However, the company has argued that the sector is a capital intensive one as it requires constant investments because of fast-changing technology. "The telecom sector is highly capital intensive with fast changing technology cycles that require continuing investments. It is, therefore, extremely important that the industry remains viable to support the vision of Digital India," the statement reads.On November 15, CNBC-TV18 reported the committee of secretaries (CoS) plan to set a minimum price for mobile calls and data. Sources confirmed the committee has sought recommendations from the Department of Telecom (DoT) on setting a minimum charge for all tariffs for telecom players and also assessing the impact it will have on telecom operators.Airtel, Vodafone Idea and other telecom operators have to pay the government a whopping Rs 1.4 lakh crore following the recent Supreme Court order that has sent shock waves through the industry which is already grappling with losses and billions of dollars in debt.The Supreme Court, last month, upheld the government's position on including revenue from non-telecommunication businesses in calculating the annual Adjusted Gross Revenue (AGR) of telecom companies, a share of which is paid as licence and spectrum fee to the exchequer.As per the latest estimates by the telecom department, Bharti Airtel faces a liability of around Rs 62,187 crore (including share of Tata Group of companies and Telenor India), while Vodafone Idea may have to pay about Rs 54,184 crore. The remaining liability is with state-owned BSNL/MTNL and some of the shut/bankrupt telecom companies.
