1 Regulatory Perspectives on 5G Chris Helzer Chief Engineer, WTB, FCC June 9, 2015

2 Overview Key principles Technology neutrality, regulatory flexibility, time to market Observations on 5G Its multifarious nature Spectrum outlook Recent spectrum initiatives Spectrum frontiers / millimeter wave Millimeter wave notice of inquiry (NOI) Bands, technologies, licensing models Next steps 1

3 Key Principles Technology neutrality Do not specify technologies for bands Let industry and the market find the best use of the spectrum Regulatory flexibility Flexible use Requirements focus on in-band and out-of-band power levels Do not exclude particular technologies Time to market Example: LTE in 700 MHz 700 MHz auctioned with flexible technical rules Allowed providers to build nationwide coverage quickly and without refarming other bands US lead in LTE deployment 2

4 Observations on 5G Multiple performance metrics Not just peak rates Low latency and high latency applications Low throughput and high throughput applications Multiple levels of integration Multiple bands carrier aggregation plus Multiple topologies heterogeneous networks plus Many ideas, much marketing Many possible paths Evolution of LTE? Evolution of Wi-Fi? Something else? Still early days of defining 5G 3

5 Spectrum Outlook Existing flexible use bands Recent spectrum initiatives WCS R&O 20 MHz AWS-4 R&O 40 MHz H block auction 10 MHz AWS-3 auction 65 MHz 3.5 GHz R&O 150 MHz 600 MHz incentive auction next year Future millimeter wave bands Technological Advisory Council (TAC) recommendation to study millimeter wave spectrum Notice of Inquiry (NOI) in October 2014 Received comments from multiple industries and academia, 66 comments and reply comments 4

6 Spectrum Frontiers NOI Explores a number of bands above 24 GHz, asking questions in three areas What bands? Physical properties Existing uses What licensing models? Licensed Unlicensed Innovative hybrids What technical rules? Maintain flexibility for antenna arrays, massive MIMO, etc. 5

7 NOI Technologies Technology Smart Antennas Bandwidth Key Performance Indicators Backhaul Deployment Scenarios Representative Comments Multi-element base station antennas (32, 64 elements, patch antennas) Multi-element device antennas (modular arrays of 4 elements or more) Digital, analog, and hybrid beam forming and MIMO processing of array(s) Modules including an RFIC chip and beam forming unit Throughput is a function of available bandwidth Large contiguous blocks of spectrum present certain advantages over multiband spectrum aggregation, particularly with respect to devices Interest in contiguous blocks of 500 MHz- 2 GHz Throughput up to 10 Gbps and at least 100 Mbps at cell edge End-to-end latency of < 5 milliseconds and air latency of < 1 millisecond Channel bandwidths in excess of 1-2 GHz Integrated backhaul and access (multi-hop communication) In-band and out-of-band options in the mmw bands Fiber and other options Complementary / limited area deployment? Ubiquitous coverage? 6

8 NOI Frequency Bands Band 24 GHz LMDS 37/42 GHz 39 GHz 60 GHz 70/80 GHz Comments No mobile allocation Two band segments, GHz and GHz Licensed in geographic areas to fixed services Co-primary for fixed and mobile Thee band segments, GHz, GHz, and GHz Licensed on geographical basis FSS sharing possible Co-primary for fixed and mobile (but not authorized for mobile) Large contiguous bands (1.6 GHz) and (0.5 GHz) Larger contiguous block possible by combining with 39 GHz band Federal use Co-primary for fixed and mobile Large contiguous bands (1.4 GHz) Licensed by Economic Area Co-primary for fixed and mobile Large contiguous bands (7 GHz) and (7 GHz) Unlicensed operation in the GHz band (IEEE ad) Co-primary for fixed and mobile Large contiguous bands (5 GHz) and (5 GHz) Non-exclusive licensed operation, database aided spectrum coordination 7

9 Next Steps Rollout of 3.5 GHz 600 MHz incentive auction Continuing process on millimeter wave bands 8
