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 highthroughput data services

12

Contrasting Wi-Fi / WiMAX / Cellular Wi-Fi WiMAX • • • •

Fast dynamic scheduling Contention access for bandwidth requests only Resource allocation exclusively by BS – retains tight policy control by network Efficient for both bursty, unpredictable traffic and voice

• • • • •

CSMA/CA Efficient for unpredictable traffic in an unlicensed band Inefficient for predictable traffic (voice) “Sharing model” designed for unlicensed band No control of resource allocation policy

2G/3.xG Cellular • • •

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
