At the very least San Francisco 49ers fans Sunday could take heart in the fact that the wireless network in Levi’s Stadium largely lived up to its advance billing, performing quite well even as the team on the field sputtered and failed to connect. In its first “real” test with an almost-full house on Sunday the Levi’s Wi-Fi and cellular networks seemed to work well throughout the game, delivering solid speed test results from almost every part of the new 68,500-seat facility, even as Colin Kaepernick and the rest of the 49ers were dealt a 34-0 preseason drubbing by Peyton Manning and the visiting Denver Broncos.

And just like the team, the Niners’ stadium technology lineup still has some weak spots that will hopefully be fixed before the regular season home opener on Sept. 14. Among the disappointments Sunday was a no-show by the highly heralded instant replay feature, the crown jewel of the new Levi’s Stadium app. We also experienced some location-connection problems with one of our devices, exposing what we consider a flaw in the Levi’s app, namely an over-reliance on location technologies to enable key parts of the app, like wayfinding and on-site video streaming.

Some other not-so-advanced technology flaws that could use fine-tuning include the volume level on the main stadium public-address and announcing system, which was so loud that it made it a struggle just to talk to the person next to you for long stretches of time. The ticket scanning machines also seemed to have issues working in the bright sunlight, a problem that found a low-tech fix when ticket personnel placed Niners’ visors around the tops of the machines to shade the scanning area. And many concession stands around the stadium were unable to serve guests or could only take cash because the staff operating the stands said they weren’t given access codes to the point-of-sale systems.

Overall, however, the first football game at Levi’s was a success on many levels, including the fantastic sight lines available from most seats and largely incident-free travel and parking operations, with noticed improvements especially on the VTA light rail front that struggled mightily during the stadium’s opening-event soccer game two weekends ago. Most fans also probably got a little weight loss from the no extra-charge sauna situation, thanks to the cloudless day and bright sun that bathed most of the seats in searing heat for long times after the 1 p.m. start.

Smooth start for early VTA riders

What follows here is a somewhat minute-by-minute account of my trip to the game, and my experience with the network and stadium operations on site.

Since I wasn’t given press access to the game, Mobile Sports Report attended like a regular fan, purchasing a single ticket through the NFL Ticket Exchange service on the 49ers’ web site. My plan to get to Levi’s from San Mateo was to drive to downtown Mountain View, park there and take VTA the rest of the way. (I didn’t take CalTrain mainly because I didn’t want to have to sync my return schedule with the CalTrain options going northbound on Sunday.)

Though I was somewhat incredulous about having to buy tickets online — VTA said that the ticket machines in Mountain View would be shut down Sunday to keep big lines from forming — upon further review the VTA app was slick and easy to operate and understand. After purchasing a ticket for $6.50 Saturday night I activated it Sunday, and showed it at the gate where they checked boarding passes. For people who didn’t have tickets there was a tent set up where they could buy a pre-loaded Clipper card for $10 good for a day’s worth of VTA riding. There was an abundance of VTA workers on hand, as well as a large and very obvious police presence. As a nice touch there was also a large bank of porta-potties, and behind the trains there were express buses waiting, according to one VTA employee, in case of crowd overloads.

“We learned some lessons from two weeks ago,” he said.

If there was a glitch in the VTA operations it was with the city of Mountain View — though a couple city lots were designated as places where fans could buy all-day parking passes, and there were clear signs to those lots, at 9:30 a.m. those lots were not yet staffed with anyone to pay; MSR found one sign leaning up against a post, waiting to be deployed. Fans could also park in the CalTrain lot for $5, payable via the CalTrain track podium ticket machines.

I boarded the first VTA train to leave for the stadium, along with many fans who had just gotten off CalTrain. The pleasant, air-conditioned trip took just 27 minutes, passing many Silicon Valley company headquarters and one neighborhood with “no parking here” patrols before stopping pretty much right at the Levi’s Stadium entrance. A few steps later I was in the parking lot, and took the first of many Wi-Fi speed tests and got a signal of 29 Mbps download and 23 Mbps upload, a good sign for network operations.

Looking for Wi-Fi, finding lots of it

Once inside the gates — and past the shaded scanners — I started speed testing in earnest, with the two devices I brought with me: A Motorola Droid 4 on Verizon, and a Samsung Galaxy Note 3 on AT&T. While waiting for the main stadium gates to open at 11 a.m. I got the weakest Wi-Fi signals of the day along the “Faithful Mile” area where promotional booths from sponsors kept early arrivers entertained. Wi-Fi on both devices out there only hit 2 to 3 Mbps on the download, while cell signals on both devices were in the 6-7 Mbps download range. Since I could see multiple DAS radios in the area but not any Wi-Fi access points I wasn’t too surprised; but it was an unusual area not to be blanketed with Wi-Fi, especially since there was good access a couple hundred yards away in the parking lots.

After finally entering the stadium proper, I ran into Niners president Paraag Marathe — who said he was “nervously excited,” and looked ready to start sweating in his suit and tie. “We’ve just got to make sure everything works today,” Marathe said, shaking my hand. Then I went up the escalator and saw the “Kezar pub,” an open-air bar filling the top area above the Intel gate. There, draft beers like Shock Top and Goose Island IPA were available for $11, and bottled beers available for $10.25.

As I started walking around the outside concourse I took my first speed test in the stadium and it blew the needle off the edge: 57.92 Mbps download, 41.00 Mbps upload.

A few minutes later on the inside concourse (where most of the concession stands are) I hit 27.85 Mbps/21.34 Mbps, still impressive. Then I tried to launch the app, and — problem. Apparently the device wasn’t connecting because it wouldn’t show my location on the wayfinding app. Luckily, right in front of me was Racquel, one of the “NiNerds,” the team’s new staff of technical experts who are there to help fans make the app work. But Racquel couldn’t solve my problem, even after we both tried turning on all location services, including Bluetooth.

“I can try to find another NiNerd who might know more about this device,” offered Racquel, who was visibly dismayed at her failure to help solve my problem. Instead, I moved on, hoping that the problem would solve itself later. But it didn’t.

Failure to locate… and other app problems

After downloading the Levi’s app to both devices over the weekend, I noticed that the first item on the app list of functions — Tickets — required me to “sign in” with my “Stadium Ticket Account,” something I didn’t have and didn’t know how to get. I did figure out how to enter my purchased seat location (which I could have used to order food to my seat, or for the express pick-up option), but I could never get the location feature to work on the Samsung device, which kept me from being able to see the live streaming TV option (I kept getting a message that said, “You must be at the stadium to play this video”). I was able to watch the live TV option on the Motorola device, after turing on location services. But for both devices — and, as it turns out, for everyone in the stadium — the final feature on the app, Game Center, where we were supposed to be able to see all the instant replays we could handle, remained labeled “coming soon.”

Finally sitting in my most excellent seat — section 244, row 3, seat 17 — I noticed that the Motorola device could no longer connect to Wi-Fi, even as the Samsung device was hitting marks in the 15-16 Mbps range. I started tweeting about the problem, and instead of a NiNerd coming to help me I got a personal visit from the Levi’s version of a Jedi Master, namely Dan Williams, the team’s vice president of technology. (Never underestimate the power of a complaining tweet!)

On my own, I had guessed that the Droid’s inability to connect came from its having only a 2.4 GHz Wi-Fi radio. If you’re not familiar with Wi-Fi networks, the 2.4 GHz band of unlicensed airwaves is what most first-generation Wi-Fi networks used; more recent devices are able to also use the 5 GHz band of unlicensed airwaves, which simply offer more channels and more bandwidth. The iPhone 5s, for example, mainly uses 5 GHz for Wi-Fi, as does my Samsung Note.

In scanning the available Wi-Fi networks, I had also noticed something else that I thought could be gumming up the Droid’s connection — a bunch of personal Wi-Fi hotspots in the immediate area, including several labeled as GoPro cameras. After curiously examining my Droid 4 — and its slide-out keyboard — Williams and a technician from Wi-Fi gear provider Aruba Networks concurred that my device was getting bogged down in the 2.4 GHz mess, and also wasn’t refreshing the available networks list, a device-specific problem.

Bottom line? Levi’s is no country for old phones.

Initial verdict: Wi-Fi and cellular is world class… but app needs work

After staying into the third quarter — and visiting another friend in section 109, where I got another hefty Wi-Fi speed test (24.42/25.39 Mbps) — I followed the lead of many fans and took an early leave of Levi’s, which meant no lines at the VTA trains and just a couple short delays due to track congestion that stretched the return train trip to 40 minutes. Overall, my travel to and from the stadium from San Mateo took just over an hour each way, a happy stat to report.

My initial verdict is that the Wi-Fi and DAS (cellular) networks delivered as promised, with solid speeds all around the stadium every time I checked. It’s no small accomplishment just to deliver such world-class service to such a crowded space, especially in the middle of Silicon Valley. True to its roots, the crowd Sunday was device-happy, with many iPads and GoPros being carried around as video cameras, in addition to all the phones that were in constant use. It’s a tribute to Williams and his staff, as well as the technology suppliers like Aruba, Brocade, Comcast (backbone bandwidth supplier) and DAS Group Professionals, who built the distributed antenna system (DAS) which brings advanced cellular connectivity inside the gates, to have built a solid network that worked well on its first big test.

The team app, however, did not even come close to living up to its advanced billing. To equal the network I think the app needs more advance instructions, especially on the ticketing/registration options as well as on the location services needed to make everything work. And until we see the multiple-camera angle live replays in action, to me the app is an incomplete project. The good news is, the Niners and their technology teams have several weeks to make improvements, including another preseason game Aug. 24 against the San Diego Chargers.

It’d also be helpful for the team to reach out a bit more to the VTA and players like the City of Mountain View, since the VTA site maps and Mountain View’s parking maps are far from what you would call “advanced design.” I think it’s up to the Niners to help pay for improvements to the city and transportation entities’ technology offerings, simply because of the burden placed on those operators by the fans going to Niners’ games. At the very least, more links from football to getting-there operations seems in order, instead of trusting that all parts of the operation will work in sync.

Stadium Tech Report: AT&T brings Wi-Fi and IPTV to Wisconsin’s Camp Randall Stadium

Screen Shot 2014-08-12 at 12.36.29 PMThe University of Wisconsin’s Camp Randall Stadium, a facility built before those things called telephones were in widespread use, is finally getting the technology it needs to let current-day mobile devices stay connected: A high-speed Wi-Fi network and a stadium-wide IPTV system, which will both be deployed by AT&T before the first kickoff this fall.

While few people probably had any kind of working telephone when Camp Randall was built in Madison, Wisc., in 1917, things are a lot different now, as most people own at least one mobile device. Prior to this season, visitors to the 80,321-seat Camp Randall experienced the frustration familiar to many who visit crowded public spaces: the dreaded “no signal” notice, or calls or texts that went nowhere.

“If you worked in the stadium, on game days it was hard to get online, or even send a text,” said Justin Doherty, Wisconsin’s associate athletic director for external relations, in a recent phone interview. According to Doherty, recent fan surveys showed that improving wireless service was a top request. After issuing an RFP, Wisconsin chose AT&T as its partner in the reported $6.2 million networking project, which will also include the deployment of 700 high-definition TV screens throughout the stadium. On the Wi-Fi side, AT&T will provide a 10 Gigabit backbone connection and will install approximately 750 Wi-Fi access points throughout the facility.

Combining Wi-Fi with DAS

Though AT&T executives have stated publicly that DAS can sometimes take care of all the connectivity needs in a stadium, the phone provider giant also said that installing DAS and Wi-Fi together can create “the optimal user experience” by allowing both technologies to do what they are best at. In the stadium network world, that usually means allowing DAS to handle simpler communications like phone calls and texts, while allowing Wi-Fi to handle heavier bandwidth loads, like streaming video.

In a somewhat interesting twist, AT&T — which has deployed numerous DAS systems in stadiums — does not run the DAS at Camp Randall Stadium. According to Doherty, the Camp Randall DAS is run by Crown Castle, with AT&T and Verizon as customers. The AT&T Wi-Fi installation, however, will significantly increase the amount of available wireless bandwidth, taking a lot of congestion away from the cellular network as a critical first task.

Beyond providing pure bandwidth, Wisconsin doesn’t yet have solid plans on how it expects to use the Wi-Fi network. Doherty said that innovative ideas like instant replay and food-ordering apps being installed at some other venues are things Wisconsin will be looking to deploy in the near future.

“There’s a lot on the plate, but we want to walk before we run,” Doherty said. “We’re going to be in a little bit of a learning mode [early on], trying to understand how to run the network. By the seventh game [this season] we should be a lot better.” According to Wisconsin and AT&T, the network is expected to be ready by the time of the first home game this season, Sept. 6 vs. Western Illinois.

Though it wasn’t spelled out in the press release, Doherty said that AT&T will be using Cisco Wi-Fi hardware, along with Cisco’s StadiumVision system to provide the video feeds to the in-house digital displays. One of the features of the StadiumVision system that is of great interest to Doherty is the ability for administrators to split the screen in different ways, such as including an L-shaped advertising border around the edges. Though in the future that might be used to sell advertising, Doherty said Wisconsin will most likely use the displays to promote other sports.

“You might see a game feed on the main part of the screen, and then in the L-wrap area we might promote ticket sales for hockey games,” Doherty said. “We also might use it for social media feeds. We’re going to be heavy on internal messaging this fall.”

According to Doherty, the Wisconsin IT team scouted some other school and pro facilities to get ideas of how to best implement wireless deployments. Among the venues visited were the Rodgers Centre, home of the Toronto Blue Jays, and Sports Authority Field at Mile High in Denver, home of the Denver Broncos.

“All those people we visited were very helpful,” Doherty said. “You have to pull little pieces from what they have done, and make it your own.”

And then, you have to let the fans know that it’s OK to try to use their phones in one of the nation’s oldest sporting facilities.

“We want people to know the network is there, and we’re going to actively promote it,” Doherty said. “We’ll have signage and we have a good greeting services staff who will be armed with the information on how to get on the network. We’re going to do everything we can to get people connected.”

Stadium Tech Report: An MSR Geek Sneak Peek finds fast Wi-Fi, lots of cell antennas at Levi’s Stadium

The historic idea that big, open-air stadiums are bad places for wireless connectivity may have finally met its match. Though it still needs a test when it’s full of fans, a sneak peek at the incredibly robust Wi-Fi and distributed antenna system (DAS) deployments in the San Francisco 49ers’ new Levi’s Stadium should mean, at least for Niners fans, that poor connections at football games are a thing of the past.

Granted, our tour of the new stadium during its ribbon-cutting ceremony Thursday wasn’t any kind of official unveiling of the much-hyped Wi-Fi and cellular networks inside. There weren’t any tech reps on hand, and there were many places throughout the building where it was clear that parts of the network weren’t yet turned on (along with many flat-screen TV mounts still waiting for their electronics). But just walking around inside the concourses and clubs, a trained eye could see Wi-Fi access points and DAS antennas just about everywhere you looked. And, wow — in areas where the network was live, the download speeds were off the charts — we recorded several readings of 60 Mbps or higher, including on the Levi’s sustainable-garden rooftop court.

On one hand, it’s fair to say that our walk-around tests don’t mean a thing, because the real chore for the Levi’s network is not to impress a few random guests, but instead to handle the huge loads brought on by a sellout crowd of 68,500 iPhone-toting football fans. Over the next month or so we’ll get some more chances for proof points, especially at the Niners’ preseason games, when we hope to see the ambitious on-demand instant replay app being put through its paces, while at the same time Niners fans use their phones to order food delivered to their seats. That’s a lot of potential bandwidth and interactions. But after our tour Thursday, we’re perhaps a bit less cynical than we were before about the network’s ability to handle such loads.

Designed for networking from the ground up

Why? Mainly, it’s the fact that Levi’s looks like the proof of what is possible when you design a stadium from the ground up with connectivity in mind. Though we could in fact see many, many exposed APs and DAS antennas, none were overly obtrusive — in fact, they all looked like they had been mounted somewhere that was expressly designed for them to be there. I’m no network engineer, but the simple lack of a lot of exposed cabling around those antennas and APs says to me that the guts of the building may be as smart as the network. Under one overhang I did see a cable run that reminded me of a data center — a wire basket carrying fiber, with plenty of room for expansion, leading into holes in the concrete that weren’t close to being filled. Again: I carry no union card. But if I can see such things and figure them out, it seems like a lot of thought went into the Levi’s network that’s perhaps not as obvious as the APs and antennas. Which, of course, is a great thing for administrators and even better for users.

What else did we see that was amazing, technology-wise? The sheer number of flat screen digital displays, especially when combined with the numerous large, comfortable lounge and club areas says to us that fans won’t miss much action even if they’re not in their seats. In the plush big-bucks clubs and even in the proletariat concrete concourses there was flat screen after flat screen (or at least the mounts where more TVs will be). It’s a simple but profound way to improve the fan experience, maybe a lesson learned from Candlestick, where fans congregated outside the few concession stands with TVs just to watch replays. Sure, the phone app may be one way to get there but my take from walking through Levi’s is that if you want to stand around and enjoy a beverage with friends you will still be kept up on the action even if your phone’s in your pocket.

Like we said — there is certainly more detailed information to come, and we are betting that the folks at Aruba Networks (the Wi-Fi gear supplier) and DAS Group Professionals (the neutral third-party DAS host) are chomping at the bit to talk about their deployments… let the free advertising of the antenna pictures below suffice for now. Though it’s just the start of our planned Levi’s Stadium network coverage, it was an impressive one, right down to the glasses of Iron Horse bubbly served at the post-ribbon-cutting reception. Salut, Levi’s and Niners!

Even at a new stadium, getting the wireless network right is a constantly changing target. And for 4-year-old Target Field in Minneapolis, that meant an upgrade to the DAS not too long after the facility opened its doors.

“Nobody will ever have the perfect [network] install, and that’s part of the fun of it,” said John Avenson, vice president of infrastructure for the Minnesota Twins baseball club, in a phone interview with MSR. “The problem is not solvable as in, one year and you’re done. You need to be continuously improving.”

For the Twins, improving cellular connectivity was especially important since this year the club and the stadium will host baseball’s midsummer classic, the All-Star game. Thanks to help from InSite Wireless and DAS gear from TE Connectivity, Target Field’s DAS should be able to handle not just the overall growth in Twins fans’ wireless needs, but also the extra demands of a special event and all the selfies that go along with it.

“Fortunately, InSite and the carriers have been able to react quickly, and we should be ready for the test of the All-Star game,” said Dan Starkey, director for ballpark development and planning, in the same interview. “We’ll be ready to fully test the system.”

Wi-Fi and DAS, a perfect double play

As a new facility, Target Field was ahead of the curve when it came to Wi-Fi. On opening day the park had free Wi-Fi service for fans, with 225 access points initially available. “Back then that was a big number,” Avenson said. And while some carrier execs have been voicing an opinion that DAS is all that’s needed in a stadium, Avenson isn’t convinced.

“At this point you need both Wi-Fi and DAS,” he said.

Though the Twins do a good job of promoting the Wi-Fi service, most fans in stadiums everywhere usually default first to a cellular connection, either because they don’t know about the Wi-Fi, or don’t want to be bothered with the process or aren’t sure how to connect. Since people still think they should be able to send pictures or watch videos over a cellular connection, even at a crowded ballpark, that means the DAS – the Distributed Antenna System – needs to keep pace with all the smartphones and tablets being used.

“Some fans put their phones away [when they come to the stadium] but the younger crowd does not do that,” Avenson said. “Nothing interrupts their need for a good [wireless] experience.”

AllstarlogoAccording to Avenson, even before the facility opened the IT team new that they wanted a neutral host partner to lead the DAS effort.

“It just made sense to us,” said Avenson of having a neutral host DAS supplier, since as he said, carriers can be like siblings who have to share a bedroom. “InSite really enables the carriers, so they don’t have to fight with each other [over technology deployments].

Verizon Wireless and AT&T, the two biggest cellular carriers in the U.S., were on the neutral host DAS at the start, and were later joined by Sprint and T-Mobile. And even though the park is fairly new, Avenson said everyone involved realized quickly that wireless demands were growing, meaning that an upgrade was needed sooner rather than later.

According to the team, the most recent upgrades were to add MIMO capability for 1900 and AWS 2100 MHz bands, as well as adding four additional sectors in the bowl for AT&T. The new DAS can also support newer 4G LTE technologies, the Twins said.

“It’s just part of the evolution of DAS,” said Starkey. “Once we realized we needed additional coverage and capacity, InSite and the carriers acted quickly.”

The downtown difference

Like many other stadiums and large public facilities, Target Field had to be creative in finding space for the DAS head end equipment.

“In 2008 and 2009, we thought we’d fit it [the DAS head end] in a corner but it grew to a larger space and then that wasn’t big enough,” said Avenson, who added that AT&T and Verizon each have 10 to 12 cabinets of back-end gear for their DAS operations. “When the building was being built in 2008, the architects were not aware that we’d be needing more space. It’s amazing how much space and power a DAS takes at the head end.”

Adding to the complexity of the Target Field deployment is the fact that the field is in the middle of downtown Minneapolis, with large office buildings peeking over the roof of the stadium. According to Avenson, carriers and the team had to perform a series of reconfigurations to antennas both inside the park and out, so that the macro metro cellular network didn’t interfere with the DAS network inside the stadium.

“When the macro network wants to invade [the stadium] you have to push the macro network out,” said Avenson. “If you’re Miller Park [the baseball field in Milwaukee] and you have a big parking lot around the stadium you can control your own destiny. Parks in the middle of cities have a much different challenge.”

Report excerpt: At Bat app driving the MLB digital experience bus

Editor’s note: The following excerpt from our MLB technology deployment analysis comes from our Stadium Tech Report for Q2 2014, which includes a wealth of information, research and analysis about the stadium tech marketplace. With a focus on Major League Baseball technology deployments, the report is available free for download so get your copy today. Enjoy the excerpt that follows.

At Bat driving the application bus

If there is one other thing that defines MLB’s digital advantage, it’s the league-wide requirement to use the MLB.com’s At Bat app as the only in-stadium app offered by every team. Though there is some grumbling heard from time to time from teams who want to innovate at a faster pace, for these early days of digital in-stadium experience having At Bat as a base is most likely a huge bonus, since it makes it easier for fans to learn how to find and use the features, no matter which stadium they are in.

Though we here at MSR are more in favor of an eventual open infrastructure – say, a package of MLB-approved APIs that third-party developers could use to bolster the At Bat ecosystem – in these days when fans are still learning how to connect to Wi-Fi and are still getting familiar with the idea of using their phones to purchase in-game seat upgrades or to order concessions, it’s probably not a bad idea to limit choices.

The interesting thing to watch may be to see if, in a few years, MLB has metrics to back up its all-for-one strategy, or whether the MLB digital team decides (like Apple and the iPhone) that opening up the platform could lead to more innovation. The good news for fans is, with better connectivity and more apps, going to games should be easier and more fun as time goes on.

DAS upgrades are good news

Maybe the best news on the DAS front is what seems to be (finally) some benefit from the always-improving pace of technology – accord- ing to several teams we’ve talked to recently, a pleasant surprise that comes about during DAS upgrades is the fact that head end equipment footprints are actually decreasing, meaning that the space crunch often caused by DAS may be easing somewhat.

Of course, some of those space savings may be eaten right back up by additional carriers joining in, or by existing carriers adding more coverage support. A continued issue that we will keep watching is whether or not more teams and stadium owner/operators choose neutral third- party hosts for their DAS, or whether they trust that a single carrier will be able to balance the needs of all. In our interview with AT&T’s John Donovan for this issue he said that he doesn’t think any carriers want to use DAS deployments as a strategic advantage over others; we will track your stories and what happens in the wiring closet to see if his opinion reflects reality.

John Donovan: The ‘network chief’ talks about AT&T’s successful stadium strategy

In a strategy borne by necessity, AT&T has become far and away the leader in deploying distributed antenna system (DAS) technology in stadiums and other large venues across the country. In a recent phone interview, Mobile Sports Report spoke with the man behind the plan, AT&T senior executive vice president John Donovan, who told us the hows and whys behind AT&T’s DAS strategy, and how AT&T is continuing to innovate to improve DAS performance. Donovan also offered some interesting insights about large-venue wireless consumption patterns, based on AT&T’s thorough and varied operator experience, which is likely second to none.

With 670 DAS systems deployed in large venues, including 150 in the past year, AT&T has no plans to slow down. In fact, Donovan said AT&T will deploy another 250 DAS systems this year, adding to its impressive totals for presence in large public venues. According to Donovan, AT&T DAS systems are currently active in 75 percent of the “big 4” professional sports venues in the U.S. (football, baseball, basketball and hockey), a list thaat includes 90 percent of NFL stadiums. AT&T also has DAS deployments in a large number of top college stadiums, making Donovan confident that his company is far and away the top provider of enhanced cellular services in stadiums.

“We are absolutely crushing the competition on performance in venues,” said Donovan, who 5 years ago spearheaded a move inside AT&T to create a team that specifically targeted large public venues. Now, the fruits of that team’s labors are paying off.

Building the DAS group

The several-hundred strong group, which Donovan said included employees with experience in tower rental operations, building right-of-way negotiations, and “young, aggressive wireless” technicians, had a mandate, he said, to target all the premium venues in the U.S., and get them a world-class wireless architecture.

“The objective was, to wire them all, really,” Donovan said. Armed with a large budget (“in the early days, it was ulimited,” Donovan said), the group started ranking every large public venue, calculating stats like “seat minutes,” a value of how often a seat in a stadium would be filled.

“The Staples Center [in Los Angeles] blew everyone away — one year they had 367 events,” said Donovan.

The main reason why AT&T had to improve cellular connectivity at large venues had to do mainly with the company’s legacy as the initial, exclusive carrier for the Apple iPhone. Though Verizon Wireless and other carriers eventually got access to the iPhone in 2011, AT&T’s early lead meant that many iPhone owners were still AT&T customers — and according to Donovan, the kind of people who bought iPhones were also the kind of people who went to sporting events and concerts.

“In the early days, we were the only ones with the problem [of congestion in arenas],” Donovan said. “If you take the demographic of an event, and map it to the demographic of an iPhone buyer, you get a big overlap.” While AT&T may have only had 30 percent of the overall wireless market share, in some arenas Donovan said AT&T’s “internal” market share could represent as many as 75 percent of the fans in attendance.

In those early days of a few years ago, with many of AT&T’s iPhones still using older 2G and 3G technology, making them work in crowded arenas was a challenge, Donovan said.

“We were really forced to innovate around architectures and manage RF [radio frequency],” Donovan said. “We got really good at design.”

Fast-forward to 2014, and the team is in a much different space, innovating ahead of the curve instead of scrambling to respond to pressures. One example of the new thinking is the debut of some large, spherical antennas that AT&T used at the Coachella music festival in April.

“We had this huge thing that looked like a human-sized bowling ball with 12 [antenna] sectors in it,” Donovan said. “We’ve got a 20-sector version coming out next year.” AT&T in the last couple years has also debuted antennas that allow the carrier to focus signals into smaller geographical space, to better target the packed crowds in arenas and large venues.

“We’ve gotten a lot better at design,” Donovan said.
