Patent number: 8588201Abstract: Sub-channelization gain in an OFDMA-based wireless channel is enhanced by utilizing packet fragmentation when implementing a constant bit rate (CBR) real time (RT) packet application. A packet that would normally be transmitted using multiple sub-channels in a single OFDMA frame may be fragmented and delivered through the wireless channel over multiple frames. Because fewer sub-channels are used within each frame, sub-channelization gain is enhanced.Type: GrantFiled: November 15, 2005Date of Patent: November 19, 2013Assignee: Intel CorporationInventors: Muthaiah Venkatachalam, Masud Kibria, Shailender Timiri

Patent number: 7792093Abstract: An analog telephone adapter (ATA) having a subscriber identity component in the format of a Subscriber Identity Module (SIM) that couples a telephone to a cellular network via Voice over Internet Protocol (VoIP), thereby allowing a cellular service provider to provide an alternative communication service for the home or business. Instead of using the plain old telephone service, a subscriber can plug their analog telephone into the SIM-enabled ATA (SIM-ATA) and receive telephone service from a cellular service provider, eliminating or reducing the need for a traditional Local Exchange Carrier. The SIM-ATA converts signals from analog to digital, and vice-versa. Once the analog telephone signal has been converted to digital, an IP-based protocol (e.g., VoIP) can be used to transmit the telephone call over a digital network. The cellular service provider can then track usage and bill the subscriber accordingly.Type: GrantFiled: November 15, 2004Date of Patent: September 7, 2010Assignee: AT&T Mobility II, LLCInventors: John E. Myhre, Masud Kibria, James F. Whitehead

Patent number: 7035646Abstract: A mobile station communicates with both a cellular network, by which it is assigned a mobile identification number, and to a cordless cellular base station utilizing the same cellular frequency range and communications protocol. The cordless cellular base station is preferably connected to a public switched telephone network and is assigned a landline number. The cordless cellular base station acts as a conduit between the mobile station and the public switched telephone network. When the mobile station comes within range of a cordless cellular base station, it deregisters automatically from the cellular network and register with the cordless cellular base station. Once the mobile station is communicating with the cordless cellular base station, the cordless cellular base station communicates with the cellular network to instruct the cellular network to route all calls for mobile identification number to the cordless cellular base station's landline number.Type: GrantFiled: August 22, 2003Date of Patent: April 25, 2006Assignee: Cingular Wireless II, LLCInventors: Michael A.

Publication number: 20040203737Abstract: A system and method for allowing a mobile telephone or mobile terminal to interact with its wireless telephone/data service, including conventional 2G and 3G systems (hereinafter the “wireless network”), and also to interact with local-area services such as WLAN, BlueTooth, and personal area networks, and to communicate with and use systems and peripherals available on those networks. Since the mobile terminal is a trusted device on the wireless network, it also then acts as a gateway to allow other local-area services and devices to connect and communicate with the wireless network. The user can select, and the wireless network can determine, data services that correspond to local-area devices. Once selected, the data service is delivered to the local-area device via the wireless network and the mobile terminal.Type: ApplicationFiled: December 20, 2002Publication date: October 14, 2004Inventors: John Myhre, Venson Shaw, Masud Kibria

Patent number: 6584175Abstract: A method and apparatus for remote spectrum analysis is disclosed. A channel measurement device is configured to receive and measure the radio spectrum in a geographic location during a measurement phase of operation. A microprocessor processes the signals and stores processed data on a storage device. The channel measurement device contains a communications interface to a land line telephone network and/or a cellular telephone network. During a data transfer phase of operation, the channel measurement device sends the processed data to a remote processor via the land line or cellular telephone network. In addition, the remote processor may act as a remote user interface to control the operation of the channel measurement device. In particular, the remote processor may be used to store values for user programmable configuration parameters in a memory of the channel measurement device via the land line or cellular telephone network.Type: GrantFiled: November 12, 1999Date of Patent: June 24, 2003Assignee: AT&T Wireless Services, Inc.Inventors: Masud Kibria, Michael Allen Raffel

Patent number: 5878328Abstract: A level of system self-organization in a wireless communication system is provided using a combined design, planning and verification process to determine system organization parameters. The process determines the parameters based on a measured path loss-related characteristic, such as path loss or bit error rate, between base stations and a plurality of regions in a coverage area. For each region, the characteristic is measured to each base station irrespective of the proximity between the region and the base stations. The measured characteristics enable the prediction of signal strength received at the regions of signals transmitted by the base stations independent of the region location. Accordingly, the characteristics can be measured without information correlating the absolute geographic locations of the regions.Type: GrantFiled: December 21, 1995Date of Patent: March 2, 1999Assignee: AT&T Wireless Services, Inc.Inventors: Kapil K. Chawla, Michael Jeffrey Dunn, Masud Kibria, Michael Allen Raffel, Reinaldo A. Valenzuela

Patent number: 5732360Abstract: A remote unit has the ability to switch automatically from a public network to a non-public network comprising of private and residential base stations. In the preferred embodiment, the public network is characterized by cells with each cell having a unique identification signal. Initially, a first switchover from a public network to a non-public network requires the user to manually cause the switchover. The remote unit stores the first identification signal transmitted by the base station from which the remote unit traversed into the region covered by the non-public base station. In addition, the remote unit stores the identification signal associated with a cell of the public network previous to the current cell if the switchover occurred less than two (2) minutes from the exit of the previous cell. In this manner, the remote unit can adaptively learn as it traverses other possible paths from other cells into the region covered by the non-public base station.Type: GrantFiled: September 8, 1995Date of Patent: March 24, 1998Assignee: AT & T Wireless Services and Atmel CorpInventors: Keith Jarett, Roland E.
