Abstract
Cellular data cards, which are used with laptops, netbooks, or other mobile
end devices to provide wireless Internet access, have become a hot topic with
the deployment of 3G networks in China. Among 2.5G data cards, CDMA2000 1X
mode dominated the Chinese market from 2007 since it can provide better access
speed (50-60Kbps in practice) than GPRS or EDGE. Based on In-Stat' s research,
CDMA2000 1X data card subscribers in China reached 8.5 million at the end of
2008. According to In-Stat' s consumer survey fielded in April 2009, we found
that current 2.5G data card users show low satisfaction levels with regard to
the access speed, specifically, more than 60% of respondents show
dissatisfaction with the current 2.5G network speed.
With strong support from the Chinese government, Chinese operators started 3G
network deployments in 2007, beginning with TD-SCDMA by China Mobile; coupled
with WCDMA by China Unicom, and CDMA2000 EV-DO by China Telecom in 2008. With
a total subscriber base of 634 million 2G/2.5G users in 2008 in China, there' s
still a great potential for transferring subscribers from 2G/2.5G to 3G in
2009.
