Why Mobile WiMAX?

WiFi is popular for home

networks and hot spotsbut the coverage is limited(200 – 300 ft).

Mobile WiMAX to extend

all-IP capability withmobility (4 – 10 miles).

Mobile WiMAX usesadvanced wirelesstechnologies for increasedrange and spectralefficiencies.

for Mobile/Portable Solutions

Limited Battery Life Current and in-development OFDMA/WiMAX silicon

solutions are not power efficient Sparse Coverage

Not enough infrastructure in the initial phase to providewide area coverage.

Significant opportunities are being created forsilicon providers and new service providers New architectural approach is required to achieve low power Compatibility support for existing wireless standards

Programmability to support future upgrades Emerging and low income economies will benefit from flat rate
