Even in the midst of several brand-new stadium debuts and the future-proofed wireless networks inside them, there is a separate, yet distinct trend emerging in the big-stadium, wireless connectivity world: Call it the year of the big upgrade.

Our profile in our latest STADIUM TECH REPORT of Bank of America Stadium in Charlotte, N.C., is a case in point: Thanks to the never-ending demand for more connectivity for fans, stadiums that deployed networks just a few years ago are now finding that those old systems already need upgrades or replacements, typically at a much higher cost than the original network. In addition to BofA Stadium, the New England Patriots’ home, Gillette Stadium, also got a Wi-Fi makeover this past summer, going from about 400 Wi-Fi APs to well over a thousand, with most of the new ones deployed under seats.

According to Fred Kirsch, who oversees the Gillette Stadium network, some of the under-seat placements there were especially tricky, since granite underneath the stands didn’t allow for the ability to drill through the concrete. A workaround involving an above-ground enclosure was envisioned and manufactured, underlining the custom complexity of network deployment found from stadium to stadium. No two are the same, and what works at one may or may not work at another.

But what is common across all these large venues is the ever-increasing need for bandwidth, a moving target that has yet to slow down or stabilize. Last year the story that turned everyone’s head was the need by carriers to upgrade their DAS infrastructure at Levi’s Stadium ahead of Super Bowl 50 – this coming just a year after the stadium had opened for business. While the demands of a Super Bowl (especially Super Bowl 50, which set records for DAS and Wi-Fi usage) are perhaps much different than everyday events, it’s still a safe bet that for many stadiums with Wi-Fi networks – especially the early movers – 2016 has become a year of reckoning, or biting the bullet and writing more checks for more coverage, perhaps seemingly too soon after the initial rollout.

Getting ready for Super Bowl LI

In Houston, NRG Stadium finally has Wi-Fi, and not a moment too soon, with Super Bowl LI on the near horizon. Since the venue didn’t have Wi-Fi prior to this season it’s not really an upgrade but it’s hard to understate the challenge of putting in a Super Bowl-ready network in just one summer, a construction calendar shortened by the fact that integrator 5 Bars and equipment vendor Extreme Networks had to wait until after the NCAA Men’s Final Four was over to begin installing cabling and APs. At of the start of the NFL season the Wi-Fi network is already live at NRG Stadium, and is sure to go through weekly tweaks as the league marches on toward its championship game.

And while attention-grabbing new stadiums like US Bank Stadium in Minneapolis and Mercedes-Benz Stadium in Atlanta are planning big network capacity from the get-go, some new stadiums like T-Mobile Arena in Las Vegas have upgrade thinking planned in from the start, with the idea that the network will never really be a finished product, at least until they stop making new phones or developing new apps. Of course, that future isn’t happening anytime soon, with the Apple iPhone 7 announcement with the new double-lens camera coming in just before the start of another football season.

New phones and new apps mean more bandwidth demands, leading even those who already have stadium networks to keep wondering if what they’ve installed is enough. We suspect this may be an ongoing story line for the foreseeable future, so – stay tuned here to Mobile Sports Report for the latest success stories and lessons learned from those who have already jumped in or jumped back in to the deployment fray.

Once just a series of drawings on a blueprint, Atlanta’s new Mercedes-Benz Stadium is getting more real by the day, with walls being added to steel beams, and wires for the internal networks being pulled into place.

Though the June 2017 opening day still is many months away, thanks to thoughtful planning many elements of the stadium’s network have already been tested, thanks to a facility created by stadium network officials to test components under situations as close to “live” as they could possibly get. That lab environment helped the network team make its final decisions on vendors and deployment methods, like going under-seat for deployment of most of the 1,000 Wi-Fi APs that will be in the stadium’s bowl area, part of a planned total of 1,800 APs in the entire venue.

In a recent interview with Jared Miller, chief technology officer at AMB Sports and Entertainment (the entity named for Arthur Blank, the owner of the Atlanta Falcons), Mobile Sports Report got an exclusive update on the construction progress so far for the new $1.5 billion facility, along with new details about the internal network deployment, which will be using more optical fiber than any previous stadium network we know of.

Like the network built at Texas A&M’s Kyle Field, the network inside Mercedes-Benz Stadium will have a single optical core for Wi-Fi, cellular and video, using the Corning ONE platform and deployed by lead network integrator IBM along with Corning.

Miller also confirmed our earlier report that YinzCam software would be used to host the stadium’s IPTV deployment, but vendor choices for Wi-Fi gear and a stadium app have yet to be named.

As construction teams continue to hustle toward completion of the building, here are more details from our conversation with Miller about how the Falcons’ tech team went through the process of determining the products and methods that would allow them to construct a network able to “push the limits” on fan connectivity.

Under-seat for Wi-Fi, with handrail heat sinks

In our early August conversation with Miller, he was happy to report that the planned 4,000 miles of optical fiber were finally starting to be threaded into the new building. “We’re making great progress with a ton of yellow cable,” Miller said.

While the overall architecture at the network core in Mercedes-Benz Stadium will be similar to the one IBM and Corning deployed at Kyle Field, Miller said that in Atlanta his team is pushing fiber even farther to the edge, “with only the last couple feet at most being copper.”

Miller said optical fiber, which can carry more data traffic at faster speeds than copper cable, is a necessary infrastructure underpinning for facilities like Mercedes-Benz Stadium that expect to host the biggest events like the Super Bowl and college football championship games. Mercedes-Benz Stadium is already slated to host Super Bowl LIII, the 2018 College Football Playoff Championship, and the 2020 Final Four.

“I really believe [fiber] gives us the foundation to grow and react in the future, to handle technologies we don’t even know about yet,” Miller said.

On the Wi-Fi side of things, Miller said that Mercedes-Benz Stadium will also mimic Kyle Field’s extensive use of under-seat APs in the bowl seating areas. Miller said the stadium will have 1,000 APs serving the seating areas and another 800 for the rest of the venue, for a total Wi-Fi AP count of 1,800.

Since the Mercedes-Benz Stadium network will be using more optical equipment closer to the edge, Miller said that his team used 3D printing experiments to craft custom enclosures for the under-seat APs, both to ensure they didn’t act as debris “traps” and also to add elements like an internal heat sink to diffuse the warmth from the extra electrical components. The heat sink solution involved attaching the AP elements to metal chair railings to dissipate heat, Miller said.

Testing the network before the building is built

After announcing its partnership with IBM in early 2015 as lead technology integrator, the stadium network team spent 6 months reworking the network design, Miller said, a process that confirmed the choice of optical networking at the core. Then to help the network team select gear and components, the Mercedes-Benz Stadium organization built a “full-scale lab facility” that Miller said allowed his team to build multiple live networks to test gear for performance and interaction with other network elements.

“The lab enabled us to see firsthand how gear behaved, not just alone but together [with other products],” said Miller, who added that at one time the network team had three simultaneous running stadium networks inside the lab.

“We were able to bring in different endpoint devices, like POS systems, and know how it’s going to behave [in a network],” Miller said. Plus, the network gave eventual business users of the planned gear time to get hands-on experience and training well before the stadium opens its doors.

On the DAS side of the network buildout, Miller said the stadium has an on-site, raised-floor room for DAS gear with “ample room” for future growth.

“One of those things we learned was that DAS [needs] always double,” Miller said.

YinzCam software for IPTV

Though the stadium hasn’t yet announced a provider for a game-day stadium application, Miller did confirm that Mercedes-Benz Stadium will use YinzCam software to control its IPTV system, which will cover the 2,500 or so TV screens inside the building.

“YinzCam is just the most intuitive and capable content management system,” Miller said.

Video is going to be a big part of the stadium from all angles, beginning with the one-of-a-kind “halo board,” a circular screen that will sit inside the retractable roof lines. For standard TV placements, Miller said Mercedes-Benz Stadium will use mainly 50-inch screens and will work with YinzCam to ensure the screens can be seen.

In the stadium’s suites, TV screens will be controlled by a tablet application; Miller said that Mercedes-Benz Stadium is also “contemplating adding the ability to control TV screens with a mobile app,” like the system YinzCam deployed at Texas A&M.

Friendly food pricing and more to come

Though Miller’s concerns are mostly technological in nature, he said there are still a lot of improvements coming to the stadium “that are not always reliant on brute technology,” like the new lower-priced food menus the Falcons announced earlier this year that seem to harken another era with $2 Cokes and $2 hot dogs. Miller said the stadium team continues to get feedback from a fans’ council, which has tagged the arrival and departure experience as one of the main pain points that needs fixing.

Mercedes-Benz Stadium will try to alleviate ingress and egress issues by doing things like creating “ticketed spaces” perhaps on the big outdoor plazas where many fans can congregate even before entering the stadium doors. By creating such spaces, Miller said fans might be able to enter the stadium more rapidly without the logjams that sometimes occur.

“We’re going to study arrival patterns and see what it looks like,” Miller said. “We have one more season to test those kind of things.”

Another amenity that may emerge is the use of wireless charging stations at a number of locations, to combat a scenario that Miller said often happens at marquee events, mainly fans’ phones draining their batteries as they compete with other devices to connect to a wireless network.

“We are focusing on providing amazing connectivity and pushing the limits,” Miller said. “We are looking at all kinds of options to allow fans to stay connected and not be separated from their device.”

IBM formally launches sports consulting practice to bring tech to stadiums

IBM formally cemented its entrance to the sports-stadium tech deployment market with the announcement of a sports and fan experience consulting practice, and a “global consortium” of tech and service suppliers who may help IBM in its future stadium and entertainment venue deployments.

For industry watchers, the Nov. 19 debut of the IBM “Sports, Entertainment and Fan Experience” consulting practice was not a surprise, since its leader, Jim Rushton, had already appeared at tech conferences this past summer, talking about IBM’s plans to deploy a fiber-based Wi-Fi and DAS network at the new Mercedes-Benz Stadium being built for the Atlanta Falcons. IBM was also publicly behind a similar network build over the last two years at Texas A&M’s Kyle Field. For both networks, IBM is using Corning optical gear.

Still, the formal creation of the IBM practice (you can read all about it at the new IBM sports website) means that the 800-pound gorilla is now firmly inside the competitive ring of the stadium-tech marketplace, a landscape that currently has multiple players, many of which have multiple stadium deployments under their belts. However, IBM’s vast experience in big-time sports technology deployments — Big Blue is behind such endeavors as the truly wonderful online experience of The Masters, as well as technical underpinnings of three of tennis’ Grand Slam events (Wimbledon, the U.S. Open and the Australian Open) — as well as its considerable tech and monetary resources probably makes it a No. 1 contender for all of the biggest projects as well as possibly smaller ones as well.

Rushton, who spoke with Mobile Sports Report earlier this year in one of his first public appearances as an IBMer, said in a phone interview this week that IBM’s fiber-to-the-fan network model isn’t just for large-scale deployments like the one at 105,000-seat Kyle Field or the Falcons’ new $1.4 billion nest, which will seat 71,000 for football and up to 83,000 for other events after it opens in 2017.

“That type of system [the optical network] is scalable,” Rushton said, and even in smaller venues he said it could potentially save customers 30 percent or more compared to the cost of a traditional copper-based cabled network. The flip side to that equation is that purchasers have fewer gear suppliers to choose from on the fiber-based side of things, and according to several industry sources it’s still sometimes a problem to find enough technical staffers with optical-equipment expertise.

How much of the market is left?

The other question facing IBM’s new consulting practice is the size of the market left for stadium tech deployments, an answer we try to parse each year in our State of the Stadium survey. While this year’s survey and our subsequent quarterly reports found a high number of U.S. professional stadiums with Wi-Fi and DAS networks already deployed, there are still large numbers of college venues as well as international stadiums and other large public venues like concert halls, race tracks and other areas that are still without basic connectivity.

With its new “global consortium” of companies that supply different parts and services of the connected-stadium experience, IBM could be an attractive choice to a customer that doesn’t have its own technical expertise, providing a soup-to-nuts package that could conceivably handle tasks like in-stadium IPTV, DAS and Wi-Fi, construction and stadium design, and backbone bandwidth solutions.

However, IBM will be going up against vendors who have led deployments on their own, and league-led “consortium” type arrangements like MLBAM’s project that brought Wi-Fi to almost all the Major League Baseball stadiums, and the NFL’s list of preferred suppliers like Extreme Networks for Wi-Fi and YinzCam for apps. Also in the mix are third-party integrators like CDW, Mobilitie, 5 Bars, Boingo Wireless and others who are already active in the stadium-technology deployment space. And don’t forget HP, which bought Wi-Fi gear supplier Aruba Networks earlier this year.

Certainly, we expect to hear more from IBM soon, and perhaps right now it’s best to close by repeating what we heard from Jared Miller, chief technology officer for Falcons owner Arthur Blank’s namesake AMB Sports and Entertainment (AMBSE) group, when we asked earlier this year why the Falcons picked IBM to build the technology in the new Atlanta stadium:

“IBM is unique with its span of technology footprint,” Miller said. He also cited IBM’s ability to not just deploy technology but to also help determine what the technology could be used for, with analytics and application design.

“They’ve looked at the [stadium] opportunity in a different manner, thinking about what we could do with the network once it’s built,” Miller said.

From the IBM press release, here is the IBM list of companies in its new “global consortium,” which IBM said is not binding, meaning that none of the companies listed is guaranteed any business yet, and others not on the list may end up in IBM deployments, like Kyle Field, which uses Aruba gear for the Wi-Fi:

Founding members of the consortium, include:

· Construction and Design: AECOM, HOK, Whiting Turner

· Infrastructure Technology/Carriers: Alcatel/Lucent, Anixter, Commscope, Corning, Juniper Networks, Ruckus Wireless, Schneider Electric, Smarter Risk, Tellabs, Ucopia, Zebra Technologies, YinzCam (IPTV), Zayo, Zhone

· Communications Solutions Providers: Level 3, Verizon Enterprise Solutions, AT&T

· Fan Experience Consulting & Data Management Integration: IBM

UPDATE: IBM: Sorry! No IPTV deal yet for new Atlanta NFL stadium

Artist's overhead view of new Atlanta NFL stadium

Update, 7/9/15, 5 p.m. PT: Sports app developer YinzCam has apparently not yet won the deal to provide IPTV technology for the new NFL stadium being built for the Atlanta Falcons, two days after an IBM exec said that they had.

According to Jim Rushton, global leader and partner in IBM’s sports and entertainment practice, he made some “factually incorrect” statements during a panel presentation Tuesday at the Association of Luxury Suite Directors (ALSD) conference in San Francisco. During his talk Rushton provided some high-level details of IBM’s plans to provide wireless networks and other technologies inside the 71,000-seat, $1.4 billion stadium that is scheduled to open in 2017, and both in his talk and presentation said that app developer YinzCam would be the IPTV technology provider for the new stadium.

However, in a subsequent phone call Thursday evening, Rushton said his statements about YinzCam were “factually incorrect,” and that in fact no contract has yet been awarded for the IPTV technology to be used at the Atlanta stadium. Hence this update to a previous version of the story which led with the YinzCam news, which was mainly new to us since Rushton didn’t name any other potential subcontractors, including the vendors who will be supplying gear for the passive optical network (PON) at the heart of the network or the provider of the Wi-Fi and/or DAS gear that will provide the stadium’s planned wireless connectivity.

However, we will stick with our original speculation, which pegs the leading candidates for optical gear and Wi-Fi equipment as likely Corning and Aruba Networks, who respectively supplied those same technologies for the IBM-led network deployment at Texas A&M University’s Kyle Field, where YinzCam also provided IPTV technology as well as technology for the stadium app. (Daktronics has already been announced as the supplier of the new planned Halo Screen video board.) So if YinzCam hasn’t actually inked a deal for IPTV in Atlanta yet, we will still keep them at the “most likely to win the contract” status.

During his talk Rushton said that network technologies still hadn’t been picked for Atlanta, with “proof of concept” testing still taking place in labs on site at the already-active construction zone. He also would not say whether YinzCam would also be part of the Atlanta Stadium app. YinzCam CEO Priya Narasimhan did not respond to email inquiries about the Atlanta deal (and maybe now we know why). On the Wi-Fi side it will be interesting to see if IBM still chooses to work with Aruba now that Aruba is part of HP after a $3 billion acquisition earlier this year.

Like at Texas A&M, IBM came late to the Atlanta stadium development process, but is claiming that its plan to build an internal fiber backbone for both Wi-Fi and DAS deployments has already saved space, time and money. Rushton said that in Atlanta the DAS headend will be located off the stadium site, a switch that opened up 10,000 square feet of stadium space.

New Atlanta football stadium picks IBM as lead technology integrator

The yet-to-be named new football stadium under construction in Atlanta has selected IBM as its lead technology integrator, somewhat officially welcoming the new 800-pound gorilla to the stadium technology marketplace.

While computing giant IBM has dabbled in sports deployments before — mainly contributing technology as part of its corporate sponsorship of events like The Masters in golf and the U.S. Open for tennis — only recently has Big Blue gotten into the large-venue technology integration game. And while IBM’s recent deal as technology integrator for the revamp of Texas A&M’s Kyle Field was probably its true debut, for the new Atlanta stadium IBM will lead the selection, design and deployment of a wide range of technologies, including but not limited to the core Wi-Fi and DAS networks that will provide in-venue wireless connectivity.

Due to open in March of 2017, the new $1.4 billion stadium is expected to hold 71,000 fans for football, and up to 83,000 fans for other events like basketball or concerts. And while soccer and concerts and basketball will certainly be part of its events schedule, the NFL Atlanta Falcons and owner Arthur Blank are driving the bus on the new building, picking IBM in part to help satisfy a desire to build a venue that will be second to none when it comes to fan experience.

In addition to Wi-Fi and DAS network buildouts, IBM will design systems to control the expected 2,000-plus digital displays in the planned stadium and will also oversee other technology-related parts of the stadium, including video security, physical door controls and a video intercom system, according to an announcement made today. IBM will also partner with the stadium owners to develop as yet-undetermined applications to “leverage the power of mobility to create a highly contextual, more personalized game day experience for fans, all through the integration of analytics, mobile, social, security and cloud technologies.”

In a phone interview Thursday, Jared Miller, chief technology officer for Blank’s namesake AMB Sports and Entertainment (AMBSE) group, said IBM’s depth and breadth in technology, applications and design made it a somewhat easy choice as lead technology partner.

Miller said the stadium developers looked at the number of different technology systems that would exist within the building, and ideally wanted to identify a single partner to help build and control them all, instead of multiple providers who might just have a single “silo” of expertise.

“IBM is unique with its span of technology footprint,” Miller said. He also cited IBM’s ability to not just deploy technology but to also help determine what the technology could be used for, with analytics and application design.

“They’ve looked at the [stadium] opportunity in a different manner, thinking about what we could do with the network once it’s built,” Miller said.

IBM, which also has a sizable consulting business, created a group targeting “interactive experiences” about two years ago, according to Shannon Miller, the North America Fan Experience Lead for the IBM Interactive Experience group. Miller (no relation to Jared Miller), also interviewed by phone Thursday, said IBM had been working with Arthur Blank and the Falcons for more than a year to determine how to make the new stadium “the best fan experience in the world.”

And while IBM is somewhat of a newcomer to the stadium-technology integration game, IBM’s Miller said the company not only understands “how to make digital and physical work together,” but also has resources in areas including innovation, technology development and design that smaller firms may not have. And while the Kyle Field project was ambitious, IBM’s Miller said the Atlanta operation will be much bigger.

“The size and scale of what we’re going to do [in Atlanta] will be unique,” he said.

No suppliers picked yet for Wi-Fi or DAS

For industry watchers, IBM and the Falcons team have not yet picked technology suppliers for discrete parts of the coming wireless network, such as Wi-Fi access points and DAS gear. (Daktronics has already been announced as the supplier of the new planned Halo Screen video board.) But those vendor decisions will likely be coming soon, since the stadium is under a hard deadline to open for the first game of the Major League Soccer season in March of 2017.

“We’re working fast and furious on design, and we want to identify [the gear suppliers] as early as possible,” said AMBSE’s Miller.

IBM and AMBSE did announce that the stadium’s network will be fiber-based, and will probably use Corning as a fiber and Passive Optical Network (PON) technology provider, though that choice was not announced or confirmed. IBM and Corning partnered to install a fiber network core for Wi-Fi and DAS at Texas A&M’s Kyle Field, believed to be the first large fiber network in a large stadium anywhere.

The Atlanta deal puts IBM solidly into the rapidly expanding field of stadium technology integration, which includes companies like CDW (which led network deployments at the University of Nebraska and the University of Phoenix Stadium) as well as stadium ownership groups, like the San Francisco 49ers, and technology name sponsors like AT&T, which has partnered with owners for technology and network deployments at venues like AT&T Park and AT&T Stadium.
