  • 6. Service Requirements for High-Speed Internet Success • Easy-to-use • Affordable • Works on variety user device form-factors • Supports multiple usage models • Deliver broadband experience similar to fixed • Supports different operator types • Global roaming 6
  • 7. WiMAX is a Cornerstone For Next-Generation of Broadband Connectivity 7
  • 8. Why WiMAX? • Delivers wireless broadband anytime, anywhere • Internet technology from the ground up • One common standard delivers a global platform for mobile Internet services • Delivers the highest capacity and greatest throughput at the lowest cost - OFDMA 8
  • 9. Wireless Technologies are Evolving to OFDMA OFDMA offers better spectral efficiency – Directly translates to higher throughput and capacity SIMPLIFIES SPECTRUM Delivered ADVANCED OFDMA EFFICIENCY RF Throughput TECHNIQUES OPTIMIZES CDMA LEVERAGES SPECTRUM BANDWIDTH ALLOCATION GSM Early ’90s Mid-’90s Early ’00s Mid-’00s 9

  • 12. WiMAX is NOT a Cellular Voice Replacement • WiMAX was not developed to compete with cellular voice market WiMAX WILL Complement 3G Data Services • WiMAX is a technology choice delivering high-capacity and high- throughput data services 12
  • 13. Contrasting Wi-Fi / WiMAX / Cellular Wi-Fi • CSMA/CA WiMAX • Efficient for unpredictable traffic in an unlicensed band • Inefficient for predictable traffic (voice) • Fast dynamic scheduling • “Sharing model” designed for unlicensed band • Contention access for bandwidth requests only • No control of resource allocation policy • Resource allocation exclusively by BS – retains tight policy control by network 2G/3.xG Cellular • Efficient for both bursty, unpredictable traffic and voice • Packet overlays but based on slot based, circuit switched resource allocation • Efficient for voice traffic • Inefficient for bursty traffic (email, http) WiMAX is the Optimal Solution for Mobile Internet 13
