Dodgers up the ante with new Wi-Fi 6 network

Professional sports may have put games and exhibitions on hold, but a handful of IT executives from Major League Baseball teams have been using pandemic downtime to upgrade Wi-Fi and DAS systems in their stadiums.

Case in point: The Los Angeles Dodgers just completed the league’s first Wi-Fi 6 overhaul along with adding new 5G cellular antennas to ensure Blue Believers stay seamlessly connected to social media, email, text and good old-fashioned voice calls during home games. When baseball returns to venues, Dodger Stadium and the new Globe Life Field in Arlington, Texas, will lead the way as the first stadiums with Wi-Fi 6 fan-facing networks.

“We’re up against the same challenges that every stadium has, which is how to deal with the density of individuals trying to connect simultaneously – a challenge that’s unique to our industry,” explained Ralph Esquibel, vice president of IT for the Dodgers. “Wi-Fi 6 was created for this kind of high-density environment.”

Wi-Fi 6, better known in IEEE circles as the 802.11ax standard, is a significant upgrade for Wi-Fi networks that started appearing last year. Among its benefits are that use of the new standard can increase the amount of available spectrum and number of channels available for users; it can also significantly accelerate users’ average data rates, while also decreasing the amount of battery power used by devices searching for a Wi-Fi connection.

As long as they have newer phones that support the new standard, Wi-Fi 6 networks provide everything a team could want for its connection-conscious fans.

Replacing the Wi-Fi 4 network

Like its predecessor, the Wi-Fi 6 network will use under-seat APs in the bowl

It’s been barely five years since the Dodgers installed Wi-Fi 4 in the stadium, making use of under-seat APs and what were the league’s first APs cleverly concealed inside hand railings for even denser coverage. There were about 900 APs powering the network then, which easily accommodated 8,000 simultaneous users on its maiden voyage.

“It was state of the art back at that point in time,” Esquibel recalled. But usage and uptake quickly soared among fans and it wasn’t long before 30,000 simultaneous users were contending for bandwidth at each game.

“That was when I’d get a call from previous ownership, usually sometime in the second inning with, ‘I can’t get on email or make a phone call…’,” Esquibel laughed. Suddenly, it didn’t matter how close your seat was to home plate; anybody watching the game became inadvertent victims of Wi-Fi’s highly successful rollout at Dodger Stadium.

Other baseball stadiums experienced similar capacity and uptake issues. That’s in part what prompted MLB to dispatch its technology committee to look at technology upgrades to make sure baseball fans could do all the wireless networking they wanted to while watching a game. Though MLB did not respond to a request for more information, STR was able to get some information from other sources about the pending upgrade plans.

Wi-Fi 6 coming to more ballparks

According to our sources, MLB technologists settled on Wi-Fi 6 upgrades as their next strategic push. So while the Dodgers will be the first baseball team to upgrade to Wi-Fi 6, other teams were also reportedly in the first steps of adding Wi-Fi 6 before the coronavirus pandemic put a hold on many upgrade plans.

More APs were added in overhangs and roofed areas

It’s unclear if the MLB technology committee brought any financial help to the table along with their wireless expertise for these six upgrades. When MLB put together a consortium to bring wireless connectivity to parks starting back in 2014, it got financial buy-in from wireless carriers, equipment vendors and teams to help spread the costs around. Esquibel wouldn’t specify any dollar amounts for the Dodgers’ Wi-Fi 6 budget or whether the league contributed anything. He did note that the team negotiated an upgrade clause into its previous Wi-Fi networking contract.

Construction for the Dodgers’ new network began last fall, right after the Dodgers lost to the Washington Nationals in the NLDS playoffs. Back then, there were 880 APs that comprised the Wi-Fi 4 network; the upgrade to Wi-Fi 6 bumped that total closer to 1,100 APs, Esquibel said. The Dodgers installed 9100 series APs from Cisco in most of the same locations, reusing the cabling and conduits in the process. The Dodgers also replaced network switches (Cisco again, and its 9300 switching line) to handle greater throughput and the increased processing capacity, Esquibel added.

On the cellular side, Esquibel said carriers are adding 5G gear to the stadium, with AT&T having the most extensive deployment right now. Customers of AT&T and Verizon will also be able to be switched over to the Wi-Fi network when entering the park.

The upgrades to its wireless infrastructure also set the stage for some new capabilities coming down the pike. The combo of Wi-Fi 6 and 5G services will help the Dodgers deliver 4k and 8k video formats; it will also help as professional sports move toward “probability gaming,” i.e., online sports betting. Esquibel credits partners Cisco, AmpThink, Horizon Communications and MLB with building a powerful solution to enable these emerging services and capabilities.

Bench seating also got under-seat APs

There were other elements to the Dodgers’ 2020 tech stack refresh as well. Inside the stadium, they reworked the outfield to create a centerfield plaza with left- and right-field pavilions, with cut-outs and walkways above the pavilions plus more APs than last year to accommodate more seated and standing spectators. Esquibel said the team has also replaced its point-of-sale system, and has added Appetize, a cloud-based POS concessions app, as well as ParkHub to keep closer tabs on the Dodgers’ parking lots.

While the Wi-Fi 6 construction is complete, advance testing and fine-tuning are on indefinite hold. As of early June, Esquibel and his Dodger colleagues were sheltering in place and had been since mid-March.

“The pandemic has slowed down testing,” he said, nothing that the stadium needs capacity crowds to gauge how well the new networks are engineered and where antennas need adjusting. And it’s clear that contemplating the first post-pandemic home game brings out Esquibel’s fan boy, broadband wireless notwithstanding.

“I want to smell the grass and be with the crowd,” Esquibel said. “Like everyone else, I just want to see some baseball.”

Dickies Arena: Raising the fan experience to the highest level

Without a professional or major college sports team as a main tenant, it’s somewhat of a wonder that Dickies Arena in Fort Worth, Texas, got built at all. But once you step inside and attend an event there, the wonder shifts to the sheer excellence that surrounds you, in what may be simply the best-built arena-sized venue, anywhere.

It might seem like a Texas-sized stretch to make such a claim, but any other basketball-sized stadium similar to 14,000-seat Dickies Arena would be hard pressed to top the amenities, infrastructure and operations installed inside the new gem of Fort Worth. While first and foremost the venue serves as home of the annual Fort Worth Stock Show & Rodeo, a three-week-plus extravaganza that held its maiden run there earlier this year, when it’s safe to allow events to return Dickies Arena will also host concerts, ice shows and other sporting and non-sporting events, saving local folks from having to drive east to Dallas for a big-time experience.

But it’s opulence, comfort and service that will be the hallmarks of a Dickies Arena experience going forward, with those attributes far outweighing the convenience of just having a world-class venue in Fort Worth. During a visit by Mobile Sports Report during the middle of this year’s rodeo program (which ran 23 straight days from Jan. 17 to Feb. 8) we saw not just the visible attributes of perhaps the most polished finish of any arena ever, but also the underpinnings of important infrastructure assets like the wireless networks and video operations, and the intense level of attention to detail in food and beverage operations, all aimed at raising the fan experience to the highest level.

When we last visited the under-construction Dickies Arena in the fall of 2019, the finishing touches weren’t in place yet, even though we could see hints of what it was shaping up to be. For our late-January visit for a night of rodeo, we got to see the finished product in all its glory, and all we can say is, it may be some time before another venue even approaches the level of cosmetic finish achieved at Dickies Arena.

To be sure, not many venue ownerships may have the financial resources or the certainty of what they want out of a finished product as the team behind the creation of Fort Worth’s newest centerpiece. If you’re not familiar with the Dickies Arena story, the arena is part of a public-private venture between the city of Fort Worth and a consortium of investors and donors led by local Fort Worth philanthropist Ed Bass. As the home of Fort Worth’s namesake rodeo, Dickies Arena is clearly meant to be that and so much more, cementing in place a building where people who know what they want got exactly what they wanted – and more.

While we didn’t get to speak with Bass directly, his presence is felt in all areas of operation of the facility, with multiple stories of his direct involvement in making sure the smallest of details were adhered to. Even a first-time visitor to the rodeo could see and feel the devotion of leaders like Bass to their signature hometown event, from his riding a horse at the front of the event-opening parade to his video-board cameos of slapping bundles of cash into the hands of the event winners as the night progressed.

Behind the scenes, we heard stories about how Bass and the leadership team wanted very specific things done cosmetically – like making sure that no antennas for either the Wi-Fi or DAS networks were visible in any of the main public areas. To meet that challenge, main technical integrator AmpThink had to go outside the norm to design (and in some cases, custom-build) enclosures to hide the gear. Walking through the main concourses and seating areas, the only hint that wireless equipment might be overhead was the outline of flush-mounted panels, a design theme that even carried out to outside-wall mounting areas in the plaza areas around the arena’s exteriors.

Once inside Dickies Arena, visitors may feel like they are in somewhere more like an opera house than a multi-purpose venue (which on this night had a “playing floor” of some finely raked dirt). Floors of decorative tiles are underfoot, and railings on the staircases enclose sculptures of a distinctive local grass plant. That same design is reflected on the plates used in one of the premium seating areas, where the dining choices include a sit-down, white-tablecloth experience that looks like a four-star steakhouse inserted into the concourse.

Bill Shaw, the assistant general manager for Dickies Arena, was courteous enough to give us a directed tour of the venue before the night’s activities, pointing out things we might have noticed but not really realized, like the different tones and types of wood used for paneling, which changed as you moved from a higher premium seating area to a more general admission space. In the suites, Shaw showed us some especially comfy leather stadium chairs, which he said were the end result of a long process of determination to find out the best way to pad and tan the chair’s components.

Even the construction of the wheeled chairs in the loge box where we were the guest of AmpThink for the night were subject to scrutiny by Mr. Bass, we were told, with a story about him using tape measures to ensure the seat width was correct, and discussions about having the proper types of armrests that wouldn’t inadvertently snag the handles of a handbag.

“Mr. Bass spent a lot of time on all of that,” said Shaw. “His fingerprints are everywhere.”

To be sure, the somewhat unique ownership structure and the recurring revenue from the rodeo – which has sold-out status for all the premium seating spaces thanks to the families who have been supporting the event for generations – means in part that Dickies Arena doesn’t have to saturate its public spaces with advertising. While its digital display arsenal includes striking elements like curved LED screens from LG and menu boards and other displays running the Cisco Vision dynamic signage system, Dickies Arena only has a small number of partner-sponsors whose messages run somewhat discreetly compared to other arenas that may have more need to have a higher number of displays and advertisements.

The layout of the arena in general also takes its cue from how the premium seating space is used for the rodeo. Instead of a normal sort of top-down arena seating with “courtside” seats being the most desired, the wide space needed for rodeo events and the family atmosphere (most premium packages, according to Shaw, are bought by families and not corporations) means that there are “boxes” of seats ringing the lower bowl, with a wide walkway behind them to facilitate the meeting and greeting (and the seeing and being-seen) that is part of the rodeo culture. Thanks to some very clever architecture and movable stands technology, the mid-bowl walkway can disappear for events like concerts and other sporting situations like basketball; but good luck trying to figure out how that works by walking by the stands, since all the moving parts are, of course, hidden from view.

While a ring of suites provides another premium seating option a bit higher up, at either end of the venue are two more unique gathering areas, with belly-up bars that stretch almost the full width of the space, providing a place for the premium box-seat patrons to mingle while still having a clear view of whatever action is taking place. Shaw noted that at one end of the arena the seating can collapse back to almost a straight line, providing ample space for concert stages that also gives Dickies Arena a concert-seating total that Shaw said is comparable to American Airlines Center in Dallas, which seats 20,000 for NBA and NHL games.

Then there are some more touches you can’t see, like the bass-sound traps installed in the roof area to improve acoustics – and those you can see, like the soaring rooftop that is meant to mimic the open sky of Texas. As more fans attend different events scheduled in the future they are no doubt going to be impressed and perhaps surprised by the “opera house” where boots and Stetsons are the local fashion of choice.

Well wired for wireless

In our early fall visit to Dickies Arena we detailed the single, converged fiber network that supports all network operations, including the cellular DAS, the arena Wi-Fi and the IPTV operations, in an orderly, future-proofed way.

Built by AmpThink for the arena, the network is a departure from what has long been the norm in venue IT deployments, where multiple service providers typically build their own networks, with multiple cabling systems competing for conduit space. At Dickies Arena, AmpThink was able to control the fiber systems to follow a single, specific path, allowing the company to save costs and space for the client while building out a system with enough extra capacity to handle future needs for bandwidth, according to AmpThink.

According to AmpThink president Bill Anderson, one of those future needs became necessary this past fall, when Verizon wanted to bring its 5G millimeter-wave services as a late addition to the arena. To support the four 5G antennas that are now mounted up in the catwalk, Anderson said AmpThink was able to just allocate some of the spare optical fiber it has in place throughout the building, making it possible to bring in the service “in a very affordable way.”

In addition to the numerous custom enclosures used throughout the venue, Anderson said AmpThink also designed a pre-fabricated combination Wi-Fi and DAS antenna unit design that it could then hoist up into the rafters in a single pull. By having the green light to lead and innovate, AmpThink was able to develop and learn things it will draw on well into the future, Anderson said. “This is really our master class [on stadium network design],” Anderson said.

Since we spent most of our January time at the venue touring the spaces and talking to different representatives, we didn’t have that much time for network speed tests but the ones we did get showed the typical strong performances of an AmpThink-built network. On one of the concourses behind the suite levels we got a Wi-Fi speedtest of 67.0 Mbps on the download side and 65.0 Mbps on the upload.

Up at the highest level of seating, which is served from the rafter-mounted APs, we got a speedtest of 28.3 Mbps / 39.5 Mbps, during the night’s final event.

Though we didn’t get down there for a speedtest, the lower-bowl seats are served by under-seat Wi-Fi enclosures. According to Anderson there are approximately 550 Cisco Wi-Fi APs used throughout the venue, all of which are now the latest versions supporting the new Wi-Fi 6 standard. The DAS, which is overseen by ExteNet Systems, uses the Corning ONE DAS hardware system with approximately 258 active antennas in 11 zones for the DAS.

Keeping video and food and beverage operations in-house

Having never been to a live rodeo event before, Mobile Sports Report was somewhat in awe of the video production inside the arena, with multiple camera angles repeatedly in use on the large-screen centerhung videoboard. With no pauses, halftimes or timeouts, action was constant, and reflected as such on the main video screens.

We are simply going to have to revisit the arena for a more in-depth exploration of the video production operation itself, which is run entirely by the Dickies Arena team and even provides live feeds itself to cable channels covering rodeo. One of the more innovative twists inside the building is a concourse-level fan booth, where a large interactive video board can serve up multiple instant replays of rodeo action by clicking and dragging screenshots to the main display area.

The three-plus weeks of back to back rodeo action was somewhat of a stress test for the video crew, since almost every night there were different types of competitions (for instance, the night we attended there was a team competition, with scores from multiple events tabulated into a final team score) requiring custom programs to populate the video board displays. According to the video team there were no fewer than seven different scoring programs in play each night, but they were able to coordinate the results so quickly that they actually had to introduce a time delay into the reporting from judges to the video screens, so that the announcers could add some drama to their live play-by-play.

On the food and beverage side of operations, the do-it-ourselves theory of Dickies Arena meant that the arena controls all aspects of F&B operations, instead of contracting much of the work to a third-party caterer.

Julie Margolin, director of food and beverage operations at Dickies Arena, said it starts with little things, like not having to live with a certain brand of hot dog because that is the brand a caterer carries. But then it expands into what is possible, and why you would try to do things like provide in-seat delivery service to 4,000 premium seats while also balancing the F&B needs for a diverse operation that includes white-tablecloth dining, suite operations, high-end bar areas, and mobile point-of-sale to support cotton-candy sales on the concourses.

“We do everything we can to make sure every experience is the best,” said Margolin. “That’s a task not a lot of people are willing to take on.”

But Margolin, who previously held a similar title at the Honda Center in Los Angeles, is like other top performers who found the opportunity and challenge presented by Dickies Arena too good to pass up.

“This building is very different than others in the industry,” said Margolin, citing the close working atmosphere that rapidly built between operations and construction and information technology teams as the building opened late in 2019 ahead of the real debut, the rodeo season.

“If something needed fixing, nobody went home until it was done,” Margolin said. And while like others she’s always looking for ways to improve, Margolin said the whole idea of a venue owning and operating its own F&B was an exciting challenge.

“If you go with someone else’s [catering] model, you’re serving two masters,” Margolin said. But trying to meld numerous different types of fan experience operations, she said, is a challenge worth pursuing.

“If you stick with the status quo, you’re going backwards,” she said.

Dickies Arena: As good as it gets?

Standing outside the arena on a clear-sky night, from one of the outdoor plazas, fans have a pleasing view back toward the lighted buildings of downtown Fort Worth. Legend has it that Ed Bass purchased the land Dickies Arena sits on more than three decades ago, with the vision that someday he would help build an arena with that signature view back toward downtown. Now that that dream is reality, the sky’s the limit for what Dickies Arena future may be.

Though the coronavirus has effectively put all arena schedules somewhat on hold, prior to the outbreak Dickies Arena had already announced future bookings for big-name concert acts as well as family events like Disney on Ice, Cirque du Soleil and even the U.S. Gymnastics Championships. Clearly, the events market will make use of a venue of Dickies Arena’s size and stature.

According to Shaw, patrons with rodeo season tickets get first dibs on other events, but it’s a good bet that the diversity of action inside the Dickies Arena walls will mean that a wide number of fans will be able to experience the wide range of seating options available. But even those attending on the least-expensive tickets will still be able to experience the overall quality of all aspects of the arena, which will be hard for other venues to match.

‘Best of Breed’ wireless drives Chase Center experience

As stunning as Chase Center is visually, what you can’t see is equally powerful in adding to the fan experience. Namely, the wireless networks, and the gear that supports the connectivity.

Inside the shiny new home of the NBA’s Golden State Warriors, which sits on the edge of the San Francisco Bay, is a cellular DAS deployment from Verizon using Corning gear that may be the new forward-thinking model for cellular infrastructure for large public venues like stadiums and arenas. The 18,000-seat arena also has a Wi-Fi network using gear from Aruba, a Hewlett Packard Enterprise company, which supports the emerging Wi-Fi 6 standard for communications inside the main seating bowl.

But if you’re attending a Warriors game, or one of the many concerts scheduled at Chase Center, you may not ever see the equipment that brings the world-class connectivity to the fans. Both the DAS and the Wi-Fi networks utilize an under-seat antenna deployment method, just part of an aesthetic plan that does its best to minimize the visual impact of antennas and other wireless gear. Even deeper into the building is all the optical fiber supporting the networks, with capacity for future needs already in place.

During a mid-October 2019 visit before all the networks were fully tuned, Mobile Sports Report still got strong test results from both Wi-Fi and DAS networks in most areas in and around the arena, clear confirmation that the Warriors’ goal of having excellent wireless connectivity at their new home was right on track. And with the Corning ONE system in behind a DAS design built from the ground up with future needs in mind, as well as the expected capacity gains coming from Wi-Fi 6, the Warriors and their partners are confident they’ve built a wireless system worthy of their world-class venue goals.

“We feel extremely proud” of the venue’s wireless systems, said Brian Fulmer, director of information technology for the Golden State Warriors. Though the inevitable construction delays led to some late nights heading up to the arena’s Sept. 6, 2019 public debut, according to Fulmer all wireless systems were fully online for the opening Metallica concert, where the arena saw 2.58 terabytes of data used on the Wi-Fi network with another 2.69 TB used at another Metallica show a couple days later.

“It was a race to the finish line but we did it, and the performance speaks for itself,” said Fulmer.

Searching for ‘Best in Breed’

If there was ever a chance to build the best-ever new arena, Chase Center was probably a once-in-a-lifetime opportunity. When you combine the championship run of the team on the court with a devoted fan base centered in one of the hottest economic markets ever, you have the liberty to search for quality instead of bargains on every level.

A Wi-Fi AP hovers over a concourse gathering area.

(Case in point: The Warriors were able to sell out of their new court-level luxury suites, which have rooms just under the stands that include private wine lockers and can cost up to $2 million per year. Clearly, this is a model that may not work in places that aren’t Silicon Valley.)

For the privately financed $1.4 billion building, the Warriors turned to consulting firm Accenture to help determine the “best in breed” technology partners, especially on the wireless front. Several Warriors executives interviewed for this story did all agree on one main point: The team was not trying to install any technology to win imaginary awards for being the best or fastest building out there. Instead, it was all about how technology, especially wireless, could help bring about a world-class experience during every visit.

“Nobody shows up [at an arena] just looking for fast wireless speeds,” said Mike Kitts, the Warriors’ senior vice president for partnerships. “They want to interact. We wanted to create unforgettable experiences in an engaging environment. With the end in mind of a world-class experience, we knew great technology would absolutely play a role.”

Like a team drafting top players, the Warriors ended up choosing Verizon to lead the distributed antenna system (DAS) for cellular wireless, and Aruba for Wi-Fi. To build its neutral-host system, Verizon chose Corning and the Corning ONE platform, with an installation led by Communication Technology Services (CTS).

“We certainly leveraged the expertise of Verizon, as well as AT&T (which is also on the DAS as a client),” said Fulmer. “They’ve done this countless times, and they have the lessons learned of painful experiences.”

Building a DAS that can handle growth

Anyone in the stadium business in Northern California doesn’t have to look too far or remember too long ago to recall one such example of the pain that the nonstop growth in cellular demand can cause. After the San Francisco 49ers’ brand-new home, Levi’s Stadium, opened in 2014, the also brand-new DAS had to be upgraded the very next season to ensure it had enough capacity for the upcoming Super Bowl 50. Verizon, which basically invented under-seat DAS antennas for that deployment, said it had a goal at Chase Center to build a DAS that didn’t need upgrading for at least a few years.

A Wi-Fi AP painted to blend into the outside facade.

Terry Vance, senior manager for Verizon’s Pacific market network performance group, said “the plan from day 1 was to build a DAS with capacity for today and tomorrow. We needed to build this DAS so that for the next 3 to 4 years, we won’t have to touch it.”

Verizon also had to build the DAS in a way that complied with the Warriors’ stringent requirements for clear sight lines, especially in the main bowl seating area. According to the Warriors’ Fulmer, the team “looked at handrail [enclosure] designs,” but rejected them in favor of an under-seat approach. Though more costly in both equipment and construction, the under-seat approach was Verizon’s favored method as well to get more density in the arena.

What Verizon ended up with was a design that currently uses 71 active sectors, with 42 of those in the seating bowl. According to Vance, all the sectors in the bowl area can basically be split into two parts if needed, for a total of 84 potential bowl sectors. Currently, Vance said there are 598 under-seat DAS antennas in use.

According to Vance the Corning ONE system’s extensive use of optical fiber makes it easier to add capacity to the system as needed.

“The fiber to the edge [in the Corning system] is especially useful as you go to 5G,” Vance said. Though it’s not part of the shared DAS system, Verizon also has full 5G bowl coverage at Chase Center, one of the first arena deployments in California. Verizon also is using a couple of MatSing ball antennas, mounted in the rafters to provide cellular coverage to the floor area for concerts and other non-basketball events.

Right now AT&T is the only other carrier on the DAS, with participation from T-Mobile and/or Sprint pending depending upon the outcome of those two companies’ potential merger.

Jessica Koch, sports and entertainment director of business development for Corning optical communications, gave praise to integrator CTS for its deployment know-how, which she said was “critical to the success of this project.” Corning, Koch said, knows that for fans in large venues like Chase Center, “reliable connectivity without restriction – all the time, at full speed, on any device, from anywhere – has become the expectation in our connected world.”

For Warriors president and COO Rick Welts, the best wireless system is one fans don’t see or worry about, but just use without concern.

“The best thing is if the phone just works, and I don’t have to think about it,” said Welts, who led a stadium tour during MSR’s October visit.

Though Verizon said the system went through some necessary optimization during the hectic early events schedule at Chase Center, Verizon engineers in December were getting DAS speed tests in excess of 100 Mbps for both download links in most locations, according to Philip French, vice president of network engineering for Verizon. Download speeds for 5G connections, he said, are breaking the 1 Gbps mark.

“This DAS is unique since it was the first one we’ve built with 5G in mind from the ground up,” French said. “It’s a very robust design, and for us this is the design of the future.”

Leading the way with Wi-Fi 6

Like several other stadiums that were being finished this past summer, Chase Center was able to take advantage of the release of Wi-Fi equipment that supports the emerging Wi-Fi 6 standard. Though all the new capabilities won’t be fully realized until most end-user devices also support the new version of Wi-Fi, having support for the technology inside the arena was key for the Warriors’ plans.

“You can never really be ‘future proofed’ but we were extremely fortunate with the timing [of Wi-Fi 6 gear arriving],” said the Warriors’ Fulmer. “We were right in the sweet spot for an initial deployment.”

According to Aruba, Chase Center has approximately 250 Aruba 500 Series APs (which support Wi-Fi 6) deployed in the main seating bowl, mostly in under-seat enclosures. Overall, there are approximately 852 total APs used in the full Chase Center network, which includes coverage inside the building as well as in the connected outdoor plaza areas.

During our October visit, MSR got Wi-Fi speedtests of 27.3 Mbps on the download side and 18.2 Mbps on the upload side while standing outside the east entry doors near the big mirror balls that are selfie central for fans visiting the new arena. Inside the doors, our speedtest in the lobby got a mark of 55.8 Mbps / 68.6 Mbps.

On one upper concourse area, near several concession stands outside portal 57, we got a speedtest of 10.5 Mbps / 11.2 Mbps. In the seats in upper section 220 just before tipoff we got a mark of 46.0 Mbps / 28.0 Mbps, and in a lower-bowl concourse area outside portal 9 we got a test mark of 53.7 Mbps / 71.5 Mbps.

According to Aruba, several events other than the Metallica concerts have passed the 2 TB Wi-Fi data mark so far, with several events seeing more than 8,000 unique clients connected and marks of 6,000+ concurrent connected devices and 2.6 Gbps of throughput.

The Warriors’ Fulmer praised not just the Wi-Fi gear but the full “end to end network solutions” available from Aruba as well as from parent Hewlett Packard Enterprise, which is a founding partner at Chase Center.

“We’re still only three months in, and there’s a lot more that we want to do,” Fulmer said. “It was not a small undertaking. But I think we can let the technology speak for itself.”

Fiserv Forum’s wireless networks ready for the Democratic Convention

With one of the most demanding arena-sized events headed its way this upcoming summer, the wireless networks at Milwaukee’s Fiserv Forum appear to be more than ready to handle any audience demand for mobile connectivity.

With a full-featured distributed antenna system (DAS) deployed and operated by ExteNet Systems using gear from JMA Wireless, as well as a Wi-Fi network using Cisco gear, Fiserv Forum shows both the expertise of wireless providers who have a long history of knowing what works, as well as the foresight to add new techniques and technologies to combine high performance with the quality aesthetics that are the hallmark of the new home of the NBA’s Milwaukee Bucks.

And while a Mobile Sports Report visit this past fall for a Bucks game found all the wireless elements in top working order, the big event for the venue’s second year of operation will be the Democratic National Convention in July 2020. While the four-day nomination gathering is a test for any locale, Fiserv Forum’s forethought on how to prepare for numerous types of events in and around its uniquely designed structure has it well prepared to handle whatever wireless needs the convention will require.

It all starts with the DAS

Even in these days of predictions of the death of DAS, Fiserv Forum is proof that for high-profile venues, carriers will still participate in a quality deployment. And while many venues have just two or three cellular providers on their DAS, according to ExteNet, the Fiserv Forum DAS has five major carriers participating — AT&T, Verizon, T-Mobile, Sprint and U.S. Cellular.

Unlike some new arenas, where wireless is an afterthought to construction, ExteNet was involved early on, according to Manish Matta, vice president of marketing at Extenet.

“Getting in sooner rather than later is always better,” said Matta, who said ExteNet was well involved in the overall construction plans, ensuring that there were no delays associated with wireless deployments holding up construction of other parts of the building.

During a pregame tour in October with a team from ExteNet as well as with Robert Cordova, chief technology and strategy officer for the Bucks, Mobile Sports Report got an up-close look at some of the inside parts of the DAS network design, including the headend room and multiple antenna installations that were hard to find given their well-designed placements and camouflaging.

In addition to regular enclosures that were painted or otherwise placed in areas out of the main sight lines, ExteNet and JMA also utilized some of the newer circular flat-panel antenna enclosures that fit flush to ceilings, minimizing the exposure.

The 215 DAS antennas are powered by 40 remote units. According to JMA, the remotes are connected to the backbone with optical fiber, and use digital power to bring power to elements up to a mile away. With 16 sectors in the bowl design, the DAS is able to segment coverage to all parts of the arena, including the bowl as well as concourses and other in-house areas.

ExteNet, which owns and operates the DAS as a neutral host, also installed 10 extra MatSing ball antennas in the rafters for additional top-down coverage. Though only AT&T is using the MatSings right now, ExteNet said they are integrated into the DAS design if other carriers should wish to utilize them in the future.

During a short walk-around before the Bucks game started, MSR got a DAS speedtest of 85.8 Mbps on the download and 14.9 Mbps on the upload, even though our older iPhone (on the Verizon network) doesn’t support all the latest DAS capabilities. Near the start of the game, as the pregame introductions were at their peak, we got a DAS mark of 18.0 Mbps / 15.7 Mbps in the middle of an upper-deck seating area (Section 227) and then a little bit after the game started, we got a mark of 21.3 Mbps / 12.5 Mbps near a bar area on the upper-level concourse.

Wi-Fi inside and out

On the Wi-Fi side of things, a visitor to Fiserv Forum can connect to the network even before coming in the doors, as part of the 623-AP Cisco installation includes Wi-Fi APs mounted on light poles in the “Deer District,” the plaza area on the stadium’s east side that connects to an outdoor beer garden and several bars and restaurants that were all part of the planned environment built in sync with the arena’s opening.

Before we went inside, we got a Wi-Fi speedtest of 40.5 Mbps / 40.2 Mbps in the middle of the Deer District plaza, which was hosting a pop-up haunted house attraction sponsored by Jack Daniels.

Inside the building, we again needed some guidance from the Bucks’ Cordova to locate some of the Wi-Fi APs, which are inside triangular enclosures that are either painted to match wall surfaces, or utilized as high-visibility section number signs, hiding the gear in plain sight.

In the seating bowl, Fiserv Forum again shows its commitment to aesthetics with the smallest handrail enclosures we’ve ever seen, a discreet hand-sized enclosure that tucks the antenna components neatly into the top part of a railing, with the AP electronics hidden below the seating areas. Designed by integrator Johnson Controls and its ecosystem partners, Abaxent and AccelTex, the 28 special enclosures are also designed to be easy to detatch and re-attach (with something Johnson Controls calls a simple two-click “dart connector”) which facilitates keeping the network working when the lower-bowl seating areas need to be reconfigured for different events.

Sitting in a courtside seat near one of the handrail enclosures about 20 minutes before tipoff, we got a Wi-Fi speedtest mark of 15.8 Mbps / 33.2 Mbps. On the main concourse just after the game’s start we got a Wi-Fi mark of 28.6 Mbps / 60.4 Mbps, and later on at that same upper-concourse bar we got a mark of 39.9 Mbps / 61.1 Mbps.

Later on during the second quarter of the game, we watched another fan in our lower-bowl seating area spend most of the period keeping one eye on Monday Night Football streaming on his phone. “The Wi-Fi is really good here,” he noted.

Looking ahead to CBRS and 5G

As ExteNet and JMA prepare for the onslaught of the convention’s needs, in many areas the Bucks are already looking farther ahead, to future communications improvements including 5G millimeter wave deployments, and a possible introduction of CBRS services. Cordova, who is an advocate of the capabilities of private LTE networks over the CBRS spectrum, said the flexibility of provisioning services in a CBRS environment could be extremely useful for temporary needs, like during last year’s NBA playoffs when the NBA on TNT crew set up a temporary stage out in the plaza.

While the Bucks have already prepared for connectivity of all sorts out on the plaza space – from the top-level outside Panorama deck at Fiserv Forum that lets fans look out over the city, Cordova pointed out several metal boxes in the plaza that have home-run fiber connections for broadcast TV as well as remote power – there’s going to be all sorts of temporary connectivity needs when the convention media tents set up in the empty lot next door where the previous stadium, the Bradley Center, used to stand.

The fact that the Bucks and ExteNet were already well involved with planning for a July event in October the year before is just another sign of a networking operation that is well positioned now and already thinking about what the next necessary steps are.
