A similar process worked out well for both AWS and broadcasters in the refarming of the 2 GHz TV BAS band, from 1,990-2,110 MHz to 2,025-2,110 MHz; that is, from 17-MHz wide analog channels to 12-MHz wide digital channels, to free up 35 MHz of spectrum for AWS. The cost to Sprint Nextel was about $700M (WT Docket 02-55). The cost of refarming the 2.5 GHz TV BAS band would be less, since the radios from the 2 GHz transition are frequency and modulation agile, so in most cases could be reprogrammed rather than replaced. As a bonus, this would also solve the FCC's problem with 2,496-2,502 MHz BRS Channel 1 stations vs grandfathered A10 stations.
