The US Federal Communications Commission (FCC) says it has received 104 applications to take part in its planned 600MHz Broadcast Television Spectrum Incentive Auction. The watchdog said that of the total, only 69 applications were complete’, adding that applicants in the ‘incomplete’ category have until 6 April to re-submit their paperwork. Successful submissions include those from the likes of Verizon Wireless (bidding as Cellco Partnership d/b/a Verizon Wireless), C Spire Wireless (bidding as Cellular South Licenses), T-Mobile US, US Cellular, DoCoMo Pacific and Puerto Rico Telephone Company. The list of incomplete applications, meanwhile, includes AT&T Mobility, GTA (bidding as TeleGuam Holdings) and Liberty Spectrum. Reuters claims that the latter is a bidding vehicle for UK-based Liberty Global, which apparently has designs on the Puerto Rican wireless market. The bulk of the applications were filed by individuals, rural operators, consortiums and bidding vehicles. Full ownership disclosures are still pending, meaning that other notable companies may yet participate in the process.
