  • Publication number: 20160353401
    Abstract: A communication cell may use a wireless in-band backhaul to route backhaul traffic to a macrocell of a carrier network such that the backhaul traffic is delivered to a core network of the carrier network. The communication cell may route backhaul traffic of user devices via the wireless in-band backhaul between the communication cell and the macrocell. The wireless in-band backhaul may take place of a dedicated backhaul between the communication cell and the core network. As the backhaul traffic is routed, if a characteristic of the wireless communication between the communication cell and the macrocell fails to meet a threshold, an antenna of the communication cell may be electrically or mechanically adjusted to improve the characteristic of the wireless communication. The adjustment of the antenna includes performing a beam forming or moving one or more antenna elements of the antenna.

  • Patent number: 9088388
    Abstract: The high quality PCS communications are enabled in environments where adjacent PCS service bands operate with out-of-band harmonics that would otherwise interfere with the system's operation. The highly bandwidth-efficient communications method combines a form of time division duplex (TDD), frequency division duplex (FDD), time division multiple access (TDMA), orthogonal frequency division multiplexing (OFDM), spatial diversity, and polarization diversity in various unique combinations. The method provides excellent fade resistance. The method enables changing a user's available bandwidth on demand by assigning additional TDMA slots during the user's session.

  • Publication number: 20150071239
    Abstract: Described herein is a radio access provider configured to communicate with wireless access devices over frequency bands. The radio access provider receives service priorities associated with active applications of the wireless communication devices. Based at least in part on the service priorities, the radio access provider selects blocks or channels from one or more of the frequency bands for a radio communication link for each of at least a subset of the wireless communication devices. The selecting may include selecting block or channels from multiple ones of the frequency bands for the radio communication link for at least one of the subset of the wireless communication devices. The selecting may also be based at least in part on signal quality metrics for the frequency bands, cross-correlations of the frequency bands, or power capacities of the wireless communication devices.

    Abstract: 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.
