Airtel starts refarming 2G spectrum for 4G services to enhance indoor coverage

Bharti Airtel has started deploying 4G technology in 900 megahertz band, which it was using for 2G services, across 10 telecom circles to enhance indoor coverage of the high-speed mobile telephony, according to sources involved in the process.

The refarming of 900 Mhz spectrum band for 4G services is underway in six circles of Delhi, Kolkata, Andhra Pradesh, North East, Karnataka and Rajasthan. The company will extend the exercise to more circles where it has liberalised spectrum in the 900 Mhz band, one of the sources said.

A senior Bharti Airtel executive told PTI that the company has already shut down 3G across the country and re-farmed all the 3G spectrum for 4G.
