FCC Sets Stage for Commercial Use of New Wireless Broadband Spectrum
New rules governing the use of the 3.5 GHz spectrum arms IoT technology providers with more viable deployment options.
CBRS Equipment Response Time Increase
Under the original rules, a CBSD had 60 seconds to cease transmission, move to another frequency range or change its power level once it received a command from a Spectrum Access System (SAS) alerting it to a federal system emitting an interferring signal nearby. Acknowledging comments asserting that 60 seconds is too short a time for operators to effectively re-configure their networks in response to reported interference, the FCC increased the reconfiguration timeframe to 300 seconds.

"Use" of PA Frequencies Defined
First, PA licensees may self-report to the SAS their "PAL Protection Areas" on the basis of their actual network deployment. Second, to establish a consistent objective maximum PAL Protection Area, an SAS will use a consistent model to define a default -96 dBm/10 MHz protection contour.
The FCC encourages PA licensees to work with the SAS to restrict their PAL Protection areas to less than the above-described default protection contour. The idea is that more spectrum will be available for other users, which will, in turn, permit licensees to lease more spectrum, as described below. PA licensees may freely alter their reported PAL Protection Areas during their license terms by reporting such changes to the SAS.
Spectrum Leasing Permitted
The basic procedure requires the following: the licensee and lessee must complete an FCC Form 608 through the FCC's database; the lessee must certify that it meets the basic FCC requirements to hold a license; the licensee must notify the SAS of the leasing arrangement (providing a substantial amount of information); and the SAS must be able to confirm that the lessee provided the required certification to the FCC, the lease will not violate the 40 MHz spectrum aggregation limit for the specific census tract, and the lease area is within the licensee's service area, but outside of its PAL Protection Area.
