South Korea's largest mobile operator, SK Telecom Co has announced plans to run a trial network in its home market of TD-SCDMA, Time Division-Synchronous Code Division Multiple Access, or TD-SCDMA, was developed by the Chinese Academy of Telecommunications Technology in collaboration with Datang Telecom Technology and Germany's Siemens AG, and was included among the family of UMTS standards by the ITU.

April 10 2007, Chinese Premier Wen Jiabao stopped by an SK Telecom test center that is working on a TD-SCDMA network, After greeting SK Group Chairman Chey Tae-won, Premier Wen entered the test center and used a cell phone to make a long-distance video call to Wang Xudong, China's information industry minister, in Beijing. After finishing his phone call, Wen said, "It's surprising how clear the screen is. I feel very happy about working with SK Group."

3G wireless modules will capture only 30 percent of the M2M (machine-to-machine) communications market by 2012, a new report from ABI Research forecasts. The study predicts that 3G will only become the technology of choice when "bandwidth demands and economics" require it.

"Future-proofing," the research firm says, will not play a major role over the next five years in 3G M2M market development. According to ABI, cellular M2M applications traditionally have not required high-speed connections; rather, cellular 2G technologies like GPRS and CDMA 1xRTT have been adequate.

In 2006, however, high-speed wireless M2M applications began appearing, creating a demand for 3G M2M technology, adds ABI. "Municipal Wi-Fi and WiMAX will both challenge 3G cellular technology as the most suitable methods to achieve high-speed M2M communications for many applications and in many locales," says ABI Research analyst Sam Lucero.

High-speed wireless M2M will find its "natural uses" where the need for high bandwidth outweighs the added cost, ABI adds. Such uses are expected to include:

Fixed-wireless terminals that use cellular backhaul
Multimedia content delivery to point-of-sale terminals such as digital-marketing displays
High-speed vehicle electronics connectivity, including real-time navigation information
Remote information display, used, for example, in digital mobile advertising
Video surveillance, where wireless CCTV backhaul permits camera deployment without the need for cabled connections at each location

"WiMAX and (especially) municipal Wi-Fi offer attractive alternatives to CDMA 1xEV-DO or HSDPA 3G technologies for wide-area wireless M2M," stated Lucero. "They are both more cost-effective and operationally efficient. With backing by Intel, as well as key carriers worldwide, WiMAX and municipal Wi-Fi will feature as important high-speed wireless M2M networks in the coming years."
