lower-power (Category A) devices to operate in the band outside of exclusion zones and couldn’t authorize the use of any higher-power (Category B) devices before certification and deployment of environmental sensing capability (ESC) operators. The FCC side-stepped this requirement, letting SASs use an alternative protection methodology based on dynamic protection areas (DPAs). Every SAS will have to decide whether it will take advantage of the rule change, the FCC said. “Prior to the deployment of an ESC, a DPA-enabled SAS may authorize both Category A and Category B [devices] and will not be required to enforce Exclusion Zones in areas protected by DPAs,” the order said. “Prior to the deployment of an ESC, non-DPA-enabled SASs may only authorize Category A CBSDs outside of Exclusion Zones, consistent with the current rules.” The FCC said the revised rules will permit operators in the band to “operate both Category A and Category B [devices] in a larger portion of the country more quickly than anticipated and thereby will promote efficient spectrum use and rapid commercial deployment in the band, encourage investment, and facilitate the expeditious provision of new products and services to the public while still protecting federal operations.”
