Today’s news that DirecTV has signed a $12 billion deal with the NFL — priced at $1.5 billion a year for 8 years — to keep carrying its Sunday Ticket package has me thinking: Are we on the verge of a battle royale between the country’s two biggest cellular providers over mobile access to NFL games?

I don’t think it’s hyperbole to claim that mobile access to sports content and live NFL games are two of the hottest things going. Go look up any list of the most-watched live TV shows, and you will find various big NFL games dominating the list. Add that to stats like today’s news out of ESPN where the worldwide leader claimed it had 61.3 million unique mobile users during August and you can perhaps see another reason why AT&T might want to buy DirecTV: Because with Sunday Ticket, AT&T has a possible way to trump Verizon’s stranglehold on smartphone access to live NFL action, which it now shows via its exclusive contract with the NFL for its NFL Mobile app premium service.

Judging by traffic and search terms on our humble little site, people looking to find ways to watch live NFL action on their mobile devices is a pretty hot topic these days. Right now, the only way for most people to see any live action at all on a smartphone is to be a Verizon Wireless subscriber, and have the premium service for the company’s NFL Mobile app. Free to “More Everything” data plan customers and $5 a month for others, the premium NFL Mobile package provides access to Sunday night, Monday night and Thursday night games, as well as local Sunday games.

Sunday Ticket vs. NFL Mobile?

You can also watch the RedZone channel via NFL Mobile, but confusingly if you are on the More Everything plan you need to pay an additional $1.99 a month, a new process that helped mess up Verizon’s NFL Mobile access earlier this season. Non-Share Everything customers who pay the $5 a month fee have RedZone included for free. (For many true NFL fans, RedZone is often even better than having games streamed, since you get all the best action, even from blacked-out games or games not televised locally.)

Screen Shot 2014-10-01 at 2.37.08 PMWhere the battle might be joined is in the tablet space — since Verizon’s $1 billion agreement with the NFL only provides live game access to “phone-like devices” and not to tablets or computers, it will be interesting to see what happens if and when AT&T becomes the new owner of DirecTV. One of the more interesting options from DirecTV this year was the NFLSundayTicket.TV option, which allows a type of “cord-cutting,” providing all the options of Sunday Ticket without having to have satellite service. Right now the option (pricing starts at $199 for the season) is only available in a few cities, universities and apartment buildings, but with the heft of AT&T behind it who knows what might happen to both that deal and the regular Sunday Ticket package.

Though far pricer, the $329.94 Sunday Ticket Max plan offered by DirecTV currently allows for mobile viewing of all games, on “computer, tablet, phone or game console.” Anyone else see the possibility of AT&T offering free Sunday Ticket plans to purchases of new phones or tablets?

Verizon, which provides information about NFL Mobile subscriber stats just like Bill Belichick provides deep insights on the inner machinations of the New England Patriots, has not recently stated how many subscribers it has on the NFL Mobile premium package. But for $1 billion over 4 years you can bet the number of users is well into the millions, maybe even more than 10 million — and the exclusivity of NFL live action has certainly been a big selling point for Big Red. The good news for NFL fans is, if any battle begins, it will likely include more access for lower costs — that’s the kind of competition we can all cheer for.

Niners’ home opener tops Super Bowl for Wi-Fi data traffic with 3.3 Terabytes

The first regular-season home game for the San Francisco 49ers in their new home, Levi’s Stadium, produced more Wi-Fi traffic and far more actual fan-to-network connections than the most-recent Super Bowl, according to statistics from the Niners’ tech team.

Dan Williams, vice president of technology for the 49ers, said the Levi’s Stadium Wi-Fi network carried 3.3 Terabytes of data during Sunday night’s game between the Niners and the Chicago Bears, topping the 3.2 TB mark reported from Super Bowl XLVIII in February. According to Williams, out of the 70,799 that filled Levi’s Stadium Sunday, more than 30,000 fans connected to the Wi-Fi network at some point, with peak usage of 19,000 fans all connecting at one time occurring just before the 5:30 p.m. local time kickoff. According to the Super Bowl stats, the peak number of fans on Wi-Fi at that game at MetLife Stadium in New Jersey was 13,500.

“We’re pretty excited by Sunday,” said Williams, who said that the Wi-Fi network stood up well even under peak data transfer rates of 3.1 Gbps right before kickoff, and another 2.6 Gbps peak around 7:30 p.m. Around the peaks, network traffic stayed “well over 1 gig per second for three and a half hours,” Williams said.

During the Niners’ first preseason game against the Denver Broncos, the Levi’s Stadium Wi-Fi network carried 2.13 TB of data, and during the Aug. 24 preseason game against San Diego there was another 1.96 TB of Wi-Fi data. The figures do not include any reporting from the stadium’s DAS network, which carries cellular traffic from AT&T, Verizon Wireless and T-Mobile customer. If preseason games are any indication, Williams expects to see numbers in the terabyte range for DAS traffic as well.

The Wi-Fi numbers from Sunday showed that fans quickly figured out a name change in the network name (or SSID). During preseason games, the Wi-Fi network was identified as “Levi’s Stadium” in a device list of available networks; on Sunday the free stadium network used the name “xfinitywifi,” reflecting the brand of Wi-Fi sponsor Comcast. Some fans might have been confused since the “xfinitywifi” SSID is the same one used by Comcast for its public Wi-Fi networks.

“Some folks may have been scratching their heads,” said Williams. “We changed the name last Monday before the opener.”

Replay app gets 7,800 views

As previously reported by MSR, the instant replay feature of the Levi’s Stadium app had its debut Sunday, and according to Williams fans watched 7,800 replays via the app. The top replay view was of the early touchdown pass from Niners QB Colin Kaepernick to Michael Crabtree, which Williams said was viewed more than 1,000 times.

As MSR reported, the replay feature was somewhat limited in functionality, not working at all until late in the first half and then only offering the last two plays plus some scoring highlights for viewing. Previously, team executives had said the replay feature would offer multiple camera angles and multiple replay reviews all at the same time. According to Williams, more features will be added to the replay function in the near future.

“It’s not the finished product, by any means,” Williams said. “You’ll see some more polish on it.”

The most-used feature in the stadium app, Williams said, continues to be the food and beverage features, which allow fans to either purchase concessions for express line pickup, or to have their orders delivered to their seats. Williams said the Niners delivered 2,100 food orders to fans Sunday, the most for the Niners so far.

Perhaps the best news for Williams was the lack of complaints about the wireless network, which the team had asked fans to tweet about if they were experiencing problems. Though some fans with older devices that only work on the 2.4 GHz wireless bands might not see the same speeds as those with newer devices (which use the more roomy 5 GHz bands), Williams said his team only got a couple complaints about network issues, and one of those was solved before they could respond.

“Overall it just was a really good [wireless] experience,” said Williams, who always ends by noting that networks are never completely finished products. But with its Super Bowl-beating performance Sunday, the Levi’s Stadium network appears in midseason form.

“I think we’re close,” Williams said.

Stadium Tech Report: DAS Group Professionals makes a name for itself with Levi’s Stadium DAS

If you look around at the walls, ceilings and overhangs at Levi’s Stadium, it’s hard to miss the small square boxes with the off-white color and a “DGP” logo in one corner. While the wires hanging out the back of each box make it an easy guess that the equipment has something to do with wireless networks, even many industry insiders may not know the company behind the boxes and the three-letter acronym.

Meet DAS Group Professionals, the Bay Area firm in charge of deploying a distributed antenna system (DAS) to make sure your cell phone gets a good signal at San Francisco 49ers games and any other event inside the 68,500-seat Levi’s Stadium. And while you might not be familiar with DGP, rest assured the company is extremely familiar with cellular deployments for large public venues, having installed similar DAS networks for airports, casinos and hotels, and even for San Francisco’s BART train system. Of course, most of that work was done when the company was called Forza Telecom, before changing its name to DGP earlier this year, another reason why “DGP” may not have rung any bells.

“It may appear like we just fell out of the sky, but we’ve actually built quite a few [DAS] systems,” said Steve Dutto, president of DGP, in a recent phone interview. “We’ve got years of experience.”

DAS: The Rodney Dangerfield of stadium connectivity

One thing that keeps firms like DGP in the shadows is the relative obscurity of DAS itself. While most people generally understand how cell phones work — you turn on your phone, and it connects to an antenna somewhere on a tower or rooftop — in crowded public facilities like stadiums, traditional cellular networks with towers several miles apart can’t handle the concentrated capacity. To provide connectivity for areas with large crowds, the latest tactic is to deploy a DAS, a network of lots of smaller antennas. Originally deployed in places like office buildings, hotels and convention centers, DAS is rapidly gaining favor in stadiums and arenas, helping to alleviate the “no signal” problem that has cropped up in many venues the past few years.

And while stadium Wi-Fi gets lots of headlines whenever it gets deployed — probably thanks again to the widespread understanding of how Wi-Fi works — there are already far more DAS deployments in stadiums than Wi-Fi, mainly because cellular carriers will pay almost all the associated costs of a DAS buildout to make sure their customers get a signal. According to our most recent 2014 State of the Stadium survey, 71.4 percent of our respondents said they had a full DAS at their facility, while only 35.7 percent had fan-facing Wi-Fi.

How does a DAS work? Usually, either a major cellular carrier or a third-party “neutral” host like DGP will build out the antenna infrastructure, which includes many small antennas and then cables to bring the connections back to a wiring room or data center. There, cellular carriers install their own cell-tower back-end gear to authenticate customers and to provide a connection to the company networks and the Internet. Since it’s in the cellular carriers’ interest to keep their customers connected (and using billable minutes and data), carriers will often pay the full cost of a DAS infrastructure by building and running it themselves. In the case like Levi’s, where DGP is the “neutral host,” DGP builds the infrastructure and then charges cellular carriers to use it.

Such deals are rarely publicized, and Dutto would not comment on how much each carrier was being charged to use the Levi’s DAS — though industry gossip has the figure somewhere around $5 million per carrier per year. And just like fight club, for many deployments the first rule of DAS is that you don’t talk about DAS, because no cellular carrier ever wants to admit that its network might need help. So just like Rodney Dangerfield, DAS often doesn’t get a lot of public respect. But at Levi’s Stadium and many other sports and entertainment venues, DAS is a booming business that would be sorely missed if it wasn’t there.

The ‘dream and the nightmare’ of building the Levi’s DAS

Now that DGP’s 700-plus antenna DAS deployment is up and running at Levi’s, Dutto can breathe a small bit easier. While the network is good business for the company and an obvious prominent calling card for the future, the aggressive deployment timeframe probably isn’t something Dutto is eager to repeat.

“Levi’s Stadium was both a dream and a nightmare [for DGP],” Dutto said, due in part both to the Niners’ aggressive performance expectations and the rapid buildout schedule. Of course, DGP was somewhat used to working quickly with the Niners — when the company put a DAS in Candlestick Park back in 2012 to solve that stadium’s legendary lack of connectivity, Dutto said it was deployed “in about 90 days.”

The success of the Candlestick deployment, Dutto said, led to the Niners offering the Levi’s DAS gig to DGP. With it, however, came the need to match the team’s out-front statements about how the stadium was going to be the best ever in terms of wireless connectivity. And with many people not knowing or not bothering to switch their phones to Wi-Fi, the Levi’s DAS, like most stadium DAS deployments, would probably handle most of the wireless connections.

“We knew that it needed to be significantly better than anywhere else, right at the launch,” Dutto said. While the late addition of an early August soccer game at Levi’s pushed deployment schedules ahead even faster, Dutto said in the end it helped DGP overall.

“I wasn’t a big fan of getting ready for that date [the Aug. 2 soccer game was Levi's first event] but it was a blessing in disguise,” Dutto said. “The trouble with a network is that you can’t really test it until everyone shows up. We got some good data from that event.”

After the “daily and nightly” discussions with the Niners’ tech team about antenna placements and other matters, the DAS network performed well when it mattered, during the Niners’ two preseason games on Aug. 17 and 24. According to a traffic report from the stadium tech team, the DAS network carried a combined 1.02 terabytes of wireless traffic for the two preseason games, which is on par with activity seen at big events in the past, like Super Bowls. According to Dutto DGP’s internal tests showed that few, if any, calls were dropped or didn’t connect.

“We’re at 98 percent [network performance] already, without [the network] being fully optimized,” Dutto said.

RF challenges and too many iPhone 4 customers

While many of the stadium’s Wi-Fi antennas are well hidden — including the ones in boxes under seats — the DAS antennas are a bit more prominent, especially if you are near where the first overhang comes close to the seats.

“Unfortunately, with Levi’s exposed steel-beam construction, if you want the DAS to work, you’re going to see it,” Dutto said. “It’s hard to be stealthy in there.”

And in many cases there isn’t just one but instead two DGP antennas side by side, which reflects the company’s decision to actually build two parallel DAS systems to better accomodate more wireless carriers. According to Dutto, AT&T and T-Mobile are based on one system, while Verizon Wireless, Sprint and public safety communications are handled by the other one. Currently, all the carriers are live on the DAS except for Sprint, which is still in the process of installing its back-end equipment.

One of the biggest challenges for DGP, Dutto said, comes from outside the stadium, and not inside. Like other open-air stadiums located in city cores, Levi’s Stadium faces significant interference from cellular antennas on nearby office building rooftops, as well as from the Santa Clara Convention Center right across the street.

“Less than a half mile from Levi’s you can see seven different rooftop cell sites,” said Dutto, who said the flat, open terrain around the stadium increases the ability for those signals to interfere with the stadium DAS deployment. Target Field in Minneapolis had some similar problems with cell antennas on nearby office buildings.

“We’ve done a lot of work with the carriers to adjust their macro networks around the stadium,” Dutto said. “We’ll do more of that as we go, and expect it to get better.”

And while Levi’s Wi-Fi network has shown itself to be incredibly robust, Dutto said that cellular connectivity over the DAS might be even faster than Wi-Fi in many instances, especially if fans have later-model phones with 4G LTE.

Even though Dutto said DGP’s testing recorded download speeds of up to 200 Mbps — and 65 Mbps sustained — he acknowledged that many Levi’s patrons might never see those kinds of numbers unless they snap up some of the new iPhone 6 models introduced by Apple this week. According to network stats collected by DGP during the preseason games, a lot of fans may be ready for an upgrade.

“There’s a lot more iPhone 4 users out there than we thought,” Dutto said.

Verizon, NFL fumble opening-day live video for NFL Mobile app — for the 2nd year in a row

It’s not a streak you want to continue, especially if you are the NFL, Verizon Wireless, or one of the frustrated customers who weren’t able to see live video using Verizon’s NFL Mobile application during Sunday’s season-opening games. But just like last year, when activation servers for a new version of the app got overwhelmed, issues arose again on Sunday, making live video — one of the premium features of NFL Mobile that makes the app and service so attractive — unavailable for most of the day, including the large slate of early games.

Verizon executives who spoke with MSR Monday declined to comment on the NFL Mobile issues, instead referring all questions to their partner, the NFL media team. Verizon wireless support was also apparently offline on Sunday, leaving the task of responding to the many irate messages and tweets to the small but valiant NFL Mobile Support team.

Alex Riethmiller, vice president of communications for NFL Media, said the issue once again was due to high traffic overwhelming the authentication servers, which (putting it simply) identify whether or not a customer is a Verizon subscriber, and whether or not that customer has access to the premium content. Some of the additional traffic may have been due to two changes Verizon made in NFL Mobile subscriptions from last season; one was to give free premium access (which lets you see live action) to all customers on a More Everything data plan, and the other was to charge all of those More Everything viewers another $1.99 a month if they wanted to also watch the NFL’s RedZone channel, one of the more attractive features of the app (since RedZone gives you lots of live action, even on games that might otherwise be blacked or not viewable for other reasons). Verizon customers who are not More Everything customers must pay $5 a month for access to the NFL Mobile premium content.

Theoretically, you should be able to order RedZone from this "settings" page of the app. But it didn't work when we tried to click the button.

Theoretically, you should be able to order RedZone from this “settings” page of the app. But it didn’t work when we tried to click the button.

For many NFL Mobile customers, yours truly included, any live video at all was not available for long stretches of Sunday, and after a brief 2-minute “preview” period the RedZone content was also unavailable, and the app was not allowing it to be purchased. As of Monday afternoon, the MSR official testing lab still couldn’t get the RedZone box to work — clicking it kept taking us to a page explaining the charges but not offering a way to add it to our bill.

“NFL Mobile requires a number of backend systems to ensure only Verizon customers can get live NFL video,” said Riethmiller, in a prepared statement. “We experienced issues with one of the systems that validates customers, and it took longer than anticipated to resolve because of tremendous demand. We are confident we have addressed the issue going forward.”

Kristin Rooney, Verizon Wireless director of sponsorships and branded entertainment, would not comment on the NFL Mobile outages in a phone interview Monday morning. However, Rooney was happy to talk about the new features in NFL Mobile this season, including the ability to watch local games live, even if they are out of the traditional prime-time window NFL Mobile has access to. In addition to the local games, NFL Mobile premium customers are supposed to be able to watch live games on Sunday nights, Monday nights and Thursday nights, and also have access to RedZone broadcasts during the day. That is, when the servers are working.

BUY... MORE... SERVERS

BUY… MORE… SERVERS

Another unclear option is what happens to RedZone access when NFL Mobile customers visit NFL stadiums — while Verizon blocks access to RedZone at some stadiums, at others it allows it, usually through a partnership with a team’s stadium app. Rooney, however, did not have a list of stadiums where NFL Mobile customers could watch RedZone broadcasts during a game; most famously, the service was blocked at last year’s Super Bowl in MetLife Stadium.

Rooney also declined to say just how many customers Verizon has for its NFL Mobile app, though the Google Play store says the app has between 10 and 50 million installs. However, since a non-premium version of the app is available to customers with contracts from other carriers, it’s unclear how many “premium” members were overwhelming Verizon’s servers. It’s worth noting that Verizon is no stranger to large numbers of single-day activations, as its systems support more than 100 million wireless subscribers, nation-wide.

In a related note, NFL Mobile wasn’t the only streaming product having issues Sunday. According to a report at TVPredictions.com, the DirecTV streaming service for NFL games also suffered outages Sunday, also for the second straight year.

College DAS Update: AT&T and Verizon partner for DAS at Oregon; Minnesota taps AT&T for DAS at TCF Bank Stadium

Talk about an unlikely partnership: AT&T and Verizon Wireless announced that they have co-installed a DAS (distributed antenna system) deployment at the University of Oregon’s Autzen Stadium, a 200-antenna upgrade that should make cellular access a lot better for Ducks fans this football season.

There are few business competitions as balanced and as fierce as the one between the top two U.S. cellular carriers — so why are they doing the Kumbaya thing in Eugene? We haven’t heard any confirmation yet, but our guess is that it was somewhat of a forced partnership, due to an legacy deal between Oregon and Verizon, and the new Pac-12 infrastructure deal AT&T forged last year. (If either carrier would like to call in to confirm or deny, our lines are open.)

If you’re a follower of telecom business you might want to bookmark the Oregon press release announcing the deal and deployment, since it may be the first and last time you see Verizon and AT&T together in a single press release (that isn’t about keeping the government out of telecom regulation, that is). You can read between the lines when you see that AT&T is quoted first in the press release, Verizon second. Good news is, Ducks fans will have better cellular no matter which of the two major carriers they are a customer of.

We haven’t heard yet from AT&T about whether or not the conference is fully covered with DAS yet — according to this news report from last year there were only four Pac-12 schools whose DAS wasn’t up to snuff, with Autzen clearly being one of them. We are trying to get AT&T and Pac-12 folks on the line for a general update, so stay tuned.

AT&T bringing DAS to Minnesota’s TCF Bank Stadium

Moving to the other side of the Rose Bowl rivalry, AT&T announced it had installed a DAS at the University of Minnesota’s TCF Bank Stadium, a network of 339 antennas that will also be used by Minnesota Vikings fans since the NFL team is also playing there this year and next while their new stadium gets built.

According to AT&T, fans at TCF Bank Stadium used 106 GB of data on the new network during the Gophers’ Aug. 28 home opener against Eastern Illinois.

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.
