T-Mobile spent $4.2 billion bidding on wireless spectrum the past three weeks to expand the geography of its cellular network as it tries to climb up from the No. 4 rung on the U.S. wireless carrier ladder. Though the FCC set up the spectrum auction–one of its largest in 12 years–to give advantages to smaller telecom companies, the big vendors still dominated, filling holes in their national coverage.
T-Mobile bought 116 radio frequency spectrum licenses in the first 18 days of bidding, as it tries to catch up to Cingular, Sprint Nextel, and Verizon Wireless in terms of coverage.
