The Federal Communications Commission (FCC) has extended the 180-day deadline for reviewing a proposed deal between Verizon Wireless and several cablecos to account for filing delays, Reuters reports. The FCC said it would add an additional 21 days to the review period as Verizon Wireless and the cable operators failed to meet filing deadlines for additional information requested by the agency. In a deal first announced in December 2011, Verizon Wireless hopes to buy USD3.9 billion worth of wireless spectrum from SpectrumCo, a joint venture between Comcast Corporation, Time Warner Cable (TWC) and Bright House Networks. The deal includes a total of 122 Advanced Wireless Services (AWS) spectrum licences, covering around 259 million people, while in return the cablecos would be allowed to resell Verizon’s mobile services. Last month CommsUpdate reported that Sprint Nextel and DirecTV, among others, called on the FCC to delay the ruling, saying that they needed more time to study the deal in order to gauge its likely impact.
