Baseline specs complete for 3.5 GHz Citizens Broadband Radio Service

Ten baseline specifications for commercial operations within the 3.5 GHz Citizens Broadband Radio Service (CBRS) band are now ready to go.

  • CBRS Operational and Functional Requirements
  • CBRS Communications Security Technical Specification
  • CBRS Operational Security Technical Specification
  • SAS to CBSD Protocol Specification
  • SAS to SAS Protocol Specification
  • SAS Test and Certification Specification
  • PAL Database Specification 
  • CBRS PKI Certificate Policy
  • CBSD Test and Certification Specification
  • CPI Accreditation Standard

In April 2015, the U.S. Federal Communications Commission (FCC) adopted rules for CBRS, which opens 150 MHz of spectrum (3550-3700 MHz) for commercial use — while providing necessary protection of incumbent users of the band. Spectrum access is actively coordinated based on priority and granular location, making previously allocated spectrum available to new entrants and services.

The Wireless Innovation Forum (WInnForum) said this watershed event allows the finalization of CBRS products already in various levels of testing and sets the stage for the rollout of commercial CBRS networks.

Google: "Completion of these standards demonstrates that it is now possible to make major changes in how we approach managing spectrum resources to provide the abundant bandwidth essential to our society,” said Eric Schmidt, Executive Chairman of Google parent company Alphabet Inc. “This accomplishment shows that flexible, cloud-based management can enable spectrum to be used for many purposes simultaneously, and relegate the exclusive, command and control vision of spectrum allocation to history."

Nokia: “The CBRS shared spectrum band has been made available in the US, offering 150MHz of spectrum in a continuous block. This spectrum will enable cost effective coverage and capacity expansion at large scale. Completion of detailed specifications of the CBRS Baseline Standards, while working with various contributors from multiple companies, is a monumental milestone achievement,” said Ricky Corker, Executive Vice President, Nokia. “I would like to congratulate all members of the WInnForum in achieving this milestone. CBRS, using a unique 3-tiered shared spectrum approach, promises efficient use of spectrum, and I cannot wait to see the successful rollout in the US.”

Ericsson: “The completion of the CBRS Baseline Standards represents an important milestone for spectrum sharing, unleashing the band’s potential for innovation. Ericsson’s commitment to supplying LTE equipment for the band will ensure strong commercial support for the ecosystem,” said Paul Challoner, VP Network Product Solutions, Ericsson. “The wholehearted cooperation of incumbents, including the DoD, the NTIA, the fixed satellite industry, and the commitment of the FCC to the success of the CBRS is to be acknowledged. Ericsson looks forward to speedy certification of the SAS and ESC and a smooth transition to commercial operation of LTE nationwide in the 3.5 GHz shared spectrum band.”

Verizon: “Verizon is pleased to see the WInnForum make timely progress in publishing CBRS protocol and test specifications. These are critical steps in the testing of CBRS SAS systems, ESC systems, and CBSD devices and the eventual deployment of network infrastructure and consumer devices on this highly desirable CBRS spectrum,” says Ed Chan, Chief Technology Architect and Network Planning (NYSE: VZ). He added, “Access to additional wireless spectrum is essential for providers who want to deliver on the promise of next generation technologies. We believe the FCC’s new CBRS shared spectrum approach is an innovative and responsible way to leverage all the available spectrum resources in the U.S. We look forward to offering innovative new products and services in this new shared CBRS spectrum.”
