  • Patent number: 7450904
    Abstract: A method for changing a channel in a wireless local area network (WLAN) to alleviate congestion and high interference levels, the WLAN having an access point (AP) and at least one station, begins by determining a list of candidate channels. A channel is selected from the candidate list and is evaluated against predetermined criteria. If the selected channel meets the predetermined criteria, then all of the stations communicating with the AP are disassociated and the AP is changed to the selected channel. If the selected channel does not meet the predetermined criteria, then the selected channel is removed from the candidate list and the selecting step is repeated if there are additional candidate channels.

  • Patent number: 7406330
    Abstract: An IP PBX system that serves enterprise telephones via a landline IP network connection is be expanded to serve cellular wireless communication devices (WCD) via a cellular wireless carrier's radio access network (RAN). Calls to and from the cellular WCD are connected through the cellular carrier's RAN and the IP PBX system, so that the IP PBX system can control and manage the calls just as the IP PBX would control and manage calls involving other extensions on the IP PBX. A cellular WCD thereby becomes an IP PBX client station, i.e., an extension on the IP PBX system. As such, the cellular WCD can seamlessly benefit from many of the same IP PBX features that other more conventional IP PBX client stations (e.g., desk phones) enjoy.

  • Patent number: 7376391
    Abstract: Data encoded in packets modulated onto a carrier wave is transmitted between a base station and a transponder. Each packet includes a header section containing at least a reference symbol, and a further section such as a data section. In the transponder, the time duration of the reference symbol is determined, and a parameter is adjusted dependent on the determined duration. The parameter determines at least a property, such as the time resolution, of the encoding and/or decoding operation, and may be the clock frequency of a counter circuit or the charging current of an RC-circuit used to determine the duration of the symbols. The parameter may initially be set to a minimum default value, which is increased if the determined duration is less than or equal to a specified threshold. Thereby, power consumption is minimized while ensuring reliable encoding and decoding over a large range of transmission distances.

  • Patent number: 7340261
    Abstract: A method and apparatus for providing a cellular zone is disclosed. A communication link connects a cellular base station and a wireless access point. A typical communication link can be a wire-based communication network, such as the Internet, using IP telephony protocol. The wireless access point communicates with a cell phone over a cellular frequency and thereby establishes the cellular zone. Where the area of the cellular zone and the coverage area of the cellular base station overlap, continuous arbitration is performed to select a communications channel. The strength of a first signal received from the cellular base station is compared to the strength of a second signal received from the wireless access point. Selection criteria include signal strength and a time-oriented criteria to maintain continuity of communication channel.

  • Patent number: 7336958
    Abstract: A data transmission path establishing method for establishing a data transmission path from each device to a base station independently to thereby form a network with small devices which are required to consume lower amounts of power such as sensors, a radio communication network system and a sensor network system. A base station transmits detection signals to a plurality of radio devices. Each of the radio devices which have received the detection signal transmits detection response signals each including an identifier that uniquely identifies the device and doubling as a response signal and a detection signal for another radio device. Having received the detection response signal from a radio device, the base station recognizes the radio device as a radio device belonging to the station based on the identifier included in the detection response signal.
