  • Patent number: 10225842
    Abstract: Aspects of the subject disclosure may include, for example, a wireless communication node that receives instructions in a control channel directing it to utilize a spectral segment at a first carrier frequency to communicate with a mobile communication device. Responsive to the instructions, the wireless communication node receives a modulated signal in the spectral segment at a second carrier frequency from the base station, the modulated signal including communications data provided by the base station. The wireless communication node down-shifts the modulated signal at the second carrier frequency to the first carrier frequency, and wirelessly transmits the modulated signal at the first carrier frequency to the mobile communication device. Other embodiments are disclosed.

  • Publication number: 20190069296
    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.

  • Publication number: 20190059088
    Abstract: Aspects of the subject disclosure may include, for example, a repeater device having a first coupler to extract downstream channel signals from first guided electromagnetic waves bound to a transmission medium of a guided wave communication system.

  • Patent number: 10211916
    Abstract: Aspects of the subject disclosure may include, for example, a transmission system having a coupling device, a bypass circuit, a memory and a processor.
