Patent number: 7783318Abstract: A system and method for amplifying cellular signals while maintaining the output power of the amplifier below a prescribed power limit. The network amplifier system may include a variable gain module having an input configured to receive an uplink signal from a handset and configured to apply an amplification factor to the uplink signal to generate an adjusted uplink signal. A detector is used for detecting a level of the uplink signal. A gain control module is configured to control the amplification factor in order to limit the output of the variable gain module to ensure that the level of the adjusted uplink signal does not exceed a predetermined limit. An antenna is coupled to the output of the variable gain module and is configured to transmit the adjusted uplink signal to a base station.Type: GrantFiled: July 13, 2007Date of Patent: August 24, 2010Assignee: Wilson ElectronicsInventors: James W.

Patent number: 7729669Abstract: A system and method for amplifying cellular signals and reducing interference introduced into a cellular network by the network amplifiers. The network amplifier includes an antenna configured to receive a downlink signal from a base station and a variable gain module for amplifying an uplink signal received from a handset. The variable gain module applies an amplification factor to the uplink signal to generate an adjusted uplink signal to be transmitted to the base station via the antenna. A processor is used for determining a value of the amplification factor, where the value of the amplification factor is a function of a level of the downlink signal. The amplification factor may be selected so that interference introduced into a cellular network by the transmission of the adjusted uplink signal is substantially eliminated.Type: GrantFiled: September 26, 2006Date of Patent: June 1, 2010Assignee: Wilson ElectronicsInventors: V.

Patent number: 7486929Abstract: A system and method for optimal adjustment of gain of a network amplifier, and for substantially reducing oscillation produced by a network amplifier. The network amplifier includes first and second antennas for the transmission of signals between a handset and a base station. The signals are amplified by first and second variable gain modules by an amplification factor as determined by a control circuit. The control circuit determines the optimal value of the amplification factors by analyzing the signals. In the event that an oscillation is detected, the control circuit adjusts the amplification factors in a manner that substantially reduces the oscillation.Type: GrantFiled: July 13, 2006Date of Patent: February 3, 2009Assignee: Wilson Electronics, Inc.Inventors: V.

Patent number: 7409186Abstract: A system and method for substantially reducing oscillation produced by a network amplifier. An exemplary method includes receiving a cellular signal at a first antenna of a network amplifier and applying a first amplification factor to the cellular signal. The resultant amplified cellular signal is transmitted to a target destination via a second antenna. A first signal level of the cellular signal is measured while the first amplification factor is being applied to the cellular signal. Then, a second amplification factor that is less than the first amplification factor is applied to the cellular signal, during which a second signal level of the cellular signal is measured. If the second signal level is significantly less than the first signal level, the first amplification factor is reduced by a predetermined amount.Type: GrantFiled: July 13, 2006Date of Patent: August 5, 2008Assignee: Wilson Electronics, Inc.Inventors: V.

Publication number: 20080096483Abstract: A method and system for conserving power consumption within a network amplifier. The system includes a first communication device for receiving a Time Division Multiple Access (TDMA) signal. The TDMA signal includes both broadcasting timeslots and non-broadcasting timeslots. A power amplifier amplifies the TDMA signal to generate an amplified TDMA signal. The TDMA signal is analyzed by a sensing circuit for detecting the presence of the broadcasting timeslots. The sensing circuit turns the power amplifier on during the broadcasting timeslots and off during the non-broadcasting timeslots so that the power amplifier only amplifies the TDMA signal during the broadcasting timeslots and does not amplify the TDMA signal during the non-broadcasting timeslots. The resultant amplified TDMA signal is then transmitted by a second communication device.Type: ApplicationFiled: October 20, 2006Publication date: April 24, 2008Applicant: Wilson ElectronicsInventors: V.

Publication number: 20060209997Abstract: A cellular network amplifier for reducing interference in a surrounding cellular network. The cellular network amplifier includes a communication device for receiving an uplink signal from a handset and a first variable gain module for applying an amplification factor to the uplink signal. The amplified uplink signal is transmitted to a base station by an antenna. The antenna also receives a downlink signal transmitted from the base station enroute to the handset. The downlink signal is analyzed by a control circuit, which determines a value of the amplification factor applied to the uplink and downlink signals based on the level of the downlink signal. The value of the amplification factor is determined such that the signal transmitted from the antenna does not introduce interference into the surrounding cellular network.Type: ApplicationFiled: June 8, 2006Publication date: September 21, 2006Applicant: Wilson ElectronicsInventors: V.
