How do you bring new technology into a building and institution that embraces history as an integral part of its brand? There may be many answers but in the sports stadium world, Notre Dame’s renovation of its hallowed football stadium and the addition of high-speed Wi-Fi look like a good example for any other venues trying to solve the same issues.

As part of its $400 million “Campus Crossing” stadium renovation, the University of Notre Dame made adding a high-definition stadium Wi-Fi network a priority, according to Rob Kelly, associate athletics director of ticketing, premium and technology for the school. Though such big projects often face budget trimming en route to completion, Kelly said the network was never on the chopping block.

“I’m pleased to say, Wi-FI was a priority,” said Kelly during an MSR visit in August. “It will power what we want to do for the future. Our vision is greater, and the things we want to do won’t work without the network.”

Future is now for Wi-Fi, video boards, premium seating

An outside look at the new construction surrounding the ‘old’ stadium bowl

Future aside, the new technology reality at Notre Dame Stadium is a huge step forward for a facility that first appeared in 1930, when the legendary coach Knute Rockne led the Fighting Irish football team. Since then the old concrete oval underwent only one significant upgrade, a 1997 enhancement that added another ring to the top of the stadium, boosting capacity from 59,075 to 80,795.

The Campus Crossing project, however, takes Notre Dame Stadium into a new era completely. By basically building three new buildings onto the back of the east, west and south sides of the stadium, Notre Dame added the ability to now have expanded premium club areas and seating sections, added classroom and other office space, and the ability to finally have a huge TV screen to show replays, a big upgrade to the experience from the Notre Dame games of the past.

Thanks to the video board, “we won’t have to text family or friends not at the game to find out if a player was in or out of bounds,” said Kelly. Though the tradition of attending a game in the same facility where legends like Rockne, Ara Parseghian and Joe Montana roamed the field is part of the game-day attraction, Kelly said that Notre Dame fans’ visits to away games made them well aware of amenities that were becoming commonplace elsewhere.

“That old saying about ‘you don’t know what you don’t have’ just wasn’t true anymore,” said Kelly, who notes that currently most Notre Dame seasons will see the team playing in one or two NFL venues for prime-time contests. Brought in right at the start of the Crossroads project, Kelly said he had to become an “instant expert” on premium seating and on technology, especially on the Wi-Fi front. That wasn’t all bad, since it meant multiple visits to other stadiums to evaluate their technology deployments and seating options.

On the Wi-Fi front, Notre Dame paid special attention to Wi-Fi deployments in Green Bay (since Lambeau Field is similar to Notre Dame Stadium in construction and layout) and in Minnesota, where the new U.S. Bank Stadium had opened. The biggest question for Notre Dame’s Wi-Fi deployment in its no-overhang exposed bowl was about which method would be used — with the early leaders being under-seat or top-down placement of Wi-Fi APs. According to Kelly, a railing-mounted solution like the one used at U.S. Bank Stadium was not originally given much thought, mainly because the lower bowl seating area at Notre Dame Stadium didn’t have any handrails.

Shake down the Wi-Fi … from the railings

Though the new top part of the bowl required handrails for safety regulations when it was added in 1997, the lower bowl was historically exempt from those considerations, Kelly said. Notre Dame information architect John Buysse, one of the leads on the school’s network team, said the first reactions during network planning meetings rejected the idea of Wi-Fi on railings, with debate suggesting that the lower-bowl aisles weren’t wide enough.

Wi-Fi enclosures blend well in the concourse area

Under-seat deployment AP would be a challenge as well, for both the extra cost of drilling more holes through the concrete — many at locations “below grade,” or in the dirt, since the playing field is well below ground level — as well as a lack of space between the floor and the bench seats.

“Whoever had an AP [under the bench] would be miserable,” Buysse said.

Somewhere during the process, however, a survey of alumni found that the lack of railings in the lower bowl was a serious safety concern, especially during the rainy and snowy parts of the season.

“The alumni complained about how difficult it was” to negotiate getting to their lower-bowl seats without any handrails, Buysse said. With the ability to score a double positive with one move — adding handrails for safety and for Wi-Fi — the railing-mounted AP plan moved in for the win.

“It also really helped that Minnesota had done it [handrail deployments] and had success,” said Buysse, who got good performance statistics from the Vikings to back up the railing-mount idea. After seeing those numbers, he said, “any potential concerns went away.”

So far this season, the network has already performed like a winner. For Notre Dame’s Sept. 9 home game against Georgia, the network saw 6.2 terabytes of data used, the highest total ever recorded for a college football game.

Handrail AP mounts, Kelly said, “were better than the alternative of under-seat — it costs less, and there are fewer holes in the concrete.”

It also didn’t hurt, Kelly said, to make a double positive from a single move.

“Adding handrails [for safety] was a positive, and better connectivity was another positive,” Kelly said. And the fact that the enclosures look cool — with a snappy ND logo embossed into each cover — also probably doesn’t hurt.

AmpThink steps up to lead Wi-Fi deployment

The custom AP enclosures with the ND logo embossed into the molded plastic were courtesy of AmpThink, a Dallas-area firm that in most of its previous history had provided its Wi-Fi skills in a specialist or subcontractor role where it had full responsibility for network deployments. But with an increasing amount of experience in its resume — including doing designs for several of the recent Super Bowl networks, as well as new network installs at Texas A&M University and U.S. Bank Stadium, among others — AmpThink bid and won the lead on the Notre Dame Wi-Fi project, another football-size stadium project on a list that also includes the renovated Wi-Fi network at the Carolina Panthers’ Bank of America Stadium in Charlotte, N.C., and the ongoing renovation at the Alamodome in San Antonio, which will host the 2018 NCAA Men’s Final Four.

In AmpThink, Notre Dame found a partner not just with technical skills but also with the appreciation with how making things that look good as well as perform well matters. One look at the custom Wi-Fi AP handrail enclosures tells you a lot about this commitment, when you see the sharp, widely recognizable yet understated “ND” logo stamped into each ABS plastic casing.

AmpThink execs showing off the gear during a recent tour pointed out details like the slightly roughened surface, finished that way to keep any scratches from showing. AmpThink also made sure all the logos were horizontal when installed, no small feat with numerous different angles of slope on various railings.

“There are different [railing] angles all over, and only one of the ones AmpThink delivered didn’t match — and they had a spare to fix it on hand,” Buysse said.

“AmpThink has been a tremendous partner,” said Kelly, noting the early help AmpThink provided by bringing in demo units to mock up what the deployment would look like.

Of the 1,096 total Wi-Fi APs in the new network, a full 685 serve the seating bowl, Buysse said. For the below-grade APs located near the bottom of the seating bowl, AmpThink and Notre Dame brought bandwidth to the railings by drilling a trench down the sides of stairways and covering the cables with rubber gaskets afterward. The APs in the bowl are mainly Cisco 3800 units, which have two radios each. Buysse said the bowl network will be exclusively on 5 GHz channels, like many other stadiums these days.

AmpThink’s engineering ingenuity is apparent in other places as well — for flat-ceiling AP locations like those in suites, the firm developed an AP enclosure that can be installed by one person, instead of having to have electricians and other construction specialists teaming up to get all the work done. It might not sound particularly interesting, but when you are installing hundreds of APs in far-flung locations, finding a way to save time on each one ends up being a big benefit in the end.

Even with all the new construction the main concourses of Notre Dame stadium have successfully combined the old hallowed-ground feel with modern amentities like new and more concessions stands, as well as Wi-Fi and DAS antennas painted and mounted in ways to keep them out of direct sight. Our speedtest in the concourse area showed a connection of 70 Mbps on the download and 52 Mbps up. Crown Castle built and operates the neutral-host DAS, which already has AT&T and Verizon Wireless working with T-Mobile set to join in soon.

Though there weren’t any fans on hand yet, our speedtests taken in late August were impressive, with Wi-Fi readings of 69 Mbps on the download and 70 Mbps on the upload in the upper deck benches on the stadium’s east side; we also got a reading of 67.56 / 68.68 inside the new premium club area on the west side; and a test of Verizon DAS connections at 46.68 / 11.39, also on the west side of the stadium.

TV production, mobile app plans ready for the future

The next tale to tell from Notre Dame Stadium may be on the content and application side, where the Fighting Irish are just getting ready to play with their new toys. At the SEAT Conference in Atlanta this summer, Notre Dame execs talked about starting slow with the stadium mobile app, not trying to do too much so that fans wouldn’t be turned off by the approach if features failed. For this season the app will focus mainly on digital ticketing, allowing fans to show tickets, transfer tickets via email, or donate unused tickets back to the university. Kelly said the school will explore using a portal for Wi-Fi login in the future, to “reinforce” the value of the app.

On the video production end, the building on the stadium’s west side provided the space to create a multi-headed content production facility that hosts the new “Notre Dame Studios,” an internal startup of sorts that will centralize all kinds of video and streaming production not just for sports but for all the content being created all over the South Bend, Ind., campus and beyond. For football game days, the production facilities can be used by network crews, who no longer will need to bring a separate production truck to the venue.

For Notre Dame fans, the improvements bring the facility well to the forefront of the connected-stadium world, as well as for premium seating, especially for those with access to the rooftop club areas, where fans can relax on outside couches with an excellent view of the field, a commanding view of the greater South Bend landscape, and excellent connectivity for their mobile devices. All in the old stadium with its sturdy brick-and-concrete foundations, and the statue of Rockne out front, ready to shake down the thunder and then share that experience on Facebook or Snapchat.

“There’s a fine line in finding the balance between aesthetics and performance,” Kelly said. “Leadership understood that we couldn’t compromise the aesthetics of Notre Dame Stadium.”

But, Kelly added, he’s also “never heard that people don’t want better cell coverage.” While the changes may be startling to veteran Notre Dame fans — especially the video board — Kelly thinks the end result will be another positive, as the practice of combining technology and tradition with a commitment to quality becomes apparent.

“I think everyone will be pleasantly surprised,” he said.

Orlando City Stadium adds high-density Wi-Fi for soccer fans

Resilient. Connected. Reliable. Even before its new stadium opened in March of this year, Orlando City SC, the Major League Soccer franchise in central Florida, knew exactly what it wanted from fan-facing Wi-Fi.

Leading that list was networking infrastructure to support the stadium’s 25,500 capacity. The team needed to be able to deliver live streaming video to fans through the team’s LionNation app. And they wanted a way to begin collecting user info and building relationships with fans, according to Renato Reis, CIO for the club.

And with so many professional sports teams having already installed wireless infrastructure, Reis knew there was no reason to reinvent the Wi-Fi wheel. “I had the privilege to travel and interview other organizations,” he said, including the Hard Rock Stadium in Miami where the NFL’s Dolphins and the University of Miami both play football, as well as MetLife Stadium in East Rutherford, N.J., shared by the NFL’s Jets and Giants. Reis said Orlando City SC’s technology drew heavily on the experience and deployment of Levi’s Stadium in Santa Clara, Calif. “I used what I learned,” he laughed.

Paying their own way

Orlando City is barely 3 years old and played its first two seasons in the nearby Citrus Bowl, now called Camping World Stadium.

Under-seat Wi-Fi deployment at Orlando City Stadium.

After some confusion with the City of Orlando, Orange County and the state of Florida over money and budget for a new stadium, Orlando City SC’s ownership abandoned a public-private partnership to go its own way. Orlando City Stadium was built with private funds and opened in time for this year’s opener. Orlando City SC shares the venue with the Orlando Pride, the women’s professional soccer team.

“We had a brand-new stadium and no installed Wi-Fi, two factors that really benefited us,” Reis told Mobile Sports Report. “We planned the position of our antennas and leveraged lessons from other organizations to design something from scratch and build for the future.”

Orlando City SC had some help there. The MLS franchise partnered with managed service provider Spectrum Communications; Spectrum in turn has a longstanding partnership with Orlando City’s equipment vendor, Cisco. Together, they installed networking gear, lots of new fiber-optic cable, and the wireless infrastructure that rides atop the stadium’s 10-Gbps backbone network.

The fan-facing Wi-Fi consists of more than 550 wireless access points around the stadium, or about one AP for every 45 users. The APs are installed under seats, in handrails and on posts. “It was more of a challenge to find the right places, design-wise, for APs to keep them out of people’s line of vision,” Reis said.

Supporting streaming video

AP density and processing power were important considerations for Orlando City SC. With such dense coverage, each AP delivers 50-80 Mbps per user, Reis said. That ensures that users of the team’s LionNation app enjoy high performance when using its streaming video capability; users posting to social media or checking email also get faster throughput, he added.

That sort of performance is essential, especially for users of the premium version ($8.99) of the LionNation app. In addition to live-streaming video, premium members get access to behind-the-scenes content, as well as 10 percent discounts off food, drink and merchandise purchases (and points for every dollar spent). They also get priority access to post-season tickets and single-game tickets.

ISP powerhouse and Cisco partner Spectrum Communications helped with the stadium’s engineering and remains active in day-to-day management, said Reis. Spectrum performed three rounds of Wi-Fi tuning and collecting data to see where usage was greatest. No surprise: Entry gates and concession areas, according to Reis. They then made adjustments, repointing APs where needed, thus ensuring bandwidth is available where it’s needed most.

Orlando City SC has also been testing wireless food ordering in one stadium section with 1,500 users since the beginning of the year. “The challenge there isn’t technology but rather logistics,” Reis explained.

The team is planning to extend the capability more broadly, but needs more experience to help decide how to proceed. “We’ll probably run the test for the rest of the season and make changes next year,” he said.

Reis’s biggest challenge for the moment is encouraging Wi-Fi usage – and also persuading users to register if they’re not on the app. Even with Orlando City Stadium’s Wi-Fi coverage, most users will stick to cellular (the stadium’s DAS network is serviced by AT&T, Verizon T-Mobile and Sprint), he said.

“The problem I’m trying to solve is who is at the stadium,” Reis explained, adding that the only information he has is that a fan bought four tickets, for example, and when they get scanned at the gates. So how to learn more? “Most landing pages are boring,” he laughed; still, he’s considering offering different incentives for Wi-Fi users to check in.

“Can I loyal-ize you so I can learn what you like, what offers are more appealing, what you enjoy and don’t?” Reis asked. That’s a primary challenge for most sports teams, entertainment companies and ecommerce entities. Luckily for Reis and the Orlando City SC, he’s got the bandwidth, backbone and people resources to learn more about fans and build those relationships going forward.

New Colorado State stadium has winning Wi-Fi network

Even though it’s not completely finished, the Wi-Fi network at Colorado State University’s new football stadium has already shown strong signs of promise, signaling a future with great connectivity for Rams fans at their new on-campus venue.

Being built by integrator 5 Bars, the network is in its final phases of completion, with enough of it turned on to get some positive results in the first two home games for Colorado State this season.

On Aug. 26, during Colorado State’s 58-27 win over visiting Oregon State, a sellout crowd of 37,583 crammed into the new on-campus venue for the Fort Collins, Colo., school. During the inaugural event, the not-yet-finished Wi-Fi network nevertheless saw 5,891 unique connections during the day with a peak concurrent number of 3,680 users at 3 p.m. local time, according to 5 Bars. Even with most of the under-seat Wi-Fi connections not yet online (5 Bars said the network was about at 35 percent capacity), the network still saw 2.7 terabytes of data used, an average of 458 MB per connected user.

Some under-seat Wi-Fi APs needed conduit cored through the concrete steps

A couple weeks later, Mobile Sports Report was in the house for CSU’s second home game, a 38-10 victory over Abilene Christian. With 27,038 fans in attendance, many wearing bright orange to celebrate CSU’s “Ag Day” heritage (the official school colors are green and gold), the network saw 4,548 unique users and 1.8 TB of traffic, according to 5 Bars.

Under-seat coverage impressive

If there is a design tactic that seems to have paid off, it’s 5 Bars decision to go under-seat with Wi-Fi APs in most of the lower seating bowl. With 250 in-bowl APs out of the estimated 419 total APs used in the venue, many are in under-seat enclosures, both in premium areas with seats with backs, as well as in seating areas with metal benches.

And while building a stadium from scratch with Wi-Fi in mind usually means under-seat deployment can be easier, 5 Bars found that in the end it needed to place some APs in different spots, leading to some on-site construction that included coring holes in concrete steps to thread conduit across some aisles. The end result, however, is impressive, with MSR speed tests hitting the mid-50 Mbps and into the 60-Mbps marks for both download and upload speeds in most of the lower bowl seating, with tests taken before the game in an empty stadium.

The on-campus proximity of the new stadium is a welcome change for CSU fans

But even later, with orange-clad CSU fans filling the seats, the working Wi-Fi network still performed admirably, with a 63.58 down and 48.35 up reading in the middle of the student section on the stadium’s east side during the first quarter. Closer to the end of the first quarter, we got a 24.33 / 9.96 reading in the lower section of the west side, the most tightly packed area in the stadium that day.

Light standards and beer gardens

While under-seat placements may be the workhorses at CSU’s new stadium, there are also plenty of overhead APs to fill in the gaps, such as at the top of the lower-bowl sections, mounted underneath the overhang. There are also Wi-Fi APs as well as DAS antennas on the large light standards that top the east stands. Though we didn’t test the DAS network, 5 Bars has a neutral host deployment that currently has Verizon Wireless online, with AT&T and T-Mobile to follow soon. Sprint is scheduled to be added next year, with support for Sprint’s 2.5 GHz spectrum, 5 Bars said.

One thing that makes the new CSU stadium unique is the New Belgium Brewing beer garden that fills the north end zone of the stadium. With several rows of long, stand-up tabletops where fans can sip a beer while watching the game, as well as a bar area behind, the beer garden was already a popular place to hang out, as evidenced by the big line that formed shortly after the stadium opened.

And thanks to the structures over the bar area, the beer garden was well covered by Wi-Fi APs mounted above the taps. Even down in one of the stand-up rows close to the field we were still able to get a Wi-Fi reading of 55.69 down and 24.11 up. We also taste-tested New Belgium’s “Old Aggie Lager,” a brew made specifically by the local company for CSU. It’s crisp and refreshing, especially on a sunny Saturday afternoon. And it goes perfectly with good Wi-Fi.

Notre Dame sees 6.2 TB of Wi-Fi traffic for Georgia game

The final score on the football field may not have made Fighting Irish fans happy, but on the connectivity side of things the new Wi-Fi network at Notre Dame Stadium scored a big win with 6.2 terabytes of traffic used during Notre Dame’s Sept. 9 home game against Georgia.

Deployed by AmpThink, the new Wi-Fi network is part of a $400 stadium renovation called Campus Crossroads that debuted in time for this year’s college football season. Mobile Sports Report got a look at the new stadium renovations, which include new premium seating areas and a large video board, during an August football scrimmage event that was open to fans.

On Sept. 3, the Irish formally opened the stadium with a home game against Temple, which Notre Dame won 49-16. According to Notre Dame, the new Wi-Fi network saw 4.8 TB of traffic for the season opener, with 21,395 unique client connections and a peak concurrent connection number of 15,800. For the Sept. 9 game against Georgia, a prime-time night game that saw the Irish just fall on the short end of a 20-19 score, the network saw 6.2 TB of traffic, with 25,856 uniques and 19,475 peak concurrent connections.

By our unofficial records, the 6.2 TB mark is the highest Wi-Fi traffic number recorded for a single-day college event. The previous high mark was a 5.7 TB total reported by Texas A&M for a 2015 season game against Alabama. (Any other big marks out there that we don’t know about, please let us know!)

Total attendance for both Notre Dame games this season was 77,622, which sounds like the new sellout capacity for the stadium, a number not previously reported since the renovation. Notre Dame can probably expect another big network experience on Oct. 21, when the Irish host Pac-12 rival USC.

NFL Wi-Fi update: AT&T Stadium adds 667 APs

With today’s main NFL season schedule already underway, here is a quick update on all the NFL stadium Wi-Fi updates we know about that are either finished or still under construction for the 2017 season:

— AT&T Stadium, already the location of the biggest (by number of APs) stadium network we know of, is in the process of adding another 667 APs, a project scheduled to be finished in the next few weeks. According to John Winborn, CIO for the Dallas Cowboys Football Club, the new APs are all the Cisco 3800 two-radio models, and will be installed on the stadium’s 400-level seating area.

When done, AT&T Stadium will have 2,567 APs, with plans to add another 400 in the upcoming offseason. After that, said Winborn, AT&T Stadium will “be out of locations in the stadium to place additional APs without additional spectrum opening up.” (editor’s note: This post has been updated to correct an error in reporting that previously stated that 600 new APs had been installed.)

— In Atlanta, the fans are getting ready for the first regular-season game at the new Mercedes-Benz Stadium, which will have nearly 1,800 APs total, many of those under the seats in the bowl.

— As previously reported in MSR, Denver’s Sports Authority Field at Mile High is in the process of ripping and replacing its former Wi-Fi network, installing 1,470 new Cisco 3800s in a project scheduled for completion by late October/early November.

— In Philadephia, Lincoln Financial Field is in the process of switching from an Extreme Networks deployment to a new one using Wi-Fi gear from Panasonic. More details on this project are promised later this fall.

— In Seattle, the Seahawks’ IT team is adding additional APs to improve coverage in the four corners of the upper seating sections of CenturyLink Field, according to Chip Suttles, vice president of technology for the Seahawks. Suttles said a full offseason tuning assessment with gear provider Extreme Networks also saw a new channel plan put in place, and “multiple Wi-Fi antenna orientations to improve coverage.”

— Detroit’s Ford Field also got a Wi-Fi (and DAS) upgrade over the past offseason, a revamp that will now allow all visitors, and not just Verizon Wireless customers, to use the stadium Wi-Fi.

— Chicago Bears fans will finally have free Wi-Fi this season, after being forced to pay for access previously.

— Following the announcement that the Arizona Cardinals were switching from CDW to Cox Business as the exclusive technology provider for the University of Phoenix Stadium, the UoP Stadium network was set for some additional APs and some network tuning ahead of the NFL season, according to Mark Feller, vice president of technology for the Cardinals.
