Huawei is looking to invest around US$2 billion in India over the next four year and is currently setting up a global R&D facility in the country.

The company generated revenues of US$1.5 billion in the country during the past financial year. Of that US$1.2 billion came from network infrastructure sales and the remaining US$300 million from handset and modem sales.

"2011 was a good year for Huawei because our revenue in India increased about 20 per cent... Last year, we began building a new R&D centre in Bangalore, which will house more than 5,000 people," Huawei India Chief Executive Officer Cai Liqun told the Economic Times newspaper.

The Bangalore facility is estimated to be costing US$150 million and will open next June. The company already has a global network operations centre (GNOC) in the city.

Looking ahead though, Liqun said that 2012 will be tough for the industry due to the lack of clarity about regulatory issues.

"This period will see no major investment but after all this is solved, we are confident of the Indian market," Liqun said.
