CELLULAR SIGNAL ENHANCER

A low-cost user portable signal enhancer unit for extending service coverage of wireless communications to a user in a desired area of limited coverage. The enhancement supports an increase of signal power levels to allow wireless communication usage in a location, such as a small office or home office environment where the original cellular signals are weak or unreliable. A base station signal is enhanced by a bi-directional amplifier device (BDA), which receives a base station signal, amplifies the signal power and retransmits the amplified signal in a first signal path to a user in close proximity. The bi- directional amplifier also receives a user signal, amplifies the signal power and retransmits the amplified signal to the base station in a second separate signal path. Dual polarized antennas can receive and transmit the respective signals at opposite polarizations to increase isolation of the signals.

REPEATER APPARATUS

According to this configuration, repeater apparatus causes only f1 to be passed to reach in the distance so as to enlarge cells 207 to 210 according to only specific channel (frequency f1).

REAL TIME ADAPTATION OF A MOBILE REPEATER ANTENNA PATTERN

This document describes a system that is used to dynamically adapt the radiation pattern of the donor antenna of a mobile repeater system. In some implementations, a switched beam antenna is used, in which a location of a mobile repeater is determined relative to a base station, as well as directionality relative to the base station. A correct beam, i.e., a beam with the highest gain based on the location and directionality, is determined and switched on based on a determined gain of that beam.

REPEATERS FOR WIRELESS COMMUNICATION SYSTEMS

A flat-panel repeater includes a housing (50) having a pair of oppositely facing surfaces, at least one antenna element (52, 54) mounted to each of the surfaces for radiating energy in a direction opposite to that of an antenna element mounted to the other of the surfaces, and an electronic circuit mounted within the housing and operatively coupling signals between at least one antenna element on each of the oppositely facing surfaces of the module. Isolation between the antennas on opposite sides of the repeater is improved by various techniques, such as use of adaptive cancellation which removes a significant portion of the feedback signal power, therefore increasing the total system isolation by the same amount. This additional isolation can be used to achieve greater system gain, and therefore significantly extend the range of the system. The repeater may also include a beamforming arrangement for creating a desired antenna pattern of one antenna relative to a base station and a desired ...
