  • Patent number: 7869822
    Abstract: The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

  • Patent number: 7869791
    Abstract: A secondary Ethernet-like wireless communication system overlapped by a dominant Ethernet-like wireless communication system, and including radio access and communication for activation, association, and authentication of a wireless device in the secondary Ethernet-like wireless communication system. An automated private service activation (APSA) port is used for accepting access and communication requests of a wireless device seeking activation, association and authentication in the secondary Ethernet-like wireless communication system. The APSA port provides an access and communication channel for radiating signals at a level exceeding a signal level of the access and communication channel only within limited spatial constraints. In addition the APSA port provides space for receiving the wireless device for activation and communication in the secondary Ethernet-like wireless communication system.

  • Patent number: 7840180
    Abstract: A system includes a satellite fleet (102, FIG. 1), in which each satellite receives uplink signals from an uplink hub (104), and transmits downlink signals in at least one directed beam (112). In an embodiment, downlink signals include television content, which is transmitted within a frequency range between about 3.7 and 4.2 Gigahertz. The satellites follow Molniya orbits (1001-1006, FIG. 10), orbit nodes are equally separated, and the satellite phasing is maintained to provide continuous communication within a coverage area. A system also includes user equipment systems (1300, FIG. 13), which include highly-directional, non-tracking antennas (1302) adapted to receive the downlink signals. In an embodiment, a method includes the satellites maintaining orbit phasings, with respect to other satellites, so that the satellite enters an active orbit segment and initiates transmission of downlink signals as a second satellite exits an active orbit segment and ceases transmission of the downlink signals.

  • Patent number: 7831265
    Abstract: A system for a mobile wireless communications device configured to stream video to a peer device over a mobile wireless network, the device configured to increase the radio channel capacity between the wireless communication devices and the network to allow faster video encoding and transmission. The video transmitting device receives measurements on radio conditions related to the radio channels carrying the video and determines if the radio conditions can support an increased channel capacity. If so, the transmitting device sends a request to the network to increase capacity on the radio channels. If the network determines that the other resources transporting the video can support an increase in traffic resulting from an increase in the radio channel capacity, then the network sends orders to carry out a radio channel capacity increase.

  • Patent number: 7826862
    Abstract: Methods and systems are provided for determining the location of a first wireless device (e.g., a mobile unit) within a wireless network comprising a second wireless device (e.g., an access point). The method includes determining a signal strength contour associated with RF communication between the access point and the mobile unit, and adding a correction factor to the signal strength contour to produce a corrected signal strength contour, wherein the correction factor includes the sums of the differences between the transmit power and the antenna gain associated with the mobile unit and the access point. In an alternate scheme involving stored fingerprint data, a correction factor is introduced based on the differences between antenna gains and transmit power associated with the mobile unit under consideration and the mobile unit used for generating the fingerprint data. The systems and methods disclosed herein are applicable, for example, to networks operating in accordance with 802.
