The GSM subscribers have a durative increasing till 2009. Then later, the trends will be pull down

In 2009, the GSM subs. Quantity will reach 2.7 billion

Asia and Latin America is the dominate increasing area. The subs. will exceed 1.5 billion in 2010.


Informal forecast (reference from GSA): in 3 years, WCDMA subs. will reach 500 million. There into, there will be 300 million in Europe, 150 million in Asia Pacific and 50 million in Africa/Americas/Middle East

globally. The WCDMA subscribers have 570 million new incoming

GSM/WCDMA increasing is much greater than cdma. GSM/WCDMA will be still in the dominate

position. cdma has the superiority in the WLL application.

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.

In Oct.31, 2005, ZTE’s WCDMA network at Brunei successfully passed the DST’s radio perf

ormance 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.

Brunei, is the third biggest oil product country i
