HONG KONG, Nov 20 (Reuters) - The launch of 3G in China and India by the likes of China Mobile (0941.HK: Quote, Profile, Research) and Bharti Airtel (BRTI.BO: Quote, Profile, Research) could boost wireless broadband worldwide, sparking a boom in new offerings as millions of users sign up for services.

The move to 3G and its likely follow-on, fourth-generation (4G) Long Term Evolution (LTE) technology, is also set to help Chinese network equipment makers such as Huawei [HWT.UL] better challenge Ericsson (ERICb.ST: Quote, Profile, Research) and Nokia Siemens Networks [NOKI.UL].

"A lot of people in China and India don't have fixed line connectivity, so they will look to wireless broadband for their future online access," said Michael O'Hara, chief marketing officer of the GSM Association, a mobile industry group, on the sides of a telecoms industry event this week in Hong Kong.

India, the world's fastest-growing wireless market, with about 490 million users, has been adding about 14 million subscribers each month. The government has pencilled in revenue of 350 billion rupees ($7.6 billion) from the auction of 3G spectrum.
