  1. Multi-Use Mesh Networks Ben Moebes - ben.moebes@tropos.com June 2007

  2. Agenda • What is a Mesh Network? • What is Multi-Use • How can you increase Revenue? • Examples • BT • Houston, TX • Mesh/WiMAX integration • Q&A

  3. WiMAX Wi-Fi/WiMAX Wi-Fi/WiMAX Open Standard Radio Mesh Today/Tomorrow Wired IP Network Backhaul Ethernet to Fiber Ring T-1/E-1 Metro-Scale Mesh Routers asWired Gateways DSL Metro Scale MeshRouters Clients Mesh Architecture makes BWA ROI successful

  4. Why Tropos Mesh? Wi-Fi Device Explosion 11Mbps 54Mbps Source: IDC 250M+ Wi-Fi Client Devices Source: Instat Projected 160M+ Cellular Phones with Wi-Fi Source: IDC 150K+ Wi-Fi Hot Spots

  5. Open Standard Progression Wi-Fi Open-standards moving into wireless MAN + WAN Mesh Takes Wi-Fi to “Island” Scale • Wi-Fi originally designed as a wireless extension for indoor LANs • Mesh makes Wi-Fi effective outdoors over large areas WiMAX Wi-Fi Speed UWB 3G/UMTS 2G PAN LAN MAN WAN

  6. Web 1.0 to Web 2.0 Transition in Force Web 2.0 (Interaction) Web 1.0 (Access) • Symmetrical, true broadband links • Local content generation (photos, videos, music…) • Gaming • Uniform coverage • Users expect consistent service and experience • Indoor AND Outdoor coverage • Same devices and service regardless of location • Support existing and future devices • Wi-Fi devices are ubiquitous today • WiMAX devices expected to be ubiquitous in 2009

  7. Private Public Metro-Scale Mesh provides the Power of Multi-Use • Consumer mobile access: Laptops, PDAs, phones, cameras, gaming consoles • Mobile business: Trades, real estate, etc. • Voice over Wi-Fi: MVNO, cellular compliment and replacement • Content services: Advertising, mobile content distribution, local search • Public safety: mobile communications, emergency response, surveillance cameras • Municipal automation: traffic controllers and cameras, parking meters, AMR • Municipal policy: digital inclusion, economic development, disaster avoidance and recovery Multi-Use Increases Revenue and Improves ROI

  10. Tropos Featured Customers • Oklahoma City: 640 sq mi first-responder network • New Orleans: 100+ camera video surveillance network in high-crime areas converted to consumer access and enlarged after Katrina • Tucson: Mobile trauma triage • Corpus Christi: 100+ sq mi network, automated meter reading and more • St. Cloud: Economic development amenity for 28,000 residents • Philadelphia: Digital inclusion • Mountain View: Ad-supported public access network • Chaska, Moorhead, Lompoc and others: City-wide third pipe for residential access • Madrid and other Spanish cities: Traffic surveillance • Puerto Rico: UPR – Student Network Access • China, Japan and the U.K.: Improved coverage and operations in eight container ports • Australia: Open pit mine operations A wide variety of applications deployed around the world

  11. BT Wireless Cities

  12. Home Business Wi-Fi hotspots BT Mobility and Convergence Vision Wireless broadband Wireless Broadband at the heart of our strategy Wireless cities Wireless broadband Wireless Broadband is about taking Broadband Mobile

  13. Consumer devices are a key driver of Wi-Fi growth Widely adopted by the mass market today Wi-Fi handsets forecast to increase nearly 1300% through to 2010* 245.9 million Wi-Fi portable devices globally by 2010** 22 million in the UK alone by 2011 * Wi-Fi Alliance has already certified over 3000 products Wi-Fi Networks are expanding Over 142,407 free and paid Wi-Fi hotspots in 132 countries Over 300 wireless cities deployed Mobile WiMAX will take time to offer a credible alternative Fixed WiMAX available today. Useful for infrastructure but limited use for end users Mobile spectrum auction due to take place late 2007 / early 2008 Mobile Devices not available till 2008/9 Mass market will take at least 5 years to mature Wi-Fi is today’s technology choice BT delivered Wi-Fi Networks* * Infonetics Research ** Wireless Cities, BT Openzone, Wi-Fi Consumer & Business networks

  14. Wireless Cities Vision Helping make the city an attractive place to live and work Supporting city “front line” staff with innovative mobile worker applications Providing city visitors with the information they need when and where they need it Remote traffic congestion monitoring, cashless parking payments Providing a safer, cleaner street environment, improving public security - CCTV, noise and pollution monitoring Platform for education and remote learning Supporting social inclusion programmes Supporting care in the community initiatives

  15. City of Houston Award

  16. City of Houston – Muni WiFi objectives

  17. City of Houston - Architecture 95% outdoor coverage, 90% indoor coverage To be build within 24 months from start date

  18. Wi-Fi/WiMAX Overview

  19. Today’s Macro-Cell WiMAX Topology • ~1 base-station per 2 square Kilometers in urban/suburban areas • 30+ MHz of spectrum in 2.3 GHz, 2.5 GHz or 3.5 GHz band • Challenges with this approach • Existing cellular antenna overlay, may not achieve sufficient coverage for broadband data • Coverage challenges, including indoor penetration • Capacity not uniformly distributed • < 25% of the cell gets true broadband (>1Mbps uplink)

  20. Macro-Cell Coverage Pico-Cell Coverage • Legend: • Deep Blue: > 1Mbps uplink • Light Blue: < 1Mbps uplink Hybrid & Pico-Cell Approach Benefits • Better coverage • More uniform client coverage • Macro-cell model: >1Mbps for 25% of mobile users • Pico-cell model: >1Mbps for 95% of mobile users • Improved indoor coverage (larger subscriber base) • Supports high and symmetric data rates • Higher data rates at the cell-edge • Higher capacity • Efficient use of licensed spectrum resources • Opportunistic use of WiFi frequencies • More evenly distributed capacity • Optimized client links operating at high data rates • Scale capacity with usage by adding pico-cells

  21. MetroMesh™ NG Pico-Cell Mesh Architecture Capacity injection (WiMAX 802.16e / 802.16d / Fiber) WiMAX 802.16j mesh (future) Wi-Fi client access (optional) Wi-Fi mesh (802.11g, 802.11a) > 250M Wi-Fi client devices • Licensed spectrum • Optimized client link • Picocells offer true broadband coverage WiMAX client access Unlicensed spectrum = Fat Wireless Pipe Backhaul using 500MHz of unlicensed vs. 30MHz of licensed

  22. Using Unlicensed Spectrum within the Mesh • Can leverage ~500 MHz of unlicensed spectrum • Preserve scarce licensed spectrum for WiMAX client access • Unlicensed but “routed spectrum”: SABRE intelligence routes around interference, congestion, unavailability and unreliability issues • Can leverage Tropos MetroMesh NG intelligence • Self-configuring, self-healing network architecture • Dynamic frequency selection for interference avoidance • Per-packet data-rate and transmit-power selection to maximize throughput and capacity • SABRE policy-based routing flexibility • Flexible, operator-specifiable policies on use of unlicensed (SABRE™) • Example 1: Incorporate preference for mesh transport using unlicensed, with fallback to licensed if interference is encountered • Example 2: Always use licensed-only for mesh transport • Example 3: Always use unlicensed-only for mesh transport • Example 3: Use 4.9 GHz within the mesh only to transport public safety traffic

  23. Summary: MetroMesh™ NG Pico-Cell Mesh Benefits • Better coverage • More uniform client coverage including indoors • Supports true broadband with symmetric bandwidth • Higher throughput at the cell edge • Evenly-distributed broadband capacity • Optimum use of licensed spectrum resources • Efficient use of Wi-Fi frequencies • Optimized client links operating at high data rates • Scale capacity with usage by adding picocells, decreasing cell size • Smooth integration with macro-cell deployments • Fully interoperable and compatible with macro-cell WiMAX 802.16e network architecture • Optional support for 4.9 GHz for public safety applications and 2.4 GHz/Wi-Fi support for additional monetization opportunities
