Telecom Minister A Raja said on Tuesday he was waiting for directions from the finance and the law Ministries on the timing for auctioning of third generation radio waves, which will help telcos offer faster data services.

"There is no clarity yet. I am waiting for directions from the finance ministry and the law ministry and have not got any from them," Raja told PTI when asked whether the auction would happen this fiscal or in the next.

Earlier in the day, Cabinet Secretary K M Chandrasekhar, who was heading the high-level committee to monitor vacation of spectrum by the defence forces, said revenues would get preference to timing for 3G auction.

"I don't think it really particularly matters if it happens this year or the next year.. They (DoT and the Finance Ministry) will take the decision based on how the revenue can be maximised," he said.
