Bharti Airtel had reported an over 54 per cent fall in net profit at Rs 503.7 crore for the December quarter due to what it had termed as "turbulence from predatory pricing by a new operator". The Indian telecom czar said Bharti Airtel's balancesheet remains "healthy and strong" and he does not think Bharti will go into losses under competitive pressure although one can "never say never". He maintained that with improvement in technology, the cost of network is not linear.
