Abstract This presentation is a description of the FCC proceeding that enables sharing of the 3.5 GHz band, and suggestions for Comments that the Regulatory SC could file. Rich Kennedy, MediaTek
Agenda • The 3.5 GHz band • FCC 15-47 summary • The Report & Order (R&O) • The Second Further Notice of Proposed Rulemaking (FNPRM) • Usage Categories • Licensed Incumbents • FCC Part 96 – Citizen Band Radio Service • Priority Access Licenses • General Authorized Access • Potential Comments • R&O • Second FNPRM Rich Kennedy, MediaTek
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 Rich Kennedy, MediaTek
The 3.5 GHz Band Rich Kennedy, MediaTek
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.

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-gainuse • No reservation for Contained Access Facilities (“CAFs”). Rich Kennedy, MediaTek
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” Rich Kennedy, MediaTek
TX Power Limits Rich Kennedy, MediaTek
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 Rich Kennedy, MediaTek
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 Rich Kennedy, MediaTek
