Bharti Airtel, Indian's largest mobile phone operator, is reportedly preparing to roll out 4G telecommunication services in the Delhi circle by end of 2013 or early 2014.

A person familiar with Airtel's plans revealed that the telecom operator's 4G technology would provide much faster download speeds than the third-generation technology.

Speaking on the condition of anonymity, the person also said that the roll out of Airtel's 4G network in Delhi service area is being handled by Chinese telecom equipment maker Huawei Technologies.

Bharti Airtel's 4G telecommunications services are already available in Kolkata, Pune, Bangalore and Chandigarh. If the recent report is correct, then Delhi would be the fifth city to receive the company's 4G technology.

A separate report suggests that Bharti Airtel has decreased the salary of its Chairman & Executive Director Sunil Mittal by nearly 10 per cent, from Rs 25 crore in the last fiscal to Rs 22.55 crore this fiscal.

The network provider had been suffering fall in net income for nearly three years. However, it managed to arrest the steep fall in net profit in the April-June quarter of current fiscal, for which it reported a fall of 9.6 per cent in net profit at Rs 688.9 crore.

Bharti Airtel stock closed at Rs 341.9 a share, at a gain of 4.5 per cent at BSE on Monday.
