Menezes said that Dish TV customers would probably need to buy an added outdoor antenna to connect to LTE towers to make the broadband connection work.
Dish officials didn't respond when asked to comment on how the broadband would work, however.
Menezes and Phillip Redman, an analyst at Gartner, said it isn't clear how far SoftBank would be willing to go yo out-bid Dish, or whether Sprint will entertain the Dish bid at all.
Ultimately, Menezes said that the Dish offer may pressure Softbank and Sprint into a partnership with Dish.
"The Dish deal is definitely better for Sprint than SoftBank's in the sense that Sprint could realize huge spectrum gains, while all it it gets from SoftBank is money and new management ideas," Menezes said.
The most affected customers in the deal would be existing Dish customers, Menezes added. "I don't see mobile service customers necessarily flocking to Sprint just because of a Dish tie-in," he said.
Both AT&T and Verizon have had offerings that tied in to Dish and DirecTV before, but they were not a big customer draw.
