Patent number: 8611205Abstract: A two-way wireless repeater and booster system and method are disclosed. The system and method improve signal quality and strength for the middle hop of a three-hop repeater, between User and Network Units operating in the unlicensed bands (ISM and/or UNII), and supporting the cellular (or wireless) network communications channels. The system and method enables the support of a wider repeat spectrum or bandwidth for a given communications bandwidth in the unlicensed band.Type: GrantFiled: December 19, 2011Date of Patent: December 17, 2013Assignee: Nextivity, Inc.Inventor: Behzad B. Mohebbi

Patent number: 8570983Abstract: Systems and methods for full duplex communications on a wireless link between two transceiver devices are disclosed. A first portion of outbound data is transmitted from one transceiver device to the other transceiver device on a first channel, while a first portion of inbound data from the other transceiver device is received on a second channel and the presence of a radiating source other than the inbound data is detected. A second portion of the outbound data is transmitted from the transceiver device to the other transceiver device on the second channel, while a second portion of the inbound data is received from the other of the two transceiver devices on the first channel and the presence of a radiating source other than the inbound data is detected.Type: GrantFiled: May 2, 2007Date of Patent: October 29, 2013Assignee: Nextivity, Inc.Inventor: Behzad Mohebbi

Patent number: 8478191Abstract: Systems, methods and techniques for operating a wireless repeater with multiple antennas are presented. Signals from a wireless communication device are received by a wireless repeater on at least two branch channels associated with at least two repeater receiver antennas. Path or space diversity is resolved from the signals, and the signals are processed on the at least two branch channels to produce at least one strong signal to be repeated to another wireless communication device.Type: GrantFiled: June 2, 2008Date of Patent: July 2, 2013Assignee: Nextivity, Inc.Inventor: Behzad B.

Patent number: 8452231Abstract: A repeater mediates traffic between a network transceiver and a user transceiver in a wireless communication system. The repeater comprises a network unit that maintains a network link with the network transceiver, a user unit that maintains a user link with the user transceiver, a two-way communication pathway between the network unit and the user unit adapted to communicate signals between the network transceiver and the user transceiver in autonomous repeater hops between the network transceiver and the network unit, between the user transceiver and the user unit, and between the network unit and the user unit including downlink transmission from the network unit to the user unit and uplink transmission from the user unit to the network unit, and a detection unit coupled to the network unit and the user unit adapted to detect frame timing of downlink and uplink transmissions respectively by detecting a preamble sequence of downlink and/or uplink transmissions.Type: GrantFiled: February 2, 2007Date of Patent: May 28, 2013Assignee: Nextivity, Inc.Inventor: Behzad Mohebbi

Patent number: 8447230Abstract: A cellular repeater and method of operating a cellular repeater are disclosed. The cellular repeater includes a variable-gain donor antenna adapted to communicate with a base station and a variable-gain server antenna adapted to communicate with a mobile device. A signal from a selected base station selected from one or more available base stations that are available to the cellular repeater is measured at the donor antenna. The gain of the donor antenna is adapted to maximize a signal level of the signal received at the donor antenna from the selected base station. A calibration signal from the server antenna is measured at the donor antenna to determine a radio frequency isolation between the donor antenna and the server antenna. The gain of the server antenna is adapted to maximize the radio frequency isolation between the donor antenna and server antenna.Type: GrantFiled: November 6, 2007Date of Patent: May 21, 2013Assignee: Nextivity, Inc.Inventor: Behzad B.

Patent number: 8351366Abstract: Techniques and systems for mediating traffic between a network transceiver and a user transceiver in a wireless communication system are disclosed. A network link with the network transceiver is maintained using a network unit, and a user link with the user transceiver is maintained using a user unit. One or more replicas of a signal received from the network transceiver on a downlink path or from the user transceiver on an uplink path, respectively, are generated. The one or more replicas of the signal wirelessly are then transmitted on a hop between the network unit and the user unit along with a bi-directional control channel.Type: GrantFiled: October 14, 2008Date of Patent: January 8, 2013Assignee: Nextivity, Inc.Inventors: Behzad B.
