Bharti Airtel, Vodafone Essar and Idea Cellular have asked the Department of Telecommunications (DoT) to auction 2G spectrum.

Prior to this, the Telecom Commission (TC) had reached a consensus on December 9, 2011, to impose a one-time fee on incumbent GSM operators on the excess spectrum they hold beyond the 6.2-MHz limit.

Also, the Commission had reportedly reached a consensus on permitting liberal merger and acquisition (M&A) norms to promote consolidation in the Indian telecom market.

Further, the Commission has agreed that the annual revenue share be fixed at a uniform 8 per cent for all operators.

Currently, the revenue share varies, based on factors such as service and region.
