3G technical standards evolution 

WCDMA and WiMAX has the competition in the mobile high rate broadband access field. But there are some complementarities in the mobile data solutions.



WiMAX has the superiority in high rate access of nomadic mode which has less mobility. WCDMA is advanced in the data service seamless coverage with convenient mobility.

Brunei Excellent KPI Network

Brunei, is the third biggest oil product country in southeast-asia and the fourth biggest natural gas product country in the world.

DST, is the biggest mobile operator in Brunei



In Oct.31, 2005, ZTE’s WCDMA network at Brunei successfully passed the DST’s radio performance and service test. It began to offer wholly 3G service and achieve 2G/3G access.



With only half of the schedule, ZTE finished the network construction and optimization, DST highly commented ZTE’s efficiency in network construction “…we are very satisfied with the speed and the good quality.”



ZTE achieved the theoretical maximum value in the online single cell test.
