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!

(If you need to catch up, here is part 1 of this missive)

Sunday, April 7: Geeking out on Wi-Fi 6

If Saturday had been all about walking around, my Final Four Sunday was all about staying in. But the day of relative inaction on the basketball court played right into my strategy for the weekend, which was: Find a way to maximize my four days in Minneapolis to get the most work done possible.

Sunday, that meant I was all in with the AmpThink team, basically on two levels. One, I wanted to get a real in-depth look at the temporary Wi-Fi network the company had installed at U.S. Bank Stadium to cover the seats that weren’t part of the stadium’s usual football configuration. For the Final Four, that mean extra seats along the courtside “sidelines” that actually were erected over the lower-bowl football seats and then extended out to the edge of the hardwood floor, as well as all the temporary seats in each end zone that stretched the same way out to the basketball court.

After a “team breakfast” at a great breakfast-diner kind of place the AmpThink team and I got inside the arena in a break between practices (you are not allowed near the court when practices are going on) and I got an up-close look at how AmpThink stretched the network from the football configuration out to the temporary Final Four floor. Though AmpThink covered most of the bowl seating at U.S. Bank Stadium with innovative railing-mounted antenna enclosures (which Verizon copied when it added DAS capacity ahead of Super Bowl 52, which was held in the stadium the year before), for the temporary seating AmpThink went with an under-seat design, with AP boxes located under the folding chairs and switches located underneath the risers.

The temporary network, as it turned out, worked very well, but the funniest story to come out of the deployment was one of theft — after Saturday’s games the network analysis showed one of the APs offline. Further exploration by the AmpThink team found that the AP itself was no longer around — some net-head fan had apparently discovered that the under-seat enclosures were not secured, and for some reason thought that a Cisco Wi-Fi AP would make for a fine Final Four gift to take home. My guess is that future temporary networks might see some zip-ties used to lock things down.

After a cool tour underneath the temporary stands to see how AmpThink wired things, we spent the better part of the afternoon hanging out and talking about Wi-Fi 6, a topic the AmpThink brain trust was well wired on. Eventually that day of brainstorming, interviewing and collaboration led to the joint AmpThink/MSR Wi-Fi 6 Research Report, which of course you may download for free.

It was the best use possible I could think of for the “day off” Sunday, where if you are involved with the Final Four you are basically waiting around until Monday night. And since the AmpThink team is rarely ever in one place together for a full day — later that year, for example, AmpThink would be busy deploying new networks at Ohio State, Oklahoma, Arkansas and Dickies Arena — it was an extremely cool opportunity to be able to spend time tapping the knowledge of AmpThink president Bill Anderson and his top lieutenants.

Still feeling the physical effects of my Saturday — and knowing Monday would be even more taxing — I headed back to the hotel in the late afternoon, catching the end of the women’s Final Four at the second of the two local brewpubs next to the Marriott. Though the championship game wouldn’t take place until Monday evening, I had an early start ahead to a long day of again, maximizing those stories.

Monday, April 8: Allianz Field, the Mall of America, and the championship game

Every quarter, Mobile Sports Report tries to find a good mix of profiles to educate its readership. Typically we try to keep the profiles in season, for relevance and timing. But other times, you just go get a good story because it’s interesting. Or, if you can, you do multiple stories on one plane ticket, something that speaks to the bottom line of being an entrepreneurial startup that has to keep an eye on the budget.

So while other “media” at the Final Four may have been taking late breakfasts or hitting the gym Monday morning, I was in an Uber out to Allianz Field, the new home of the MLS Minnesota United. Though it wasn’t scheduled to open until later in April, the folks behind the networking technology — a local company called Atomic Data — had agreed to give MSR a look-around at the Wi-Fi deployment, a great opportunity we couldn’t pass up.

Yagya Mahadevan, enterprise project manager for Atomic Data and sort of the live-in maestro for the network at Allianz Field, met us at the entry gate and gave us the full stadium walk-around, which was great to have, bad hip issues be damned. I really liked the tour and being able to write the story about how Atomic Data got its feet in the door at a major professional venue, and hope the company can do the same for other venues in the future. I’m also hoping to get back to Allianz Field for a live game when such things start happening again, because the place just looks sharp and I am kind of all in on the way MLS teams are tapping into the fan experience without charging hundreds of dollars a seat like some other pro leagues in the U.S.

After an hour or so of touring Allianz Field it was back in another Uber to the Mall of America, where I had scheduled an interview with Janette Smrcka, then the information technology director for the Mall. (Janette is now part of the technology team at SoFi Stadium, and we hope to have more talks with her soon!) Janette, who I had gotten to know while reporting on the Wi-Fi deployment at the Mall of America, had told me about a cool new project involving wayfinding directories at the Mall, a story which fit perfectly with the new Venue Display Report series we were launching last year.

After sitting down with Janette to get the specifics on the display gear I went into the Mall itself and wandered around for a while (OK, I also did stop to get a chocolate shake at the Shake Shack) watching people use the directories. My unscientific survey showed that people used them quite a bit, with all the design elements Janette and her team coming into play, like deducing that people would be more willing to use smaller-sized displays since they could shield them with their bodies, making the interaction more private. Little things do matter in technology, and it’s not always the technology that matters.

In the mall you couldn’t forget what was going on that weekend — as if the fans wandering around in their school gear would let you. I jumped back on the light rail to get back to the hotel and had my media-celebrity moment heading up to my room, when John Feinstein himself held the door to the elevator so I could get there in time.

Wi-Fi, hoops and a brat and a beer

As soon as I got to the stadium on the press bus I skipped the whole press working-room thing and headed up to the football press box to secure a spot. Turns out I didn’t need to worry as most of the media still either wanted to be closer to the court or closer to the workroom to get their stories done on deadline. Fine for all us. By now I had completely learned all the elevator and escalator pathways I needed to know to get around the stadium in record time. I took Wi-Fi speedtests, I took DAS speedtests, I watched the crowd get into the excitement of being at the “big game.”

Some Final Four fans using directories at the Mall of America.

For sure, part of the fun of attending bucket-list events these days is tied to the mobile device. A big part of the fun. I watched many, many people take pictures of themselves and their companions, take pictures or videos of the action on the court, or just (in some cases) walk around with their phones on video broadcast, relaying the live scene to an audience of who knows who. To me that’s one of the main points of these networks our industry sets up and runs — enabling those who are lucky enough to be there live to be able to share that experience, somewhat instantly, with those closest to them (or their imagined wider audiences).

Though these stadium visits can sometimes be lonely and somewhat strange — I mean, who’s there to cheer for the Wi-Fi? — at the Final Four I considered myself part of the general audience, a witness to the fun and excitement of “being there.” And by halftime I had already done all the “work” I needed to do — the Wi-Fi was strong, as was the DAS — so I camped out in the press box and waited for the second half to begin, so I could go out and get the bratwurst and beer I felt I’d earned.

It took a little bit of walking around to find the stands I wanted to hit — I wanted a beverage that was local, not national, and a brat done right — and I found both somewhat fortunately close to the press box. I took my bounty to a stand-up counter space located just off the main upper concourse and for the time of my meal I was just another hoops fan, enjoying the close contest between Virginia and Texas Tech. Then it was back to the press box and more just-fan watching, an exciting finish and then trying to capture the perfect “confetti burst” photo for the cover of our upcoming issue.

After goodbyes to David and his crew and the AmpThink team, since I didn’t have any stories to write I was on the first press bus back to the hotel, where I quickly crashed ahead of my flight back home Tuesday morning. It was a long weekend in Minneapolis and my hip hurt, but I had done what I needed to do, notebook full of stories that I could write while I recovered from the upcoming surgery.

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!

Temporary courtside network helps set Final Four Wi-Fi records

One of the traditional characteristics of the Final Four is the yearly travel scramble of the fortunate fans and teams who have advanced to the championship weekend. Somehow, with only a week’s notice, plane flights, road trips and hotel rooms get scheduled and booked, leading to packed houses at college basketball’s biggest event.

On the stadium technology side, a similar last-minute fire drill happens just about every year as well, as the hosting venues reconfigure themselves to host basketball games inside cavernous buildings built mainly to hold football crowds. At this year’s NCAA Men’s Final Four at U.S. Bank Stadium in Minneapolis, the stadium tech team and partner AmpThink were able to quickly construct a temporary Wi-Fi network to cover the additional lower-bowl seating. The new capactity was part of a record-setting Wi-Fi network performance at the venue, with single-day numbers surpassing those from Super Bowl 52, held in the same building the year before.

The Wi-Fi numbers, both staggering and sobering especially to venues who are next in line for such bucket-list events, totaled 31.2 terabytes for the two days of game action, according to figures provided by the NCAA. For the semifinal games on Saturday April 6, U.S. Bank Stadium’s Wi-Fi network saw 17.8 TB of traffic, topping the 16.31 TB used during Super Bowl 52 on Feb. 4, 2018. The Saturday semifinals also set an attendance record for the venue, with 72,711 on hand, topping the 67,612 in attendance for Super Bowl 52.

During the championship game on April 8, U.S. Bank Stadium saw an additional 13.4 TB of data used on the Wi-Fi network, giving the venue three of the top four single-day Wi-Fi numbers we’ve reported, with this year’s mark of 24.05 TB at Super Bowl 53 in Atlanta the only bigger number. Saturday’s take rate at U.S. Bank Stadium, however, surpassed even the most-recent Super Bowl, with 51,227 unique users on the network, a 70 percent take rate.

‘Like building an arena network inside a football stadium’

Editor’s note: This report is from our latest STADIUM TECH REPORT, an in-depth look at successful deployments of stadium technology. Included with this report is a profile of the new Wi-Fi network at Allianz Field in St. Paul, Minn., and an in-depth research report on the new Wi-Fi 6 standard! DOWNLOAD YOUR FREE COPY now!

Switches for the temporary network were deployed under the seat scaffolding.

There’s no doubt that the temporary network installed by AmpThink and the U.S. Bank Stadium IT team contributed a great deal to the final Wi-Fi totals, with 250 access points installed in the additional seats. Like at other football venues that are transformed into basketball arenas, U.S. Bank Stadium had temporary seating installed on all four sides of the stadium, with temporary risers stretching down over football seating as well as with risers built behind both baskets. More seats were installed on the “floor” of the football field, right up to the elevated court set in the middle. The temporary APs, like the existing ones in the stadium, are from Cisco.

“There are a lot more moving parts to a Final Four than to a Super Bowl,” said David Kingsbury, director of IT for U.S. Bank Stadium, describing the difference in providing the networking and technical underpinnings for each event. While planning for the networks was obviously done far in advance, the actual buildout of the temporary Wi-Fi couldn’t even begin until the additional seating was in place, a task that finished just five days before the first game was played.

That’s when AmpThink deployed a staff of 12 workers to start connecting cables to APs and to switches, while also adding in another 700 wired network connections to the courtside areas for media internet and TV monitor connections. Like it does for every venue network it designs and deploys, AmpThink came to the stadium equipped with a wide assortment of lengths of pre-terminated cables, preparation that made the fast deployment possible.

“If we had to spin raw cable and terminate it on site, we never would have been able to finish in five days,” said AmpThink president Bill Anderson.

AmpThink’s previous experience in deploying such temporary networks under temporary seating — including at the previous year’s Final Four in San Antonio — taught the company that it would also need protection for under-seat switch deployments, to fend off the inevitable liquid spills from the seats above. That requirement was potentially even more necessary at U.S. Bank Stadium, since this year’s Final Four was the first to allow in-venue sales of alcoholic beverages.

Some temporary seats were deployed on top of existing lower bowl seats.

With some of the temporary seating installed over existing seating, there were 95 APs in the existing handrail-enclosure design that had to be turned off for the Final Four, according to Kingsbury. The 250 new APs added were all installed under the folding chairs, in enclosures that simply sat on the floor.

According to AmpThink’s Anderson, the company did learn a lesson at U.S. Bank Stadium — that it will, at future events, need to secure the actual enclosures since during the weekend curious fans opened a few of the boxes, with one AP disappearing, perhaps as an interesting IT souvenir.

In San Antonio, AmpThink had zip-tied the enclosures to chairs, which led to increased labor to detatch the devices during the post-event breakdown. While having no such measures at U.S. Bank led to a fast removal — AmpThink said it had removed all the temporary network elements just seven hours after the championship game confetti had settled — for next year’s Final Four AmpThink plans to at least zip-tie the enclosures shut so that fans can’t attempt any ad hoc network administration.

More APs for back of house operations

Another difference between the Final Four and the Super Bowl is the fact that four, not two, teams are in attendance for a full weekend, necessitating the need to set up temporary “work rooms” adjacent to each school’s locker room area. The media work center for the Final Four is also typically larger than that of a Super Bowl, again with more cities and their attendant media outlets on site thanks to there being four, not just two, teams involved.

A concourse speed test taken just after halftime of the final game.

“We had to cover a lot of places in the stadium that we don’t normally cover” with wireless and wired network access, Kingsbury said, saying that an additional 30 APs were needed for team rooms and the main media workspace, which were located on the field level of the stadium in the back hallways. An interesting note at U.S. Bank Stadium was that the yards and yards of fabric used as curtains to cover the clear-plastic roofing and wall areas was actually benefical to Wi-Fi operations, since it cut off some of the reflective interference caused by ETFE surfaces.

According to Kingsbury the final count of active APs for the Final Four was 1,414, a number reached by adding in the temporary APs while deducting the ones taken offline. Not included in the official NCAA traffic numbers was an additional 3 TB of traffic seen during the free-admission Friday practice sessions, when 36,000 fans visited the stadium, with 9,000 joining the Wi-Fi network.

From the official stats, the peak concurrent user number from Final Four Saturday of 31,141 was also an overall record, beating Super Bowl 53’s mark of 30,605. (Super Bowl 53 had 70,081 fans in attendance for the Feb. 3 game between the New England Patriots and the Los Angeles Rams.) The Wi-Fi network numbers for Monday’s championship game (won by Virginia 85-77 over Texas Tech in overtime) saw big numbers itself, with 13.4 TB of total data used, and 48,449 unique connections and 29,487 peak concurrent users (out of 72,062 in attendance). Monday’s game also produced a peak throughput number of 11.2 Gbps just after the game ended.

None of those totals could have been reached without the temporary network, which AmpThink’s Anderson compared to “building a 10,000-seat arena network inside a football stadium.” Next stop for a temporary Wi-Fi network is Mercedes-Benz Stadium in Atlanta, where the 2020 Final Four awaits.

This is what your football stadium looks like with a championship basketball game inside of it.

In addition to the big Wi-Fi numbers seen at the NCAA men’s 2019 basketball championship game, AT&T said it saw 2.5 terabytes of data used by its customers on its DAS network at U.S. Bank Stadium in Minneapolis for the final game of the men’s Final Four weekend.

The neutral-host DAS in U.S. Bank Stadium, which is operated by Verizon, tested strong during MSR’s visit to the Final Four — we saw a mark of 37.5 Mbps on the download and 45.0 Mbps on the upload during the championship game, on a Verizon phone. Verizon, however, declined to provide any data totals from the Final Four.

In addition to its championship game numbers, AT&T said it saw 44.6 TB of data used on its networks in and around U.S. Bank Stadium for the entire men’s Final Four weekend.

Women’s Final Four sees 1.1 TB of DAS

At the NCAA women’s Final Four weekend in Tampa, Fla., AT&T said it saw a total of 1.1 TB of traffic used by its customers on the new MatSing Ball-powered DAS at Amalie Arena. That number includes traffic from both semifinal games as well as the championship game on April 7.

Second news item: Final Four weekend sees 31.2 terabytes of Wi-Fi data used.

Even as people across the wireless industry seem ready to dig Wi-Fi’s grave, the view from here is not only is Wi-Fi’s imminent death greatly exaggerated, things may actually be heading in the other direction — Wi-Fi’s last-mile and in-building dominance may just be getting started.

The latest ironic put-down of Wi-Fi came in a recent Wall Street Journal article with the headline of “Cellphone Carriers Envision World Without Wi-Fi,” in which a Verizon executive calls Wi-Fi “rubbish.” While the article itself presents a great amount of facts about why Wi-Fi is already the dominant last-mile wireless carrier (and may just get stronger going forward) the article doesn’t talk at all about the Super Bowl, where Verizon itself basically turned to Wi-Fi to make sure fans at the big game who were Verizon customers could stay connected.

As readers of MSR know, the performance of the cellular DAS at Mercedes-Benz Stadium in Atlanta has been a question mark since its inception, and the emergence of competing lawsuits between lead contractor IBM and supplier Corning over its implementation means we may never learn publicly what really happened, and whether or not it was ever fixed. Though stadium tech execs and the NFL said publicly that the DAS was fine for the Super Bowl, Verizon’s actions perhaps spoke much louder — the carrier basically paid extra to secure part of the Wi-Fi network bandwidth for its own customers, and used autoconnect to get as many of its subscribers as it could onto the Wi-Fi network.

While we did learn the Wi-Fi statistics in detail — thanks to the fact that Wi-Fi numbers are controlled by the venue, not the carriers — it’s interesting to note that none of the four top cellular providers in the U.S. would give MSR a figure of how much cellular traffic they each saw in the stadium on Super Sunday. For the record, stadium officials said they saw 12.1 TB of data used on the Mercedes-Benz Stadium DAS on Super Bowl Sunday, a figure that represents the total traffic from all four carriers combined. But how that pie was split up will likely forever remain a mystery.

AT&T did provide a figure of 23.5 TB for Super Bowl traffic inside the venue as well as in a 2-mile radius around the stadium, and Sprint provided a figure (25 TB) but put even a less-measurable geographic boundary on it, meaning Sprint could have basically been reporting all traffic it saw anywhere inside the greater Atlanta city limits. Verizon and T-Mobile, meanwhile, both refused to report any Super Bowl cellular statistics at all.

Verizon also did not reply to a question about how much traffic it saw on the Verizon-specific Wi-Fi SSID inside the venue. While we get the marketing reasons for not reporting disappointing stats (why willingly report numbers that make you look bad?), it seems disingenious at best for one Verizon executive (Ronan Dunne, executive vice president and president of Verizon Wireless) to call Wi-Fi “rubbish” when another part of the company is relying heavily on that same rubbish technology to make sure its customers can stay connected when the cellular network can’t keep up. One man’s trash, I guess, is another division’s treasure.

Wi-Fi 6 and more spectrum on the way

For venue owners and operators, the next few years are likely going to be filled with plenty of misinformation regarding the future of wireless. The big carriers, who pull in billions each quarter in revenue, are staking their near-term future on 5G, a label for a confusing mix of technologies and spectrum chunks that is unlikely to be cleared up anytime soon. Unlike the celluar industry change from 3G to 4G — a relatively straightforward progression to a new and unified type of technology — the change to 5G has already seen carriers willing to slap the marketing label on a different number of implementations, which bodes many headaches ahead for those in the venue space who have to figure out what will work best for their buildings and open spaces.

There’s also the imminent emergence of networks that will use the CBRS spectrum at 3.5 GHz, which will support communications using the same LTE technology used for 4G cellular. Though CBRS has its own challenges and hurdles to implementation, because it is backed by carriers and the carrier equipment-supply ecosystem, you can expect a blitz of 5G-type marketing to fuel its hype, with poor old Wi-Fi often the target for replacement.

While the Wi-Fi Alliance and other industry groups rallying around Wi-Fi might seem like the Rebel Alliance against a First Order dreadnought, if I’ve learned anything in my career of technology reporting it’s that you should never bet against open standards. I’ve been around long enough to see seemingly invincible empires based on proprietary schemes collapse and disappear under the relentless power of open systems and standards — like Ethernet vs. DEC or IBM networking protocols, and TCP/IP vs. Novell — to count out Wi-Fi in a battle, even against the cellular giants. In fact, with the improvements that are part of Wi-Fi 6 — known also as 802.11ax in the former parlance — Wi-Fi is supposed to eventually become more like LTE, with more secure connections and a better ability to support a roaming connection and the ability to connect more clients per access point. What happens then if LTE’s advantages go away?

With Wi-Fi 6 gear only now starting to arrive in the marketplace, proof still needs to be found that such claims can work in the real world, especially in the demanding and special-case world of wireless inside venues. But the same hurdles (and maybe even more) exist for CBRS and 5G technologies, with big unanswered questions about device support and the need for numerous amounts of antennas that are usually ignored in the “5G will take over the world soon” hype stories. I’d also add to that mix my wonder about where the time and talent will come from to install a whole bunch of new technologies that will require new learning curves; meanwhile, as far as I can tell the companies supporting Wi-Fi continue to add technology pros at ever-growing user and education conferences.

So as we ready for the inevitable challenge of sifting through cellular FUD and hype let’s have a cheer for good old Wi-Fi — for now the champion of the biggest data-demand days in venues, and maybe the leader for years to come.
