Abstract: Techniques for modelling a radio network in a geographic region utilizing shared spectra are disclosed. Population data is obtained for the geographic region. A number of radios per channel in the geographic region, N?, is determined. Candidate geographic location for radios in the geographic region are determined. For every channel in the shared spectra, at least one of a static dataset and a dynamic dataset is determined. At least one set of output data, that is a statistical characterization of the radio network, is generated using at least one of the static dataset and the dynamic dataset, to aid in design of the radio network.

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.
