It is now official — we have a new record for most Wi-Fi data used at a single-day event, as fans at U.S. Bank Stadium in Minneapolis for Super Bowl 52 used 16.31 terabytes of data on the Wi-Fi network.

According to statistics compiled by Extreme Networks during the Philadelphia Eagles’ thrilling 41-33 victory over the New England Patriots Sunday night, the AmpThink-designed network which uses Cisco Wi-Fi gear also saw 40,033 unique users — 59 percent of the 67,612 in attendance — a new top percentage total for any single-game network experience we’ve been told about. (The Dallas Cowboys saw approximately 46,700 unique Wi-Fi users during a playoff game last season, about 50 percent of attendance at AT&T Stadium.)

The network also saw a peak concurrent connection of 25,670 users, and a peak data transfer rate of 7.867 Gbps, according to the numbers released by Extreme. Though Extreme gear was not used in the operation of the network, Extreme has a partnership deal with the NFL under which it provides the “official” network analytics reports from the Super Bowl.

The final total of 16.31 TB easily puts Super Bowl 52 ahead of the last two Super Bowls when it comes to Wi-Fi data use. Last year at NRG Stadium in Houston, there was 11.8 TB of Wi-Fi use recorded, and at Super Bowl 50 in 2016 there was 10.1 TB of Wi-Fi data used at Levi’s Stadium in Santa Clara, Calif. So in reverse chronological order, the last three Super Bowls are the top three Wi-Fi events, indicating that data demand growth at the NFL’s biggest game shows no sign of slowing down. Combined with the 50.2 TB of cellular data used in and around the stadium on game day, Super Bowl 52 saw a total of 66.51 TB of wireless traffic Sunday in Minneapolis.

Super Bowl 52 represented perhaps a leap of faith, in that the handrail-enclosure Wi-Fi design had not yet seen a stress test like that found at the NFL’s biggest event. Now looking ahead to hosting the 2019 Men’s NCAA Basketball Final Four, David Kingsbury, director of IT for U.S. Bank Stadium, can be forgiven for wanting to take a bit of a victory lap before we set our Wi-Fi sights on Atlanta’s Mercedes-Benz Stadium, home of Super Bowl 53.

“AmpThink, CenturyLink and Cisco designed and built a world-class wireless system for U.S. Bank Stadium that handled record-setting traffic for Super Bowl LII,’ Kingsbury said. “AmpThink president Bill Anderson and his team of amazing engineers were a pleasure to work with and the experts at Cisco Sports and Entertainment supported us throughout the multi-year planning process required for an event of this magnitude. High-density wireless networking is such a challenging issue to manage, but I am very happy with our results and wish the team in Atlanta the best next year. The bar has been raised.”

U.S. Bank Stadium in Minneapolis before the start of Super Bowl LII

‘Fan Mobile Pass’ will serve as NFL’s Super Bowl 52 app, from pregame activities to game day functions

For the second year in a row, the NFL is building its own mobile app for the Super Bowl, this time with a single-application strategy meant to cover both fan activities the week before Super Bowl LII, as well as game-day functionality at U.S. Bank Stadium in Minneapolis.

In a phone interview Thursday with Aaron Amendolia, vice president of IT services for the NFL’s office of the CIO, Amendolia said the new strategy of having a single app for pre-game and game-day activity was meant to drive adoption and eliminate confusion over which app fans might need for various Super Bowl interactions. Last year, the NFL tried to harmonize its Super Bowl app strategy but still required fans to use a separate app — the NFL Mobile app — to see game highlights and other content.

The Super Bowl LII app is now available for download, and fans can sign up on the Super Bowl app website for a chance to win tickets to the big game, while also providing personal information that Amendolia said will assist with the league’s quest to bring more “personalization” to the experience.

“There’s more gamification to the app, with the opportunity for fans to win achievements” through the week, Amendolia said. According to the sign-up web page, there will be a heavy focus on social media engagement, with promises of availability of free autographs from current and past NFL stars; the ability to take a picture of the Super Bowl trophy; and to see images of all 51 Super Bowl rings. There will also be sponsor-activation activities throughout Minneapolis, most likely at the NFL Super Bowl Live fan site on Nicollet Mall and other Super Bowl events, where presumably fans can “check in” with the app’s QR code to earn rewards.

Wayfinding maps, but no blue dots

For both the week before and game day, Amendolia said the app will have wayfinding maps, but they won’t be active “blue dot” wayfinding, even though that feature is supported in the Vikings’ own stadium app, which was developed for the Vikings by app developer VenueNext.

“We did discuss [beacon-enabled] options, but there are some challenges to that that are unique to the Super Bowl,” said Amendolia, noting things like temporary structures and closed roads for Super Bowl activities that could be harder to integrate into maps. For wayfinding beyond maps, Amendolia said there would be a heavy reliance on digital signage information in and around the stadium to help fans find their way.

Like last year, the NFL Super Bowl app will not have any functionality allowing fans to order food or drinks for delivery or express pickup, with the latter being a service that was tested at Vikings home games this season. The app will allow fans to pre-order merchandise and pick it up at locations around town during the week before the game, Amendolia said, and will also allow suite ticketholders to order merchandise for pickup during the game.

One interesting question is whether or not the Vikings will be allowed to make their own app active for the game if they make the Super Bowl by beating the Philadelphia Eagles in the NFC championship this weekend. If so, it would represent the first time an NFL team played in the Super Bowl at its home stadium, an issue never faced in the era of team apps. Vikings officials did not respond yet to questions about the possible availability of the team app for the Super Bowl, but we will update this post if and when they do.

‘Super’ Wi-Fi and DAS at U.S. Bank Stadium ready for Super Bowl 52

After Sunday’s stunning last-second victory, the Minnesota Vikings are one step closer to becoming the first team to play a Super Bowl in its own home stadium. Should the Vikings beat the Eagles in Philadelphia this weekend, Super Bowl 52 visitors should prepare for a true Norse experience inside U.S. Bank Stadium, with repeated blasts from the oversize “Gjallarhorn” and a fire-breathing dragon ship that will launch the home team onto the field. Skol!

But even if the hometown team falls short of making the big game this season, on Feb. 4, 2018 the stadium itself should do Minneapolis proud, especially when it comes to wireless connectivity. With two full regular seasons of football and numerous other events to test the networks’ capacity, both the Wi-Fi and DAS networks inside the 66,655-seat U.S. Bank Stadium appear more than ready to handle what is usually the highest single-day bandwidth stress test, namely the NFL’s yearly championship game. (Though the selfies and uploads following Sunday’s walk-off touchdown toss may have provided an early indicator of massive network use!)

In a mid-November visit to U.S. Bank Stadium for a Vikings home game against the Los Angeles Rams, Mobile Sports Report found robust coverage on both the Wi-Fi and cellular networks all around the inside of the stadium, with solid performance even amidst thick crowds of fans and even in the highest reaches of the seating bowl. Speedtests on the Wi-Fi network, built by AmpThink using Cisco gear, regularly hit marks of 40 to 50-plus Mbps in most areas, with one reading reaching 85 Mbps for download speeds.

And on the DAS side of things, Verizon Wireless, which built the neutral-host network inside U.S. Bank Stadium, said in December that it has already seen more cellular traffic on its network for a Vikings home game this season than it saw at NRG Stadium for Super Bowl LI last February. With 1,200 total antennas — approximately 300 of which were installed this past offseason — Verizon said it is ready to handle even double the traffic it saw at last year’s game, when it reported carrying 11 terabytes of data on stadium and surrounding macro networks.

Good connectivity right inside the doors

James Farstad, chief technology advisor for the Minnesota Sports Facilities Authority (MSFA), the entity that owns U.S. Bank Stadium, said he and his group are “very pleased” with the state of the wireless networks inside the venue heading toward its Super Bowl date.

“You’re never really satisfied, because you want it to be the best it can be,” said Farstad in an interview during our November visit to Minneapolis. “But generally speaking, we’re very pleased with the state of the networks.”

Those networks are tested the very moment the Vikings open the doors for home games, especially in warmer weather when the signature big glass doors — five of them, all 55 feet wide and ranging in height from 75 to 95 feet — swing out to welcome fans. As the entry that points toward downtown, the west gate can account for as much as 70 percent of the fans arriving, according to the Vikings, putting a big crush on the wireless networks in the doorway area.

To help keep people connected in crowded situations, Verizon deployed extra DAS antennas on short poles in front of both the west and east end zone concourse areas, part of a 48 percent increase in overall DAS antenna numbers added during the football offseason. Even with thick crowds streaming into the stadium, we still got a DAS speedtest of 77.35 Mbps download and 32.40 Mbps upload on the concourse just inside the west doors, and just below the Gjallarhorn.

Walking around the main level concourse, connectivity hardware is easy to see if you know what you’re looking for; part of the extensive DAS coverage includes dual antennas hanging off a single pole above wide walkway segments. And in one instance, we saw a good example of aesthetic integration, with a Wi-Fi AP attached just behind two IPTV screens, with a beacon attached to the side and a DAS antenna mounted just above everything else.

First big test of railing-mounted Wi-Fi?

Moving into the seating bowl, visitors may not know that many of the Wi-Fi network’s 1,300 APs are hiding there in plain sight — inside silver handrail enclosures, many of which now sport bright, bold section numbers to help fans find their seats. Believed to be the first big football-sized stadium that relied mainly on railing-mounted APs, the proximate network design from AmpThink is proving to be a winner in performance, producing regular-season game data totals of around 3 terabytes per event and maybe more importantly, keeping an optimal number of fans attached to the AP closest to them for the speediest connection.

Top-down antennas provide coverage for suite seating

Sitting next to AmpThink president Bill Anderson in the stadium’s press box you get a great view of the field, but it’s doubtful Anderson watches much football action given that he spends most of a game day glued to a screen that shows live detailed performance for every Wi-Fi AP in the building. While the analytics program produces a wealth of interesting data, the one metric that keeps Anderson’s attention is the one showing how many fans are connected to each AP, a number that will be no more than 50 and ideally somewhere around 25 connections if the network is performing as it should be.

On the day we visited, on Anderson’s screen there was one AP showing more than 200 devices trying to connect to it, an issue Anderson noted for immediate problem-solving. But with only a handful of others showing more than 50 connections, Anderson was confident that AmpThink has been able to figure out how to solve for the main dilemma for Wi-Fi in large enclosed structures, namely keeping APs from interfering with each
other. The large clear-plastic roof and wall areas at U.S. Bank Stadium don’t help, since they reflect RF signals to add to the network design degree of difficulty.

But the multiple railing-mount network design – which AmpThink duplicated at Notre Dame University, whose new network is seeing the highest-ever data totals seen at collegiate events – seems to be fulfilling AmpThink’s goal to produce networks with steady AP loads and consistent, high-density throughput in extremely challenging environments. The railing-mounted APs provide connectivity that couldn’t be delivered by overhead antennas, like in Notre Dame’s open concrete bowl and in U.S. Bank Stadium’s similar wide-open seating area, where no overhead structure is within 300 feet of a seat.

“I think we have a network strategy that produces good uniform performance” in venues like U.S. Bank Stadium, Anderson said. “It’s pretty darn exciting to have a formula that works.”

More antennas get DAS ready for big game

And even though Verizon knew the Super Bowl was coming to U.S. Bank Stadium when it built the neutral host DAS for the 2016 opening, it came right back this past offseason and added approximately another 300 new antennas (mainly for its own use and not for the shared DAS), all in the name of unstoppable demand for mobile bandwidth from fans attending events.

Diana Scudder, executive director for network assurance at Verizon, said in a phone interview that “the consumer appetite [for wireless data] is insatiable,” especially at the NFL’s biggest game, where DAS use has grown at a fast clip the past few years. Scudder said these days Verizon pretty much plans to see double whatever the last Super Bowl saw for each following big game, and adds network capacity accordingly. Verizon’s numbers from the past three Super Bowls are a good guide, with the carrier reporting 4.1 TB used at Super Bowl 49, 7 TB at Super Bowl 50, and 11 TB at Super Bowl 51.

AmpThink’s handrail-mounted AP enclosures seem to have played a hand in part of Verizon’s DAS upgrade, as some of the new DAS enclosures seem to mimic the Wi-Fi ones with their smaller silver enclosures. Scudder did say that Verizon used contractors to assist with the new antenna deployment enclosures and mounts, but did not cite AmpThink by name. Verizon also deployed some under-seat antenna enclosures for its upgrade, a tactic the company also used for Super Bowl 50 at Levi’s Stadium in Santa Clara, Calif.

Even up in the most nosebleed of seats — in U.S. Bank Stadium’s case, section 345, which has seats almost touching the roof in the southwest corner, we got a DAS speedtest on the Verizon network of 60.87 Mbps / 44.22 Mbps, most likely from some antennas we could see mounted just above the seats on ventilation pipes a bit toward the field. And hanging from the middle of U.S. Bank Stadium’s roof are a pair of Matsing Ball antennas, which point down to provide cellular service for media and photographers on the sidelines, as well as for floor seating for concerts and other events.

Ready to add more bandwidth on the fly

Even less unseen and probably not appreciated until it’s needed is the stadium’s backbone bandwidth, provided by sponsoring partner CenturyLink.

Though some stadiums are touting 100 Gbps pipes coming in, the U.S. Bank Stadium setup makes the venue its own ISP, according to Farstad.

With six 10-Gbps pipes that are always active — and on two separate network infrastructures for redundancy — the stadium can turn up its bandwidth on the fly, a test the venue got on its first public event.

According to Farstad, when U.S. Bank Stadium opened for the first time with a soccer game on Aug. 3, 2016, the stadium operators expected about 25,000 fans might show up for a clash between Chelsea and AC Milan. But a favorable newspaper article about the stadium led to more than 64,000 fans in the house, a surge that backed up the light-rail trains and saw the concession stands run out of food.

“We were watching the Wi-Fi system during the first break [in the soccer game] and it was coming down fast,” Farstad said. But the ability to increase capacity quickly — Farstad said that within 45 seconds, the stadium was able to provision new bandwidth, a task that in other situations could take weeks — the Wi-Fi survived the unexpected demands, proof that it should be able to handle whatever happens on Super Bowl Sunday.

“I think we can handle the Super Bowl traffic,” Farstad said.

Verizon: U.S. Bank Stadium DAS already seeing more traffic than Super Bowl 51

The trend of fans continuing to use more and more wireless data at big sporting events shows no sign of slowing down, especially after Verizon Wireless said that it’s already seeing more cellular traffic at Vikings home games this year than it saw at Super Bowl 51.

Verizon, which built the neutral-host distributed antenna system (DAS) for cellular carriers at U.S. Bank Stadium in Minneapolis, also said it increased the DAS antenna count by 48 percent at the venue this past offseason, in order to better support the expected surge coming at Super Bowl 52 on Feb. 4, 2018. At a press event at the stadium today, Verizon said it now has approximately 1,200 DAS antennas of its own at U.S. Bank Stadium.

“We’re very confident” that both the DAS and Verizon’s networks will be more than ready to handle the Super Bowl when it comes to Minneapolis at the end of this current NFL season, said Diana Scudder, executive director for network assurance at Verizon, in a phone interview earlier this week. Though the stadium opened in 2016 with a fully functional DAS, Scudder said Verizon spent the past offseason adding more capacity for its customers with additional DAS antennas in a variety of deployment methods, including antennas in enclosures both under-seat and in handrails, as well as in pole-mounted deployments along standing-room drink railings in both end zone concourses.

Though Scudder declined to say exactly how many DAS antennas there are in the building, with the new “48 percent” additional antennas Verizon said it now has 100 DAS zones throughout the venue, including the seating bowl, concourses, suites, and outdoor DAS coverage surrounding the stadium. But perhaps the most surprising reveal was that in-stadium DAS traffic at Vikings home games this season have already produced single-game numbers that Scudder said were greater than those seen inside the stadium at Super Bowl 51, held Feb. 5 at NRG Stadium in Houston. Pay attention here, because the italicized distinction is important.

Under-seat, handrail and drink-railing DAS

Given Verizon’s historic coyness on numbers, it’s no surprise that Scudder did not provide an exact number for the Vikings in-stadium DAS traffic that she said surpassed Super Bowl 51’s mark. She also didn’t disclose what the in-stadium only DAS number was for Verizon at NRG Stadium. The only reported Verizon number for DAS traffic at Super Bowl 51, 11 terabytes of traffic, includes data not just from the stadium, but also from macro network connections within a 2-mile radius of the stadium on game day, Scudder said. So far, Verizon hasn’t provided a Vikings regular-season game-day measurement for traffic outside the stadium as well. So if it’s not an apples-to-apples comparison yet, if the in-stadium marks are already higher, the bet is that whatever total number Verizon sees at Super Bowl LII, it will be greater than the 11 TB seen at Super Bowl LI.

It’s also not surprising that the DAS installation at U.S. Bank Stadium is already looking like it will surpass NRG Stadium’s marks, simply because with the advantage of greenfield construction, all networks at U.S. Bank Stadium were designed with some of the latest deployment knowledge available. At NRG Stadium, where networks were added well after construction, Verizon deployed DAS antennas under the concrete floors, an easier deployment method but one that typically produces lower throughput than other methods. And for Super Bowl 50 at Levi’s Stadium in Santa Clara, Calif., Verizon added under-seat DAS antennas in what was believed to be the first such deployment for cellular DAS.

Two DAS antennas hang from a pole above the main concourse

AmpThink, which built the Wi-Fi network in U.S. Bank Stadium relying on handrail-mounted AP enclosures, seems to have played a hand in part of Verizon’s DAS upgrade, as some of the new DAS enclosures seem to mimic the Wi-Fi ones. Scudder did say that Verizon used contractors to assist with the new antenna deployment enclosures and mounts, but did not cite AmpThink by name. The new under-seat DAS deployments and the handrail DAS deployments are Verizon-specific, meaning they are not part of the neutral host DAS that provides service for other cellular carriers.

In addition to overhead DAS antennas mounted pretty much everywhere it would make sense — below overhangs, and even in twin-antenna mounts on poles hanging down over concourse walkways — there are now a series of DAS antennas mounted on poles just above the main-concourse end-zone standing areas, where fans can lean against drink rails while watching the game. In a pregame test on Nov. 19 for a Vikings home game against the Los Angeles Rams, MSR tests saw DAS speeds of 77.35 Mpbs download and 32.40 Mbps upload on one of the end-zone concourse areas.

Even up in the most nosebleed of seats — in U.S. Bank Stadium’s case, section 345, which has seats almost touching the roof in the southwest corner, we got a DAS speedtest on the Verizon network of 60.87 Mbps / 44.22 Mbps, most likely from some antennas we could see mounted just above the seats on ventilation pipes a bit toward the field. And hanging from the middle of U.S. Bank Stadium’s roof are a pair of Matsing Ball antennas, which point down to provide cellular service for media and photographers on the sidelines, as well as for floor seating for concerts and other events.

Demand for bandwidth is ‘insatiable’

According to Scudder, any and all antennas are all needed, both for Vikings home games at the 66,200-seat venue, but also for the Super Bowl, where additional seating will host more fans, media and other attendees for the NFL’s championship game.

“The consumer appetite [for wireless data] is insatiable,” Scudder said, noting that these days Verizon pretty much plans to see double whatever the last Super Bowl saw for each following big game. Verizon’s deployments don’t end at U.S. Bank Stadium’s walls, either. According to Scudder over the past 2 years Verizon engineers have been busy adding capacity all over Minneapolis, including in downtown areas, at the Minneapolis airport, and at the nearby Mall of America.

“We’ve been partnering with the Twin Cities for 2 years now and they are very receptive and want to have the latest technology here,” Scudder said. Scudder also said that all the improvements, in DAS, small cell deployments and macro towers, will remain as permanent solutions, helping keep Minneapolis a Super-connected city even after the big game is over.
