India8217;s Bharti Airtel plans to launch its 4G services in Bangalore within 30 days,an executive said,after the country8217;s largest mobile phone carrier launched the service in the eastern city of Kolkata earlier on Tuesday.

Bharti and its rivals paid a total 385.43 billion rupees 7.5 billion to buy fourth-generation 4G wireless broadband spectrum in a 2010 government auction,which saw bids at much higher prices than initially expected.

Bharti managed to win 4G spectrum in just four of India8217;s 22 telecoms zones in the auction,paying 33.14 billion rupees for spectrum in the Maharashtra,Karnataka,Kolkata and Punjab zones.
