Lessons Learned Coordination among database providers is critical Required development of a complex data exchange protocol to ensure that the information is updated frequently and consistently; Need for the device authentication protocols to register and authenticate devices by the database provider currently, at the time of certification devices are approved for communications with specific database providers Ensure consistent method of calculating protected areas each database must provide the same answer Need a process for authenticating user input and for ensuring data integrity Need clear policy for handling license database errors Clarify handling of expired licenses w/ pending renewals Once issues discovered, need effective way to quickly communicate remedies to all databases Out of band emissions can be a challenge 2014 Dynamic Spectrum Alliance 8

Proposed Rule Changes (Accommodate Incentive Auction) NPRM adopted Sept. 30, 2104 Proposed unlicensed operation in: Remaining white space Duplex gap Guard bands Channel 37 Shared non IX to medical telemetry and radio astronomy Recovered spectrum until wireless operation commences Proposed additional technical flexibility for devices = Bands proposed for unlicensed 9

Spectrum Sharing: Small Cells @ 3.5 GHz 10

Citizens Broadband Radio Service Report & Order Adopted April 17, 2015 Citizens Broadband Radio Service Federal Navy Ship Radars Non-Federal FSS ES Federal Ground-Based Radar 3550 3600 3650 3700 FSS 150 MHz of contiguous spectrum Dynamic spectrum access for small cells 11

Three Tier Access Incumbent Access Priority Access General Authorized Access Incumbent Access: Includes authorized federal and grandfathered Fixed Satellite Service (FSS) users currently operating in the 3.5 GHz Band. Priority Access License (PAL): Authorize certain users to operate with some interference protection in portions of the 3.5 GHz Band at specific locations General Authorized Access (GAA): Users authorized to use the 3.5 GHz Band opportunistically. GAA users required to accept interference from Incumbent and Priority Access tier users. 12

License Areas PALs licensed by census tract Over 74,000 census tracts in U.S. May aggregate census tracts U.S. Census Tracts Washington DC 2014 Dynamic Spectrum Alliance 13

Protected Access vs General Authorized Access Band wide Operability Requirement All Citizens Broadband Service Devices (CBSDs) must be capable of two way transmission on any frequency from 3550 3700 MHz Citizens Broadband Radio Service Navy Ship Radars Non-Federal FSS ES Federal Federal Ground-Based Radar 3550 3600 3650 3700 FSS Shared Between PALs and GAA Protected Access Licenses Up to seven 10 megahertz licenses Can aggregate up to four PALs in any census tract Assigned through auction Three year term General Authorized Access Opportunistic use General Authorized Access Only Increased technical flexibility Additional power in rural areas Existing equipment exempt from band wide operability requirement 2014 Dynamic Spectrum Alliance 14

Incumbent Protection Protection of Federal Systems at 3550 3650 MHz Phase 1 Exclusion zone near coastlines Phase 2 Environmental sensing capability Exclusion zone protection zone Protection of Non Federal Systems at 3650 3700 MHz Incumbent terrestrial broadband licensees grandfathered for five+ years Grandfathered FSS (3600 3700 MHz) register with FCC yearly Protection based on operating parameters Further Notice explores additional protection criteria Proposed exclusion zone Adopted exclusion / protection zone Three Federal radar sites protected via 80 km exclusion zone. 2014 Dynamic Spectrum Alliance 15

Spectrum Access System (SAS) A next generation sharing system building on white spaces Determine available frequencies at a location and assign them to CBSDs Determine maximum permissible power level for CBSDs at a location Register and authenticate CBSDs Enforce Exclusion and Protection Zones Protect PALs from IX from other users SAS Functions Facilitate coordination between GAAs Ensure secure and reliable transmission of information between the SAS, ESC, and CBSDs Protect Grandfathered Wireless Broadband Licensees Facilitate coordination and information exchange between SASs 16

More Work To Do Further Notice of Proposed Rulemaking Defining Use of PAL frequencies Implementing secondary markets in Priority Access Licenses Optimizing Protection for FSS In band protection of FSS in 3600 3700 MHz Out of band protection of C band FSS earth stations SAS Provider selection and authorization Will use process similar to TV White Spaces Multi stakeholder process FCC appreciates industry establishing a multi stakeholder process Regulations set framework Industry collaboration will be key to successful implementation 17

Spectrum Sharing: Unlicensed at 5 GHz 18

Expanding Spectrum for Unlicensed at 5 GHz Previous Rules 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 19

Implications for Wi Fi Current 802.11ac and Potential New Usable Channels 20

Ongoing Work U NII 2B (120 Megahertz) 5350 5470 MHz Sharing with federal plane/ship/terrestrial radars & earth exploration satellite US proposing to continue international work for WRC 19 Moving forward domestically Work group established: FCC/NTIA/DoD/NASA Considering IX protection studies & developing ways to share Evaluating sharing with indoor low power/then outdoor high power U NII 4 (75 Megahertz) 5850 5925 MHz Sharing with Dedicated Short Range Communications Vehicle to Vehicle Vehicle to Infrastructure IEEE Tiger Team has been working on industry proposals FCC/NTIA/DoT collaborating Considerations: Protect safety of life Roads are everywhere Wi Fi & DSRC are similar 21

Model City Program 22

Model City Program NTIA/FCC Model City Program for Demonstrating and Evaluating Advanced Wireless Spectrum Sharing Technologies Outgrowth of Report from President s Council of Advisors on Science and Technology (PCAST) April 15 16 workshop explored concept, scope, governance, process, technical considerations and funding alternatives. Some trade-offs to Consider Urban Area: A Real Test but high risk Remote Area: More limited demonstration but low risk 23

Other Sharing Matters Proceeding on Globalstar s proposed Terrestrial Low Power Service (TLPS) Development of LTE U initially planned for upper 5 GHz unlicensed band http://www.3gpp.org/newsevents/3gpp news/1660 laa_ieee 24

The Future? Autonomous devices that rely on sensing to access spectrum Issues What signal level to sense for How to measure Hidden node problem Spectrum policy Enforcement Potential solutions Common sensor networks Collaboration between devices Multiple antennas / Smart antennas New adaptive waveforms Adaptive propagation models Geographic / Topographic models I DO WHAT I WANT (As long as it doesn t cause harmful interference) 2014 Dynamic Spectrum Alliance 25

How Do We Get There: Research and Development NTIA: Center for Advanced Communications / National Advanced Spectrum and Communications Test Network National Information Technology R&D (NITRD)/ Wireless Spectrum R&D (WSRD) coordinate spectrum related research and development activities across the Federal government. Has held seven workshops on various aspects of spectrum sharing National Science Foundation Enhanced Access to Radio Spectrum (EARS) Defense Applied Research and Development Program: Radars The Department of Defense (DOD) Established a Section 845 Other Transaction (OTA) agreement to develop and mature technologies and support policy development to enable advanced approaches to spectrum use Academic Work Dynamic Spectrum Access Networks (DySpan) International Symposium on Advanced Radio Technologies (ISART) And YOU! 26
