The finance ministry has recommended that operators should be charged a base entry fee to begin with and subsequently a revenue share for the use of 3G spectrum. It says the entry fee should not be so high that competition is throttled and the price of services becomes high. At the same time, the fee should not be so low that non-serious players accumulate the frequency. TRAI had suggested that there should be no entry fee for providing 3G services, while Ratan Tata had offered to pay a one-time entry fee of Rs 15 billion because it was a scarce resource.
