Strategy of Making More Spectrum Available • Driver: Continued growth of mobile & other services • Key Milestones: • National Broadband Plan • Middle Class Tax Relief & Jobs Creation Act of 2012 • Presidential Memos • NTIA Ten Year Plan • PCAST Report • Department of Defense Spectrum Strategy • Strategy: • Consider potential reallocations, but becoming more difficult • Develop advanced spectrum sharing techniques • Continue to advance efficient use of the spectrum (flexibility)

Broadcast TV Incentive Auction How it Works • Reverse Auction • Ended January 13, 2017 – Stage 4; 84 MHz clearing target • Broadcaster clearing cost - ~ $10 Billion • Broadcaster relocation funds – $1.75 Billion • ~ $12 Billion needed to cover costs Paired Spectrum Blocks Repurposed 7 84 21 22 23 24 27 25 26 27 28 29 30 31 32 33 34 35 36 37 3 11 700 MHz UL A B C D E F G A B C D E F G • Forward Auction Licensed Unlicensed Mics Microphones 1 MHz buffer • Concluded February 10, 2017 Downlink Uplink • 6 $19.6 Billion in proceeds megahertz • Assignment round began March 6, 2017 WSD 11 Megahertz “Duplex Gap” • Auction closing and channel reassignment PN will begin 39 month transition period

Technical Pillars of the Incentive Auction Can’t assign OK to assign same channel same channel – too close – far apart TV Study: Constraints on Software Used to predict Repacking Stations Coverage & Population Served Reorganize remaining stations in most efficient way that recovers the most spectrum at the least cost - - akin to repacking the closet Repacking Optimization ISIX: Controlling Interservice Interference

Unlicensed White Space Devices Adopted final rules in 2012 • Fixed & Personal Portable devices • Rely on geolocation database Fifteen devices approved Meld Carlson Adaptrum • All fixed devices, designed for professional installation - location entered manually Five databases approved IEEE 802.11af standard approved - Dec. 2013 Strong international interest • Pilots in Philippines, South Africa, Namibia, Botswana and many others Spectrum iconectiv Rules updated August 2015 Bridge • Implement Incentive Auction • More flexible operation NPRM adopted December 2015 • Require geo-location capability in fixed devices • Validation checks for databases Wireless Cameras Cover Park in Wilmington NC 8

The 5 GHz Band & Unlicensed Use More than 3 billion Wi-Fi device shipments expected in 2017 and more than 8 billion devices currently in use around the world. Wi-Fi Applications Wi- Fi Alliance: 7 for ’17 predictions: 1. Wi-Fi simplifies wireless networking. 2. High-performance Wi-Fi products with new features and technologies will hit the shelves. Offloading 3. Wi-Fi Location will gain momentum. 4. Wi-Fi is a platform for IoT innovation. 5. Wi-Fi improves the AR/VR experience for the masses. 6. Wi-Fi cements its place as a critical component Video Streaming in communications infrastructure. Around Home IoT 7. Cities and stadiums get major Wi-Fi upgrades. And many, many more . . .

5 GHz Background • Middle Class Tax Relief & Jobs Creation Act of 2012: • NTIA to study two bands at 5 GHz for unlicensed • 5350 – 5470 MHz: allocated for federal (radars) & earth exploration satellites • 5850 – 5925 MHz: allocated for non-federal use (Intelligent Transportation Services) • FCC to initiate rule making • NTIA study (Jan. 2013): More study needed • FCC initiates rule making (Feb. 2013) • IEEE Tiger Team Studies 5.9 GHz sharing (August 2013 – March 2015): • Two lead proposals considered • Unable to achieve consensus on 5.9 GHz sharing

Expanding Unlicensed Spectrum Use in 5 GHz Previous Rules A l l o c a t i o n s U n l i c e n s Now 250 mW e d • Much of the 5 GHz band is shared by unlicensed on a non-interference basis • Some of this spectrum relies on dynamic frequency selection to avoid interfere with radars • FCC Notice of Proposed Rule Making • Proposed access to U-NII-2B and U-NII-4 for unlicensed • Invited comment on possible sharing techniques • No change to existing spectrum allocations - - existing allocations/services are protected against harmful interference

IEEE Tiger Team Options Dedicated Short Range Communications (DSRC) Channel Plan • Option 1 Detect and avoid (Cisco): Unlicensed devices monitor the 10 megahertz-wide DSRC channels and vacate entire band if signal detected • Option 2 Rechannelization (Qualcomm) : safety channels to top of the band, widen lower channels & share only lower channels with Wi-Fi

Recent FCC Action on 5 GHz • FCC Public Notice (June 2016) • Refresh the record • Invite comments on two options • Invitation to submit prototype devices • Outlined Three Phase Test Plan with DOT & NTIA • Phase I - FCC Lab • Phase II - DOT Basic Field Tests • Phase III - Real-world Testing • Provided draft test plan • FCC has received several prototypes and is currently testing them at the FCC lab in Columbia, MD • Currently analyzing data and performing further test

Spectrum Frontiers & 5G • Core Principles of FCC Approach • Identify substantial spectrum in MMW bands for new services • Protect incumbent services against interference • Flexible use: Enable market to determine highest valued use • Overlay auctions where no existing assignments • Provide spectrum for both licensed and unlicensed use • Added 10.85 GHz of for mobile service • Licensed: (3.85GHz): 27.5-28.35 GHz; 38.6-40 GHz; 37-38.6 GHz • Unlicensed: (7GHz): 64-71 GHz • Adopted licensing, operating & technical rules • Considering add’l 15.8 GHz + above 95 GHz – 24.25-24.45 GHz; 24.75-25.25 GHz; 31.8-33.4 GHz; 42-42.5 GHz; 47.2-50.2 GHz; 71-76 GHz; 81-86 GHz; bands above 95 GHz

What is 5G? • Components of 5G are being identified and under discussion/development • Throughput (>50x of 4G, or 5-10GBps) and latency (<1msec air latency) are often discussed • The overall network architecture and end-user experience are being developed

Factors to Enable Sharing Full Dimensional MIMO • High amount of spectrum provides flexibility to avoid interference • Relatively high path loss • Adaptive antenna technology (steered beams) 5G Deployment Scenario • Heterogeneous networks

Recent Activity and Next Steps • Strong support for FCC order • Suppliers have developed equipment • Carriers are conducting tests & planning trials • Consider comments on Further NPRM • Experimental licensing: Greater Flexibility • Advanced Wireless Research Initiative: • $400 million initiative led by the National Science Foundation (NSF) to enable deployment and use of four city-scale testing platforms for advanced wireless research over next decade • For details see https://nsf.gov/cise/advancedwireless/
