China Unveils Long-Awaited Shake-Up of Telecom Industry

E-mail Print PDF

BEIJING -- China unveiled plans for a long-awaited shake-up of its huge telecommunications sector that could enhance competition among its carriers and, eventually, lead to billions of dollars in new contracts for global wireless equipment companies.

The restructuring, announced Saturday after years of preparation, will reshape China's telecom industry, one of the world's most lucrative with total revenue last year of 728 billion yuan ($104.85 billion).

It will meld six main state-owned telecom companies into three full-service carriers offering both fixed-line and wireless service nationwide. That will mean two more robust rivals for China Mobile Ltd., the world's biggest wireless carrier with about 400 million subscriber accounts, which now dominates its sole wireless competitor.

E-mail Print PDF

Trial use of TD in Guangzhou, Shenzhen, Beijing and Tianjin

I received five mobile phone models early this year, including ZTE U80 TD/GSM double-mode and single-standby model, ZTE U980 TD/EDGE double-mode and double-standby model, Samsung T578 TD/GSM double-mode and double-standby model, Longcheer TD290 TD/GSM double-mode and single-standby model and Yulong 6260 TD/GSM double-mode and double-standby model. Because the USIM card supplied with T578 model was unable to connect to Internet in Guangzhou, it was replaced by a USIM card (phone number: 15710702091) for network construction testing provided by East Compeace on March 10. Then the trial use in Guangzhou and Shenzhen started and lasted till end of March. The trial use is summarized below:

1. Ordinary phone: From March 10 to 22, over times calls were made with this mobile phone to GSM mobile phones, CDMA mobile phones, phones in little smart system or regular phones in Beijing, Tianjin and Shanghai from Guangzhou or via Shenzhen TD network. The communication time varied from 12 seconds to 43 minutes and all had clear voice.
