Patent number: 8634826Abstract: A method and corresponding system for use of a femtocell in a vehicle (an “in-vehicle femtocell”) to help limit operation of a wireless communication device (WCD) positioned in the vehicle. In one implementation, registration (or registration attempts) of one or more WCDs with an in-vehicle femtocell may be used as a basis to trigger limitations on certain WCD functions in a vehicle, such as to prevent a WCD from providing text-messaging service for instance. In another implementation, a WCD may receive a signal from an in-vehicle femtocell and in response to the signal, the WCD may register with the femtocell to be served with wireless communication service by the femtocell. In addition to registering with the femtocell, the WCD may limit certain of its own functions while it is in the vehicle and being served with wireless communication service by the femtocell.Type: GrantFiled: March 26, 2010Date of Patent: January 21, 2014Assignee: Sprint Spectrum L.P.Inventors: Warren B.

The receiver is configured to identify a received network reservation message that inhibits access to a first wireless network for an interval defined in the reservation message. The network activity monitor is configured to monitor wireless activity on the first wireless network during the interval. The network access scheduler is configured to determine whether the reservation message prevents conflict of the first wireless network with a coexisting wireless network during the interval, and to schedule, based on a determination that the reservation message prevents conflict with the coexisting wireless network, the wireless apparatus to transmit on the first wireless network during the interval to a wireless device other than a wireless device identified in the reservation message.Type: GrantFiled: March 14, 2011Date of Patent: November 19, 2013Assignee: Texas Instruments IncorporatedInventors: Yanjun Sun, Ariton E.

Patent number: 8583047Abstract: A system, apparatus and method is disclosed for multiband wireless communication. Frequency bands and/or transmission formats are identified as available within a range for wireless communication. Signal quality metrics for each frequency band are evaluated by a receiver to identify qualified frequency bands. The qualified frequency bands can be ranked according to one or more signal quality metrics, where the list of qualified bands can be communicated to a transmitter. The transmitter is arranged to evaluate the list of qualified bands and select a communication method based on the available frequency bands and a selected communication optimization scenario. Multiple frequency bands and communication methods can be utilized by the transmitter such that a combination of licensed, unlicensed, semilicensed, and overlapped frequency bands can be simultaneously used for communication.Type: GrantFiled: July 2, 2012Date of Patent: November 12, 2013Assignee: T-Mobile USA, Inc.Inventors: Hongliang Zhang, Mark McDiarmid

Patent number: 8583197Abstract: Aspects of a method and system for sharing antennas for high frequency and low frequency applications may include configuring a multi-frequency antenna system by coupling a plurality of antennas together communicatively via one or more frequency-dependent coupling elements. Radio signals may be received and/or transmitted on one or more radio frequencies via said configured multi-frequency antenna system. The one or more frequency-dependent coupling elements may be frequency-tunable, and may comprise microstrips, transmission lines, and/or RLC circuits. The multi-frequency antenna system may be configured for concurrent operation or time-division duplex operation during the transmitting and/or the receiving. The one or more radio frequencies may operate concurrently or in time-division duplex. The radio signals for transmission may be generated in one or more radio frequency front-ends, and the received radio signals may be demodulated in one or more radio frequency front-ends.Type: GrantFiled: December 12, 2007Date of Patent: November 12, 2013Assignee: Broadcom CorporationInventor: Ahmadreza Rofougaran

Publication number: 20130295989Abstract: An apparatus has a first communication module and a second communication module. The first communication module is compatible with a first wireless communication technology, and the second communication module is compatible with a second wireless communication technology that differs from the first wireless communication technology. Transmissions by the second communication module may contribute to interference at the first communication module. The first communication module refrains from advertising support for any data rate that is not expected to be sufficiently resilient in the face of interference caused by transmissions from the second communication module.Type: ApplicationFiled: May 3, 2012Publication date: November 7, 2013Applicant: RESEARCH IN MOTION LIMITEDInventors: Mohammed Nawaf SMADI, Jianfeng WENG
