Patent number: 7522556Abstract: An intelligent gain controller (IGC) for an on-frequency repeater implements a method for identifying a desired narrow band signal within a broadband RF signal. Thus, a candidate narrow band signal within the broadband signal is isolated. The isolated narrow band signal is then processed to detect repeating features of the narrow band signal. The detected repeating features are then analyzed to identify the signal type of the isolated narrow band signal. System gain of the in-frequency repeater can be controlled based on the power level of the identified narrow band signal.Type: GrantFiled: March 3, 2005Date of Patent: April 21, 2009Assignee: Spotwave Wireless Inc.Inventors: Wag Hanna, Colin Kellett, Theodore Pantazopoulos, Mike Roper, Russell Smith, Quilin Yuan, Jie Zhang

Publication number: 20060034351Abstract: In a system for monitoring stability of an on-frequency repeater, a wide-band signature (WBS) signal associated with the repeater is generated, and inserted into an output RF signal transmitted by the repeater. Signal components corresponding to the WBS signal in an input RF signal received by the repeater are detected and analyzed to estimate a feedback path loss L.Type: ApplicationFiled: August 13, 2004Publication date: February 16, 2006Applicant: SPOTWAVE WIRELESS INC.Inventors: Colin Kellett, Mike Roper, Shane Young, Jie Zhang

Publication number: 20050176368Abstract: A distributed adaptive repeater system includes a donor unit, two or more coverage units (CUs), and an intelligent hub. The donor unit operates to maintain bidirectional wireless communication with a base station of a wireless communications network. Each coverage unit maintains bidirectional wireless communication with transceivers located within a respective coverage area, and is further adapted to independently control a signal path gain to ensure stability of a respective feedback loop to the donor unit. Finally, the intelligent hub is operatively coupled between the donor unit and the coverage units, and adapted to monitor a status of each coverage unit.Type: ApplicationFiled: February 25, 2005Publication date: August 11, 2005Applicant: SPOTWAVE WIRELESS INC.Inventors: Shane Young, Mike Roper, Jie Zhang, Steve Allen, Paul Simpson, Colin Kellett

Publication number: 20050118949Abstract: A method of detecting oscillation in an on-frequency repeater having an RF signal path coupled between an input antenna and an output antenna. In accordance with the present invention, a first RF signal power level within the RF signal path is detected during an un-muted period in which transmission of an output RF signal through the output antenna is enabled. A second RF signal power level within the RF signal path is detected during a mute period in which transmission of an RF signal through the output antenna is disabled. The first and second detected RF signal power levels are then compared, which provides an indication of signal leakage, and thus oscillation.Type: ApplicationFiled: September 16, 2004Publication date: June 2, 2005Applicant: SPOTWAVE WIRELESS INC.Inventors: Steve Allen, Marc Colledan

Patent number: 6889033Abstract: An intelligent gain controller operates to control the gain in each one of wideband uplink and downlink signal paths. Weak desired signals, within each wideband signal path, are detected using a narrowband down converter and detector, and these desired signals monitored by the micro controller. Based on the monitored signals, the micro controller operates, under control of suitable software implementing an Adaptive Control Algorithm, to adjust the gain in each of the uplink and downlink paths in order to dynamically optimize performance.Type: GrantFiled: May 29, 2001Date of Patent: May 3, 2005Assignee: Spotwave Wireless Inc.Inventor: David Bongfeldt

Publication number: 20040156097Abstract: An intelligent gain controller (IGC) for an on-frequency repeater includes a broadband gain controller (GC) for amplifying a broadband radio frequency (RF) signal within a broadband signal path of the repeater. A narrowband receiver isolates a narrowband signal within the broadband RF signal. A processor determines a power level of the narrowband signal, and controls the gain of the broadband GC in accordance with the determined power level.Type: ApplicationFiled: February 6, 2003Publication date: August 12, 2004Applicant: Spotwave Wireless Inc.Inventors: Mike Roper, Steve Allen, Colin Kellett

Publication number: 20040097189Abstract: An adaptive personal repeater transparently mediates signaling between a wireless communications device (WCD) and a wireless communications network. The repeater includes a Directional Donor Unit (DDU) and a Subscriber Coverage Unit (SCU). The DDU maintains a network link with a transceiver (base station) of the wireless communications network. The SCU maintains a local link with the WCD within a personal wireless space of the repeater. The SCU generally includes, means for detecting respective uplink and downlink channel frequencies of the wireless communications device, and control means for controlling at least the SCU to selectively receive and transmit signals within the detected uplink and downlink channel frequencies. Total system gain is divided between the DDU and the SCU, so that a separate gain and system control unit is not required. This division of system gain also enables high-performance on-frequency repeater functionality to be obtained without the use of high-cost components.Type: ApplicationFiled: March 16, 2001Publication date: May 20, 2004Applicant: SPOTWAVE WIRELESS, INC.Inventors: David Bongfeldt, Paul Simpson, Shane Young

Publication number: 20040095992Abstract: A system provides evaluation of stability of an on-frequency repeater. A unique signature is imposed on RF signals transmitted by the repeater, and RF signals received by the repeater are analyzed to detect signal components corresponding to the signature. The signature signal is composed of a sequential series of signal pulses separated by a quiescent period. Respective transmit and quiescent power levels of signal components of the input signal received by the repeater are detected. These power levels are then used to estimate the system stability.Type: ApplicationFiled: November 20, 2002Publication date: May 20, 2004Applicant: Spotwave Wireless Inc.Inventor: Randy Balaberda
