The Wireless Innovation Forum (WInnForum) has commended the 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 company said.
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.
