China Unicom gets rolling with 3G trials

Following China Telecom and China Mobile, China Unicom has now become the last of the big three Chinese operators to begin trials of its 3G network -- christened "Wo" -- with some 55 test markets lighting up this week. Happily, the trials are purely UMTS / HSPA, which means you won't need a pesky, proprietary TD-SCDMA handset to take advantage; unfortunately, though, regular commercial service won't begin until the end of the year. In the meantime, Unicom is expecting an expansion in the September time frame that would see the high-speed service expand to some 284 cities.
