Repeater for Personal Communications Systems (PCS)

"The Personal Communications Systems (PCS) Base-station Transceiver Systems (BTS) area of coverage is physically near (within a few km) of the BTS. It is desirable to provide range extension for the BTS, perhaps to 10 km or more. It is also desirable toquickly deploy range extension of the BTS, thereby filling gaps in mobile communications around the Tactical Operations Center (TOC). A solution is proposed for evaluation, comprised of Hub (or TOC) BTS and Data Link equipment, and remote station data linkand PCS CDMA equipment. The enabling technology is a Hub and Remote Data Link unit developed by Anntron for rapidly deployed data communications networks. At the Hub, a multi-beam antenna, also developed by Anntron for rapidly deployed data links, is theonly means to provide versatile, highly directive links to remote stations. The BTS PCS Converter Unit and Remote PCS Converter Unit may be comprised of commercially available PCS market components. Analysis of existing approaches, repeater designtrade-offs, simulation of coverage, interference to/from the BTS, terrain profiling, data link frequency, software control, laboratory demonstration, and ultimately field demonstrations using existing Anntron outdoor facilities shall be performed todetermine the optimum solution. CDMA PCS provides mobile communications, but only to the extent that the BTS infrastructure is "built out". Total coverage, using a complete BTS, is highly unlikely in
