Abstract: One embodiment of a system comprises a community WLAN comprising fixed equipment that includes a centralized base transceiver station (CBTS) coupled to a public network and a plurality of remote transceiver stations (RTSs) each coupled to a number of a plurality of UEs, and, via a radio link, to the CBTS. Respective cellular radio frequency signals transmitted by the CBTS to the RTSs and by each RTS to the CBTS are frequency converted from respective first frequencies within conventional cellular frequency bands to respective second frequencies above the conventional cellular frequency bands. The respective frequency-converted cellular radio frequency signals received by the CBTS from the RTSs and by each RTS from the CBTS are frequency converted from respective second frequencies above the conventional cellular frequency bands to respective first frequencies within the conventional cellular frequency bands.

Abstract: A system (100) and method for providing high capacity voice and high speed data communication between user equipment terminals (UEs 104) and a public network (108). Generally, the system (100) includes a community Wireless Local Area Network (WLAN 102) having a centralized base transceiver station (CBTS 114) coupled to a public network (108), and several remote transceiver stations (RTSs 118) each coupled to several UEs (104), and, via a radio link, to the CBTS. In one embodiment, the CBTS (114) and RTSs (118) include a Global Systems for Mobile communication/General Packet Radio Service (GSM/GPRS) transceiver (148, 154) to provide data communication, and a WLAN transceiver (150, 156) to provide voice communication. Preferably, the WLAN transceiver (150, 156) is compatible with an open standard, such as IEEE 802.11.

Abstract: A communication network (100) and method are provided that reduce loses between a base transceiver station (BTS 102) and an antenna (114). Generally, the network (100) includes a tower (112) having a tower-top (110) on which the antenna (114) is supported, a BTS (102) and a separate amplifier (124) on the tower-top near to the antenna, the amplifier in a communication path between the BTS and the antenna. In one embodiment, the network (100) further includes a backhaul (122) on the tower-top (110) near the antenna (114), the backhaul configured to couple signals between the BTS (102) and a base station controller (BSC 108). Preferably, the backhaul (122) is integrated with the BTS (102). In another version, the backhaul (122) is configured to couple communication signals between the BTS (102) and the BSC (108) via a wireless communication system (128).

Abstract: An improved modular masthead for use in cellular communications networks is described. The masthead unit includes a power amplifier, a duplexer and a local power supply that supplies the power amplifier. The power amplifier is arranged to amplify outgoing communication signals received from a base station. In a preferred embodiment, the masthead also includes a low noise amplifier for amplifying incoming communication signals and passing the amplified incoming communication signals to an associated base station. With this arrangement, the masthead forms a modular unit that is distinct from the base station such that the modular masthead may be replaced independently of the base station. With this arrangement the range of a cell within a cellular network may be changed by simply swapping an existing masthead unit with a second masthead unit having a different power supply thereon and making software changes in the system.

Abstract: A noise suppression apparatus for use in a receiver includes an input terminal adapted to receive an inbound signal. A channel splitter is coupled to the input terminal and configured to split the inbound signal into a substantially identical first signal and second signal. A first mixer coupled to the channel splitter and configured to receive the first signal, and a second mixer coupled to the channel splitter and configured to receive the second signal. A first local oscillator is coupled to the first mixer and configured to generate a first LO frequency signal, and a second local oscillator coupled to the second mixer and configured to generate a second LO frequency signal, where the first LO frequency signal and second LO frequency signal differ from one another.
