Aruba’s Chuck Lukaszewski talks Wi-Fi 6 and venues on the Stadium Tech Report Podcast!

Welcome back to the Stadium Tech Report podcast! We are extremely happy to kick off the new series of recorded chats by welcoming Chuck Lukaszewski to talk about the new Wi-Fi 6 standard and how it’s going to help networks inside large public venues like sports stadiums. If you don’t know Chuck, he is Vice President of Wireless Strategy & Standards at Aruba, a Hewlett Packard Enterprise company, and has been working with Wi-Fi for a long, long time.

Chuck has also been a fantastic contributor to MSR’s ongoing attempt to educate our readers — his essay on LTE over unlicensed spectrum is always worth a read — and this conversation continues on the learning path. We open up with some general descriptions of what Wi-Fi 6 is, and then dive down into what its new features mean for venues specifically. About halfway through, you can even hear Chuck give me a lesson on the misconceptions I had about security comparisons between Wi-Fi and LTE networks — click above and start listening!

With almost 2,000 access points and the possibility of more than 100,000 Ohio State fans logging on, it was a good bet to think that the new Wi-Fi network at Ohio Stadium would produce some big numbers when it went live. And now, we have numbers to back up that bet, as according to the school, the new Wi-Fi network saw 13.3 terabytes of data used during the season home opener Aug. 31 vs. Florida Atlantic.

We’ll have a full profile of the network from our in-person visit to the home opener in our upcoming Fall Stadium Tech Report issue, but we wanted to share these numbers with our readers as soon as we got them, because we know interest in the network at “the Horseshoe” is high. Using Wi-Fi gear from Aruba, a Hewlett Packard Enterprise company, in a design and deployment by AmpThink, the network saw 47,137 unique connections at the hope opener, out of 103,228 fans in attendance. The peak concurrent connection number for the day was 28,900, according to the school.

The network performed similarly a week later in a home game against Cincinnati, with 12.7 TB recorded from 47,579 unique connections (out of 104,089 in attendance). The peak concurrent connection number for the second game was 29,500, according to the school.

The big, open lower bowl at Ohio Stadium was covered mainly by handrail AP enclosures, of which there are approximately 600 across all levels of the stadium, many with two APs in each enclosure. Look for more details (and lots more pictures!) in our upcoming profile!

The unveiling of the latest Super Bowl banner by the New England Patriots helped lead to another record night of Wi-Fi usage at Gillette Stadium, with 11.58 terabytes of data used by fans at Sunday night’s 33-3 win over the Pittsburgh Steelers.

According to figures from Gillette Wi-Fi provider Extreme Networks, 44,906 of the 65,878 in attendance Sunday night connected to the Wi-Fi network at some point, a take rate of 68 percent. The peak concurrent number of users on the network was 34,982, which according to Extreme happened when the Patriots unveiled their latest championship banner.

Of the 11.58 TB total, Extreme said 4.56 TB was used during pregame, followed by 6.58 TB used during the game and another 440 GB used during postgame. Extreme also said the stadium network saw a peak data transfer rate of 23.24 Gbps. The 11.58 TB mark is the highest recorded at the well-connected Gillette, topping the 9.76 TB mark seen during a Taylor Swift concert last year. In our unofficial records of top Wi-Fi single-day events, Sunday’s total is now the biggest non-playoff NFL game performance, and another sign that fan wireless data demands continue to grow.

AT&T launching 5G-powered ‘fan experiences’ at AT&T Stadium for Cowboys opener

AT&T is launching what it calls ‘5G experiences’ for fans at AT&T Stadium on Sunday during the Dallas Cowboys’ NFL home opener, including some augmented-reality experiences that will let fans take selfies with huge-sized virtual NFL players or dodge virtual tacklers in an AR-type game.

While the 5G network powering the experiences inside the stadium won’t be open or available for general use, AT&T said it will have Samsung Galaxy S10 5G phones on hand in several places around the venue for fans to test out the applications that AT&T claims “couldn’t be done wirelessly at this level before 5G.” And even though 5G networks are still a long ways away from being a mainstream reality for most wireless customers, you can expect the largest U.S. carriers to fight a 5G marketing battle all fall around football stadiums, especially at NFL venues where NFL partner Verizon is already at work installing 5G test networks for use this season. In fact, Verizon also has a press announcement out today about having installed 5G services in 13 NFL stadiums. So get ready, wireless types, it’s 5G season.

Here at MSR we will try to keep our heads above any claims of stadiums being the “first” 5G-enabled or 5G-ready until such networks are prevalent and available for any and all visitors. That being said, the activations planned by AT&T for Sunday’s Cowboys home opener against the New York Giants sound kind of cool, so if any MSR readers are on hand for the game please do try them out and send us a field report or at least a selfie or two.

According to an AT&T press release, the 5G-powered experiences available at the game Sunday will include a thing called “Hype Up Chants,” where fans will be able to see a 36-foot tall version of Cowboys players Dak Prescott and Ezekial Elliott among others by viewing them through the camera of a provided Samsung phone. Fans will also be able to record their own end zone dance next to virtual teammates, over a provided 3-D video again powered by the 5G network and a Samsung phone.

On the stadium’s east side fans will be able to “pose with the pros,” again recording a virtual video with players like Elliott in what AT&T is calling an “immersive column,” a setup connected to the 5G network via a Netgear Nighthawk 5G mobile hotspot. And at the stadium’s club level, another set of Samsung phones will be available to show off live player and team stats in a broadcast-like AR format, while other fans will get to play a virtual football game where they will dodge “virtual defensive robots,” who may or may not be more effective than the real humans on the football field.

We have an email in to AT&T to find out more details if possible, including any other vendors involved in AT&T’s millimeter-wave 5G setup inside its namesake arena. Stay tuned for updates as they become available. Below are some renderings of how the experiences are supposed to look.

First Look: Inside Chase Center, the Golden State Warriors’ new home

The first event is coming up fast, but Mobile Sports Report got a sneak peek inside Chase Center, the new home of the Golden State Warriors, thanks to the photographic efforts of one of our “field scout” team members, Brian Nitenson, who attended a season ticket-holders event this weekend. Our first reaction to the photo stream is simply ‘wow!,’ and we can’t wait until we can see an event there live.

Since the wireless networks aren’t really fully operational yet we don’t have any speed tests from Brian’s visit but from his pictures we can see multiple Wi-Fi and DAS antenna deployments so it’s a safe bet that the connectivity will be first-rate. There is also some hint of advanced technology being used in the concessions department — note the photo of a sign instructing fans toward a credit-card kiosk operation — which makes sense given the main business of the arena’s title sponsor.

Much more coverage from Chase Center to follow this fall, but for now take a look at the NBA’s newest arena, a privately financed jewel on the San Francisco bay.

Bigger is better for San Francisco Giants with new video board at Oracle Park

When it comes time for a stadium to replace its main video board, the rule of thumb almost always is that bigger is better.

The San Francisco Giants certainly think so, as the team replaced its main outfield display this season with a new screen that is three and a half times bigger, and a lot sharper than the previous technology.

Though he said it wasn’t a slam-dunk decision internally, Giants senior vice president and chief information officer Bill Schlough said the team eventually went with as big a screen as the park’s existing infrastructure allowed, with improving the fan experience as the main driver.

What fans at the newly renamed Oracle Park are looking at this season is a 71-foot high, 153-foot wide LED board from Mitsubishi, with a 10-mm pixel pitch and resolution of 2,160 x 4,672, dense enough to support 4K content when it becomes available. The new board stretches to fill the space between two light towers in centerfield, replacing a previous arrangement of a smaller board surrounded by a batch of static display signs, an arrangement that was part of the internal controversy, according to Schlough.

Is digital always better?

Editor’s note: This profile is from our most recent issue of our VENUE DISPLAY REPORT series, where we focus on telling the stories of successful venue display technology deployments and the business opportunities these deployments enable. This issue also contains profiles of the innovative directory displays at the Mall of America, and an in-depth look at display technology at U.S. Bank Stadium during the Final Four! START READING the issue today!

“It was an incredibly controversial topic inside the organization,” said Schlough of the debate about how big the Giants’ new screen should be. Though conventional wisdom says that digital signage can produce greater revenue than fixed signage due to its ability to change on demand, Schlough said that some salespeople and sponsors still like the permanence of a fixed display.

“When you are selling sponsorships there are pros and cons for each method,” Schlough said. “With digital you can have moments of exclusivity, where one sponsor can take over all the signage, and you can animate to capture the attention of fans.”

But the cons of digital signs include the fact that they can be turned off, a fact that may make a signage sponsor less willing to commit if it knows its message may be blanked out — as opposed to a static sign, which can’t be changed. According to Schlough the debate about the size of the new board was one of the most contentious technology decisions he’s seen during his 20-year career at the Giants, with only the team’s then-controversial decision to put Wi-Fi APs under seats (in 2013) coming close.

In the end the bigger-is-better side won out, in what Schlough said is part a nod to everyday experience with TVs as well as a hedge against the fact that stadium video screens often stay in place for many years.

“When’s the last time you came home with a TV from Best Buy and said, ‘it’s too big’ ?” Schlough joked.

On the more serious side, he did note that the Giants’ previous screen had lasted for 12 years — going from being just the third high-definition screen in all of Major League Baseball when it was installed to being the fifth-smallest and second-oldest in MLB by last season.

“You don’t get that many bites at the apple, and if you’re only making this kind of an investment every 10 years, there’s no way you can go too big,” Schlough said. The new board is now the third-largest in MLB, behind only Cleveland and Seattle. The team did seem to compromise for the fixed-sign contingent, adding more static display spots mounted to the light tower structures for this season. The new board also forced the Giants to replace an analog clock, installing a digital version a bit higher above the new board.

More stats, and 4K to come

In researching technology for its new $10 million investment, Schlough said the Giants went around to a host of other stadiums that had recently replaced their video boards, including the University of Nebraska’s Memorial Stadium, the Baltimore Ravens’ M&T Bank Stadium, and the Colorado Rockies’ Coors Field, among others. After looking at display technology from all the leading vendors, Schlough said the Giants stuck with longtime “great partner” Mitsubishi, who had provided the screen the Giants installed in 2007, which replaced an older board that was present when the venue opened in 2000.

With all the new space to play with, the Giants are already finding new things to show on the board, including a much longer list of statistics.

“It’s not just batting averages anymore, fans today want all the new things like launch velocity,” Schlough said. “Our baseball analytics team said ‘let’s give fans everything we’re looking at ourselves,’ so we’re putting up as much as we can.”

On a recent visit to Oracle Park, Mobile Sports Report witnessed the board in action, and came away incredibly impressed by the clarity and stunning scenes made possible by the large screen. Schlough wasn’t kidding about the wealth of new stats available for each batter, and the size and resolution made the between-innings video entertainment jump right out at you. Our favorites were a live shot of the San Francisco skyline from Treasure Island (see video below) and a between-inning t-shirt giveaway that inadvertently had MSR editor Paul Kapustka visible on the screen for a few almost-famous moments.

In the future, Schlough forsees the Giants showing 4K resolution content, which has not yet arrived for stadiums on the production side — but knowing that it someday will, he’s happy that the team has “future proofed” its main display for when 4K content arrives.

So far, Schlough said, fan response has been “awesome” in support of the new screen, making it clear that people in the seats agree that a bigger screen was a great choice.

“In the end the fans won,” Schlough said.
