The 3.5 GHz Band Today

• 3550-3650 MHz– Federal radars

– Fixed Satellite Services (FSS)

• 3650-3700 MHz– FSS

– WiMAX including utility networks

– IEEE 802.11y

• Exclusion zones– Naval radars

– FSS

Footnote US349: The band 3650-3700 MHz is also allocated to the Federal radiolocation service on a non-interference basis for use by ship stations located at least 44 nautical miles in off-shore ocean areas on the condition that harmful interference is not caused to non-Federal operations.

Agenda

FCC 15-47 Report & Order• Final rules for operation in this band

• Three level spectrum sharing– Spectrum Access System (SAS) database control

– Licensed incumbents– Part 96: Priority Access Licenses (PALs) and General Authorized Access (GAA)

• Changes from FCC 12-148 NPRM– 3-year PAL non renewable term vs 1-year renewable 5 times

– Federal exclusion zones reduced by 77%

– No 5-year limit on grandfathered FSS

– Addition of Environmental Sensing Capability (ESC)

– New categories:• Category A CBSDs for lower-power (e.g., small cell)

• Category B CBSDs, authorized for higher-power, directional, higher-gain use

– No reservation for Contained Access Facilities (“CAFs”).

Agenda

The Tiers

• First Tier - Incumbents– Federal users

– Fixed Satellite Services (FSS)

• Second Tier – Priority Licenses (PALs)– Must not interfere with Tier 1

– 10 MHz channels in the 3550-3650 MHz band [none in 3650-3700 MHz]• On a census-tract basis, for three-year terms, no option to renew

• Dynamically assigned via Spectrum Access System (SAS)

• A maximum of 70 MHz in any census tract

– Licensees may hold a maximum of four licenses in any area, i.e. 40 MHz

• Third Tier – General Authorized Access – Must not interfere with Tiers 1 and 2

– License-by-rule framework

– May access PA spectrum when it is not in “use”

Agenda

FCC 15-47 Second FNPRM

• Defining “Use” of PAL Frequencies– What constitutes “use”?

• Can a PAL be used as a guard band?

• Can a PAL be used to exclude GAA use?

• Use-or-share requirement

• Implementing Secondary Markets in PALs

• Optimizing Protections for FSS– In-band

– Out of band

Agenda

Potential Comments

• Report & Order– Would require a Petition for Reconsideration, a very high bar

– Explanation for inconsistencies in protected FSS site listings• Between FCC 05-56 and FCC 14-49• Between FCC 05-56 and http://transition.fcc.gov/ib/sd/3650/grandftr.pdf

• Second FNPRM– Defining “Use” of PAL Frequencies

– Implementing Secondary Markets in PALs

– Optimizing Protections for FSS• In-band

• Out of band
