"The Department of Telecom and Trai have been reviewing the process. My own view is 50 per cent in-band spectrum cap, I think is a good check to have because nobody wants to have entire spectrum in one operator hands that takes away competition, ecosystem," Mittal said here.
He, however, said "the overall cap of 25 per cent needs relaxation as there are operators that have 35-40 per cent market share and operating at a lower level. You should liberally look at the spectrum cap issue," he said at an event, where Telecom Minister Ravi Shankar Prasad was also present.
In the consultation paper for spectrum auction of seven bands, Trai has sought comments if a cap on the spectrum holding within all bands in sub-1 GHz frequencies be specified and in such a case, should the existing provision of band specific cap (50 per cent of total spectrum assigned in a band) be done away with.

"The way data is growing, we need more spectrum and I am glad that on your request Trai has come out with a consultation paper in terms of putting out recommendations to you," Mittal said.
Regarding spectrum trading guidelines, Mittal said he was a votary of free trading of spectrum as it was bought in auction. However, the last trading deal announced has made his case extremely weak as the deal price was much higher than the auction discovered price.
"Therefore, the middle ground could be spectrum price discovered in auction should be the base on which the government should charge but in case of any windfall gains, a substantial portion must be shared with the government," Mittal said.
