China Mobile rolls out 4G offensive

Firm expects to have 500m users of service by end of next year

China Mobile Communications Corp, the world's largest telecom carrier by subscribers, is planning a 4G explosion next year to maintain its edge in the telecom market amid stiff competition from domestic peers.

Shang Bing, chairman of China Mobile, said on Tuesday: "Though we have built the world's largest 4G network, we need to expand it to more consumers and put more cutting-edge technologies into commercial application."
