8. CBRS NPRM Adopted October 24
Seeks comment on changes to PAL license terms:
License Area (Census Tracts?, PEAs? Counties?)
10 years terms
Expectation of renewal
Allow partitioning / disaggregation
Splitting up the 10 MHz licenses into smaller license areas to be planned
by the SAS to enable sub-licensing.
Technical rule changes:
Revisions for facilitating wider bandwidths
Remove obligation to publish registration data
T-Mobile request for PALs across the band is denied in the Order.

CBSD: Citizens Broadband Radio Service Devices
Basestation / eNodeB
May interface SAS directly or via Proxy / Network Manager
SAS: Spectrum Access System Database
Allocates allowed spectrum and maximum transmission power to CBSDs based on location
Provides interference protection: PAL/GAA to Incumbents, PAL to PAL, GAA to PAL
ESC: Environmental Sensing Capability
Detects signals from Incumbents and informs SAS
SAS re-allocates CBSDs as needed

17. 5G Spectrum – C-BAND Potential for alignment with CBRS band
Under consideration across the world
Propagation and speed
Ericsson’s comments:
FCC should pursue licensed spectrum using market-based mechanisms to clear the GHz band
Pursue unlicensed technology in 5.9 – 6.4 GHz and licensed technology in 6.4 – 7.1 GHz provided incumbent fixed operations are protected across 6 GHz
Proposal for FCC and NTIA to work to make 7.1 – 8.5 GHz a shared band between commercial and federal users of fixed services
Todd Gore

18. MID-BAND COALITION
Diverse membership, including operators, trade associations, manufacturers, and the Wi-Fi community.
Focus on 3.7 – 4.2 GHz as a licensed band, 5.9 – GHz unlicensed, and a question about how to treat – GHz.
Sensitivities over fixed links in the 6 GHz band and incumbent satellite users.
Intel/Intelsat proposal: market-based approach to allow terrestrial access to important markets.
Apple, Broadcom, Cisco, Comsearch, Ericsson, Hewlett-Packard Enterprise, Intel, Google and Alphabet Access, Samsung, T-Mobile, and Verizon
