Bird of a different feather: Atlanta’s Mercedes-Benz Stadium takes tech in a new direction

As you walk up to it, the striking angular architecture of Atlanta’s Mercedes-Benz Stadium is a way of telling you, before you even set foot inside, that this building is different from any other stadium you may know. When you get inside, see the eight-petal roof and the circular video “halo board” right below it, those feelings are confirmed.

Deeper inside the venue’s construction, the theme is continued with the building’s network technology, which is similarly different if less easily seen. With more fiber optical cabling than perhaps any comparable stadium, the new home of the NFL’s Atlanta Falcons is built more with an eye toward what comes next, while also debuting with systems built with the peak of current knowledge and deployment designs.

Unlike the owners and operators of some other new arenas, the Falcons’ aren’t wasting much bandwidth trying to paint Mercedes-Benz Stadium as the best-ever when it comes to stadium technology. (In fact the stadium network crew is being very closed-mouth about everything, not providing any game-day statistics even though informed rumors tell us that the Wi-Fi network is doing very well.) But come back in 5 years, or even 10 years from now, and see if the decisions made here were able to consistently keep the Falcons’ new roost at the top of the stadium-technology game.

Table stakes, plus a halo board

Inside the Falcons’ new roost, with the halo board and roof visible

What’s working now, as the venue enters the Falcons’ 2017 NFL season, includes a Wi-Fi network built with nearly 1,800 Aruba access points. Of the 1,000 of those installed in the main seating bowl, most are mounted underneath the seats, a trend that gained steam a couple years ago and now has numerous proof points behind the higher capacity and faster performance of so-called “proximate” networks. There’s also a neutral-host distributed antenna system, or DAS, for enhanced cellular coverage, built and owned by the arena with space rented out to all four of the major U.S. cellular carriers.

And then there’s the halo board, the circular or oval-shaped video screen that circumnavigates the roof right at the base of the also-innovative eight-petal roof, which is designed to open or close in seven minutes or less. If big video screens are a never-ending trend the Falcons are right out in front with their offerings at Mercedes-Benz Stadium, starting with the halo board and the “mega-column,” a hundred-foot high vertical screen just inside the main entryway. The 2,000-plus other regular-sized screens scattered around the venue should ensure there’s always a display visible, no matter where guests are looking.

And while the team has future plans for video, the one piece of network technology that may matter most is the optical fiber, which can support wider bandwidth and faster speeds than traditional copper cabling. The statistic thrown around often in the Mercedes-Benz Stadium press materials — nearly 4,000 miles of fiber used — is meaningless to most who repeat it, other than it seems like a lot of glass wiring.

What’s more interesting from a stadium-design perspective is not exactly the total but instead the reach of the fiber, as the network designers pushed fiber out to the edges much further than before, betting that by putting more capacity farther into the reaches of the stadium, there will be less needs for big-time network upgrades in the future, when the inevitable need for more bandwidth arrives.

Under-seat Wi-Fi AP

“We like to say we’re future flexible, not future proof,” said Jared Miller, chief digital officer for the Falcons. “Future proof does not exist in technology.”

Informed by Texas A&M

In picking IBM as its lead networking technology partner, the Falcons most certainly gleaned a lot of their stadium network design lessons from the 2015 deployment of a new Wi-Fi network at Texas A&M’s Kyle Field, a project also led by IBM. Making deep use of Corning fiber networking technology, A&M’s Wi-Fi network hit the ground running hard, as a big number of under-seat APs supported several big days of data use by the 100,000-plus Aggie fans who filled the building on home-game weekends.

The basic idea behind using fiber is that optical cabling can carry far more bandwidth at faster speeds than a comparable copper wire. By putting more fiber farther out into all reaches of a stadium, a network can be “future proofed” by being able to support many more new devices on the end of each fiber strand. By not having to string new cabling everywhere to support greater demand, a stadium will theoretically spend far less money in the long haul.

Wi-Fi and DAS will have the bathroom lines covered

From a network backbone perspective, the Falcons took what Texas A&M did and pushed even farther with fiber, taking the glass circuits as close to the edge devices (mainly Wi-Fi APs) as possible. In our mid-August press tour at Mercedes-Benz Stadium, we saw many of the so-called “mini-IDFs,” small closets with three or four pieces of gear in them, mounted on walls throughout the stadium.

“We kept the use of copper as short as possible,” said Miller. “With bandwidth demands continuing to grow at an exponential rate, we need to make sure we keep pace with rapidly evolving technology.”

If there is one big drawback to using fiber, it has to do with the intricacies of dealing with the construction end of building fiber networks, since the cables need to be precisely cut and joined, often with highly specialized equipment. There are also far more network technicians who are trained in copper wiring deployments than in fiber, so personnel issues can also increase costs and complexity.

On the eve of the Falcons’ first regular-season home game, a mid-September playoff rematch with the Green Bay Packers, Miller and his crew had not yet provided any traffic or network throughput statistics from the preseason games at Mercedes-Benz Stadium. However, some inside sources told MSR that the Wi-Fi traffic during the preseason and the early September college game was at the top range of what has been historically seen for NFL game days, so it appears that the system is ready to go.

Holding off on more bells and whistles

Though it may be hard for any other stadium to top the halo board for a while, on some other technology-related items the Falcons and Mercedes-Benz Stadium are taking a step back and not pushing digital solutions to where they might not be needed.

One of the many ‘mini-ISFs,’ this one in the press box

On the stadium app side, for instance, the IBM-developed application does not support some services seen at other NFL or pro-league stadiums, like “blue dot” wayfinding or in-seat food delivery or even express pickup for concessions. Instead, the app uses wayfinding based on static maps, where you need to put in both a location and a desired destination; and on the food-ordering side, fans can enter in an order and their credit card information, but must then take it to a stand to be scanned and fulfilled.

And while the Falcons’ new app does have a fun FAQ chatbot called “Ask Arthur” (for the team’s owner, Arthur Blank), there won’t be any live instant replay features in the app. With all the video screens in the stadium, the Falcons think they have the replay angle thing covered. The Falcons will use the app, however, for expanded digital-ticketing features as well as to help fans find and pay for parking. On the concessions side, the Falcons’ well-reported “fan friendly” pricing with low costs for most stadium food staples might prove more interesting to fans than being able to have food delivered.

Miller was also adamant that fans won’t see any portal or other marketing messages between finding and connecting to the Wi-Fi network.

“You just join ‘AT&Twifi’ and you’re on,” Miller said. “You’re a guest in our house. The last thing we want to do is slow you down from getting on the network.”

Iowa’s Kinnick Stadium gets new DAS for 2017

Fans at the University of Iowa’s Kinnick Stadium should finally have cellular connectivity this season, thanks to a new neutral-host DAS installed by Connectivity Wireless Solutions over the past offseason.

Though we don’t have any stats or speed test reports yet, Connectivity Wireless said the DAS was scheduled to begin operation at the start of the season, with fine-tuning taking place during the first few home games. Verizon Wireless and U.S. Cellular were active on the DAS at the start, according to Connectivity Wireless, with AT&T in testing at the season’s start.

Steven Morris, director of engineering for Connectivity Wireless, said the new DAS is using Corning One gear at the core, and has a mainly fiber infrastructure with coax used only in the “final 30 to 40 feet” for connection to edge gear and antennas. Connectivity Wireless also installed a new DAS at the school’s basketball stadium, Carver-Hawkeye Arena, which should also be ready for the upcoming season. According to news reports, the DAS contract for Kinnick is $6 million, while the cost for the network at Carver-Hawkeye is $3 million.

The DAS for the 70,000-seat historic Kinnick Stadium, Morris said, has 13 sectors, and according to news reports, uses approximately 200 antennas. Like many older open-bowl stadiums, deployment at Kinnick was a challenge simply due to its design as well as to the fact the building has historical aesthetic elements, making antenna placement a job with multiple approvals necessary.

Overcoming aesthetic and design challenges

“There was no real place for antennas,” said Morris, who said Connectivity Wireless found a way to bring coverage to the main bowl seating partially through a strategy of replacing existing flagpoles mounted around the stadium’s edges with new custom-designed poles that had conduit and antenna mounts built in.

“It was a big challenge for us, with lots of approvals to go through,” said Morris. Connectivity Wireless also had to trench fiber from the stadium to the campus’ network head-end, which is located in one of the school’s hospitals about a mile away from Kinnick. All this work needed to be done in the spring and summer, Morris said, since you can’t dig underground in Iowa where winter weather can regularly produce sub-zero temperatures.

With plenty of fiber capacity now in place, Morris said Kinnick Stadium could also eventually install a Wi-Fi network, though it would most likely mean some kind of under-seat AP deployment with its associated coring costs. However, there still may be some legal entanglements regarding any future network deployments, as Iowa is still involved in a lawsuit with American Tower, which it had originally contracted with to build the Kinnick DAS. That 2013 deal, however, was terminated by the university in 2015, and the matter is still being adjucated under a lawsuit filed by American Tower. American Tower would not comment on the status of the lawsuit.

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

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

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

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

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

Under-seat coverage impressive

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

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

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

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

Light standards and beer gardens

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

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

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

Denver Broncos, Verizon bring Wi-Fi blitz to Sports Authority Field at Mile High

Even as the team on the field seeks to regain its recent Super Bowl champion status, Denver Broncos fans will have something they can all cheer this season — vastly improved Wi-Fi networking service, which is now available to all fans and not just Verizon Wireless customers.

Even though we found good connectivity on our last visit to Sports Authority Field at Mile High two seasons ago, the caveat was that Wi-Fi was only available to Verizon customers, since the carrier couldn’t find another wireless provider who would chip in to fund the system. Fast-forward to later in 2016, when Verizon and the Broncos sought to upgrade the entire system and ended up picking a $6 million bid from Cisco to install a total of 1,470 new Wi-Fi APs, replacing the 640 APs in the old system, which started out with 500 Cisco APs in 2011 and added some more over the years.

The new network, which is scheduled to be fully completed by late October or early November this year, is already live in parts of the lower bowl at Mile High as well as in many concourse, suite and back-of-house locations. The big difference inside the hardware is the Broncos’ and Verizon’s choice of using the new Cisco 3800 APs, which can have two separate antennas in each device, basically doubling the amount of connectivity per unit. The new network will be powered by a new 10-gig backbone pipe provided by CenturyLink, replacing the 1-Gbps pipe that was previously used.

Cisco 3800s are proving to be a popular choice in venues lately, being picked for recent deployments at the San Jose Sharks’ SAP Center and at Notre Dame Stadium.

“The 3800 is a game-changer,” said Russ Trainor, the Broncos’ vice president of information technology, during a stadium tour Tuesday, citing its ability to connect more fans per device. Perhaps the most visually striking note of the upgrade is the huge amount of new railing-mounted APs in the building, with several per row not an uncommon sight in the lower bowl. Jason Moore, a senior IT engineer with the Broncos (and as Trainor calls him, a “Wi-Fi wizard”) said the enclosures are all custom designs from a local provider, with some of the fiberglass structures housing not just Wi-Fi but Verizon DAS antennas as well.

(Right now, the DAS situation at Mile High remains unchanged from our last visit, with all cellular carriers basically running their own operations.)

Going under-seat in bright orange fashion

The other new deployment method being used by the Broncos is under-seat placement, a tactic used for about 90 APs so far, half of those in the South end zone seats, where there are no overhead structures at all. Overhead AP placements are also being used in the main seating bowl, mainly to serve rows at the tops of sections.

No mistaking where the under-seat APs are at Broncos games.

Unlike other stadiums, who try to hide the under-seat APs as best they can, the Broncos have gone the opposite direction, painting many a bright Broncos orange to show up under the Broncos blue seats. “The mounting options are just about getting the APs as close to fans as we can,” Moore said. “Railing [mounts] work great. Under seat is new to us, and we’re excited to see how they work.”

In a quick empty-stadium test, MSR found Wi-Fi speeds in the south stands of 46 Mbps download and 47 Mbps up, on both the all-access and Verizon-customer SSIDs. In section 309, right at the 50-yard line, we got a Wi-Fi speed reading of 69 Mbps down, 75 Mbps up. Verizon execs at the tour said that like at other NFL stadiums where Verizon helps provide the Wi-Fi, Verizon customers will have reserved bandwidth and an autoconnect feature that links them to Wi-Fi without any sign-in needed. Trainor said the Broncos are still undecided how to approach the all-access Wi-Fi onboarding, though the team is leaning in the favor of having some kind of portal approach to gather information from fans using the service.

Of the 1,470 planned new APs (that count may change as final tuning is made, Moore said), the Broncos plan to deploy 920 of those in the seating bowl. With many of those devices having two 5 GHz antennas for each AP, the Sports Authority Field at Mile High crowds should enjoy one of the league’s top network experiences when all the work is completed.

Both railing and under-seat deployments are used to bring Wi-Fi to the south stands.

Those readers who closely track MSR stories for such stats should know that we are now working on a new chart to show not just the top numbers of APs in stadiums, but actual radios and antennas thanks to devices like the Cisco 3800 that have more than one per unit. (Any and all help with such counts is appreciated, you know where to find us!)

Like other stadiums, the network in the bowl at Sports Authority Field at Mile High will switch to only 5 GHz connections when complete. Even a few years ago, stadiums needed to still support 2.4 GHz Wi-Fi connections for fans, but the quick shift in consumer devices has shown that almost all mobile devices used these days have a 5 GHz radio.

A string of summer concerts at the stadium (which still bears the name of the now-bankupt and closed sporting-goods business as the Broncos search for a new title sponsor) kept the network deployment from being completed sooner, but Trainor and Moore said the incremental improvements are already being noticed. With both the old system and new system working simultaneously, Moore said that at last week’s college game between the University of Colorado and Colorado State University, the network saw approximately 35,000 unique users — more than the typical 25,000 unique connections during a Broncos game when only Verizon customers could use the network.

“Our goal and challenge is to connect as many fans as possible,” Moore said.
