  1. WiMax Overview Eric Jacobsen Minister of Algorithms, Intel April 21, 2005

  2. What is WiMax? • www.intel.com/go/wimax • www.intel.com/netcomms/technologies/wimax/flash/base.htm • www.wimaxforum.org • A non-profit corporation that provides compatibility and interoperability certification for broadband wireless products • Uses standards documents as the compliance references • A technology that provides wireless MAN/WAN access for fixed, mobile, and roaming users

  3. Standards and CertificationRelationships • Personal Area Networks (PAN) • 3m – 10m range – WiMedia • Related to IEEE 802.15.3a standard development – using MBOA UWB proposal • Local Area Networks (LAN) • 10m – 100m range - WiFi-Alliance (WFA) • IEEE 802.11 • Metropolitan Area Networks (MAN) • 100m – 2mi range - Wi-MAX Forum • IEEE 802.16 and ETSI HiperMAN Indicated Ranges are Approximate

  5. Wi-Fi Intel’s WiMAX Vision Mobile/ Portable Broadband High Throughput Access: Business, Backhaul & some Residential Hotspot Backhaul Consumer Broadband Access Wi-Fi Wi-Fi

  6. 1st: Outdoor Subscriber Station Wi-Fi Business Access & Backhaul 802.16-2004 Hotspot Backhaul Premium Residential Service Wi-Fi Wi-Fi

  7. Outdoor Subscriber Station802.16-2004 (formerly 802.16d) • Directional antenna • When installed, it’s aligned with base station • It’s fixed – it never moves location • Always higher throughput than omni-directional antenna • Applications • Rural / Macro-cell deployments • Wi-Fi hot spot backhaul • Premium residential, MDU connectivity • Challenging environments Wi-Fi Business Backhaul & Premium Residential

  8. Towerstream, Boston • Towerstream • Covering greater Boston & greater Providence • 12+ Cells in Service • 90% Coverage • Over 500 business customers • 5.8 GHz • Multi-tiered Business Services with SLA’s • 1 Mbps to 8 Mbps • Courtesy of Aperto Networks (2004)

  9. BCL, New Zealand Wireless DSL Coverage Base Station • Broadcast Communications Limited (BCL) Wholesale Wireless Access Network. • Nationwide deployment from 74 Base Stations Sites • Network designed for 30,000 connections initially; • Expansion to 100,000 planned. • Network covers around 100,000 sq km • 5.8 GHz spectrum • Providing High Speed links – longest distance of 50 km! • Data & Voice • Each CPE delivers 2Mbit/s Asymmetric DSL • Up to four 64 kbps TDM voice lines • Courtesy of Airspan Networks, 2004 Range: 50 km CPE

  10. Wi-Fi Wi-Fi Wi-Fi Wi-Fi Wi-Fi 2nd: Add Indoor Subscriber Station Wi-Fi Business Access & Backhaul 802.16-2004 Self Install Indoor Modem Hotspot Backhaul Consumer Broadband Access Wi-Fi

  11. Indoor Subscriber Station802.16-2004 (formerly 802.16d) • Omni-directional antenna • Designed to not require alignment with base station • May work better near a window • Optional window-mount antenna • Portable but fixed when in use • Can be moved to a different room in the house or a different location within the service area • Lower throughput than directional • Applications • Consumer DSL-like broadband • Carriers who want to avoid truck rolls • Customer self installation • Precursor for portable/mobile Integrated 802.16/802.11 Access Point

  12. Wi-Fi Wi-Fi Wi-Fi Wi-Fi Wi-Fi Wi-Fi 3rd: Add Portable Client Business Access & Backhaul 802.16e & 802.16-2004 Hotspot Backhaul Consumer Broadband Access Wi-Fi

  13. Portable Client - 802.16e PCI Express* Form Factor or Mini PCI* • Omni-directional antenna • Not aligned with base station • Location can vary • Portable to support both fixed and mobile use • Can be moving while in use • Lower throughput than directional antenna • Lower throughput than omni-directional (Indoor Fixed) • Applications • Consumer DSL-like connectivity in the wider area network Laptop Seeks Best Connection: 802.11 if in vicinity of Hot Spot 802.16 if outside Hot Spot range

  14. WiFi WiMAX and Wi-Fi in the Laptop WiMAX Carrier Broadband Wireless Netvigator Wireless Hotspot 802.16 WiMAX Broadband Wireless Netvigator Wireless Hotspot My Home (Connected) Wi-Fi WiMAX Hub CS • Laptop Add-In Card Target Features: • PCI Express* Form Factor w/ Simplified Network Connection software • Integrated Lid Antenna
