  • Patent number: 10582419
    Abstract: A mobile communication device generates a respective request (such as a wireless communication) to access a network. An access point supporting communications over multiple carrier frequency bands receives the request from the mobile communication device to establish a wireless connection. A connection manager associated with the access point analyzes current load conditions associated with other mobile communication devices communicating with the access point over the multiple carrier frequency bands. Based at least in part on the current load conditions, the connection manager selects a carrier frequency band from the multiple carrier frequency bands. The connection manager initiates notification to the mobile communication device to connect to the access point using the selected carrier frequency band.

  • Patent number: 10554350
    Abstract: A communication management resource associated with a wireless access point in a network environment allocates use of a wireless channel and sub-channels over time to multiple communication devices in communication with the wireless access point. For example, during use, from a first communication device of the multiple communication devices competing for wireless bandwidth, the communication management resource receives a request for allocation of wireless bandwidth to communicate over a wireless communication link with the wireless access point. Subsequent to receiving the request, the communication management resource identifies an appropriate amount of wireless bandwidth suitable to satisfy the request for bandwidth from the first communication device.

  • Patent number: 10165620
    Abstract: According to one configuration, an access point control resource receives channel allocation information indicating a change to allocation of channels in a wireless band currently used by multiple wireless access points to communicate with multiple communication devices in a network. The access point control resource uses the channel allocation information to identify a particular wireless channel (such as a de-allocated wireless channel) to be terminated from use by the multiple wireless access points. In accordance with the channel allocation information, when vacating use of the de-allocated channel, the access point control resource controls an order of terminating use of the particular wireless channel by the multiple wireless access points.

  • Publication number: 20160157281
    Abstract: A communication resource generates a communication to indicate a primary identifier assigned to a wireless network. Additionally, the communication resource populates the communication with data indicating that the wireless network includes multiple available wireless sub-networks. The communication resource broadcasts the communication as a wireless signal in an airspace. A mobile communication device receives the broadcasted wireless signal. The mobile communication device processes the received wireless signal to learn of a primary identifier assigned to the available wireless network. The mobile communication device further processes the data received in the wireless communication to learn of secondary identifiers (which may require retrieval or be located in the received communication) specifying the different wireless sub-networks that are available.

  • Patent number: 8355747
    Abstract: Systems and methods for dual wireless communication technology communications are provided. A mobile station communicates with two transceivers of a base site, where each transceiver operates according to a different wireless communication technology. The mobile station can communicate uplink and downlink control information with a first transceiver of the base site while also communicating uplink and downlink data with a second transceiver. Alternatively, the mobile station may transmit uplink transmissions only to a first transceiver and only receive downlink transmissions from a second transceiver.

  • Patent number: 8175596
    Abstract: Systems and methods of extending base station coverage are provided. Idle mode mobile stations supported by a base station are identified, and at least one of the idle mode mobile stations is selected based on a location of the at least one idle mode mobile station. A communication with an active mode mobile station that is associated with the at least one idle mode mobile station is established. The active mode mobile station is not able to directly receive communications from the base station, and the identification and selection of idle mode mobile stations and the establishment of the communication are performed by the base station.

  • Patent number: 8031669
    Abstract: Systems and methods for enhancing the capacity of base stations are provided. A base station can operate in a time division duplex mode within a first frequency band. When a second frequency band is acquired for the base station's geographic region, a duplexer can be added to the base station. The base station can then operate in a frequency division duplex mode, where the first frequency band is used for base station downlink transmissions and the second frequency band is used for uplink transmissions.

  • Publication number: 20080108367
    Abstract: Systems and methods for supporting multiple wireless communication technologies within a cell are provided. A base station can transmit a second wireless communication technology in a smaller coverage than the coverage of the first wireless communication technology, thereby producing an underlay-overlay cell radiation pattern. Whether a mobile station communicates with the base station using the first or second wireless communication technology can be based on a comparison of signal quality measures for the mobile station, or any other performance metric with a fixed or dynamic threshold.
