The number of mobile users in Asia is still the most. The main

service is still the voice call. But the proportion of data service willkeep increasing

Better User Experiences

Voice performance can compare to that of fixed network

Efficiently support various multi-media services

Support medium and high speed mobility (e.g. high-speedtrain)

Stable service performance

Lower terminal power consumption.

Less call setup time for special services, including emergencyphone call, PoC (Push to talk over Celluar), GoTa (Globalopen Trunking architecture, which has been used in China),

and so on.

Air Interface Evolution Phase

Phase 1: Multi-carrier HRPD(MC)

Proposed target completion of first specification in the February of2006.

Primary objectives are to increase peak data rates and maintainbackward compatibility

Prioritize enhancements that minimize impact to infrastructurehardware

Support bandwidth allocations up to 20MHz and up to 15carriers (1.25MHz)

Air Interface Evolution Phase

Phase 2 : Enhanced cdma2000

Target completion of associated technical study andspecification publication by mid-2007.

The relevant technologies in phase 2 are likely to include:

Enhanced CDMA

Enhanced equalizersIFDMA

Interference cancellation

MIMO and other advanced antenna technologies

OFDM(A)

Other advanced coding techniques
