WASHINGTON/SAN FRANCISCO (Reuters) – AT&T Inc (T.N) spent close to half the total in the record-setting U.S. sale of airwaves for mobile data, with Dish Network Corp (DISH.O) spending heavily to manage a surprise win at No.2 ahead of Verizon, results showed on Friday. AT&T bid a total of $18.2 billion to win licenses of so-called AWS-3 spectrum. Dish itself did not win any licenses, but had invested in bidding partners SNR Wireless LicenseCo LLC and Northstar Wireless LLC, which bid a total of $13.3 billion.
