I needed a one of the NiNerds Sunday at Levi’s Stadium, and thanks to a new wardrobe addition, they were a lot easier to find.

Discovering a problem with the Levi’s Stadium app, I looked around for one of the stadium’s walk-around technology helpers — aka the “NiNerds” — and found one quickly thanks to the new neon-yellow vests many were wearing during Sunday’s game between the San Francisco 49ers and Washington.

Earlier this season, the NiNerds were much more nattily dressed in their gingham-check shirts, bow ties and fake horn-rim glasses. While cool and cute, the outfits proved hard to recognize in the crowd, especially since the NiNerds’ red check shirts looked a lot like the jerseys and t-shirts worn by the many faithful fans. Perhaps in order to make the NiNerds stand out more, the team dressed them in neon Sunday, like Wi-Fi “coaches” in other stadiums have done.

Unfortunately, the NiNerd I talked to wasn’t able to solve my problem (it seems to be related to a known bug in the newest Android release of the stadium app) but I did notice during my visit Sunday that the NiNerds in general seemed to be more numerous and visible, and they even got a nice shout-out on the Levi’s Stadium big screen (see photos below). Below are some thoughts and observations on the network performance, the app performance and the overall fan experience at Levi’s, which I hadn’t visited since the season opener back on Sept. 14.

Wi-Fi network struggles at 2.4 GHz, soars at 5 GHz

On the network-performance side of things, the Wi-Fi system seemed as robust as ever for new devices, including the AT&T LG Optimus G Pro I’ve been test-driving lately. With the Android device and its 5 GHz Wi-Fi connection I hit speeds of 31 Mbps download and 29 upload before the game on the Levi’s Stadium outside concourse, and then had a 14 Mbps download connection in my seat in section 229 (south end zone) at kickoff. In the third quarter I wandered up to the top (7th) level of seats, and got a 28/33 Mbps reading while waiting in a concession-stand line.

With my older Verizon Droid 4 device, however, I struggled to connect to the Wi-Fi network. Since the phone only runs on the 2.4 GHz Wi-Fi frequency, it doesn’t do well at Levi’s Stadium, where the Wi-Fi is more heavily tuned for newer, 5 GHz-capable devices.

The best Wi-Fi speedtest I could get with the Droid device was a 1.06 Mbps download/3.04 Mbps upload mark, from the same spot on the outer concourse where the newer device recorded blazing connectivity speeds. Switching it over to its Verizon 4G LTE radio, I was able to get much faster connectivity, including one mark of 21.60/9.58 on the main level inside concourse.

I also ran out of juice on the Verizon phone before the end of the game — which could have been either the device draining due to its inability to get a solid connection, or due to the fact that it’s getting old and the battery doesn’t hold a charge that well anymore. Judging from the crowds around the Levi’s Stadium recharging stations (the picture to the left was taken during pregame) I am not alone in my device-energy woes.

App problem derails beacon test

One of the main tasks I had planned for Sunday was to see how well the beacon-assisted wayfinding feature in the stadium app worked. Only problem was, in the new update of the Levi’s Stadium app that was released in the past week (which I downloaded to both devices Sunday morning), several features were missing, including the “Maps” feature.

A NiNerd I talked to outside the stadium on the Faithful Mile area showed me the maps/wayfinding feature on his iPhone, and pulled up a GPS-supported direction message that pointed the correct way for me to enter the stadium. But neither he nor the NiNerd I talked to inside the stadium could figure out why both of my Android devices weren’t showing the maps feature, or several other features on the left-upper-corner pull-down menu.

According to Louise Callagy, vice president of marketing for app developer VenueNext, the new version of the app released this week did have a known Android bug. In an email response Sunday night Callagy said, “we know we have a bug where Android gets confused and won’t return results from the network,” adding that rebooting the device might have fixed the problem; however, I did reboot both devices during the game and the problems were not corrected.

Callagy said the Levi’s network also had issues Sunday in getting location information from the beacons. “Our plan is to re-write the code [for the app] and solve this issue, releasing a new version before the Seahawks game on Thursday,” Callagy added in her email.

On the good-news side the replay function of the Levi’s Stadium app was more impressive than earlier versions, with highlights appearing in the app in mere seconds after the original play had concluded. After the Niners’ first TD pass of the day, I was able to view the highlight of the Colin Kaepernick-to-Anquan Boldin pass just after the extra point had been kicked.

I was also able to see the red light/green light system for restroom wait times that drew so much attention when it was talked about earlier this year. However, in real-life practice it’s doubtful anyone thinks of looking at the app when it’s time to go. (It’s also quite likely that while you are looking at the app for a short restroom line, a natural break in action will occur and restroom lines will predictably lengthen everywhere.) I found a quick trick for Levi’s attendees that might pay off in the future: If the restroom you’re aiming toward has a long line, walk a small bit farther to find its back door — where there is often no line at all.

I messed up later in the game, however, in thinking that it would just be easier to find a concession stand than to use the app’s express window ordering function. At least the 10 minutes I spent in line behind three women who were apparently ordering for their entire row (five hotdogs, six orders of fries, two orders of wings, two beers and one large ice water) gave me time to conduct a couple more Wi-Fi speedtests. Next time, I’m using the food-ordering features on the app.

I also made great use of the app’s ability to let fans watch live game action (I chose the feed from the main video screens in the stadium). Since I had to leave early I was on the first VTA train when I saw the game-winning TD run courtesy of the app’s live action broadcast. The live video, incidentally, kept playing seamlessly over the AT&T 4G LTE network as I sped away from the stadium, allowing me to watch the final game-sealing sack as I beat most of the traffic home.

VTA trains a smooth ride, once you figure out how to get on

I also had another smooth ride to and from the stadium using the VTA light rail trains from Mountain View — once I was on the train it took just a little over 30 stress-free minutes both coming and going. Getting on the trains, however, is a process that could still use some work. The Mountain View station, which is logistically hampered by having to share space with the Caltrain tracks and station, has very little signage on game day, and has a lot of confusing temporary gates to try to flow foot traffic toward the ticket-verification checkers.

Once I figured out the maze and was guided across the Caltrain tracks I was directed to one of two waiting trains — but then a VTA staffer looked into the train and told people there were also express buses that wouldn’t stop on the way to Levi’s (unlike the trains, which stop at numerous stations en route). The quizzical advice — nobody said if it was any faster to take the buses — had many people wondering what they were supposed to do, causing a delay in closing the train doors as people made up their minds without any more information.

Once we arrived at the stadium, on the exit platform there was no person or sign directing fans in the proper direction. Good thing for the many newbies on the train (the train 2 hours before kickoff was packed) several of us were veterans and directed everyone down the proper ramp. For the return trip the Mountain View line suffered from similar lack of information and signing — and after one train passed the station with signs that said “Not in Service” we got on a second train that also said “Not in service” but whose doors opened anyway and one person in a yellow vest told everyone, “get inside.”

Overall impressions: Levi’s experience and technology still a work in progress

While I continue to be impressed by the network and app performance at Levi’s Stadium, I also felt several times on Sunday like the technology, the stadium and the entire fan experience is still a work in progress — perhaps something to be expected for a venue in its first year of events. But I have to wonder a bit about releasing a new version of the app in midseason, without apparently testing it enough to make sure it worked well on all devices that might want to use it.

I’m also still skeptical on how well the wayfinding feature will work in real world situations; though it sounds great to be able to get GPS-like directions to places inside the stadium, the reality of trying to walk around looking down at your phone on one of Levi’s Stadium crowded concourses is more likely to lead you into someone’s backside. Anyone with tales to tell of Levi’s Stadium technology experiences, please chime in below in the comments or send me an email to kaps at mobilesportsreport.com. I’d be especially interested to know if anyone else saw my app problems Sunday on Android phones. More Levi’s pictures below.

NFL’s CIO says teams need to share technology know-how

Michelle McKenna-Doyle, CIO, NFL

Michelle McKenna-Doyle, CIO, NFL

Editor’s note: the following interview with NFL CIO Michelle McKenna-Doyle was featured in our most recent long-form report, THE FOOTBALL ISSUE, which is available for free download. In addition to team-by-team capsules of technology deployments for all 32 NFL teams the issue also has several in-depth stadium technology profiles and an extensive look at the technology behind the San Francisco 49ers’ new Levi’s Stadium. Get your copy today!

In a league known for its intense rivalries, is it possible to get teams to work together and share information for the betterment of all? In the area of stadium technology, that task is on the to-do list for Michelle McKenna-Doyle, who is now in her third season as chief information officer for the National Football League.

In an interview with Mobile Sports Report, McKenna-Doyle outlined some of the league’s recent accomplishments in technology-related areas like instant replay and digital content, while also explaining how the league oversees stadium technology deployments. According to McKenna-Doyle, one of her office’s jobs is to act as a best-practices and lessons-learned clearinghouse, to better move the state of NFL stadium technology forward faster as a whole.

“One of our roles is helping teams help themselves” with technology deployment strategies, McKenna-Doyle said. “What we want is to provide a forum where clubs can share information with each other. If somebody’s done something and learned it doesn’t work, we can tell other clubs not to waste their time doing the same thing.”

The business use of technology

Focusing on the business uses of technology and not the 1s and 0s is somewhat of a natural fit for McKenna-Doyle, who spent 13 years at the Walt Disney Company in disciplines including finance and marketing before becoming a VP in IT for two years. During CIO stints at Centex Homes and Universal Orlando Resort, McKenna-Doyle said she focused on using technology to enhance the guest experience, a goal the NFL sought when it brought her aboard in September 2012.

“Part of my job is making sure our in-stadium experience for mobility meets the needs of our fans,” McKenna-Doyle said. While it is true that commissioner Roger Goodell said he wanted all NFL stadiums to have fan-facing Wi-Fi, and that the league does expect teams to meet a minimum set of connectivity standards, McKenna-Doyle said the NFL’s overall stadium-tech strategy is to be more of a guide than to dictate exactly which technologies or apps teams should deploy.

“People really are fans of their own team first, and we encourage clubs to have that engagement, and help them interact with fans,” McKenna-Doyle said. “There are minimum standards and we do grade their [technology] experience, and report that back to the club. But they manage it. We are more of a guide.”

Putting out a plan for stadium Wi-Fi

In the area of Wi-Fi, for example, McKenna-Doyle said that last year the league put together “a really deep-dive spec” that laid out all the basics necessary for stadium Wi-Fi deployments. “That was so teams didn’t have to start at square one for design,” McKenna-Doyle said.

The league also helped move Wi-Fi deployments forward faster by signing a preferred-supplier deal with Extreme Networks, under which teams get a discount on pricing in exchange for the league-wide sponsorship exposure. (Editor’s note: This week, the league announced that Extreme is now the official Wi-Fi technology supplier for the NFL.) Though teams are not required to use Extreme’s Wi-Fi gear, new Extreme-based Wi-Fi networks are in use this season at Seattle, Jacksonville, Tennessee, and Cincinnati, joining two previous Extreme installations in Philadelphia and New England.

“It’s a great option if teams choose Extreme, and it [the league deal] also creates a competitive environment for other suppliers like Cisco to step up,” McKenna-Doyle said.

If necessary, the league can also play Wi-Fi matchmaker, as McKenna-Doyle said it did in bringing partner Verizon into Seattle, where the carrier deployed a Wi-Fi network at CenturyLink Field that is live this season.

At the writing of this report, 10 of the NFL’s 32 teams still had no fan-facing Wi-Fi services at their stadiums, a list that includes Green Bay, Baltimore, Cleveland, Buffalo, Houston, Oakland, San Diego, Washington, Minnesota and St. Louis. While McKenna-Doyle said that there are “a few more Wi-Fi announcements coming,” she also noted that some teams with lease uncertanties still don’t have firm plans to deploy Wi-Fi.

Help on the app side with partner YinzCam

McKenna-Doyle said the league also provides assistance in stadium application development via YinzCam Inc., a Pittsburgh-based company that has developed mobile apps for a number of pro sports teams. The NFL, which was an investor in YinzCam, uses the company’s technology in its league mobile apps, and McKenna-Doyle said YinzCam is also developing an app for the upcoming Super Bowl XLIX that will be “like nothing we’ve ever had before.”

Though teams are not required to use YinzCam – the San Francisco 49ers, for example, turned to newcomer VenueNext to develop their Levi’s Stadium app – McKenna-Doyle said that YinzCam may be a fit for other teams.

“For quality and speed to market, [YinzCam’s] product is very strong,” McKenna-Doyle said.

It’s about the fans, not the technology

Following a summer that saw her office overseeing the new method for on-field official review of replay calls – “which meant building a new system for 32 teams, 31 stadiums, and training all the officials” – as well as the launch of the NFL Now digital content site, McKenna-Doyle is back spending time with teams, counseling them on technology deployment resource management – “what to prioritize, and what to put on the back burner,” she said.

That includes technology ideas that might not work operationally, like a food-ordering service that isn’t staffed properly. For the in-seat food ordering feature at Levi’s Stadium, for instance, the 49ers said they did extensive research, hiring and training to make sure they had enough feet on the ground – runners carrying orders – to make the tech-inspired feature work.

If teams don’t do the human engineering behind the scenes, McKenna-Doyle said, the technology may not be that cool.

“We stress that it’s not about the technology, but about the fan experience,” McKenna-Doyle said. “It has to be operationally sound, and it has to be integrated with being at the game. If it’s not something that’s operationally sound, you might be better off not doing it.”

There is a buzz around Levi’s Stadium entering this season. And for good reason. The brand-new venue boasts more than 1,200 Wi-Fi access points and 700 DAS antennas. Aruba Networks (Wi-Fi) and DAS Group Professionals are hoping to fulfill the 49ers’ desires to own the most-connected stadium in all of sports. An ambitious new team app, with replays and food ordering and delivery to all seats is also part of the technology offerings.

Early tests of the stadium network during the preseason and regular season opener were promising, with Wi-Fi performance at Super Bowl-surpassing levels. On the DAS side, strong cellular signals were reached, with a nearly full house of fans. The question for the network, like the team itself – can it keep performing at a high level during the full season?

Seattle Seahawks
CenturyLink Field
Seating Capacity: 72,000
Wi-Fi-Yes
DAS-Yes
Beaconing – No

Fans of the reigning Super Bowl Champions will have more to cheer for in coming years at CenturyLink Field. The question is, will the loudest stadium in the NFL stay that way if Seahawks fans are using their phones more often, now that Verizon has installed stadium-wide Wi-Fi using Extreme Networks equipment?

St. Louis Rams
Edward Jones Dome
Seating Capacity: 66,000
Wi-Fi – No
DAS-Yes
Beaconing – No

After a proposed $700 million dollar upgrade was rejected, the St. Louis Rams are still seeking to improve the Edward Jones Dome. The good news for fans is that for this season a Mobilitie neutral-host DAS should significantly improve cellular communications not just in the stadium itself, but also in the adjacent convention center.

Everything is bigger in Texas – including connectivity. AT&T Stadium features 1,525 Wi-Fi access points and 1,374 DAS antennas. That’s enough cellular capacity to service the small suburb of McKinney, Texas. While watching Tony Romo target Dez Bryant, Cowboys fans will notice a new 130-foot LED display along the east platform. The AT&T Fan Experience board features 40 robotic panels that work in combination with other stadium displays to entertain fans all game along. And don’t forget the big TV hanging in the middle of the place!

New York Giants
MetLife Stadium
Seating Capacity: 82,500
Wi-Fi – Yes, 850 access points
DAS – Yes, over 600 antennas
Beaconing – No

The Super Bowl champions just three years ago, it appears their bunk mates’ play is rubbing off on the Giants. Like the cross-town Jets, the G-Men missed the playoffs for the second straight season last year. If it’s any consolation, the Giants still share one sports top venues in MetLife Stadium. AT&T and Verizon gave enough love and attention the stadium last year as host of Super Bowl XLVII. Over 600 DAS antennas, 850 Wi-Fi access points, Cisco StadiumVision with over 2,100 HD TVs around the concourse – that’s a recipe for a good time at a game, at least from a connectivity standpoint.

Philadelphia Eagles
Lincoln Financial Field
Seating Capacity: 69,176
Wi-Fi – Yes, 600+ access points
DAS-Yes
Beaconing – No

Lincoln Financial Field is one of the “greenest” stadiums in all of professional sports. And that’s not just because of the Eagles’ colors. All (100 percent) of the Eagles operations are powered by the sun and the wind. The stadium’s connectivity is something fans can get behind too. With over 600 Wi-Fi access points and a group of Extreme Networks’ “Wi-Fi coaches”, the Eagles are doing everything they can to make sure fans are connected at games.

Washington Redskins
FedEx Field
Seating Capacity: 85,000
Wi-Fi – Limited / club level only
DAS-Yes
Beaconing – No

A new coach, name controversy, and a $27 million dollar renovation underway at FedEx Field. It’s been an offseason full of distractions in the nation’s capital. The good news: The team just signed a deal with supplier Huawei to put Wi-Fi in the stadium, first in the club seats and then (hopefully) next year in the full seating bowl.

FedEx Field gets suite-level Wi-Fi from Huawei

FedEx Field, home of the NFL’s Washington, D.C. franchise, is getting Wi-Fi service in its 330 suites from Chinese telecommunications gear provider Huawei, according to an announcement from the team and the company.

Rob Verkon, senior solution sales and marketing manager for Huawei Enterprise USA, said in a recent phone interview that the Wi-Fi network is currently being installed with a goal of making it available “for the final games [of the season] in December.” Washington hosts the St. Louis Rams on Dec. 7, and then has two more scheduled December regular-season home games, Dec. 20 vs. the Philadelphia Eagles and Dec. 28 against the Dallas Cowboys.

The deal is the first major stadium Wi-Fi win in the U.S. for Huawei, which claims to also have “networking and infrastructure” deployments in major stadiums in Europe. A major competitor to large U.S. networking firms like Cisco, Huawei has been at the center of controversy in recent years, including being tabbed as a security threat by U.S. government officials, and later as a reported target for N.S.A. surveillance.

According to the press release, Huawei has entered into a multi-year sponsorship deal as the “official technology partner” for the Washington team. Though Verkon would not reveal the specifics of the network deployment costs, he did confirm that the company will receive some payment in the form of advertising, signage and other sponsorship identification.

Verkon said Huawei will be deploying 170 802.11ac access points to cover the 330 suites in the 85,000-seat FedEx Field. Though there is no mention of further deployment arrangements in the press release, Verkon said that “the eventual project” will include bringing Wi-Fi to the full seating bowl for next season.

Currently, the Wi-Fi situation at FedEx is a bit of a black hole; according to Verkon there is some existing Wi-Fi service in the stadium, and the team’s home page even lists Wi-Fi in its stadium guide (with the message “Fans in the seating bowl may access the free wireless network. Please see signs around the stadium for for login information.”). But in our research for NFL Wi-Fi services for our most recent Stadium Tech Report, MSR could not confirm that Wi-Fi services were available for the entire seating area.

Denver Broncos
Sports Authority Field at Mile High
Seating Capacity: 76,125
Wi-Fi-Yes
DAS-Yes
Beaconing – No

When Sports Authority Field at Mile High is at full capacity (76,125) on game days, the stadium is the 14th largest city in Colorado. And it’s a well-connected one too. Because the Denver Broncos deliver TE Connectivity DAS and a Verizon-built Wi-Fi network to the stadium. On the Wi-Fi side, Sprint should be joining this season, allowing its customers to join Verizon’s with free Wi-Fi access. Verizon, which has added Wi-Fi APs in strategic spots around the facility, has also added an additional 180 DAS antennas to its network. AT&T customers use a separate DAS at Sports Authority, and Sprint is also adding to its DAS deployment with more antennas.

Kansas City Chiefs
Arrowhead Stadium
Seating Capacity: 76,416
Wi-Fi – Yes, 600+ access points
DAS-Yes
Beaconing – No

On a quest to challenge the HD experience at home, Chiefs president Mark Donovan delivered Wi-Fi and a mobile app to Arrowhead Stadium last season. Chiefs fans will continue to be able to share status updates and check fantasy lineups on game days in 2014. Let’s see if the support helps Kansas City make the playoffs for consecutive seasons for the first time since 1994-1995.

Oakland Raiders
O.Co Coliseum
Seating Capacity: 56,057
Wi-Fi – No
DAS-Yes
Beaconing – No

The Raiders enter 2014 seeking their first winning season in over a decade. The fans will have to cheer their team on without Wi-Fi for another year at O.Co Coliseum. Despite being available for A’s fans, when the stadium capacity increases by almost 20,000 people for football, Raiders faithful are left without any access.

San Diego Chargers
Qualcomm Stadium
Seating Capacity: 70,561
Wi-Fi – No
DAS-Yes
Beaconing – No

The stadium that’s named after the wireless giant remains a mystery. Because Wi-Fi in Qualcomm Stadium, a facility whose sponsor’s fortunes come mainly from the sale of wireless-phone silicon, is still absent. The stadium that hosted the Super Bowl over a decade ago does have DAS antennas courtesy of AT&T for improved cell coverage.
