While UAS/Cmts operators were paying between 2 percent and
5 percent spectrum usage charges, depending on the quantum of spectrum held, broadband wireless access operators were asked to pay only 1 percent of the adjusted gross revenue as spectrum usage charges.
However, even in its final report, the CAG pointed out that the DoT did not maintain parity in the spectrum
charges that were being paid by the UAS/Cmts operators providing voice services
and operators who were using broadband wireless access to provide voice services.
