All those predictions about Silicon Valley people using a stadium network more than other fans? It looks like they’re true.

The network numbers are in for the first football game at Levi’s Stadium, and they are pretty amazing: According to Dan Williams, the vice president of technology for the San Francisco 49ers, the Levi’s Stadium Wi-Fi network carried 2.13 terabytes of data during last Sunday’s preseason game, with a peak of 24,775 fans on the Wi-Fi network at the same time. Those numbers are comparable to the latest Super Bowl at MetLife Stadium in New Jersey, where according to AT&T and Verizon there was approximately 2.5 TB of data used on wireless networks.

The kicker to the Niners’ stats — they do NOT include any traffic figures from the Levi’s Stadium DAS, the distributed antenna system that is meant to provide enhanced cellular coverage in the stadium. What follows is an email Q-and-A with Williams, who kindly answered our extensive list of questions. The real question is, if Niners fans are hitting terabyte levels during preseason games, what’s going to happen when the season starts for real? And the instant replay function in the team app is live? Read on for some great insight from Williams. Additional editor’s note: The companies talked about include Aruba Networks, the provider of Wi-Fi gear; Brocade, provider of back-end networking gear and integration; DAS Group Professionals, the integrator and deployment team behind the DAS (the network of small antennas that improve in-building cellular coverage).

Mobile Sports Report: what was the peak number for simultaneous Wi-Fi connections? The average?
Dan Williams: We peaked at 24,775 (roughly 38% of attendance) concurrent connections with an average of 16,862 (roughly 25% of attendance).

MSR: When did connections spike? When did they start and then tail off?
Williams: We had two spikes, 1:02 p.m. [editor’s note: kickoff was 1 p.m.] with a system wide peak of 2.3Gbps and then again at 1:53 p.m. with 1.7Gbps. We averaged more than 1Gbps for more than two hours.

MSR: What was the total data tonnage on the Wi-Fi network?
Williams: We offloaded 2.13 Terabytes during the event.

MSR: What were the usage patterns with the app — which feature did people use most?
Williams: We had a great deal of usage throughout Sunday. The food ordering app usage was top of the list with ticketing being a close second while video would take third from a feature standpoint.

MSR: What are the plans with the instant replay feature… when will it be live (and can you explain why it was held back)?
Williams: We felt a lot of folks were happy with the livestream, so we wanted to focus more on a couple of core features with food ordering and ticketing a bit more at this point. Replays will be available to all by the first regular season home game.

MSR: Can you explain exactly how the location feature works… does it require Bluetooth to be on?
Williams: The location service is mainly built around low-energy Bluetooth, BLE. We have a number of beacons placed throughout the open areas and points-of-interest which allow the app to identify your location through proximity. Aruba helped us build this as well. GPS is also used but the primary resource is Bluetooth. The app prompts users to enable Bluetooth to provide improved location awareness.

MSR: Can you provide any stats on the DAS performance?
Williams: The DAS held up really well. Like WiFi, we found some areas that need tuning. Unlike WiFi, the carriers protect a lot of their specific data but they have told us they are very happy with the system DGP helped us with. It is important to note our DAS and WiFi have been built to compliment each other and I think between Aruba and DGP, we did that very well. Most come here looking to connect to WiFi but our story internally has been we are going to have an awesome connectivity play regardless of medium.

MSR: Could you guys see any [more] of the 2.4 GHz issues like the one I had?
Williams: As you know, 2.4GHz is limited with non-overlapping channels so we suspect a number of legacy devices may have some problems. That said, we had a ratio of 2:1 with respects to 5GHz to 2.4GHz [usage] which shows a good deal of 2.4GHz usage. We know we still have some optimizations to do in the upper bowl and upper concourse while we continue to fine-tune the main bowl and concourse as we noticed our cell edge was weaker than expected when the stands were full. Our Aruba team did a great job capturing real-time data during the event as there is really no other way to test this stuff without a full venue. We will make some tweaks and continue to learn more from every event we host. Between Aruba, Brocade, and the 49er tech staff, we are not resting on our laurels. We know there is more to do.

Dallas Cowboys, AT&T add more tech to AT&T Stadium, add fuel to ‘most-connected stadium’ debate

AT&T Stadium, North Texas, USA

AT&T Stadium, North Texas, USA

During last Sunday’s first “real” football game at Levi’s Stadium, I was asked several times if I thought the San Francisco 49ers’ new home was the “most connected” venue ever. I hesitated and hedged my answer a bit, because when it comes to wireless networks and tech innovations I think AT&T Stadium — home of the Dallas Cowboys — needs to be mentioned in the same sentence as Levi’s.

This week AT&T and the Cowboys announced more enhancements to AT&T Stadium’s already powerful network, and a new toy for fans to interact with. First on the network side, AT&T said from last summer until now it has increased the capacity of the stadium’s DAS by 50 percent, with 1,300 DAS antennas now in place. On the Wi-Fi side the stadium now has more than 1,500 access points, which may be the most in any stadium anywhere, to the best of my knowledge. (According to the Niners’ press guide, Levi’s has 1,200 Wi-Fi APs.) Throw in the big TV hanging from the center of the roof and AT&T Stadium has to be part of any discussion about “the most connected stadium” in football, if not in all of sport.

(I’d also include AT&T Park in San Francisco in that argument, which has somewhere north of 1,200 Wi-Fi APs in a much smaller venue; from what we hear the two AT&T-sponsored stadiums have a friendly competition when it comes to tech deployments.)

On the new-toy side it should be fun to see the new 130-foot “AT&T Fan Experience Board” in action — according to AT&T and the Cowboys this contraption is built of 40 mirrored louvers which can rotate in sync, and can show ads, fan pictures and will also be part of what the team and AT&T are calling the “Unite this house” feature on a new fan app. We’ll let the Cowboys blog explain how this will work, on plays where Tony Romo is throwing to teammates instead of to opponents:

The “Unite the House” fan interaction feature on the app will alert fans at pivotal moments of the game through their mobile devices. As the stadium app vibrates, a message will be displayed providing the particular context and immediacy of the action. Fans will be guided to unlock their phones, hold their fingers on the Dallas Cowboys star and as more phones power up, the stadium will be full of strobes, not only from mobile devices, but also on the ribbon displays and the HD video board. The visual will gain intensity and speed as more fans join in, energizing the stadium and culminating in a final eruption of light and motion provided by the louvers that will canvas the entire stadium.

AT&T and the Cowboys also announced some large interactive screens — the Cowboys blog called them “life-sized iPhones” — where fans can swipe to learn more about Cowboys players, or Cowboys cheerleaders. Our guess is that both will be immensely popular. At Levi’s, there are some interactive displays and features — one, sponsored by Yahoo!, asks fans to answer trivia questions. While it’s neat to see these things emerge, I wonder if instead of fluffy features some interactive boards could be converted into things that could help you — like with stadium maps, or an app that would let a phone-less fan send a message to someone else’s device. Our guess is that you will see more, not less, of these interactive screens in the near future.

If nothing else, the Cowboys and AT&T seem to be showing that even off the field, the NFL is a competitive league — we will be interested to see how the technology deployments at other stadiums, like Jacksonville, play out. Look for more coverage and anlysis in our upcoming Q3 Stadium Tech Report issue, which will focus on… football. AT&T technology photos to follow.

Extreme, YinzCam team up for Baylor Wi-Fi and app deployment

Screen shot of proposed Baylor app

Screen shot of proposed Baylor app

When the new $260 million McLane Stadium at Baylor University in Waco, Texas, opens for this season it will have full-facility Wi-Fi and a custom mobile app, designed and deployed by a partnership between Wi-Fi gear and analytics provider Extreme Networks and app developer YinzCam.

In an announcement today, Extreme and YinzCam said fans in McLane Stadium will have access to real-time replays via the team’s new app, a functionality made possible by high-quality Wi-Fi. The network and app are expected to be live for the Baylor Bears’ first home game of the season, an Aug. 31 date with SMU. The stadium will also have a distributed antenna system (DAS) hosted by AT&T; according to Baylor, Verizon Wireless has already agreed to participate in the AT&T-hosted DAS.

While we are working on setting up an interview with the Baylor folks to hear more about their new stadium in general and their network in particular, here are some of the prepared quotes from the participants:

Pattie Orr, Vice President for Information Technology, Baylor University:

“2014 is a monumental season for Baylor University and Baylor Athletics as we officially open McLane Stadium and deliver our fans the ultimate fan experience. Using a hand-picked collection of innovative technology, Baylor fans will stay connected with the ultra-fast Wi-Fi network as well as a robust cellular distributed antenna system. Fans can direct their own mobile experience using our new Baylor In-Game application throughout the stadium.”

Norman Rice, Senior Vice President of Business Development, Extreme Networks:

“Baylor University is one of the pre-eminent academic and athletic institutions in the country and has put together one of the most exciting experiences in sports with the debut of McLane Stadium. Extreme Networks is proud to let our wireless technology extend the connectivity that fans and media consider a ‘must have’ whenever they attend a game.”

Priya Narasimhan, CEO and Founder, YinzCam:

“This is a major first in college sports. The Baylor In-Game App is pushing the envelope by being the first college athletics app to provide instant replays from multiple views to Baylor fans, right at their seats, at the new McLane Stadium.”

Stadium Tech Report: Levi’s Stadium network lives up to hype, but team app still needs work

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: Minnesota Twins tap InSite and TE Connectivity to get DAS ready for All-Star Game

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.”
