WiMAX Macro-Cellular Topology Today
• Macro-cellular approach
– 1-4 base-stations per square mile
– 10-30 MHz of spectrum in 2.3, 2.5 or 3.5 GHz
• Challenges with this approach
–
–
–
–
–
Low uplink throughputs at the cell edge
Capacity not uniformly distributed
Difficult to scale capacity
Poor indoor penetration
Lack of support for Wi-Fi clients, lack of ubiquitous
client devices)
– Lack elegant Wi-Fi / WiMAX coexistence & evolution

Macro vs Pico Uplink Coverage Comparison
Macro-Cellular Coverage
Pico-Cellular Coverage
Assumptions:
• 1 sq mile of coverage (both architectures)
• Macro-cellular model achieves >1Mbps only for 25% of users
• Pico-cellular model achieves >1Mbps for 95% of users
Legend:
• Deep Blue: > 1Mbps uplink
• Light Blue: < 1Mbps uplink
Web 2.0, indoor coverage, hybrid networks and an elegant
WiFi to WiMAX evolution requires a pico-cell architecture

Picocell Mesh Supports all BWA Technologies
Metro-Scale Wi-Fi Mesh
True broadband needs good “link
budget.” That’s power or distance.
Mobile device power limits mean short
distance small cells
Small cells need fractional backhaul,
mobile handoffs, management, etc
Mesh makes all picocell
broadband affordable
