When Taylor Swift and Ed Sheeran came to Empower Field at Mile High for concerts this summer, the hugely popular signers tested the stadium’s wireless capacity in ways it hadn’t ever been tested before. Actually, it was the fans, not the singers, who were doing the testing, moving 2.5 times the amount of data seen in a typical Denver Broncos game, said Russ Trainor, a senior vice president of information technology for the team during a media tour Saturday. Taylor Swift fans edged out Sheeran fans, moving 25 terabytes and then 26 terabytes on the two nights of her Eras tour in mid-July.
