Carriers, such as China Telecom and China Unicom, exhibited 3G and fixed-mobile convergence services, such as mobile video monitoring and family gateway systems that allow users to access the Internet through their televisions.
China Telecom, which acquired China Unicom's code division multiple access (CDMA) network under the reorganization, unveiled its mobile services under the brand Surfing (Tianyi in Chinese).
China Telecom also said it has expanded its video-monitoring services to work on mobile phones.
"People can use it to monitor babies or elderly relatives and control the cameras through phone handsets," said an official at the China Telecom booth.
China Telecom also displayed enhanced 3G networks with a peak speed that will enable users to download three songs in a second.
Handset-based music and TV services, wireless data cards and mobile Internet will become the most profitable sectors for the company in the 3G era, said Shi Chengbin, an official at China Unicom's Shanghai branch.
China Unicom displayed its Wideband CDMA services for family users, which will allow users to access the Internet through TVs or phone handsets. Once 3G licenses are granted, China Unicom will be able to upgrade GSM to WCDMA in
