India's biggest telecoms carrier, Bharti Airtel, has said it will invest $9bn (拢6bn) to upgrade its network, promising fewer call drop-outs, faster mobile internet speeds and broader coverage.

The plans come as rival Reliance Industries is about to launch 4G broadband internet, only a few months after Airtel did the same.

In an interview recorded just before the new investment was announced, the 蜜芽传媒's Asia Business correspondent Karishma Vaswani asked Bharti Airtel's chief executive Sunil Mittal if the competition was going to force a price war.
