A “Super Bowl” atmosphere with plenty of built-in social media sharing moments helped push the NFL regular-season opener at U.S. Bank Stadium to a total of 4.32 terabytes of data used on the Wi-Fi network, according to Minnesota Vikings networking officials.

The Vikings’ 17-14 win over the rival Green Bay Packers on Sept. 18 christened the stadium in fine fashion, with 66,800 fans packing the new arena. Even without any promotion for the network or the accompanying team app, almost 32,000 of the fans present logged on to the Wi-Fi network at some point of the game day, according to Tod Caflisch, vice president and chief technical officer for Minnesota Vikings Football. The network also saw a peak concurrent-user mark of 17,500, according to Caflisch.

In addition to the exciting game, the first regular season NFL game at U.S. Bank Stadium saw extensive pregame activities, including historic Vikings player introductions, a mock Viking ship with a fire-breathing dragon, and former Vikings coach Bud Grant blowing the Gjallarhorn. The day also included a halftime show with an orchestra and a Prince tribute, a list of events that no doubt produced multiple selfies, photos and videos shared quickly over social media via the in-stadium network.

No promotion for Wi-Fi, app or food ordering

“I’m not surprised [at the data and connection numbers],” said Caflisch, citing all the festive happenings. Adding to the network usage was also the fact that many fans may have been visiting the stadium for the first time, and recording those moments, a process that had Caflisch worried beforehand about Wi-Fi coverage near the main entry.

“My biggest concern was the huge crowds waiting outside the security area before the start of the game,” Caflisch said. As part of their deal with team app provider VenueNext, U.S. Bank Stadium is also using the firm’s ticket scanners, which run on Wi-Fi.

“We have Wi-Fi there for the ticket scanning, but I was a little concerned about how the sheer density of people would affect the scanning,” Caflisch said. As it turned out, all systems were go, even with the big number of fans coming in the large glass-door gateways.

“It was a non-factor,” Caflisch said.

Other than a few small issues with specific Wi-Fi APs, Caflisch said the Cisco gear-based Wi-Fi and IPTV networks “really worked well” for the home opener, perhaps the sternest test yet for the new deployment from network design and deployment firm AmpThink. Caflisch, who joined the Vikings’ tech team this past summer from the Detroit Red Wings’ Joe Louis Arena, said he initially “had my reservations” about the stadium’s use of railing-mounted APs as the main delivery system in the seating bowl.

“I had not heard of a railing solution being the main plan — mostly I’d seen it as a retrofit,” said Caflisch. “But the numbers we’ve seen shows it’s working very well.”

While he didn’t provide a number, Caflisch also said that use of the express food ordering service in the team app doubled from preseason totals, again without any external promotion. Right now, the service, which lets fans order and pay for concessions via their phone and then pick up the food and drink at an express window, is only available to certain parts of the stadium.

“We haven’t promoted the app, the ordering or the Wi-Fi to wait and see what the stress loads were,” Caflisch said. “We’re definitely planning to promote all three now.”
