This isn't the first time that Dish has asked the FCC to hold off on a review of Softbank's deal. Back on January 16th, the satellite television company asked the FCC to delay its examination of the Softbank deal because of Sprint's attempt to buy the remaining shares of network wholesaler Clearwire that it doesn't already own. FCC Chairman Julius Genachowski has already gone on record as saying that he expected the original Softbank deal to close next month. The delay would help Dish gain more traction for its bid.
Genachowski has in the past, expressed hope that Dish would become a wireless carrier to add competition to the business. The agency has already approved Dish's request to use some of the spectrum originally designed for its satellites, to be used for cellular communications.
