Calcutta, Apr 10 (PTI): After launching 4G LTE services here on Tuesday, Bharti Airtel will shortly roll them out in the other three circles of Karnataka, Punjab and Maharashtra (excluding Mumbai).

”We will launch the 4G LTE service in Bangalore this month, followed by Pune and Chandigarh,” Bharti Airtel Chairman Sunil Mittal said here on Tuesday.

Mittal said that the TD-LTE (Long Term Evolution) technology adopted by Airtel would be the platform for future broadband revolution.

”We hope that this technology would be emulated and followed by those who got Braodband Wireless Access (BWA) licenses,” he said at the launch event.

The network for rolling out Airtel's 4G LTE services in the city had been built by Chinese telecom equipment maker ZTE. Airtel is the first mobile operator to launch 4G services in the country.

The company that got the Broadband Wireless Association (BWA) licence for Calcutta circle was Reliance Industries-owned Infotel.

The first mobile service was also launched in Calcutta in 1995.
