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

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
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

Wi-Fi is todays technology choice
  • 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

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 care in the community initiatives
Supporting social inclusion programmes

Wi-Fi/WiMAX Overview
19
Todays 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
  • lt 25 of the cell gets true broadband (gt1Mbps
    uplink)

20
Hybrid Pico-Cell Approach Benefits
  • Better coverage
  • More uniform client coverage
  • Macro-cell model gt1Mbps for 25 of mobile users
  • Pico-cell model gt1Mbps 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

  • Optimized client link
  • Picocells offer true broadband coverage

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
