Dan Williams, vice president of technology for the 49ers, said the Levi’s Stadium Wi-Fi network carried 3.3 Terabytes of data during Sunday night’s game between the Niners and the Chicago Bears, topping the 3.2 TB mark reported from Super Bowl XLVIII in February. According to Williams, out of the 70,799 that filled Levi’s Stadium Sunday, more than 30,000 fans connected to the Wi-Fi network at some point, with peak usage of 19,000 fans all connecting at one time occurring just before the 5:30 p.m. local time kickoff. According to the Super Bowl stats, the peak number of fans on Wi-Fi at that game at MetLife Stadium in New Jersey was 13,500.
“We’re pretty excited by Sunday,” said Williams, who said that the Wi-Fi network stood up well even under peak data transfer rates of 3.1 Gbps right before kickoff, and another 2.6 Gbps peak around 7:30 p.m. Around the peaks, network traffic stayed “well over 1 gig per second for three and a half hours,” Williams said.During the Niners’ first preseason game against the Denver Broncos, the Levi’s Stadium Wi-Fi network carried 2.13 TB of data, and during the Aug. 24 preseason game against San Diego there was another 1.96 TB of Wi-Fi data. The figures do not include any reporting from the stadium’s DAS network, which carries cellular traffic from AT&T, Verizon Wireless and T-Mobile customer. If preseason games are any indication, Williams expects to see numbers in the terabyte range for DAS traffic as well.
The Wi-Fi numbers from Sunday showed that fans quickly figured out a name change in the network name (or SSID). During preseason games, the Wi-Fi network was identified as “Levi’s Stadium” in a device list of available networks; on Sunday the free stadium network used the name “xfinitywifi,” reflecting the brand of Wi-Fi sponsor Comcast. Some fans might have been confused since the “xfinitywifi” SSID is the same one used by Comcast for its public Wi-Fi networks.
“Some folks may have been scratching their heads,” said Williams. “We changed the name last Monday before the opener.”
Replay app gets 7,800 views
As previously reported by MSR, the instant replay feature of the Levi’s Stadium app had its debut Sunday, and according to Williams fans watched 7,800 replays via the app. The top replay view was of the early touchdown pass from Niners QB Colin Kaepernick to Michael Crabtree, which Williams said was viewed more than 1,000 times.As MSR reported, the replay feature was somewhat limited in functionality, not working at all until late in the first half and then only offering the last two plays plus some scoring highlights for viewing. Previously, team executives had said the replay feature would offer multiple camera angles and multiple replay reviews all at the same time. According to Williams, more features will be added to the replay function in the near future.
“It’s not the finished product, by any means,” Williams said. “You’ll see some more polish on it.”
The most-used feature in the stadium app, Williams said, continues to be the food and beverage features, which allow fans to either purchase concessions for express line pickup, or to have their orders delivered to their seats. Williams said the Niners delivered 2,100 food orders to fans Sunday, the most for the Niners so far.
Perhaps the best news for Williams was the lack of complaints about the wireless network, which the team had asked fans to tweet about if they were experiencing problems. Though some fans with older devices that only work on the 2.4 GHz wireless bands might not see the same speeds as those with newer devices (which use the more roomy 5 GHz bands), Williams said his team only got a couple complaints about network issues, and one of those was solved before they could respond.
“Overall it just was a really good [wireless] experience,” said Williams, who always ends by noting that networks are never completely finished products. But with its Super Bowl-beating performance Sunday, the Levi’s Stadium network appears in midseason form.
“I think we’re close,” Williams said.
