    • Wireless USB…! and a few other! PAN Technologies! Mike Coop! heyCoop, LLC! mcoop (at) heycoop.com! © 2009 heyCoop, LLC All rights reserved
    • Obligatory Disclaimer Slide! •  Don’t believe anything I say! •  Use this presentation to facilitate your research, not in lieu of! •  Opinions expressed are solely my own, and represent no entity other than heyCoop, LLC! © 2009 heyCoop, LLC All rights reserved
    • Obligatory Who Am I Slide! •  20+ years in technology, in roles including systems engineering, business development, sales, and marketing! •  Tenure in organizations large (Microsoft, Cisco) and small (Cranite Systems, Tzero Technologies)! •  Spent 2002-2006 as VP of Consulting Engineering at Cranite, working through various wireless policies, including ASD-NII, Army, Navy, and Marine Corps! •  Spent 2006-2007 as VP of Strategic Alliances at Tzero, working on ultra-wideband PAN standards and implementation! •  Launched heyCoop, LLC in 2007, focusing primarily on consumer electronics and digital home standards and implementation—and on information assurance policy! •  In addition to customer work, heyCoop, LLC is a member of IEEE 1680.3, UPnP Forum, and Bluetooth SIG! © 2009 heyCoop, LLC All rights reserved
    • Topics! •  Data-centric wireless PAN technologies! –  Certified Wireless USB! –  Bluetooth! –  Cliffside! •  SuperSpeed USB (one slide, just because)! •  Video-centric wireless PAN technologies! –  WHDI! –  Wireless HD! –  WiGig! © 2009 heyCoop, LLC All rights reserved
    • What is Certified Wireless USB?! •  Does what you think it does—allows USB connectivity, wirelessly! •  More than 100 certified devices; mostly silicon, but numerous hub & dongle sets, laptops, docking stations, and other device categories! •  Top speed of 480 mb/s; uses 528 MHz channels in the 3.1-10.6 GHz bands! •  Based on an ultra-wideband specification originally published by WiMedia Alliance! © 2009 heyCoop, LLC All rights reserved
    • What is Ultra-wideband?! •  Ultra-wideband (UWB) is a wireless transmission technique approved for unlicensed use in 2002 under FCC Part 15 ! •  As defined by the FCC and ITU, UWB is a transmission whose bandwidth is either! –  20% of its center frequency! –  At least 500 MHz wide! © 2009 heyCoop, LLC All rights reserved
    • Where is Ultra-wideband?! © 2009 heyCoop, LLC All rights reserved
    • How is Ultra-wideband?! •  Good news! –  Wicked amounts of bandwidth! –  Security baked in from the start! –  Second generation products now shipping! •  Bad news! Horrible restrictions on emitted power! –  First generation products kind of sucked! –  Still too pricey compared to Wi-Fi and Bluetooth! –  Industry alliance has shuttered, leaving further –  development in doubt! © 2009 heyCoop, LLC All rights reserved
    • Wireless USB Security! •  Initial setup is called “association”! –  Cable model mandates a first connection via cable; once associated, devices can communicate wirelessly! –  Numeric model mandates comparison of codes displayed on both devices, or manual entry of a displayed code (similar to Bluetooth)! •  Well-designed security architecture! Mutual authentication! –  4-way handshake! –  Pairwise temporal key (PTK)! –  Group temporal key (GTK)! –  •  Data privacy uses CCM—Counter with CBC-MAC! •  Integrity is a 64-bit MIC for entire packet! •  Much more on wireless USB security at http://tinyurl.com/wusbsecurity! © 2009 heyCoop, LLC All rights reserved
    • Wireless USB’s Future! •  Should you care?! •  Yes and no! •  While possible to have CW-USB products go through FIPS (due to CCM-based architecture), it’s unlikely! •  Disbanding of WiMedia Alliance, and assignment of core intellectual property to USB-IF and Bluetooth SIG make further concerted development unlikely! •  HOWEVER, head-in-sand approach to CW-USB would risk a repeat of other agencies’ hiccups with policies on Wi-Fi, Bluetooth, and other technologies! –  USN/USMC has typically led the way on wireless policy! –  Today, CW-USB looks like a dying technology, based on high prices, low throughput rates, and significant competition! –  Pundits once claimed Wi-Fi, Bluetooth, and Ethernet to be dead technologies, too! © 2009 heyCoop, LLC All rights reserved
    • Bluetooth 3.0 + HS! •  Adopted in April 2009! •  Includes 802.11 protocol adaptation layer as an Alternate MAC/PHY (AMP)! –  Wi-Fi Alliance performed an enormous amount of work to win inclusion in Bluetooth 3.0! –  WiMedia UWB was originally the AMP for 3.0, and could still see the light of day! •  Supports data transfer speeds up to 24 mb/s! •  Products expected in early 2010! © 2009 heyCoop, LLC All rights reserved
    • Cliffside! •  Cliffside was the code name for Intel’s My WiFi technology! •  Uses “split-MAC” technology to enable simultaneous infrastructure (connection to AP for backhaul) and peer- to-peer (PAN) modes! •  Enables connection of up to eight devices without an AP or router! •  Provides 802.11i support on both AP and PAN links! •  Has the potential to be very interesting! •  Much more on Cliffside at http://tinyurl.com/coopcliff! © 2009 heyCoop, LLC All rights reserved
    • SuperSpeed USB (USB 3.0)! •  10x performance of USB 2.0 (4.8 gb/s versus 480 mb/s) —key for flash-based products! •  Provides backwards…! –  Performance compatibility with 2.0 devices (at 2.0 speeds)! –  Connectivity capability, both electrically and physically! –  Driver support—things just work! •  Cables and connectors! –  Standard A cables backwards compatible with 2.0! –  New B and Micro AB receptacles backwards compatible with 2.0! Better power efficiency than 2.0! •  Devices beginning to arrive! •  Requires separate software drivers currently! •  OS integration to appear in follow-on to Windows 7 •  launch! © 2009 heyCoop, LLC All rights reserved
    • Wireless video approach based on 20 and 40 MHz channels in •  the unlicensed 5 GHz band! Promoter members include Amimon, Hitachi, LG, Motorola, •  Samsung, Sharp, Sony! Claims! •  30 meter range! –  Through-wall operation! –  <1 ms latency! –  “No compression”! –  Link security addressed via use of HDCP! •  Best known product at this point is Sony’s wireless video •  extender! Concern that as more 802.11n high-band (5 GHz) devices •  enter homes, performance will suffer! Amimon began shipping pre-standard chipsets in April, 2008; •  standard (interoperable) products expected imminently! © 2009 heyCoop, LLC All rights reserved
    • •  Wireless video approach based on 2.5 GHz channels in the 60 GHz band! •  Promoter members include Broadcom, Intel, LG, Panasonic, Philips, NEC, Samsung, SiBEAM, Sony, Toshiba! •  Claims! 10 meter range! –  In-room operation! –  <1 ms latency! –  No compression! –  •  Link security addressed via use of HDCP! •  Few interference concerns! •  SiBEAM began shipping pre-standard chipsets in fall, 2008; standard (interoperable) products expected imminently! © 2009 heyCoop, LLC All rights reserved
    • Wireless video and data networking approach based on 60 •  GHz transmission ! Board members include Atheros, Broadcom, Dell, Intel, LG, •  Marvell, MediaTek, Microsoft, NEC, Nokia, Panasonic, Samsung, Wilocity! Claims! •  Initial specifications to become available in late 2009! –  Connectivity of up to 6 gb/s! –  Will address not just wireless video, but mobile and CE devices! –  Envision a dual-mode architecture, with Wi-Fi capabilities at 2.4/5 –  GHz and WiGig capabilities at 60 GHz! Link security will need to be addressed via use of HDCP for •  video; likely to use variant of WPS/802.11i! If specifications arrive in early 2010, and C&I is defined later •  in 2010, the market might see products by CES 2011! Might! •  © 2009 heyCoop, LLC All rights reserved
