Nokia said this week that it won a GSM network expansion deal with Sichuan Unicom, a subsidiary of China Unicom. Nokia said the deal marks a significant milestone for the vendor in entering the GSM market in Sichuan and West China. Nortel made a deal with China's Ministry of Railways (MOR) to provide GSM Railway (GSM-R) switching centers. The centers will enable digital mobile signaling and operational communications along passenger lines spanning 20 of China's 31 provinces. With all the talk of 3G delays in China, it looks like vendors are working hard to get some GSM business in the interim.
