SAS-CBSD Interface

aid: federated-wireless:sas-cbsd-interface
name: SAS-CBSD Interface
description: The regulated Spectrum Access System to CBSD protocol interface Federated Wireless operates
  as an FCC-certified SAS administrator. The protocol — registration, spectrum inquiry, grant, heartbeat,
  relinquishment and deregistration — is defined by Wireless Innovation Forum WINNF-TS-0016 and FCC 47
  CFR Part 96, not by Federated Wireless; the company implements it and markets a "Deregistration API"
  from it. The interface is mutual-TLS and restricted to registered CBSD operators, so it is not reachable
  from the public internet and no contract is published.

  base_url_note: The host exists and resolves to company-controlled AWS infrastructure, but no handshake
    was completed. The protocol it serves is the standards body's specification, which is deliberately
    NOT saved into openapi/ or elsewhere in this repo — it is not a Federated Wireless contract.
