In an ideal world, all telcos should be paying a similar spectrum usage charge (SUC), but due to bad drafting of the rules in 2010, the government feels SUC for Broadband Wireless Access (BWA) spectrum cannot be changed from 1%. Since this would have given RJio and Bharti Airtel\u2014the two telcos who own BWA spectrum\u2014an unfair advantage, the attorney-general came up with a compromise using a weighted average. Under this formula, while Vodafone and Idea would pay an SUC of 4.7%, Bharti Airtel would pay 3.7% and RJio 2.9%. That\u2019s not fair, but as both RJio and Bharti Airtel bought more spectrum in fresh auctions, the difference would have reduced. This formula was given to Trai to make its recommendations, but what has emerged is a veritable noodle soup which is not only confusing, but also raises SUC and is bereft of logic. Let\u2019s weight the SUC, Trai says, by the revenue earned from each band\u2014but since it is not possible to segregate revenues from each band, it is not clear how Trai comes out with its \u2018factor\u2019 by which it weights the revenues. A \u2018factor\u2019 of 4.56 is used for 900 Mhz spectrum in relation to 2100 MHz spectrum\u2014how was this got and why should a pan-India \u2018factor\u2019 be used instead of a per circle one? There is no \u2018factor\u2019 given for 700\/800 MHz, so how is this to be dealt with; is the \u2018factor\u2019 the same for \u2018liberalised\u2019 and \u2018unliberalised\u2019 spectrum\u2014if not, why not? Also, since spectrum revenues will change from time to time\u2014if you use spectrum costs for calculating the \u2018factor\u2019, the same problem arises in each successive auction\u2014Trai will have to periodically come out with a new factor, making the entire process of calculating SUC more uncertain. It is true the government did not try hard enough to convince RJio\/Bharti Airtel about the flat SUC, but the weighted average formula it suggested had a logic and the differences would reduce over a few years. Since Trai will only worsen the gap, it\u2019s best to just junk the recommendations.
