In 2004, President Bush signed the Commercial Spectrum Enhancement Act (Govtrack), sponsored by Rep. Fred Upton, R-Mich., which created the Spectrum Relocation Fund to provide a centralized and streamlined funding mechanism through which federal agencies can recover the costs associated with relocating their radio communication systems from certain spectrum bands that were authorized to be auctioned for commercial purposes. The legislation appropriated such sums as required for relocation costs, which are financed by auction proceeds. [1]
