Over the course of the last year, I’ve had several requests from readers to shed more light on what goes on “behind the scenes” on my various stadium visits. Here’s the first in a planned series I’m calling “Behind the profiles,” giving you some flavor of the fun and interesting things and people I experience on my trips to check out stadium technology deployments. In honor of the basketball tournaments we are all now missing, here is my “trip diary” from my visit last year to Minneapolis to see how U.S. Bank Stadium’s Wi-Fi networks held up under the big-game stress — along with some other interesting side trips! Please let me know if you find these interesting or fun to read and I will write some more… 2019 was a true banner year for MSR visits!

Friday, April 5, 2019: Getting to the Final Four, and a Prince tribute

If there was a recurring personal theme to my Final Four trip last year it was: dealing with my hip. After almost a year of putting up with various hip-related pains in November of 2018 my situation went “off the cliff” as one doctor said, rendering me unable to do much walking or any other activity. A subsequent MRI revealed that I had almost zero cartilage left in my right hip, which meant — after other MRIs confirmed it wasn’t a problem with my back, on which I had surgery 10 years ago — that I needed a hip replacement. The good news? It would turn out to be the most pain-free major surgery I’d ever had or heard of. It was done in an outpatient procedure and I was walking without crutches five days later.

The bad news? The surgery didn’t happen until late May. In early April I was still hobbling around in a sidewinder motion, slapping lidocaine patches on and taking anti-inflammatories to make it through each day. But with the downtime associated with the surgery ahead, I had to get enough stories in my notebook to fill our spring issues — so off to Minneapolis I went.

Not all displays are digital. At MSP airport.

I can’t thank the NCAA folks enough for granting MSR a credential (they had also done so the previous year) for the Final Four. There is nothing like being on site for an actual game to see how the networks and other technologies perform. While sometimes vendors and teams are able to find us some kind of pass to get stadium access, at the biggest events having a standard media credential just makes life easier for all involved. The trick is, convincing the powers that be that MSR’s coverage is beneficial to a sports audience. (Someday, Super Bowl, someday.)

After landing at MSP airport I got an almost instant dose of what is generally called “Minnesota Nice.” I had just started ambling up the concourse toward baggage claim when a nice gent pulled up beside me in one of those golf-cart things and said, “I can spot a bum hip a mile away. Get in!”

One of the numerous airport volunteers, the “Minneapolis ambassador” spared me about 15 minutes of pain-walking, a break I welcomed. “When’s your surgery?” he asked. I told him and he replied, “you’ll kick yourself after it’s over for waiting so long. But you’ll love it.” Correct on all counts. As I got out of the cart to go down to baggage claim, a local cheerleading group was doing their moves in the airport’s main atrium. I did a quick check of the Wi-Fi (good signal) and got my bag.

The other nice thing about a real media credential is having a real room at one of the official media hotels. You do pay for it — and are required to pay for four nights no matter how many nights you are actually there — but it’s worth it. Even though our Marriott (sports writers practically live in Marriotts) was close enough to walk to the stadium (about a half-mile or so), in my condition I needed the saturation of shuttles and free rides that are de rigeur for any big event like the Final Four. After checking in I took one of the shuttles provided by Buick (NCAA sponsor) over to the stadium to get my credential and lucked out as there was no line at all, allowing me to get my badge in just a few minutes’ time.

When the Timberwolves honor local legend Prince, they get purple.

Instead of trying to find where the shuttles picked up I tapped my “insider knowledge” of Minneapolis (which I had visited several times over the past couple years) and took the light rail from right outside U.S. Bank Stadium back toward the hotel — there was a station just about a block away. Walking back I noticed one other great maybe-not-a-coincidence about the location of the media hotel I was in: There was not one, but two local brewpubs on the separate street corners from the hotel entrance. And yes, over the weekend I visited them both. Good local beer and good pub-fare food. And of course, friendly people working there.

As if I wasn’t going to see enough basketball, on Friday night I went to the Target Center to watch the Timberwolves play the Miami Heat. It was a great way to relax into the weekend, and for a change I didn’t even go around and test the Wi-Fi (we had done a profile of the arena’s new technology the year before). And the game was one of the several “Prince tribute” events the Wolves had last year, where they wore purple jerseys and a band played Prince tunes at halftime. Very cool, very Minneapolis.

Saturday, April 6: Semifinals and Sally’s Saloon

With the semifinal games not starting until early evening, there was time to kill — so I hopped on the light rail again and crossed the Mississippi River over to the University of Minnesota area, where I had a late lunch at Sally’s Saloon, one of the several iconic U of Minn watering holes. Since it was rainy and chilly out I went with a good bowl of chicken soup while I watched the end of the inaugural women’s tournament at Augusta National — what a great way to get psyched for the Masters. And what great golf! Would love to come back and tip one at Sally’s pre- or post-football game. It just has that perfect college-bar feel.

Would love to get back here to see a Minnesota hockey game. Sieve!

After the local-scene interlude I went back to the hotel and boarded an early bus to the stadium, more to get the lay of the land than to file any stories. The great thing about my work as opposed to most writers there is that I wasn’t on deadline — my profiles wouldn’t appear until our June issue. After finding my assigned seat — way back in the back row of the press area behind one of the hoops — I went down to the floor to walk around before it got closed off. It’s cool to see the setup up close, the raised playing court, the band areas and wander right up to the NBA on TNT set in one corner, where Ernie, the Jet and Chuck (no Shaq that day) were holding court, live.

The terrible sight lines from my seat were not an issue — after all, my work was not to watch the game but to wander the stadium as the games went on, testing the wireless networks while the fans gave them the ultimate selfie workout. It’s just nice to have a place to rest (especially if your hip hurts), so it’s a nice perk. As it turns out, my seating arrangement was about to get much better (for me) in short time.

I did make it back to the “press working room,” a cordoned-off wide space in the bowels of the building. Think: concrete floors, hanging-drape walls, plastic row tables and folding chairs. Those are the typical conditions for big-time sports writers, photogs, bloggers and others at the big events. With something like 2,000 credentialed media, a standard press box won’t do.

During pregame, pretty much any press pass gets you close to the floor.

While spartan, the press rooms do have everything you really need to get the job done: Nearby access to interviews (a separate stage where they bring players and coaches in), power strips everywhere for laptops and phones, and serious Wi-Fi coverage in the form of temporary antennas on poles throughout the room. There’s also a basic but efficient food and drink service, which I avoided other than getting sodas and coffee. I’d just rather get stadium food instead of steam-tray stuff, to get a sense of the venue’s “flavor” if you will. Plus as I said earlier I’m not on deadline and usually not sitting in a seat so it’s easier to just grab something as I walk around.

I next went to find my networking types and was directed to the football press box, where David Kingsbury, director of IT for the stadium, had set up the NOC HQ in what looked like a coaches’ box. Like any good general David had set up his troops for success with a wide array of healthy and not-so-healthy snacks, which I was allowed to partake in. I did enjoy my fair share of Kind bars over the weekend, and was reminded (after a taste test) just how tooth-twistingly sweet a Twinkie is. (Rejected after one bite.)

While waiting for David and his team to find some time for a quick interview I noticed that the football press box was completely empty — and thought, why not set up here as a base for my stuff and to watch the games when I needed a break? For someone who wanted to spend the day roving around the venue, the football press box was a much better base location than my official press seat (which involved a series of tunnels and stairs to get to). Plus it had comfy office-chair type seating and lots of room to spread out. Sure the court was far away, but all the multiple TVs in the press box were live, giving you as good a view as anyone’s living room couch.

The press working room was well covered by temporary Wi-Fi APs.

Sometime during the night the press folks let the rest of the media know they could sit in the football press box on a first-come, first-serve basis, and while some others eventually joined me the place never got full. While there was none of the food or beverage service usually in place for Vikings games, the added bonus of the football press box was that it has its own restrooms — something not available near the courtside seats. And in the temporary official press room, the facilites were a trucked-in port-a-potty trailer.

Since I had only made it to the final game of last year’s championship I was interested to see what the crowds would be like for the semifinals — would the second game fans skip the opener and arrive after halftime? The answer — not a chance. If you’re at the Final Four, you do the Final Four, and the stadium was packed by tipoff of game 1. And for the first time, the Final Four was allowing alcohol sales, and beer was very popular at the many concession stands and kiosks around the venue. AmpThink, which in addition to having done the regular stadium Wi-Fi had also constructed a temporary Wi-Fi network for the additional courtside seats, put all the switches it used under the stands inside waterproof cases — in part to protect from inevitable beer spills.

Over the course of the first game, I wore myself out completely, overdoing it a bit with stadium laps to see if the network held up everywhere, from the courtside seats to the highest seats up in the rafters. What impressed me was how many people were really into the games, even from far-away seats. I tried to find the perfect picture from behind, of a fan using a phone to record the action, but truthfully my opportunities were few and far between, as most people really paid attention to the action on the court. One thing that surprised me was how fast the Final Four gear sold out: There was one hat I thought was really neat, and thought “well, I’ll get one Monday.” Rookie move. By the second game Saturday, there were almost no hats at all of any kind available, with the design I wanted long gone. Next time, I’ll buy any swag on Friday at the media hotel, where there was a pop-up stand for one day only.

In between games I retreated to my football press box seat, and found some time to interview David Kingsbury and his staff about not just the Wi-Fi and DAS but the displays as well, including the temporary centerhung board which was pretty amazing for a once-only apparatus. In addition to multiple screens it also had the capability to project images onto the court itself, an extra kind of screen that really brought pregame ceremonies to life.

With the games finally over and Monday’s championship between Virginia and Texas Tech set, I walked out with the AmpThink team, skipping the masses that formed a huge line at the light rail station outside the stadium. However, we didn’t do much better trying to hail an Uber or Lyft, having to walk nine blocks away from the stadium before we could get clear enough from crowds to get an SUV driver to pick up all seven of us. A late-night dinner at an excellent brewpub capped a great night of hoops and networking. More later this weekend on the rest of the weekend, including trips to a soccer stadium and the Mall of America!

DIY method brings Wi-Fi to Rutgers basketball arena

It was a bit more complicated than a trip to Home Depot, but when the Rutgers University IT team wanted to bring fan-facing Wi-Fi to the school’s basketball arena but didn’t have the budget for a big-name contractor or vendor deal, it did what many weekend warriors do when faced with the same build vs. buy decision:

They did it themselves.

By purchasing lower-cost Wi-Fi gear and doing almost all of the design and deployment work in-house, the Rutgers IT team was able to bring a satisfactory level of coverage to the 8,000-seat Rutgers Athletic Center for a total price tag of about $62,000, according to representatives from the school’s athletic IT department. The Rutgers team first told their story at this year’s College Athletics IT peer conference in Ann Arbor, Michigan, and then provided more details in a follow-up interview with Mobile Sports Report.

The success of the DIY Wi-Fi deployment now has the Rutgers IT team looking at a similar method for bringing Wi-Fi to the school’s football stadium, starting with a localized deployment in the student section where it anticipates needs will be the highest. While fans at events in the “RAC” are probably happy for the connectivity, what might even be more important is the confidence and experience gained by the IT team by rolling up its sleeves and finding a way to deliver the network at a very reasonable price.

“The practical experience of doing this ourselves was just so much more interesting than attending conferences or networking classes,” said Jonathan Beal, systems administrator for the Rutgers athletics IT team. “I’d encourage smaller schools to look into something like this.”

Turnkey system prices ‘out of range’

Though Rutgers isn’t exactly small (enrollment is just more than 50,000 at the main campus in New Brunswick, N.J.) and while its teams are part of the major Big Ten conference, the school simply doesn’t have the athletic-department budgets that some of its conference brethren do. And while Beal said that the school is regularly approached by technology vendors with stadium Wi-Fi pitches, the million-dollar-plus price tags for deployments are a non-starter for Rutgers.

“We get approached year after year, but the quotes are always out of our [budget] range,” Beal said. But at the college IT conference in 2019, Beal said the Rutgers team was interested in a presentation from the IT department at the University of Virginia, where that school used lower-cost equipment from Wi-Fi gear provider Ubiquiti to bring Wi-Fi to Virginia’s football stadium.

While Beal said the Virginia team detailed some initial failures in their deployment program, eventually they got it on track, and inspired the Rutgers crew to see if they could chart a similar path.

“We took notes, came back to New Jersey, made some phone calls, and asked ‘how far could we go?’,” Beal said. At the beginning, the team guessed they might be able to get the school to “absorb the cost” of a test deployment either in the basketball arena or the football stadium. What tipped the project in the basketball arena’s favor was the existence of some recently installed conduits leading to the rafters, where some biometric tracking equipment and some previous DAS gear had been installed.

“For the football stadium, the [conduit] pathways are challenging – it’s going to be costly when we do that,” Beal said.

After trying out a few test APs sent over by Ubiquiti the Rutgers team felt confident in their choice of hard- ware, and submitted a budget for $60,000 – which was quickly approved. “It was an easier sell than we thought,” said Beal. “They [the administration] trusted us.”

Overhead vs. under seat

Choosing to put Wi-Fi in the rafters pointing down instead of under the seats pointing up was another con- scious choice Rutgers made after noticing a difference between how football fans and basketball fans use in-venue wireless.

“We noticed that at football games fans download [data] and watch stuff, then go back to watching the game,” Beal said. “For basketball it’s a totally different user experience. People aren’t watching things on their phones, but they are uploading to Instagram.”

So instead of solving for density and coverage (where under-seat offers a generally better experience) the Rutgers team aimed for the best upload experience for the money – which meant they could do top-down APs using line-of-sight tuning.

With a blend of a 3D rendering of the entire seating bowl (done with 360-degree cameras) and some help from Ekahau survey tools, the Rutgers team pinpointed the optimal placement points for the APs in the rafters. Since the seating in “The RAC” is mostly only on the two sides of the court – and not behind the baskets – the deployment became a fairly uncomplicated tale of two halves, with two APs for each sector.

Some tuning revealed a need to tilt the top AP down from a straight horizontal mount top since the tin roof of the RAC (which contributes to the venue’s historic reputation for being loud and an intimidating place to play) also reflects RF signals.

“Everything bounces around up there off the roof, including the RF,” said Beal. With 20 APs in the rafters (and four more down at court level for other areas) Rutgers was able to get the kind of coverage they wanted. After installing the APs with help from campus technicians – including installing backup chains to keep APs from falling onto any guests – it was time for the next step: Seeing what happened when fans joined the network.

Captive portal or free access?

Like almost every other venue that has installed Wi- Fi for guests, Rutgers struggled with how to make access available. Should it just be free to use with no restrictions, or should they try to use some kind of captive portal to get an email address or other identifying information so that the school could market to event attendees?

Joe Vassilatos, unit computing manager for the Rutgers athletics IT team, said there was some favor of a Facebook sign-in method from the Rutgers marketing team, because of the ease of identification. But Vassilatos said the IT team was “wary” of using a Facebook method, something Beal agreed with.

“We got some feedback from other schools that if you put that [Facebook sign-in] in, nobody uses the network,” said Beal.

Instead, the team opted for a sign-in method that uses a one-time SMS code with a 4-digit number that fans must enter to get access to the network. But both Beal and Vassilatos hoped that in the future there might be other ways to monetize the network – like doing offload for cellular carriers – that would allow them to make access even easier.

With the network in place during this past basketball season, Rutgers saw good numbers on the usage side, with anywhere from 600 to 800 people using the network at games this winter. Beal said network statistics showed that at most games, 20 percent of the visitors connected to the network at least once, with 10 percent having dwell times in the 20- to 50-minute range.

“That shows they’re a real user, and not just a visitor,” Beal said.

For the last three games of the season, the Rutgers network got a promotional boost from a pregame light show that included fans using their mobile devices. Part of the promotion included instructions to log on to the Wi-Fi.

But according to Beal, the network wasn’t ever a secret.

“The first thing people do in any place is check for free Wi-Fi,” Beal said. “And if people are happy with it, it’s good enough.”

Next steps: Planning for football

For this offseason, the new project for the Rutgers IT team is bringing Wi-Fi to the student section of the football stadium, where they are planning to go with an under-seat approach. According to both Beal and Vassilatos deployment there is going to be more of a tuning challenge since Rutgers students rarely sit in one place, but instead crowd the area and even stand on bleachers trying to cram in.

But with a functional Wi-Fi network now inside inside the basketball arena, a place known as “The Trapezoid of Terror” (for its unique sloped-walls architecture), the Rutgers IT team is confident of its deployment chops, and takes great pride in knowing that more events can be held there with good connectivity, including more potential money-making events like career fairs and concerts.

“In the past when we had graduation ceremonies or other events [in the RAC] we had to bring out portable Wi-Fi,” Beal said. “Now we can take that load on the sta- dium network.”

For Vassilatos, the Wi-Fi is a reason for a little bit of chest-beating.

“IT is usually very inward-facing, and this was our chance to utilize our skill set to add to the bravado of the athletic experience,” Vassilatos said. “We took this on our own to implement, and we’re better from the experience.”

NCAA cancels March Madness; MLB, NHL, MLS susupend schedules

In another somewhat inevitable decision, the NCAA on Thursday announced it was canceling the men’s and women’s Division I basketball tournaments, “as well as all remaining winter and spring NCAA championships.” After the NBA suspended its season Wednesday night and most conferences canceled their year-end tournaments in progress, it was quickly apparent that the NCAA’s Wednesday decision to hold games without fans was not going to be a good enough measure given the seriousness of the growing coronavirus pandemic.

Also on Thursday all of the other top professional sports with active schedules announced postponements to games, including Major League Baseball’s decision to postpone opening day by at least two weeks and to cancel spring training; the NHL’s decision to postpone its current season; and Major League Soccer’s decision to suspend its season for 30 days.

Statement tweets below.

Update: NCAA cancels Final Four

UPDATE, March 12: The tournaments have been canceled>

In a decision that came to be somewhat inevitable, the NCAA on Wednesday announced that due to concerns about the coronavirus, all its championship events, including the men’s and women’s division 1 basketball tournaments, would be held “with only essential staff and limited family attendance,” meaning that regular fans would not be allowed in the venues.

Though many sports teams are being dragged grudgingly into such bans, the overwhelming advice from medical experts in the past few days has been that “non-essential” large public gatherings like sports events should be canceled or closed to fans, to help combat the spread of the disease. As reports of new cases of Covid-19, the disease caused by the coronavirus, continue to expand, many cities, states and other governing bodies are already taking matters into their own hands and prohibiting any large-crowd events.

What remains to be seen with other sports, especially professional leagues like the NBA, NHL and Major League Baseball, is whether games will be canceled, moved, or played in place without fans. Also not yet known is whether the NCAA will move its Final Four games from the large arenas where they are scheduled to be played (the men’s Final Four is supposed to take place in Mercedes-Benz Stadium in Atlanta, with capacity for more than 70,000 fans) to smaller arenas. In an tweet from an AP reporter, apparently the NCAA is already considering such moves:

Here’s the full Covid-19 statement from NCAA president Mark Emmert:

NCAA mum on coronavirus tourney plans while two conferences close doors to fans

The NCAA has yet to commit to any measures to exclude fans or cancel games for its upcoming men’s and women’s basketball tournaments, even as two conferences closed their tournament doors to fans and one canceled its tournaments altogether.

In a statement on its website, the NCAA put off making a decision Tuesday, even as the Ivy League canceled its conference tournaments and the Big West and the Mid-American Conference closed their tournaments to fans. The NCAA, whose tournaments are scheduled to begin next week, said:

The NCAA continues to assess how COVID-19 impacts the conduct of our tournaments and events. We are consulting with public health officials and our COVID-19 advisory panel, who are leading experts in epidemiology and public health, and will make decisions in the coming days.

UPDATE, March 11: The NCAA now says its tourney games will be played without fans.

The Big West, whose tournaments will be played in Southern California, had a different take:

“The Big West Board of Directors, comprised of the chief executive officers of the nine member universities, strongly feel that this is a prudent way to help slow the spread of the COVID-19 virus while being sensitive to our student-athletes who have pointed towards playing in the tournament all season,” said Big West Commissioner Dennis Farrell in a statement on the conference’s website.

The Ivy League, meanwhile, canceled its year-end tournaments completely, naming the Yale men’s team and the Princeton women’s team, the leagues’ regular-season champions, as its NCAA tournament representatives.

Oklahoma leads the way with Wi-Fi 6 network at football stadium

In the long history of college football, the Univeristy of Oklahoma is a name that is always somehow in the discussion when it comes to top teams and Heisman-quality talent. And now you can add stadium Wi-Fi to the list of things Oklahoma does well, after a deployment of a 100 percent Wi-Fi 6 network at Gaylord Family-Oklahoma Memorial Stadium was in place for most of the recent football season.

Formerly among the most conspicuous Wi-Fi have-nots among big-school stadiums, the Sooners have now moved to the front of the class with a network of approximately 1,350 access points in their 80,126-seat stadium, all new models that support the emerging Wi-Fi 6 standard, also known as 802.11ax. With a deployment led by AT&T, using gear from Aruba, a Hewlett Packard Enterprise company, and a design and deployment from AmpThink, using mainly handrail-mounted enclosures in the main bowl seating areas, OU fans now have the ability to connect wirelessly at the most advanced levels, with a technology base that will support even better performance as the balance of attendee handsets starts to catch up to the network with
support for Wi-Fi 6.

“We’re very excited” about the new network, said David Payne, senior technology strategist for athletics at the University of Oklahoma’s information technology department. Payne, who has been at Oklahoma since 2003, has spent the last several years shepherding the overall stadium Wi-Fi plan into place, starting first with Wi-Fi coverage for the stadium RV parking lots, then adding initial forays into stadium Wi-Fi deployment when Oklahoma renovated the south part of the stadium three years ago. But this past offseason was the big push to full stadium coverage, a trek that included a switch in equipment vendors that was prompted by Oklahoma’s solid commitment to the emerging Wi-Fi 6 standard.

Committed to Wi-Fi 6 for the future

If there was a tricky time to pull the trigger on Wi-Fi 6, it was last summer, when not every vendor in the market could ensure it would have enough gear on hand to fully supply a big stadium like Oklahoma’s. And even though Wi-Fi 6 gear is new and generally more expensive than previous versions, for Payne and Oklahoma the long-term benefits combined with the periodic ability to refresh something as significant as a football stadium network made committing to Wi-Fi 6 somewhat of a no-brainer.

Payne, like many other big-school IT leaders, has spent years helping administrators and others at budget- deciding levels of leadership at his school try to understand the benefits of stadium-wide Wi-Fi connectivity. For many of those years, it just didn’t make sense to try to push through the multi-million-dollar expense of a project “that would only be used six or seven Saturdays a year,” Payne said. “There’s always a difficulty in telling the story of what value you receive in this since it’s different from traditional revenue streams,” Payne said. “There isn’t a direct dollar seen from Wi-Fi users.”

But with the late-2018 approval of a capital expenditure project to revamp the football stadium’s lower-bowl seating with new handrails, wider seats and other ADA-related improvements, Payne and the IT team were able to weave in the extra $3 million (out of a total project cost of $14.9 million) it would cost to bring full Wi-Fi coverage to the entire stadium.

“It’s just taking advantage of the timing to get economies of scale,” said Payne. Because of the already- planned work on the handrails, Oklahoma was able to add the AmpThink-designed handrail Wi-Fi enclosures (which use the handrail pipes to carry cabling) for a fraction of the cost of having to do that work as a separate project, Payne said. The university had also installed new backbone gear and cabling during the south end zone renovation, so that cost was already paid for.

The decision to commit to Wi-Fi 6, Payne said, was based on standard release projections from manufacturers. “We paid close attention to projected order availability and ship dates,” Payne said. “We were felt that if we were able to receive the gear by June, we could complete the project on time.”

Though some manufacturers were not sure of being able to fully deliver Wi-Fi 6 gear, Aruba, Payne said, had “high confidence” in meeting the deadlines, and won the deal. According to Payne, all the Aruba gear was shipped in time to begin construction in June.

“It’s important for us to get the full life cycle of technology, so that’s why we decided to go 100 percent Wi-Fi 6,” Payne said.

Attention to detail an AmpThink hallmark

On a visit before and during a home game against Texas Tech in late September 2019, Mobile Sports Report was able to test the live network in all parts of the stadium, with strong performance at even the highest seating levels as well as in sometimes overlooked spots like the long ramps that fans walk up to get in and out of the venue.

The Oklahoma deployment was part of a very busy summer for AmpThink, with similar Wi-Fi design and deployments at Oklahoma, Ohio State and Arkansas. Like those two others, Oklahoma’s main bowl AP deployment was in the patented AmpThink handrail enclosures, each stamped with the distinctive “OU” logo.

The handrail deployment system, which typically includes a core drill through the concrete floor to bring wiring into the handrail tubing, is now a standard process for AmpThink, following similar deployments at the Minnesota Vikings’ U.S. Bank Stadium and at Notre Dame Stadium, among others. At Oklahoma, AmpThink said it used 10 different handrail enclosure designs to fit all the necessary spaces.

AmpThink president Bill Anderson was present during our visit and took great pride in showing off some of the finer points of an AmpThink deployment, including a method of using a metal sleeve and some clever waterproof paint and sealant to ensure that no moisture finds its way into the holes used for cable delivery.

“We spend a tremendous amount of time [during deployments] making sure there isn’t any water leakage under the stands,” Anderson said. “Because you never know what is going to be below. This is a big part of what we do. We don’t just sell an enclosure.”

Concourse APs visible high on concrete posts

The same can be said of AmpThink’s overall network designs, which it monitors and tests and tweaks as fans use the system. On the game day we visited, no fewer than four AmpThink employees were at the stadium in the network control room, checking AP performance and network usage.

“We’re pretty proud of what we can do,” Anderson said about the company’s track record for network design in large venues. “We have proven formulas which we reliably implement.”

Solid speed tests throughout the venue

At 10:20 a.m. local time, just ahead of the early 11 a.m. kickoff, Mobile Sports Report started our testing inside the main-level concourse, where fans were already lining up to purchase cold beer, another first at the stadium this past season. In the midst of the entering crowds we got a speedtest of 55.9 Mbps on the download side and 43.7 Mbps on the upload side, an inkling of the strong tests we were to see everywhere we walked. In the concourses and near concession stands, a mix of overhead and wall-mounted APs provided coverage.

Up in the stands, we took our first test among the railing-mounted enclosures in section 6, row 51, just about at the 50-yard line. We got a mark of 68.2 Mbps / 58.7 Mbps before the stands were completely full. We then hiked up to row 67, which was underneath the press box overhang and served by overhead APs, not railing enclosures. There we got a speedtest of 27.8 Mbps / 49.5 Mbps, a half hour before kickoff.

One more speedtest in the lower bowl (around the 30-yard line, in row 19) netted a mark of 68.9 Mbps / 61.2 Mbps; then as we walked around to the south end zone, we got a mark of 38.7 Mbps / 64.3 Mbps in the south concourse, busy with fans getting food and drink ahead of the imminent kickoff.

The recently renovated south end of the stadium has a series of loge boxes and other premium seating options, and has an overhang which provides additional real estate for Wi-Fi AP mounting options. Ducking into a loge box (covered by overhead APs) for a quick test we got a mark of 36.8 Mbps / 54.2 Mbps just before kickoff. Moving around to the corner of the south stands for the pregame ceremonies we got a mark of 33.7 Mbps / 63.8 Mbps even as all the phones were out to capture the team run-on and school song rendition. After kickoff, we went into the crowded main east concourse and got a mark of 43.2 Mbps / 46.6 Mbps amidst all the late-arrivers.

Good coverage in the stairwells

If there is one area where stadiums sometimes skimp on wireless coverage it’s in the stairwells and pedestrian ramps, which may not seem like an important place to have connectivity. But at Oklahoma, the multiple switchbacks it takes to climb from ground level to the top seating areas are all well covered with Wi-Fi, as we got a mark of 39.9 Mbps / 29.5 Mbps during a brief rest stop on our hike to the top of the east stands.

At a concession stand on the top-level concourse we got a mark of 61.3 Mbps / 70.5 Mbps, as we admired the neatness of the core drilling we could see that got the cabling to the underside of the seating areas above. In the stands we got a mark of 57.5 Mbps / 69.5 Mbps at one of the highest rows in the stadium, row 24 of section 226, a half hour after the game’s start.

According to Payne our visit coincided with the first live game with the Wi-Fi 6 software fully turned on, part of a sort of rolling start to the network deployment which wasn’t fully live at the first game on Aug. 31.

“It wasn’t without some hiccups and headaches,” said Payne of the overall deployment, which included a small number of temporary black-colored handrail enclosures from AmpThink, which saw its single source of handrail molding material run out of supply late in the summer. According to Payne Oklahoma started the season with 966 radios working on the network, ramping up with more at each home game until reaching full capacity later in the season. AmpThink had also replaced the black enclosures by the time of our visit with the standard silver ones.

Oklahoma also experienced what other venues deploying Wi-Fi 6 may find – that some of the very oldest devices still in use may have issues in connecting to the Wi-Fi 6 equipment. Payne said one such
problem surfaced in the press box (where reporters were using older laptops) but it was solved by creating some virtual APs which were tuned to an older version of the Wi-Fi standard.

OU also didn’t widely promote the network early in the season, but by the Oct. 19 home game with West Virginia not only was the school promoting the network on the stadium’s big video boards, the IT team also added the ability for students to automatically join the stadium network via their regular WiFi@OU SSID used around campus.

With 82,620 in attendance for the West Virginia game the total number of Wi-Fi users took a big jump from the previous high, with 25,079 unique connections, according to numbers provided by Payne. When Iowa State came to Norman on Nov. 9, the network saw its highest usage with 32,673 unique users, who used approximately 4.2 terabytes of data while in the stadium.

What was also interesting to Payne was the number of devices connected using the Wi-Fi 6 standard, which currently is only supported by a small number of phones. Payne noted that the first week OU had the Wi-Fi 6 working in the stadium was the same week Apple started delivery of its new iPhone 11 line, which includes support for the new Wi-Fi 6 standard. After seeing 941 devices connect on Wi-Fi 6 at the Texas Tech game, Payne said Oklahoma saw a steady increase of Wi-Fi 6 devices at each following home game, with 1,471 at the West Virginia game and 2,170 at the Iowa State game.

Is AX coming ‘sooner’… rather than later?

Though most consumer handsets being used today do not support the Wi-Fi 6 standards, Apple’s decision to include Wi-Fi 6 support in its latest iPhone 11 line as well as Wi-Fi 6 support from other new Android phone models suggests that device support for the standard may be coming sooner, rather than later, to the fans in the stands. When that happens and the Wi-Fi 6 network starts utilizing its new capabilities, Oklahoma’s network will be among the first to make use of the new standard’s ability to support more clients at higher connection speeds, critical features for big networks in small places like football stadiums.

The non-insignificant number of AX devices already seen by the stadium network, Payne said, felt like good justification of the school’s decision to commit to Wi-Fi 6. What was also interesting to Payne was some later analysis of the network which showed Wi-Fi 6 clients using nearly 10 times the data per client as older Wi-Fi 5 devices.

Looking ahead to next season, Payne said he will be working with school network officials to see how to more closely tie the stadium network with the overall campus wireless infrastructure, and to see how the school might be able to incorporate a stadium app or web-based sites to increase the ability of the network to improve the fan experience. Currently Oklahoma uses a portal from AmpThink to get email addresses from network guests, which Payne said will be used by marketing and ticketing departments to try to increase engagement.

The good news is, Payne said, is that “we are no longer looking at what it costs to put a network in place” to drive any new digital experience ideas.

For Oklahoma athletics director Joe Castiglione, it was important for the school to deliver an amenity that provided a a consistent fan experience whether a fan was in a suite or in the upper deck, a goal our tests seem to have validated.

“We feel that the Oklahoma tradition is among the strongest in the nation and really want to provide a top-notch fan experience to celebrate that tradition,” Castiglione said. “Wi-Fi is just the beginning of enhancing that experience. We hope to be able to use it to engage our fans through in venue activations and experiences that would not be available without the addition of Wi-Fi.”
