GSM subscribers forecast
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.
3G Modes Compared and WCDMA development
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

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.

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.
