Frequencies in the 37 GHz band, ranging from 37-37.5 GHz, 37.5-40 GHz and 42.5-43.5 GHz, were added for the upcoming sale. But apart from the 37 GHz band, all the spectrum was put on sale last year, and though the government netted a record ₹1,50,173 crore from the auction, a lot of spectrum remained unsold. All that quantum of spectrum is being put on sale again.
