Sure this is an AT&T ad. But an ad about putting in DAS at a stadium? Who would run a copy of this except us? Enjoy all you antenna geeks out there. And… there’s gotta be work for the fan, maybe conduit work? C’mon DAS dudes, let me in on the fun!
You had me at “Do you know how to optimize a 9-beam multi-beam antenna system?”
Inside the bowl at American Airlines Center
Last week his team’s home facility, the American Airlines Center in Dallas, formally took the wraps off a powerful new Wi-Fi network. Built by AT&T using 315 access points from wireless gear provider Aruba Networks, the new American Airlines Center network should be at the top of league-arena networks, even if the Mavs’ owner won’t be using it that much. But as he said (in the wake of a SXSW panel last week that was talking about Wi-Fi in stadiums), Cuban isn’t against Wi-Fi anymore. He just thinks you should do more on the floor so that fans aren’t watching their phones.
@Liz_Grow have to have wifi. But you should do everything possible to give people no reason to use it

While Cuban’s points about wanting to keep fans engaged with the game instead of looking down at their phones are well-taken, the reality of an always-connected world is that good connectivity is always in demand, especially at sporting events where fans may seek to use breaks to stay in touch with their digital worlds. And while the 21,000-seat American Airlines Center has had DAS installations for improved cellular, a robust Wi-Fi network allows for greater levels of connectivity, as well as potential future applications that might produce a better fan experience as well as more revenue.
“At some point, you just can’t live without it,” said Lori Glasser-Seinera, vice president of corporate sponsorships at American Airlines Center, in a recent phone interview. Cuban, she agreed, was correct in trying to prioritize the fan experience, but even he now agrees that Wi-Fi needs to be part of the stadium amenities. Joe Heinlein, IT Director for the arena, said that for many fans not having connectivity could be a reason to justify staying home.
“We need to make sure we fill our seats, and not fill the couch,” Heinlein said, in the same phone interview. A good network, he said, is one way of ensuring that fans don’t have a reason to stay home.
Moving from back office to fan-facing
Though the fan-facing Wi-Fi network (which AT&T makes available for free to all attendees) is new, there has been an Aruba-based network in the facility for more than several years. According to Heinlein, the network vendor approached the arena in 2005 “with an incredible offer” to put in a Wi-Fi network for back of the house business operations.
“We’ve used it for internal operations, for the press, and in meeting rooms,” said Heinlein of the 40-AP network that went unseen by fans of the Mavs and the NHL’s Dallas Stars, who also share the building. (American Airlines Center is owned by the city of Dallas, which leases it to the Stars and Mavs.) But 2 years ago, Heinlein said the arena started talking about how to put fan-facing Wi-Fi into the facility, a discussion that involved Dallas-based AT&T, a longtime sponsor for the arena.
“Since Aruba had been a longtime partner of ours we requested that AT&T include them in the deployment,” Glasser-Seinera said. The final result is the new Wi-Fi network announced last week, one where AT&T will use advanced Wi-Fi technology to automatically log in AT&T customers. Other carriers’ customers can also use the network, after logging in through a separate process. Heinlein said the network was a joint project between the arena and partners including AT&T, and as such did not divulge the total costs of building the new network.
Aruba gear helps overcome changing network needs
With more than 200 events during a calendar year, American Airlines Center is a constantly changing venue (think circuses, and concerts), especially when it comes to network coverage. Heinlein said specific challenges to connectivity include the large open space in the center of the arena, as well as the need to extend coverage deeper into the floor for basketball games.
“We have a big hole in the center of the arena, and there’s not a lot of places there to hang [antenna] assets,” Heinlein said. A “good portion” of the APs are located beneath seats, Heinlein said, along with some other ones that are located in vertical risers, which had holes bored into them for that purpose.
“It’s always a challenge to get a signal where you need it,” Heinlein said.
For basketball, the seating plan moves farther out onto the floor than for hockey games, a factor that often has the arena’s IT team being creative in deployment strategies, like putting access points on top of mobile tripods to provide extra coverage.
“The people sitting close to the court are very important customers,” Heinlein noted. “One of the reasons we went with Aruba is that their APs lend themselves to being able to make quick changes, and we use that capability.”
Looking to the future, with a network now in place
Cuban’s opinions about replays not working well on cellphones may keep the Mavs from being on the cutting edge when it comes to stadium apps. But that doesn’t mean the arena will be sitting still when it comes to utilizing its new resource. According to Heinlein and Glasser-Seinera, there are many potential new avenues to explore when it comes to using robust in-building connectivity. One such idea is using Wi-Fi as a GPS type system, to help attendees find resources inside the building more quickly. In the past, such applications could only be dreamed about. Now, they can be tested in the real world.
“Now that the system is in, we can test it and try different things,” Heinlein said. “Now that it’s here, we can explore what’s possible.”
We’d heard this project was underway but now it’s official: AT&T and Aruba Networks are the forces behind a new Wi-Fi network at the American Airlines Center in Dallas, a 21,000-seat facility that is home to the Dallas Mavericks of the NBA and the Dallas Stars of the NHL.
According to an AT&T press release put out today the new Wi-Fi network will have 315 access points, bringing more connectivity to the AT&T DAS that has already been in place at the arena since 2012. For AT&T customers the network should be fairly simple since the company is supporting automatic authentication, which means no logins or setup screens. Fans who have phones from competing providers will also be able to use the network for free, after visiting a login page.
We haven’t yet been able to talk to AT&T folks or the IT department at the arena, but look for a Stadium Tech Report in the near future. We do know from reporting on our upcoming quarterly long-form Stadium Tech Report that the people running the arena weren’t making any small plans, so it will be interesting to hear about the breadth and depth of the deployment. From a business perspective it’s a big win for Aruba, especially since pairing with AT&T could lead to more stadium deals down the road.
It’s also always interesting to hear about AT&T getting behind a Wi-Fi deployment, since the company can often seem of two minds about Wi-Fi in stadiums. From the sounds of it, this is one of those “big name” deals where AT&T likes to get involved from the bottom up — and since it’s in AT&T’s home turf it makes sense that AT&T would want a big part in any wireless deployment close to its corporate offices. Here’s a quote from the press release:
“Providing Wi-Fi at premier venues like American Airlines Center is part of our strategy to mobilize everything for our customers,” said Aaron Coleman, AVP, AT&T Wi-Fi Solutions, in the AT&T press release. “By working with stadium venues to strategically design and deploy an in-stadium network we can satisfy the connectivity demands of the business and enhance the way teams and venues engage with their fans.”
As we said, we hope to have more details soon so stay tuned.
pCell antenna from Artemis Networking
Fronted by entrepreneur Steve Perlman, perhaps best know for his development of things like QuickTime and WebTV, Artemis claims to have solved one of the most vexing problems for large public-venue wireless, namely the congestion caused by a lot of cellular devices in a small geographic place. Though no details are yet available to explain exactly how it works, the company says its pCell wireless technology turns conventional cellular infrastructure on its head, using cell interference to amplify signals to each device.
We are reaching out to the company and to other cellular industry types right now to get reactions to the announcement. In the meantime, if this plan really works it could potentially make stadium and other large-venue wireless networks a lot easier and cheaper to deploy. Some good details can be found in this EE Times report.
Here is the company’s simple explanation of what its technology does:
“pWave radios transmit signals that deliberately interfere with each other, combining to synthesize tiny pCells, each just one cm in size. Every mobile device has its own pCell, a “Personal Cell,” each getting the full spectrum capacity.”
A little bit farther down its explanation page, the company adds more details, apparently pegging its strategy of mesh deployment of antennas as a cloud-based radio access network, or C-RAN.
“pCell is a pure software-defined radio C-RAN. Linux-based servers scale linearly with capacity. Fronthaul is conventional IP. pWaves self-synchronize. Seamless handoff to cell networks if desired.”
And just to tease more, the company also hints that it could set up its own networks, instead of just making cellular work better. Again, we will need more technical details about how pCell works to figure out its exact impact, but this statement is also interesting:
“Concurrently with LTE devices, pCell supports “pCell-native” devices, at far lower cost and power, each with its own pCell in the same spectrum. pCell-native devices can be faster than LTE with fiber-class latency. For example, an iPod-class device could be made pCell-native with minimal additional cost at the same size and power, and would provide better than LTE mobile performance in pCell coverage areas. This opens the door for low-cost pCell-native smartphones, wearables, UltraHD TVs, laptops, appliances, etc.: a broadband Internet of (inexpensive) Things.”
Our guess is that the reality of this design will mean some kind of client software or chip necessary to allow devices to connect to the pCell network; anyone with any details on the device or network, please chime in!
Inside the AT&T head-end building at MetLife. Cables! Credit: AT&T
Part of the gain no doubt came from the fact that MetLife Stadium holds approximately 10,000 more fans during a football game than the Superdome, 82,566 to 72,003. But AT&T’s numerical evidence — including a new peak-time high of 119 GB during the hour before kickoff — shows that the desire to access mobile devices inside stadiums is still growing, especially at big games like the Super Bowl.
Verizon Wireless, which like AT&T spent more than a year getting MetLife’s network ready for Sunday’s game, also said it had experienced record traffic on its networks, claiming a total of 1.9 TB of cellular traffic inside MetLife Stadium. During the game Verizon Twitter accounts said new traffic records were set before halftime; however we still have no figures from Verizon for previous years’ data for comparison.
Total VZW data usage in-stadium Sunday more than 1.9 TB – highest data usage we’ve ever seen at aSuper Bowl @VZWNews http://t.co/DG0HvVTKDz
— Tom Pica (@VZWtom) February 3, 2014
Verizon also claimed its peak hour usage was “800 percent” greater than last year’s, but again, we don’t have exact numbers so can’t confirm the accuracy of such claims. Still unkown is how much traffic was carried by the stadium Wi-Fi network which Verizon manages (and was free to all MetLife fans), since Verizon did not provide Wi-Fi traffic numbers. Our guess is it saw similar traffic leaps as AT&T’s and Verizon’s cellular nets.
Another interesting note from the AT&T data is a trend toward more mobile data use, and fewer voice calls. Fans at the game Sunday made 55,000 voice calls on AT&T networks, down from 73,000 calls in 2012. Some of that might have to do with the fact that last year’s game had a lengthy power outage, which no doubt prompted many “I’m OK” calls to loved ones. But still — a 20,000 call dropoff in the face of more than doubling data traffic seems to show that people are using their phones more, even if they are talking less.
In case you are wondering why you won’t be able to watch the Super Bowl live on your phone while you’re at the game, Jon Brodkin at Ars Technica has a good story about why the NFL is blocking streaming video inside MetLife Stadium. To quickly recap, NFL CIO Michelle McKenna-Doyle told Brodkin that streaming video takes up too much bandwidth, and that it could hamper overall wireless communications on game day, so the league is proactively blocking live feeds at the game.
While I agree with her assessment of the situation and the solution (blocking live video), I don’t agree with her claim that the “vast majority of our fans want to watch the game on the field, watch the replays on the jumbo board, and participate in the event more than they want to be checking their phone,” and I’m surprised that Brodkin didn’t put up more of a challenge to this claim. Her follow-on claim that the league is doing the “vast majority” a favor by blocking the few video viewers rings hollow and reminds me of the old “data hogs” arguments the carriers used to use against people who were exercising their rights to their unlimited data contracts. My point: don’t blame fans who want to watch live video as being the people ruining the network for everyone else. Put the blame where it deserves to be, namely on the in-stadium networks that can’t yet handle the demands of a large crowd that wants video at the game.
We’ve talked before about why people want to stay connected while at the game. It’s not for everyone, but the desire to be online in your stadium seat is way more widespread than just a few people. Trolls will comment and say “watch the damn game and shut up” but plenty of real sports fans want the replays and closeups they are now accustomed to on TV. And not every seat has a good view of the big screens inside the stadium, and many times those things are showing ads, not replays. Then there is the time standing in line for a beer or bathroom. Why shouldn’t you be able to watch the game you are paying big bucks to be at, instead of being penalized because the stadium doesn’t have enough beer vendors or urinals? How about watching a replay while the game is in one of its lengthy TV timeouts? Or catching up on a play that you missed during halftime? Isn’t just having to listen to Bruno Mars punishment enough?
It will be interesting to see what the user statistics are like when the San Francisco 49ers’ new Levi’s Stadium opens this year, if its much-touted network delivers as hoped. The cynic in me is also guessing that when the NFL finally gets its digital video strategy figured out — meaning they clear the rights contracts and find a way to start charging fans more to watch more video online — the stadium network problems will suddenly be solved, and you’ll be able to watch all the live video you can afford.
We’ll be the first to acknowledge that putting networks in stadiums isn’t easy. Our recent Stadium Tech Reports series is designed to profile those in the industry who are trying to bring a quality wireless experience to their fans, so that others may follow. Already, we see places like Barclays Center and Gillette Stadium pushing the envelope when it comes to features like streaming video. In many ways, getting there is a long road that we’re just at the start of. If there is one bit of analysis I can provide after covering this field for the past 3 years, it’s that I don’t think anyone has gotten the stadium-network thing completely figured out just yet — and that any network put in over the past couple years is probably already in need of an upgrade, due to user demands already exceeding capacity. And that’s before most places are even thinking of providing live video feeds.
So sure, go ahead and block live video if it’s going to crash the network. But stop saying it’s something that just a few fans want, because there’s no proof behind that idea. Until the league and carriers like Verizon offer up real data on stadium network usage, there’s no way of telling exactly how many people at a game want to watch video, and whether it’s just for a replay or two or if they want a constant stream going at their seat. I’d be willing to bet more than a pint with McKenna-Doyle that if she polled an average NFL crowd and asked them if they’d like replays at their seats, a “vast majority” would vote for replays on their phones, and not in favor of settling for jumbotrons and PA announcers as she claims. So again, if you need to block the video, fine, but put the blame for the action on the network’s lack of capacity, and not on the fans who are just trying to enhance their own experience.
