Abstract:
A repeater for a wireless network in which a signal radiation path provided by building wiring is used to provide spatial separation between at least two radiating points. The repeater is preferably packaged into a housing that is suitable for use as an Alternating Current-to-Direct Current (AC/DC) transformer (or wall wart). If the radiating point includes at least one antenna, the antenna may also be incorporated within the transformer housing. The radiating points can be are provided by at least two antennas, in which case the building wiring includes a coaxial cable, such for carrying video or cable signals. The building wiring may also be standard Alternating Current (AC) three wire conductor cable which may or may not be placed within building walls. In this implementation, the radiating point is determined by a matching circuit. A frequency conversion circuit can cause the radiation from at least one radiating point to occur at a carrier frequency that is different from the carrier frequency of the other radiating point.
Abstract:
A directional antenna is pointed based on a ranking process. The ranking process of choice uses both Es/No and Pilot Power parameters as measured from a pilot signal for best overall system performance in the forward and reverse links. Using this pointing and ranking process enables adaptive pointing of the directional antenna in interference and multi-path driven environments. The pointing and ranking process may be used to select the nullbestnull pointing angle for communicating with a given base station or for selecting the given base station. The process may include fine tuning techniques for use in different environments. The fine tuning may include the use of weights related to the operating environment or directivity of the directional antenna.
Abstract:
A repeater that extends the range of a wireless communication system especially one using Time Division Duplex (TDD) protocols. The device preferably translates signals received on a first radio frequency channel to a second radio frequency channel. The repeater preferably monitors one or more channels for transmissions. When a transmission on one channel is detected, the repeater is configured to translate the received signal to another channel where it is then transmitted. The device thus solves a problem of isolating input and output signal from one another.
