Fixed WiMAX available today. Useful for infrastructure
but limited use for end users
Mobile spectrum auction due to take place
late 2007 / early 2008

Wi-Fi/WiMAX Overview
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)

Hybrid & Pico-Cell Approach Benefits
• Better coverage
– More uniform client coverage
Macro-Cell 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
Pico-Cell Coverage
• 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

devices
• Licensed spectrum
• Optimized client link
• Picocells offer true broadband coverage
Unlicensed spectrum = Fat Wireless Pipe
Backhaul using 500MHz of unlicensed vs. 30MHz
of licensed
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

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
