Spectrum Management Activities at the FCC’s Office of Engineering and Technology Note: The views expressed in this presentation are those of the author and may not necessarily represent the views of the Federal Communications Commission Julius Knapp, Chief Office of Engineering and Technology National Spectrum Management Association May 16, 2012

2. Chairman’s Mobile Action Plan (Spectrum Components) 1. Core Opportunities • Removing barriers • Auction 65 MHz • Expand 5 GHz Wi-Fi 2. New Tools • Incentive Auctions • White Spaces 3. Next Frontiers • Sharing • Small Cells • Receivers • Build on strong foundations (Spectrum Act, National Broadband Plan, President’s Executive Memo) • Near-term actions for all three tracks

3. TV White Space:What We’ve Done Jan. 26, 2011, the Commission’s Office of Engineering and Technology issued an Order in ET Docket 04-186, DA 11-131 that conditionally designated TVWS Data Base Administrators: Comsearch, Frequency Finder Inc., Google Inc., KB Enterprises LLC and LS Telcom, Key Bridge Global LLC, Neustar Inc., Spectrum Bridge Inc., Telcordia Technologies, and WSdb; later added Microsoft March – May 2011 held 3 public workshops plus additional meetings & dialogue; Extensive info at: http://transition.fcc.gov/oet/whitespace/ Sept. 14, 2011: Announced 1st TVWS data base test - Spectrum Bridge Dec. 2, 2011: Announced 2nd TVWS data base test - Telcordia Dec. 22, 2011: Approved first data base administrator - Spectrum Bridge Dec. 22, 2011: Approved first TVWS device – Koos Technical Services, Inc. (KTS) Jan. 26, 2012: First commercial deployment - Wilmington, NC March 26, 2012: Approved second data base administrator – Telcordia April 19, 2012: Approved second device – Adaptrum; authorized deployment in Nottaway, VA

4. TV White Space:What We Are Doing Accepting & processing applications for equipment certification Continuing process to approve data base administrators Establishing wireless microphone registration process Waivers to register certain TV receive sites in data base

5. Benefits of TV White Space • Prime spectrum • Great propagation & coverage • High amounts in much of the USA • Close to spectrum used by commercial wireless services - - potential synergy • New IEEE 802.22™ standard: • IEEE SA Emerging Technology of the Year Award • Broadband wireless access over a large area up to 100 km • Up to 29 Mbps per TV channel • Can increase data rate through use of multiple channels • Wi-Fi & TV White Space is not an either-or proposition: • Each may suit particular needs • Wi-Fi has greater bandwidth but usage density is increasing • When combined consumers & users could see significant benefits

6. Potential Applications Provides a new opportunity for innovation and delivery of service, with potential for both research and commercial applications Spectrum is open to everyone & and is available now Potential uses limited only by the imagination • Broadband (generally) • Rural broadband • Video – Monitoring, surveillance, distribution • State & Local Governments • M2M • Smart Grid • Health Care • Education • Data traffic off-load

7. TV Broadcast Incentive Auctions Middle Class Tax Relief and Job Creation Act of 2012 (Spectrum Act) provides for TV incentive auction Incentive auction would share auction proceeds with the current occupant to motivate voluntary relocation of incumbents Broadcaster participation in incentive auction is voluntary In exchange for a share of auction proceeds a broadcaster could: Contribute one or more 6 MHz channels Choose to move from U to V Share a channel with another broadcaster Or choose not to participate FCC actions: Formed Incentive Auctions Task force – Co-chairs Ruth Milkman and Gary Epstein Order on channel sharing adopted at April 27 agenda meeting Notice of proposed rule making planned by this fall

8. The FCC Would Need to Realign the Spectrum After the Auction FCC would realign the spectrum into blocks to maximize efficiency and value Without realignment, interference between television and wireless operations would increase The FCC would work with industry to minimize any interference or coverage impacts of realignment, as we did for the DTV transition Stations keep current channel numbers Moves to a lower band would be voluntary based on broadcaster reserve price Spectrum Act provides funding to relocate operations in TV channel 37 if necessary Adjacent Channel Interference TV TV TV BB TV BB Without Realignment: Reduced Broadband Bandwidth Adjacent Channel Interference BB TV TV TV TV 84 MHz With Realignment: Accommodates Increased Broadband Bandwidth 14 37 51 470 MHz 608 MHz 614 MHz 698 MHz

9. Impact on TV White Space FCC will need to create band plan Spectrum Act: FCC may implement band plans with guard bands Guard bands shall be no larger than is technically reasonable to prevent harmful interference between licensed services outside the guard bands May permit use of guard bands for unlicensed Unlicensed use shall rely on a data base or subsequent methodology as determined by the Commission Benefit - - contiguous band available everywhere There will be white space – size of guard bands & remaining TVWS TBD through rule making

10. Sharing with Radars at 5 GHz:Ix Issues & Spectrum Expansion • Sharing based on Dynamic Frequency Selection (DFS) • Devices “listen” and perform processing to detect radars • Spectrum Act requires study of expanded unlicensed @ 5 GHz • Related to IEEE 802.11ac standard under development Device detects radar and moves to an unoccupied channel 50 mW Indoor Use Only 250 mW 250 mW 1 W DFS DFS Spectrum Act: Study w/in 8 mos. for indoor use Spectrum Act: Study 5825 – 5950 MHz w/in 18 months Existing Existing Recent Expansion Existing 5825 5250 5350 5470 5725 5150 Frequency (MHz)

11. NTIA Report on 1755 – 1850 MHz NTIA recently released report on potential for reallocation of federal spectrum at 1755 – 1850 MHz for wireless broadband Numerous challenges - - cost, complexity, time Strong support for increased sharing T-Mobile recently filed for an experimental license on behalf of CTIA to perform sharing tests NTIA to convene work group under Commerce Spectrum Management Advisory Committee FCC will participate in work group • 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

12. Small Cells at 3550 – 3650 MHz • Small cells can reduce traffic on wide-area networks - provide coverage and capacity where needed • Example: Wi-Fi offload • Today, re-connect at each AP • Soon, seamless connectivity • FCC Technological Advisory Council recommended federal fast-track band 3550 – 3650 MHz for small cells • This band had little interest for wide-area networks due to high frequency & exclusion zones • Several approaches are possible for small cells and other uses in this spectrum • Proceeding later this year

13. MSS S-Band Proposal • Notice of Proposed Rule Making - March 2012 • Proposes to relax rules to facilitate increased terrestrial use of S-band MSS spectrum at 2000 – 2020 MHz (Earth-to-space) and 2180 – 2200 MHz (space-to-Earth) • Notice of Inquiry invites comment on potential band realignment to create opportunities to expand PCS • Comments due this Thursday • Figure 1: Existing 2 GHz Band Plan • Figure 2: Proposed AWS-4 Band Plan

14. Receiver Performance • Increasing focus on receiver performance as limiter to spectrum access & efficiency • FCC conducted workshop on March 12 – 13, 2012 • Various policy approaches suggested • FCC Technological Advisory Council (TAC) is studying the issue looking towards making FCC recommendations

15. Medical Body Area Networks (MBANS) • MBANS are very short-range networks consisting of multiple body-worn sensors (eg, on a patient’s chest, back, arms, etc.) and a nearby hub station: • Sensors take readings of key patient-specific information (eg, temperature, pulse, blood glucose level, etc.) • Antennas embedded in sensors make it possible to wirelessly transmit data to body-worn or closely located hub devices • Hub devices may process data locally and/or transmit it wirelessly for centralized processing, display, and storage • MBANS can reduce infection risk, increase patient mobility & improve caregiver effectiveness • FCC issued Notice of Proposed Rule Making for MBANS to share 2360 – 2400 MHz w aeronautical telemetry • Industry has submitted jointly agreed proposed rules • FCC plans to consider at May 24, 2012 agenda meeting

16. Experimental Licensing Notice of Proposed Rule Making(ET Docket No. 10-236) • Notice of Proposed Rule Making (NPRM) seeks to promote research and development of new radio technologies, devices, and applications. • Proposed to create a new type of Program License, which would give qualified entities broad authority to conduct a program of research without the need for approval of each experiment. • Proposed three types of Program Licenses: • Research license would allow universities, laboratories, and other qualified research institutions to conduct experiments over a wide variety of frequencies and other operating parameters, without the need for individual authorization or reauthorization for each individual experiment. • Geographic “innovation zones” – generally relatively remote locations - where researchers could conduct a wide range of experiments under certain general conditions. • Medical institutions to innovate and develop new devices that can save lives, have a significant impact on reducing medical costs, and provide new treatment options for our wounded service men and women. • Proposed ways to streamline and clarify the existing rules such as expanding opportunities for researchers and manufacturers to conduct market trials 16

17. FCC Notice of Inquiry on Dynamic Spectrum Access (ET Docket 10-237) Notice of Inquiry (NOI) considers how dynamic access radios and techniques can provide a more intensive and efficient use of spectrum Seeks comment on the current state of the art and how FCC can promote these technologies - - test-beds or modifying its spectrum management practices and policies Covers both licensed services and unlicensed devices What spectrum bands would be most suitable? Asks whether TV White Space model might be used for other bands Asks whether and how to incorporate spectrum sensing for other bands Asks whether FCC provisions for secondary market arrangements could be enhanced to increase use by dynamic access radios Asks how to improve FCC “Spectrum Dashboard” for DSA 17
