Legislation Introduced in US Senate to Inventory Radio Spectrum -- Two US Senators -- Democrat John Kerry of Massachusetts and Republican Olympia Snowe of Maine -- have introduced a bill in the Senate that would mandate an inventory of radio spectrum bands managed by the National Telecommunications and Information Administration (NTIA) and the Federal Communications Commission. The inventory would include those frequencies between 300 MHz-3.5 GHz managed by the two agencies.
