News item: Super Bowl 53 sees 24 terabytes of Wi-Fi data used.

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.

Super Bowl recap: 24 TB for Wi-Fi, 12 TB for DAS

Super Bowl 53 at Atlanta’s Mercedes-Benz Stadium rewrote the record book when it comes to single-day stadium Wi-Fi, with 24.05 terabytes of traffic seen on the stadium’s network. That is a huge leap from the official 16.31 TB seen at last year’s Super Bowl 52 in Minneapolis at U.S. Bank Stadium.

According to official statistics provided by Extreme Networks, new high-water marks were set last Sunday in every category of network measurement, including an amazing 48,845 unique users on the network, a take rate of 69 percent out of the 70,081 who were in attendance to watch the New England Patriots beat the Los Angeles Rams 13-3. The average Wi-Fi data use per connected fan also set a new record, with the per-fan mark of 492.3 megabytes per user eclipsing last year’s mark of 407.4.

While fans might have preferred some more scoring excitement during the game, the lack of any tense moments in network operations was a perfect outcome for Danny Branch, chief information officer for AMB Sports & Entertainment.

“I was ecstatic on how [the network] executed, but honestly it was sort of uneventful, since everything went so well,” said Branch in a phone interview the week after the game. Though network performance and fan usage during some of the big events leading up to the Super Bowl had Branch thinking the Wi-Fi total number might creep near the 20-terabyte range, the early network use on game day gave Branch a clue that the final number might be even higher.

“When I saw the initial numbers that said we did 10 [terabytes] before kickoff we didn’t know where it would end,” Branch said. “When we were watching the numbers near the end of the game, we were just laughing.”

Aruba APs and AmpThink design shine

Digital device use once again set records at the NFL’s championship game.

With some 1,800 APs installed inside Mercedes-Benz Stadium — with most of the bowl seating APs located underneath the seats — the Wi-Fi gear from Aruba, a Hewlett Packard Enterprise company, in a design from AmpThink, also saw a peak throughput rate of 13.06 Gbps, seen at halftime. The peak number of concurrent network users, 30,605, also took place during the halftime show, which featured the band Maroon 5 (whose show played to mixed reviews).

Extreme Networks, which provides Wi-Fi analysis in a sponsorship deal with the NFL, had a great list of specific details from the event. Here are some of the top-line stats:

Need proof that people still watch the game? Out of the 24.05 TB total, Extreme said 9.99 TB of the traffic took place before the kickoff, followed by 11.11 TB during the game and halftime, and another 2.95 TB after the game concluded.

On the most-used apps side, Extreme said the most-used social apps were, in order of usage, Facebook, Instagram, Twitter, Snapchat and Bitmoji; on the streaming side, the most-used apps were iTunes, YouTube, Airplay, Spotify and Netflix. The most-used sporting apps by fans at the game were, in order, ESPN, NFL, the Super Bowl LIII Fan Mobile Pass (the official app for the game), CBS Sports (which broadcast the game live) and Bleacher Report.

Did Verizon’s offload spike the total?

While Super Bowl Wi-Fi traffic has grown significantly each year since we started reporting the statistics, one reason for the bigger leap this year may have been due to the fact that Verizon Wireless used its sponsorship relationship with the NFL to acquire its own SSID on the Mercedes-Benz Stadium Wi-Fi network.

Hard copy signage in the stadium helped direct fans to the Wi-Fi.

According to Andrea Caldini, Verizon vice president for networking engineering in the Eastern U.S., Verizon had “autoconnect in play,” which meant that any Verizon customer with Wi-Fi active on their devices would be switched over to Wi-Fi when inside the stadium.

“It’s going to be a good offload for us,” said Caldini in a phone interview ahead of the Super Bowl. While Verizon claimed week to have seen “record cellular traffic” as well during Super Bowl Sunday, a spokesperson said Verizon will no longer release such statistics from the game.

According to Branch, the NFL helped fans find the Wi-Fi network with additional physical signage that was put up just for the Super Bowl, in addition to rotating messages on the digital display screens around the stadium.

“The venue was well signed, we really liked what they [the NFL] did,” Branch said. Branch said the league also promoted the Wi-Fi link throughout the week, with a common ID at all the related Super Bowl activity venues, something that may have helped fans get connected on game day.

No issues with the DAS

One of the parts of the wireless mix at Mercedes-Benz Stadium, the cellular distributed antenna system, was under scrutiny after a lawsuit emerged last fall under which technology supplier IBM sued Corning over what IBM said was faulty installation. While Corning has disputed the claims, over the past year IBM, the Falcons and the NFL all said they got the DAS in working order, and according to Branch “all the carriers were pleased” with its operation during the Super Bowl.

There was only one, but it helped increase the wireless traffic.

According to Branch, the Falcons saw 12.1 TB of traffic on the in-stadium DAS on Super Bowl Sunday, including some traffic that went through the Matsing Ball antennas. Branch said the two Matsing Balls, which hang from the rafters around the Halo Board video screen, were turned back on to assist with wireless traffic on the field during the postgame awards ceremony.

Overall, the record day of Wi-Fi traffic left Branch and his team confident their infrastructure is ready to support the wireless demands of more big events into the future, including next year’s NCAA men’s Final Four.

“Until you’ve taken the car around the track that fast, you don’t really know how it will perform,” Branch said. “But so much work was done beforehand, it’s great to see that it all paid off.”

Extreme Networks, which provides Wi-Fi analysis in a sponsorship deal with the NFL, had a great list of specific details from the event, which you can also peruse in the fine infographic that the company produces after each Super Bowl. Here are some of the top-line stats:

Need proof that people still watch the game? Out of the 24.05 TB total, Extreme said 9.99 TB of the traffic took place before the kickoff, followed by 11.11 TB during the game and halftime, and another 2.95 TB after the game concluded.

As an interesting business note when it comes to sponsorships, the regular Mercedes-Benz Stadium free Wi-Fi SSID, normally ATTWiFi thanks to AT&T’s sponsorship of the network backbone, was switched to #SBWiFi for the big game. Verizon customers were able to connect via a Verizon-specific SSID.

Super Bowl cellular report: AT&T, Sprint combine for almost 50 TB of game-day traffic

Let the cellular traffic reports begin! AT&T is the first to report numbers for our annual unofficial tabulation of wireless traffic from the Super Bowl, with 11.5 terabytes of data in and around Atlanta’s Mercedes-Benz Stadium for Sunday’s Super Bowl 53.

While the New England Patriots’ 13-3 victory over the Los Angeles Rams can and will be debated for its entertainment value (or lack thereof), as usual the fans there for the “bucket list” event apparently held up the trend of mobile wireless traffic continuing to grow. According to AT&T it also saw a total of 23.5 TB of traffic on its network in a 2-mile radius around the stadium Sunday. Both the near-stadium and wider metro numbers were records for AT&T; previously it had seen a high of 9.8 TB of near-stadium traffic at Super Bowl 51 in Houston, and a wider metro total of 21.7 TB last year at Super Bowl 52 in Minneapolis.

Next in with numbers is Sprint, which said it saw 25 TB of traffic “in and around” the stadium on game day, but with Sprint this number is usually the bigger geographical area of the downtown area around the stadium, and not just in and directly outside. Right now Sprint is declining to provide any more granularity on the size of its reporting area “for competitive reasons,” so feel free to speculate if the 25TB comes from network activity actually close to the stadium or if it includes all of downtown Atlanta.

It’s worthwhile to note that Sprint’s reported total grew from 9.7 TB last year to 25 TB this year. So the big-area total is now at 48.5 TB, and that is all the reporting we are going to get this year. A spokesperson from Verizon said that while the company saw “record-breaking” traffic at the event, the spokesperson also said that Verizon “decided to no longer release specific performance statistics around this event.” T-Mobile also declined to provide any traffic figures.

Sprint did have more to say this year about upgrading Atlanta-area infrastructure, adding its massive MIMO technology in an effort to boost performance.

Even without actual numbers from Verizon or T-Mobile it’s clear that last year’s total of 50.2 TB of total metro cellular traffic was most likely surpassed, by a huge margin.

Wi-Fi numbers for Super Bowl 53, reported Friday at 24.05 TB, are an indication that traffic overall is still climbing year to year, with no ceiling in sight.

Going into Sunday’s game there had been some lingering questions about whether or not the Mercedes-Benz Stadium DAS would hold up to the demands, given that its initial deployment is now the subject of a lawsuit between IBM and Corning. As usual, all the wireless carriers said that they had made substantial improvements to infrastructure in the stadium as well as in the surrounding metro Atlanta area ahead of the game, to make sure Super Bowl visitors stayed connected, so for now it seems like any DAS issues were corrected before the game.

An interesting factoid from AT&T: At halftime, AT&T said it saw more than 237 GB of data crossing its network within 15 minutes. Sprint also said that it saw the most data cross its network at halftime. More as we hear more! Any in-person reports welcome as well.

Mercedes-Benz Wi-Fi (and DAS) ready for Super Bowl LIII

With less than two weeks to go before Mercedes-Benz Stadium hosts Super Bowl LIII, there’s no longer any doubt that the venue’s Wi-Fi network should be ready for what is historically the biggest Wi-Fi traffic day of the year.

Oh, and that DAS network you were wondering about? It should be fine too, but more on that later. On a recent game-day visit to the still-new roost of the NFL’s Atlanta Falcons (and the latest MLS champions, Atlanta United), Mobile Sports Report found that the stadium’s Wi-Fi network, using gear from Aruba, a Hewlett-Packard Enterprise company, in a design by AmpThink for lead technology provider IBM, was strong on all levels of the venue, including some hard-to-reach spots in the building’s unique layout.

And in our game-day interview with Danny Branch, chief information officer for AMB Sports & Entertainment, we also finally got some statistics about Wi-Fi performance that should put any Super Bowl capacity fears to rest. According to Branch, Mercedes-Benz Stadium saw 12 terabytes of Wi-Fi used during the College Football Playoff Championship Game on Jan. 8, 2018, the second-highest single-game Wi-Fi total we’ve seen, beaten only by the 16.31 TB recorded at Super Bowl LII on Feb. 4, 2018, at U.S. Bank Stadium in Minneapolis.

“We’re confident, and we’re ready for the Super Bowl,” said Branch about his stadium’s network preparedness, during an interview before the Dec. 2 Falcons home game against the visiting Baltimore Ravens. The night before our talk, Mercedes-Benz Stadium had hosted the SEC Championship Game, where a classic comeback by Alabama netted the Tide a 35-28 win over Georgia, while fans packing the stadium used another 8.06 TB of Wi-Fi data, according to Branch.

Along with lawsuit, DAS gets 700 new antennas

The Wi-Fi totals revealed by Branch were the first such statistics reported by Mercedes-Benz Stadium since its opening in August of 2017. While initially the lack of reports of any kind last fall were thought to have been just some kind of Southern modesty, MSR had been hearing back-channel industry questions about the wireless coverage in the venue since its opening, particularly with the performance of the DAS network.

Those whispers finally became public when IBM filed a lawsuit on Oct. 31 in the U.S. District Court in Atlanta, alleging that subcontractor Corning had failed to deliver a working DAS. In its lawsuit complaints IBM said that the DAS had not worked correctly throughout 2017, and that IBM had to spend large amounts of money to fix it. Corning has since countered with its own legal claims, asking IBM’s claims to be dismissed.

While that battle is now left to the lawyers, inside the stadium, Branch said in December that the DAS was getting its final tuning ahead of the Super Bowl. In addition to (or as part of) the IBM DAS improvements, Branch said that an additional 700 under-seat DAS antennas have been installed in the seating bowl. In our walk-around review during the Falcons’ game, MSR noticed multiple DAS antenna placements that seemed to be new since our last visit in August of 2017, during the stadium’s press day.

“IBM addressed the DAS issues, and we’re in a good place,” said Branch. The NFL’s CIO, Michelle McKenna, also gave her office’s approval of the readiness of the Mercedes-Benz Stadium networks in a separate phone interview. And MSR even got to witness a live opening of the stadium’s unique camera-shutter roof, another technology that ran into some bugs during football season last year but now appears to be solved.

Selfies and speedtests

So how do the networks perform at a live event? The short answer is, on the Wi-Fi side we saw steady speeds wherever we tested, typically in a range between 20 Mbps on the low side to 60+ Mbps on the high side, for both download and upload speeds. On the DAS side, our Verizon network phone saw a wide range of speed results, from some single-digit marks all the way up to 99 Mbps in one location; so perhaps the best answer is that on cellular, your speedtest may vary, but you will most likely always have a strong enough signal to do just about any task you might want to at a stadium, even on Super Sunday. All four major wireless carriers, including Verizon, AT&T, Sprint and T-Mobile, use the Mercedes-Benz Stadium DAS. And you can also expect all the major carriers to beef up local bandwidth with a combination of permanent and temporary upgrades, to ensure good connectivity throughout downtown Atlanta during Super Bowl week. Sprint and AT&T have already made announcements about their local upgrades, and we are sure Verizon and T-Mobile will follow suit with announcements soon.

Though we didn’t get any tests during the brief on-field part of our tour, Branch did point out some Wi-Fi APs on the sidelines for media access. Mercedes-Benz Stadium also now has a pair of MatSing ball antennas perched way up near the roof openings, to help with cellular coverage down to the sidelines.

MSR started our speedtest tour in the place where most Falcons fans probably pull out their phones, in front of the metal falcon structure outside the main entry gate. Even with digital ticketing activities taking place close by and groups of fans taking selfies in front of the bird, we still got a high Wi-Fi test of 35.8 Mbps on the download side and 41.6 Mbps on the upload. On cellular our top speeds in the same area were 3.94 Mbps / 17.2 Mbps.

Just inside the stadium doors from the Falcon is what the team calls the stadium’s “front porch,” an extended concourse with a clear view down to the field. On the Sunday we visited there was a stage with a DJ and rapping crew providing pregame entertainment, in front of two of the stadium’s more distinctive Daktronics digital displays, the 101-foot-tall “Mega Column” and the 26-foot-tall (at its highest point) triangular “Feather Wall” display, which frame part of the porch.

In the middle of a slowly moving crowd that was taking selfies in multiple directions, MSR still got good connectivity, with Wi-Fi speeds of 22.4 Mbps / 12.3 Mbps, and a cellular mark of 5.38 Mbps / 12.0 Mbps. As far as we could see, the wide-open space was being served by antennas mounted on walls on two sides of the opening.

Bridges, nosebleeds and concourses

Looking for some tough-to-cover spots, we next headed to one of the two “sky bridges,” narrow walkways that connect over the main entry on both the 200 and 300 seating levels. Out in the exact middle of the 200-level sky bridge we still got a Wi-Fi test of 14.6 Mbps / 8.19 Mbps; celluar checked in at 4.07 Mbps / 4.59 Mbps.

For some more fan-friendly speeds we wandered in front of the nearby concourse watering hole, the Cutwater Spirits bar, where our Wi-Fi signal tested at 35.8 Mbps / 42.4 Mbps, and the DAS signal (directly in front of an antenna mounted above the concourse) reached 99.2 Mbps / 25.4 Mbps even with heavy foot traffic coming by.

The roof opens at Mercedes-Benz Stadium.

Right before kickoff, we wandered into the top sections of the Falcons’ new roost, where about halfway up in section 310 (near the 50-yard line) we got Wi-Fi speeds of 11.6 Mbps / 1.86 Mbps, and cellular speeds of 13.1 Mbps / 2.50 Mbps, during the height of the on-field pregame festivities. In that section and in others we walked around to, many fans were busy with phones during pregame, with many watching live video.

One interesting technology note: The stadium’s unique Daktronics halo video board, a 58-foot-high screen that circles around underneath the roof, is partially obscured in the uppermost sideline seats. But that’s pretty much the only place you aren’t wowed by the screen’s spectacle, which from most of the rest of the stadium offers multiple-screen views no matter where you are looking up from.

One final speedtest on the 300-level concourse saw the Wi-Fi speeds at 35.8 Mbps / 38.2 Mbps, while another one of those new-looking DAS antennas gave us a speed test of 77.0 Mbps / 21.4 Mbps. During the third quarter we visited the AT&T Perch, a section above the end zone area opposite of the entry porch where there are large displays with multiple TV screens and even some recliner-type chairs where fans can get their other-game viewing on while inside the arena.

Fans are finding the Wi-Fi

Though we haven’t yet seen any more detailed network use statistics, like unique game-day connections or peak concurrent connections for any events, Branch said fans are definitely finding the network. Sponsored by AT&T with an “ATTWifi” SSID, there is no landing page or portal for the network asking for any information — once fans find the network and connect, they’re on.

This type of personal assistance might be even more needed at the Super Bowl.

“In the first year we didn’t promote it [the Wi-Fi] heavily, because we were making sure everything worked well,” Branch said. But this year, he said the team has been promoting the network in emails to season ticket holders, and with video board messages on game days. At a high school football weekend this past fall, Branch said the Falcons saw 75 percent of attendees connect to the Wi-Fi network.

“AmpThink and Aruba did a really good job” on the Wi-Fi network, Branch said. “I love it when my friends tell me how fast the Wi-Fi is.”

By adding solid wireless connectivity to the host of other amenities found inside Mercedes-Benz Stadium — including fan-friendly food and drink prices that are simply the lowest you’ll see anywhere — Branch said he felt like the Falcons’ ownership had succeeded in creating a venue that was “an experience,” where fans would want to come inside instead of tailgating until the last minute.

With the Super Bowl looming on the horizon, Branch knows there’s still no rest until the game is over, with new challenges ahead. The Sunday we visited, the Falcons debuted a new footbridge over the road outside the back-door Gate 1 entry, and Branch knows there will be networking challenges to make sure fans can still connect when the NFL erects its Super Bowl security perimeter far out from the actual stadium doors.

“Our motto is be prepared for anything,” said Branch, noting that there is really no template or historical model for a building unique as Mercedes-Benz Stadium.

“Sometimes it feels like you’re changing tires on a car going 100 miles per hour,” Branch said, only partially in jest. “But we’re confident we’ll be ready for the Super Bowl.”
