3 Overview of Spectrum Strategy

Spectrum Strategy  Driver: Continued growth of mobile & other services  More Spectrum  National Broadband Plan  Middle Class Tax Relief & Jobs Creation Act of 2012  Presidential Memos  NTIA ten year plan  Consider potential reallocations, but becoming more difficult  Efficient Use of Spectrum:  Continue to advance technology with higher spectral efficiency  Often spectral efficiency needs to be balanced with capital efficiency  More Sharing  PCAST Report  Department of Defense Spectrum Strategy  Develop advanced spectrum sharing techniques 4

5 Efforts for More Spectrum

Advanced Wireless Service-3 (AWS-3) Paired 2155 MHz MHz with MHz; Unpaired 1695 – 1710 MHz Implementing various stages of relocation and sharing mechanism “Heavy Duty” engineering –Identify relocation bands –Sharing: Realistic vs. Worst case Required close collaboration Federal Incumbent Systems: Fixed Point-to Point Microwave Military Tactical Radio relay Air Combat Training System Precision Guided Munitions Tracking, Telemetry & Commanding Aeronautical Mobile Telemetry Video Surveillance Unmanned Aerial Systems Other Systems 6

7 Repacked TV Guard Medical Duplex Gap Repurposed Band Telemetry & For Wireless Radio Astronomy Auction First time the Commission has needed to develop band plans without knowing how much spectrum will be available! 600MHz Incentive Auction Initial Clearing Target of 126MHz is announced on April 29, 2016 Reverse Auction Bidding to start on May 31, 2016

 2 nd Order was issued in April 28, 2016  Finalized rules governing this band  Spectrum Access System (SAS) will incorporate information from the Environmental Sensing Capability (ESC) to increase available spectrum in coastal areas  Reaffirmed the regulatory approach adopted in the 3.5GHz R&O and denied several petitions for reconsiderations – Strived to establish simple rules that are implementable in the near term, while protecting DoD radar systems Navy Ship Radars Non-Federal Satellite ES FSS Federal 3.5GHz Citizens Broadband Radio Service 8

Expanding Use of the mmW Spectrum  FCC Notice of Inquiry (NoI) adopted 10/17/14  FCC Notice of Proposed Rulemaking (NPRM) adopted 10/22/2015  NPRM proposes a mix of licensed and unlicensed use in the millimeter wave spectrum, and creates opportunities for sharing among different kinds of users; fixed/mobile; federal/nonfederal; terrestrial/satellite; and carrier networks/private networks  Recommended by Technological Advisory Council ness/2015/db1023/FCC A1.pdf 16

Mobile Traffic Growth 18 US Mobile data traffic will increase by 6 fold from 2015 to 2020, mainly driven by mobile video 4G is accelerating and world is following US lead March to 5G has begin Mobile data is still a small fraction of overall data traffic In US, 4G network is carrying 81% of mobile data traffic and expect to carry 94% of mobile data traffic by 2020

Policy Considerations 19  5G is a national priority for US  We indicate which spectrum will be made available  Rely on a private sector-lead process for producing technical standards best suited for those frequencies  Flexible licensing rules to support various service models  Carrier-driven vs. new entrant vs. end-user driven network  Technical rules to take advantage of propagation characteristics of mmW bands  Enable sharing opportunities  Enhance the spectrum reuse  Create opportunities for innovators to build and deliver new services and applications to consumers

20 Other Topics

NPRM proposed to expand access to spectrum for unlicensed at 5 GHz First R&O 3/31/14 - Removed indoor-only restriction & increased permitted power for U-NII 1 Continuing to work on sharing in proposed U-NII-2B and U-NII-4 Memorandum Opinion and Order (MO&O) released on March 2, 2016 –Provided a relaxation of the OOBE limits for operation of U-NII-3 band devices –Extended the deadline for certification of U-NII-3 band devices and deadline for the manufacture, marketing, sale and importation of these devices –Declined to adopt rules that would remove restricted band protections from emissions produced by U-NII-1 band devices or would permit U-NII-1 client devices to operate with higher emissions and declined to reduce the upper UII-3 band edge from 5.85 to GHz Previous Rules 5GHz Band 21
