The idea of zones being given their own wireless networks is something that was bound, eventually to happen.

Dragon Lu, executive vice president of Internet value-added service provider Shenzhou Unicom, spoke of the idea of building wireless networks in zones using what he calls 4G technologies, to provide cheap VoIP (Voice over Internet Protocol) services and broadband access, as well as carry various applications including video telephony, mobile TV and location-based services.

He said, ‘Initially we plan to build wireless broadband networks in nine cities, namely Beijing, Shanghai, Shenzhen, Dongguan, Chongqing, Guangzhou, Changsha, Changde and Wuhan. We have a license to provide Internet access services in these cities. We are currently in talks with investors in the remaining 16 cities and will apply for the licenses for those cities later.’

Basically the company is setting up ‘hot zones’ which are totally covered by WiFi.
