GUWAHATI, Nov 18: Bharti Airtel has started deploying 4G technology in 900 Mhz band which it was using for 2G services, to boost indoor coverage of the high-speed mobile telephony. The re-farming of 900 Mhz spectrum band for 4G services is underway in six circles of Delhi, Kolkata, Andhra Pradesh, North East, Karnataka and Rajasthan.
Notably, the 900 Mhz band with higher propagation, especially helps in better indoor coverage for 4G and adds more muscle to Airtel’s 4G spectrum bank. The company is set to extend the exercise to more circles where it has liberalised spectrum in the 900 Mhz band. The move will enable Bharti Airtel to further boost mobile signals inside buildings compared to signals transmitted in high frequency bands of 1800 Mhz and 2300 Mhz bands that are also in use for 4G services.
