CBRS Status Summary

as of July 11, 2018
 
Gating Criteria for Commercial CBRS Operations
  • Completion of CBRS baseline  industry standards (completed 1Q18)
  • Availability of FCC-certified CBRS devices (expected no earlier than 3Q18)
  • Certification of one or more Spectrum Access Systems (expected no earlier than 4Q18)
    • There are six conditionally-approved SAS Administrators awaiting certification; four additional applications were filed after the first SAS Administrator application deadline.
  • Certified Professional Installer (CPI)
    • CPI is required for Category B and non-geolocating Category A
    • Accreditation of CPI training programs (expected no earlier than 3Q18)
    • Certification of Professional Installers (expected no earlier than 3Q18)
  • Accreditation of PKI Root of Trust Certificate Authorities (complete)
    • Three companies have been accredited: Digicert, Insta Defsec, and Kyrio

Coastal Sensor Networks (ESC)

  • “Environmental Sensing Capability” (ESC) to detect Navy radar operations will be required before any CBRS operation within 3550-3650 MHz near the coasts. 
  • Expect certification of ESC systems on same timescale as SAS (i.e., no earlier than 4Q18)
    • There are four conditionally approved ESC Operators awaiting certification; one additional application was filed after the first ESC Operator application deadline
  • Full deployment of ESC systems will take time
    • Require (very roughly) 200 sensor nodes
    • In the meantime, CBRS operation is allowed in protected areas under partial ESC deployments
  • Deployment timescale will be dictated by wireless siting issues, hardware installation, etc.

General Authorized Access (GAA) commercial operation

  • May begin as soon as devices and at least one SAS are certified (i.e., no earlier than 4Q18)

Priority Access License (PAL) commercial operation

  • Requires PAL auction (and availability of a certified SAS)
  • No current schedule for PAL auction
    • Requires FCC Public Notice process, auction design, and completion of auction process
    • No timeline, but expected in 2019

Regulatory Updates

  • FCC Notice of Proposed Rulemaking to deal with petitions mostly focusing on PAL license issues
    • Requests expanding license areas (Partial Economic Areas instead of census tracts), extending license terms (~10 years instead of three), and expectation of renewal (instead of re-auction at the end of each license term), among the key issues
  • Resolution of NPRM expected no earlier than late ~3Q18. The issues don’t directly impact SAS and commercial operations (i.e., the pending NPRM need not delay initial commercial service, especially in the GAA tier)
