  • Publication number: 20200059931
    Abstract: A system for ESC protection includes a spectrum access system (SAS) configured to allocate a frequency band in the system and at least one Citizens Broadband Radio Service device (CBSD) communicatively coupled to the SAS and configured to provide wireless service to UEs. The system also includes at least one ESC communicatively coupled to the SAS and configured to detect RADAR signals from offshore RADAR devices. The SAS is configured to assign grants to the at least one CBSD such that the aggregate signal energy received at the ESC does not cross an overload threshold, as calculated by the SAS. The ESC is configured to detect an aggregate signal energy received at the ESC, and trigger, in response to the aggregate signal energy exceeding the overload threshold, an operation that suspends transmission of at least one CBSD or moves at least one CBSD to a different frequency channel.

  • Publication number: 20200057225
    Abstract: A system for improved cable management is disclosed in several example embodiments. The disclosed embodiments describe example structures for supporting cables, for example telecommunications and fiber optic cables, within a cable storage cabinet. The disclosed embodiments also describe a door for a cable storage cabinet. The example door includes a hinge control and handle system which allows the door to be opened along either side to therefore allow the door to be opened either way from a single handle. The disclosed embodiments also describes an indicator system which informs a user when the door for the cable storage cabinet is in either a closed position or an open position. Each of these embodiments improves the utility and safety of cable management, particularly within cable storage cabinets.

  • Patent number: 10567095
    Abstract: A waveform generator includes circuitry configured to: generate a digital representation of a pulse and apply the digital representation of the pulse to a digital interface of a radio system configured to propagate the pulse and convert the digital representation of the pulse to a radio frequency signal transmitted at the antenna; and mark the digital representation of the pulse with respect to a frame of digital data with a marker. Measurement of when the pulse occurs in the radio frequency signal based on the marker occurs by a spectrum analyzer. Determination occurs of a downlink propagation delay for the radio system between application of the digital representation of the pulse at the digital interface and transmission of the radio frequency signal at the antenna.

  • Patent number: 10566700
    Abstract: In one embodiment, a sub-reflector assembly for a reflector antenna has (i) a waveguide transition at a waveguide end of the sub-reflector assembly and configured to fit within a waveguide, (ii) a dielectric radiator connected to the waveguide transition and extending both laterally and back towards the waveguide end of the sub-reflector assembly, and (iii) a sub-reflector connected to the dielectric radiator. By configuring the dielectric radiator to extend both laterally and back towards the dielectric end of the assembly, radiated energy from the waveguide is directed such that the sub-reflector assembly can be used with shallow reflector dishes (e.g., F/D ratio greater than 0.25) and still achieve sufficiently high directivity.

  • Publication number: 20200053569
    Abstract: Techniques are provided for more accurately determining interference contribution at a point in a neighborhood of a time division duplexing (TDD) system operating in shared frequency spectrum. If at least one TDD radio, of a TDD system, is in the neighborhood, then determine a largest interference level, at the point in the shared frequency spectrum, by a TDD radio of the TDD system, where the TDD radio is in the region around the point. The largest interference level is selected as the aggregate interference contribution of the TDD system for interference analysis in the shared spectrum at the point.
