Wireless Innovation Forum Applauds Recent FCC Order Allowing Use of Dynamic Protection Areas

Action an important development in advancement and early
commercialization of the CBRS ecosystem

Wireless Innovation Forum
(WInnForum) commended today the May 22 FCC
order by conditional waiver of certain rules allowing each Spectrum
Access System (SAS) administrator in the 3.5 GHz CBRS band to choose the
use of Dynamic Protection Areas (DPAs) in the protection of Federal
Incumbent Naval radar systems. The order also allows for the conditional
operation of CBRS Category B devices before full deployment of certified
Environmental Sensing Capability (ESC) systems. This will allow
commercial operation in the band more quickly than projected, promoting
efficient spectrum use and validating the investment the wireless
industry has made in the CBRS ecosystem.

DPAs are a new concept for Federal incumbent protection in the CBRS
Band. They were engineered through the collaboration of industry and
government organizations along with the National Telecommunications and
Information Administration (NTIA). The DPA process helps to resolve
complex technical issues further advancing the CBRS dynamic sharing
principles and accurately protecting Federal incumbents. It offers an
option to the present static exclusion zones originally provided for in
FCC rules. Instead, DPAs offer smaller protection areas that are
identified and activated when the ESC sensors detect Naval radar systems
in operation. Based on this, the SAS provides protection to a
pre-defined protection area incorporating the operating characteristics
of the devices in proximity to the DPA.

“The WInnForum applauds the NTIA and FCC for implementing this approach
and reaching this important milestone in the development of the CBRS
ecosystem,” said Mark Gibson, WInnForum’s Regulatory Officer. “These
actions by the FCC bring more certainty to the CBRS band and will allow
higher power outdoor devices to operate in the band sooner than

WInnForum supports the development and advancement of spectrum sharing
technologies based on the three-tier architecture detailed in 3.5 GHz
CBRS Band rules defined by the FCC. The Forum recently announced the
completion of the full set of baseline standards required for WInnForum
certification of CBRS equipment. This watershed event allows the
finalization of CBRS products for official testing and sets the stage
for the rollout of commercial CBRS networks. The WInnForum Baseline
Standards can be found here: https://www.cbrs.wirelessinnovation.org.

WInnForum announced on May 29th the delivery of the Spectrum
Access System certification test code for commercial operations within
the CBRS band to the NTIA’s Institute for Telecommunication Sciences
(ITS). The test code was developed in a deeply collaborative effort by
engineers representing multiple stakeholder organizations over the last
two years. It has been developed, verified and validated by the
WInnForum Spectrum Sharing Committee’s Test and Certification Working
Group. Through this effort, engineers maximized the use of common
industry testing processes, preserving the openness of the system, while
allowing for innovation and development of the subsystems in a healthy
competitive ecosystem. Release of this code marks the beginning of the
test and certification process for prospective SASs.
