IEEE 802.11ac/af and Spectrum Sharing Month Year doc.: IEEE 802.11-yy/xxxxr0 July 2013 IEEE 802.11ac/af and Spectrum Sharing Date: 2009-07-16 Authors: Rich Kennedy, BlackBerry Corporation John Doe, Some Company

Month Year doc.: IEEE 802.11-yy/xxxxr0 July 2013 Abstract As the Internet of Everything (IoE) becomes a reality, IEEE 802.11af strives to create a wireless world that enables Spectrum for Everything (SfE). This presentation will describe some of the unique advantages of 802.11af technology, and how it opens up huge opportunities for networks working in license-exempt spectrum. Rich Kennedy, BlackBerry Corporation John Doe, Some Company

Introduction The technology of the devices July 2013 Introduction The technology of the devices Drawing on the advances of IEEE 802.11ac Range in the TV bands Geo-location database as an enabler The database The RLSS The Future Rich Kennedy, BlackBerry Corporation

IEEE 802.11af Radio Technology July 2013 IEEE 802.11af Radio Technology IEEE 802.11ac is designed to operate in the 5 GHz bands Tremendous capacity gains Up to 160 MHz channels for over 1 Gbps throughput Able to operate in multiple, non-contiguous channels IEEE 802.11af uses the same leading-edge technology, and scales it down for smaller channels Can operate in 6, 7 or 8 MHz channels or multiples of them to match the TV band allocations At least 5x times range advantage over 11ac, maximizing data throughput over longer range micro-cells Rich Kennedy, BlackBerry Corporation

US 5 GHz TAXONOMY March 2013 Mar 2013 July 2007 http://hraunfoss.fcc.gov/edocs_public/attachmatch/FCC-13-22A1.pdf (plain) https://mentor.ieee.org/802.18/dcn/13/18-13-0017-01-0000-fcc-5-ghz-unii-rules-revision-nprm.docm (highlights) U-NII-1 = 5150-5250 U-NII-2A = 5250-5350 U-NII-2B = 5350-5470 NEW U-NII-2C = 5470-5725 U-NII-3 = 5725-5825 (NEW Proposal to extend to 5850) U-NII-4 = 5850-5925 (NEW) Peter Ecclesine (Cisco Systems) Peter Ecclesine (Cisco Systems)

Band plan with new spectrum Importance of Additional Spectrum Wide bandwidth channels desired to support high throughput requirements At the same time, large number non-overlapping channels desired to support high QoS requirements To avoid co-channel interference Current UNII spectrum allows only Six 80 MHz channels Two 160 MHz channels Additional unlicensed use of 5.35-5.47 GHz and 5.85-5.925 GHz would allow Nine 80 MHz channels Four 160 MHz channels 144 140 136 132 128 124 120 116 112 108 104 100 165 161 157 153 149 64 60 56 52 48 44 40 36 IEEE channel # 20 MHz 40 MHz 80 MHz 160 MHz UNII-1 UNII-2 UNII-3 5250 MHz 5350 5470 5725 NEW 96 92 88 84 80 76 72 68 169 173 177 181 5825 5925 Currently available channels New channels

Channel Bandwidth Flexibility July 2013 Channel Bandwidth Flexibility Rich Kennedy, BlackBerry Corporation

Geo-location Databases July 2013 Geo-location Databases Designed to maximize the use of under-utilized spectrum For Experimental Licensed (like the US databases, where 24-hours is the standard of enablement) For localized control (campuses, large enterprises, etc.) A Registered Location Secure Server can maintain the area knowledge and be the enabler for one or more small networks Rich Kennedy, BlackBerry Corporation

July 2013 The RLSS The RLSS provides the database function for multiple networks It can access a regulatory database, or using centrally mounted antennas, provide available channel information based on sensing of the spectrum Rich Kennedy, BlackBerry Corporation

Regulatory Flexibility July 2013 Regulatory Flexibility Regulatory limits are set in Operating Classes Originally designed with the FCC in mind (because it had the only published rules at the time), the elements for operating in various regulatory domains gets coded into the Operating Classes As more regulatory domains specify their rules, it require only the specification of the appropriate classes, or creating new classes Rich Kennedy, BlackBerry Corporation

United States Operating Classes July 2013 United States Operating Classes Table E-1—Operating classes in the United States   Operating class Global operating class (see Table Table E- 4— (Global operating classes)) Channel starting frequency (GHz) Channel spacing (MHz) Channel set Channel center frequency index Behavior limits set 85 0.045 (channels 2-4), 0.049 (channels 5, 6), 0.099 (channels 7-13) or 0.389 (channels 14-51) 6 — GeoDB 86 12 87 24 NOTE—Channel starting frequency is the frequency that results in the regulatory domain's channel number being the RLAN channel number. Rich Kennedy, BlackBerry Corporation

July 2013 Some Future Examples In other bands, this technology can be used to provide interference-free spectrum access for special applications For geo-survey satellite bands, it can secure the spectrum while a satellite is scanning a region, and share it when it is not, based on the highly predictable satellite path For defense use of spectrum, eliminates the need to provide sensing data (like DFS) to maintain security of the satellite, UAV, etc. Rich Kennedy, BlackBerry Corporation
