Abstract: A base-station transceiver system (BTS) operative in a cellular telephone network, consisting of a main up-link port and a diversity up-link port whic h are adapted to operate cooperatively to receive up-link signals over-the-air from cellular telephones such that both of the ports receive the up-link signals from each of the cellular telephones. The two ports are coupled to receive signals from wired telephones, such that the main up-link port receives signals only from a first group of the wired telephones and the diversity up-link port receives signals only from a second group of the wire d telephones. The system also includes signal processing circuitry which is adapted to receive the signals from the up-link ports and convey the signals over the network.

Abstract: Disclosed is a telephone system using a telephone network interface configured to couple a cellular telephone to a cable network. The interface coupled in this way enables transmission and reception of communication signals to and from a cellular telephone network over the cable network allowing communication of the cellular phone to a cellular network connected to the cable network, for instance. The telephone network interface is further configured to enable the interface to communicatively couple with the cellular telephone using packet-based communication, such as session interface protocol (SIP) packet based communication.

Abstract: Techniques to determine the position of a terminal under the coverage of a repeater in a wireless communication system. In an aspect, an identification code is transmitted for each repeater and used by the terminal (or a PDE) to unambiguously identify the repeater. The identification codes for the repeaters in the system can be implemented with PN sequences at defined offsets that are specifically reserved for repeater identification. In another aspect, the identification code for each repeater is transmitted using a spread-spectrum signal designed to have minimal impact on the performance of the system and to be recoverable by the terminal in similar manner as for a forward modulated signal. In this way, no additional hardware is required for the terminal to recover the identifier signal. In one specific design, the spread spectrum identifier signal is generated in accordance with and conforms to the IS-95 CDMA standard.

Abstract: A duplex radio transceiver (50), coupled to baseband circuitry (46,48) and to an antenna (32), includes a receive chain (48), a transmit chain (46) and a duplexer (49). The transmit chain (46) includes filter components (52,56) that attenuate signals originating from the transmit chain in a receive frequency band by a stop-band attenuation that is approximately equal to or greater than the stop-band attenuation of the duplexer in the receive band. Similarly, the receive chain (48) includes filter components (68,72) that attenuate signals in a transmit frequency band by a stop-band attenuation that is approximately equal to or greater than the stop-band attenuation of the duplexer in the transmit band. A bias control circuit (74) senses a power level associated with radio signals in the transmit chain and adjusts an amplifier (66) in the receive chain responsive to the power level.

Abstract: A method for wireless communication, including positioning a first plurality of slave transceivers within a region and positioning a second plurality of slave transceivers within the region in positions spatially separated from the positions of the first plurality of slave transceivers. The method further includes receiving at the first plurality and at the second plurality of slave transceivers a reverse radio frequency (RF) signal generated by a mobile transceiver within the region and generating respective first and second slave signals responsive thereto. The method also includes conveying the first and second slave signals separately to a base transceiver station (BTS) external to the region, and processing the first and second slave signals conveyed to the BTS so as to recover information contained in the reverse RF signal generated within the region.
