Publication number: 20080013473Abstract: A wireless repeater extends a coverage area of a wireless network base station within a structure or facility. The repeater includes a master unit for wirelessly communicating with the wireless network base station and a slave unit for wirelessly communicating with one or more subscriber terminals. The master unit is connected to the slave unit through new or existing wiring in the structure to enable the master unit to transmit wireless signals to the slave unit on a downlink transport frequency and to receive wireless signals from the slave unit on an uplink transport frequency in a manner that is transparent to the wireless base station and the subscriber terminals.Type: ApplicationFiled: May 18, 2007Publication date: January 17, 2008Applicant: WIDEFI, INC.Inventors: James Proctor, Kenneth Gainey, James Otto, Lawrence Lamont

Publication number: 20070268846Abstract: A method and repeater are described for repeating using a time division duplex (TDD) radio protocol. A signal is transmitted from a first station to a second station using a downlink and an uplink. The signal can be detected on the uplink or the downlink. The repeater can synchronize to time intervals associated with the detected signal that are measured during an observation period. The signal can be retransmitted from the second station to the first station if the signal is detected on the uplink and re-transmitted from the first station to the second station if the signal is detected on the downlink. A gain value associated with the downlink can be used to establish a gain value associated with the uplink.Type: ApplicationFiled: March 30, 2007Publication date: November 22, 2007Applicant: WIDEFI, INC.Inventors: James Proctor, Kenneth Gainey, James Otto

Publication number: 20070025486Abstract: A repeater is configured to selectively generate and transmit control message packets between wireless stations on both a transmit side and a receive side of the repeater. The repeater manages and manipulates an end to end protocol of the control message packets in a manner that does not change media access control (MAC) addresses of the end to end protocol so as to achieve a network objective, such as preventing other transmitters from transmitting while the repeater repeats a signal from its receive side to its transmit side. The control message management is applicable to analog signal repeaters as well as digital repeaters, such as symbol to symbol or packet to packet repeaters, in which physical layer control message management is performed.Type: ApplicationFiled: June 7, 2006Publication date: February 1, 2007Applicant: WIDEFI, INC.Inventors: Kenneth Gainey, James Proctor, Ross Lintleman, Lawrence LaMont, Carlos Puig

Publication number: 20060262026Abstract: An antenna configuration includes two closely spaced antennas each positioned so as to be orthogonally polarized with respect to the other. The antenna configuration increases antenna isolation and reduces electromagnetic coupling between donor side antenna and repeat side antenna. The antennas include printed dipoles connected to respective transceivers through respective baluns to balance the non-symmetrical portions of the antenna feed paths to reduce unwanted radiation therein. Printed features such as chokes and non-symmetrical and non-parallel structures are preferably included in the ground plane of a multi-layer circuit board to reduce or eliminate circulating ground currents.Type: ApplicationFiled: May 18, 2006Publication date: November 23, 2006Applicant: WIDEFI, INC.Inventors: Kenneth Gainey, Christopher Snyder, James Proctor

Publication number: 20050286448Abstract: A repeater (200) facilitates wireless communication between a first communication device (100) and a second communication device (105) in a wireless network using a time division duplex protocol for data transmission. The repeater (200) includes a receiver (310, 315) for receiving a signal on either of at least two bi-directional communication frequencies simultaneously. A signal detector (362) is operatively coupled to the receiver (300, 310, 315) for determining if the signal is present on at least one of the two bi-directional frequencies.
