  • Patent number: 10575295
    Abstract: A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

  • Patent number: 10425214
    Abstract: Scheduling and allocating resources in a millimeter wave communication system are performed by components of both the MAC and the RF front end acting in cooperation with one another. MAC components operate essential in accordance with the 802.11 standard. Signals at 2.4/5 GHz intermediate frequency (IF) output from an IF module are upconverted to an RF mmWave spectrum. The RF signals are routed to different subsector antennas and/or polarizations of a subsector antenna in order to direct the RF mmWave signal to a desired destination. Beamforming by the physical structures of antennas, direct the RF signals to a particular subsector. The combination of allocating resources within the MAC, processing within the MBI module before being upconverting to RF, together with signal switching of the RF signals, determines the destination to which signals are to be transmitted and the source from which signals are to be received.

  • Patent number: 10333612
    Abstract: A method, wireless device and computer program product for expanding the coverage of a cellular network. A wireless device (e.g., cellular telephone) is able to communicate with a base station in a cell of the cellular network over a non-cellular interface via another wireless device in a cell through the use of multi-hopping. A wireless device may request permission to communicate with the base station over a non-cellular interface via hopping off another wireless device when its signal strength is below a threshold. Alternatively, a wireless device may receive a request to communicate with the base station over a non-cellular interface via hopping off the wireless device that sent the request when that wireless device has excess capacity in its bandwidth with the base station. By enabling wireless devices to communicate with a base station in such a manner, the effective capacity of the cellular network is expanded and the effective capacity of the cellular network is improved.
