Patent number: 8565145Abstract: A method for transmitting a communication generated by an originating device to a target device using a repeating device is provided. In the method the communication is transmitted from the originating device and received at the repeating device. A repeater request sequence is transmitted from the originating device and retransmitted from the first repeating device to the target device before the repeater request sequence is received at the first repeating device.Type: GrantFiled: December 15, 2010Date of Patent: October 22, 2013Assignee: Motorola Solutions, Inc.Inventors: Shakeeb Z. Khan, Joseph J. Medvid, III, Charles R. Ruelke, Richard S. Young, Branko L. Avanic, Lorenzo Cruger, Tan V. Dinh, Mahes M. Ekanayake, Armando J. Gonzalez

Patent number: 8295825Abstract: Methods of enabling late entry into an on-going spread spectrum call are described. A late join frame replaces, and has the same size as, a traffic frame. A late join slot in the late join frame contains sufficient information in preamble and sync subframes to permit a target to join the call. The traffic slots in the late join frame replicate data such that call quality of the call is substantially unaffected if one of the remaining traffic frames is not received. The preamble and sync subframes frequencies may be the same as, or different from, preamble and sync frames frequencies during a call establishment phase of the call. If different, the preamble and sync subframes frequencies are selected from one or more frequencies. Use of the preamble and sync subframes frequencies is compensated for when selecting the traffic slot frequencies to obtain uniform utilization of the spectrum.Type: GrantFiled: November 30, 2010Date of Patent: October 23, 2012Assignee: Motorola Solutions, Inc.Inventors: Ellis A.

Patent number: 8169369Abstract: A frequency generation unit (FGU) in a communication device includes a voltage controlled oscillator (VCO), an adjustable filter having a capacitive element for wideband operation, a current source with variable gain, and chirp generation control circuitry (CGC) that is used to generate location signals. The FGU receives, from a reference device, at least one location signal control parameter that defines linear frequency slope characteristics for a location signal. The CGC configures, based on the at least one location signal control parameter, the gain and a polarity of the current source to generate a first current during a first time period for charging the capacitive element to generate a control signal that is coupled to the VCO to generate a first part of the location signal having the defined linear frequency slope characteristics, wherein the first part of the location signal is transmitted using a transceiver of the communication device.Type: GrantFiled: December 15, 2008Date of Patent: May 1, 2012Assignee: Motorola Solutions, Inc.Inventors: Armando J.

Patent number: 8131215Abstract: A reference device determines its distance from a communication device by first using a training process to determine a calibrated time delay for the communication device when the communication device is at a known distance from the reference device. The calibrated time delay is a steady state internal processing delay for the communication device. Subsequently, when the reference device is at an unknown distance from the communication device, the reference device determines the unknown distance using the previously determined calibrated time delay along with a measured signal travel time at the unknown distance.Type: GrantFiled: December 15, 2008Date of Patent: March 6, 2012Assignee: Motorola Solutions, Inc.Inventors: Charles B.
