  1. IEEE 802.11ac/af and Spectrum Sharing Authors: Date: 2009-07-16 Rich Kennedy, BlackBerry Corporation

  2. 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

  3. 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

  4. 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

  5. US 5 GHz TAXONOMY • 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)

  6. 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 Currently available channels New channels 36 40 44 48 52 56 60 64 68 72 76 80 84 88 92 96 100 104 108 112 116 120 124 128 132 136 140 144 149 153 157 161 165 169 173 177 181 IEEE channel # 20 MHz 40 MHz 80 MHz 160 MHz UNII-1 UNII-2 NEW UNII-2 UNII-3 NEW 5250 MHz 5350 MHz 5470 MHz 5725 MHz 5825 MHz 5925 MHz

  7. Channel Bandwidth Flexibility Rich Kennedy, BlackBerry Corporation

  8. 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

  9. 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

  10. 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

  11. United States Operating Classes Table E-1—Operating classes in the United States 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

  12. 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
