Pace of Advancing Technology

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)

• 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
• Forward Auction
• Concluded February 10, 2017
• $19.6 Billion in proceeds
• Assignment round began March 6, 2017
• Auction closing and channel reassignment PN will begin 39 month transition period

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

Technical Pillars of the Incentive Auction

Adopted final rules in 2012

• Fixed & Personal Portable devices
• Rely on geolocation database

Fifteen devices approved

• 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

Rules updated August 2015

• Implement Incentive Auction
• More flexible operation

NPRM adopted December 2015

• Require geo-location capability in fixed devices
• Validation checks for databases

Unlicensed White Space Devices

The 5 GHz Band & Unlicensed Use

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.

• 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

in communications infrastructure.

• 7. Cities and stadiums get major Wi-Fi upgrades.

More than 3 billion Wi-Fi device shipments expected in 2017 and more than 8 billion devices currently in use around the world.

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

• 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 sharing across three tiers

3.5 GHz: Citizens Broadband Radio Service

• 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

Spectrum Frontiers & 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

• High amount of spectrum

provides flexibility to avoid interference

• Relatively high path loss
• Adaptive antenna technology

(steered beams)

• Heterogeneous networks

Full Dimensional MIMO 5G Deployment Scenario

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
