China Mobile Ltd said on Friday that it has successfully deployed the world's first 4G network for high-speed trains.

The mobile network covers the 60-kilometer long Jiaxing section of the Shanghai to Hangzhou high-speed railway. It adopted the homegrown TD-LTE technology, with download speeds reaching 15 megabytes per second.

The wireless network will meet business people's daily surfing demands and support high-data traffic services, such as video and picture downloads. The network was designed to work smoothly with train speeds of more than 300 kilometers per hour.

China Mobile, the nation's biggest telecom carrier, built 18 base stations for the Jiaxing section.

Previously, China Mobile had built the world's first 4G network for a subway in Hangzhou. Download speeds at the Hangzhou subway can reach 40 megabytes per second.
