Stadium Tech Report: DAS, Wi-Fi puts end to no-signal problem at Denver’s Sports Authority Field

PeytonThese days, Denver’s Sports Authority Field at Mile High is the new home of the NFL’s most prolific signal-caller. With a record season for passing yards and passing touchdowns, Broncos quarterback Peyton Manning is recognizable for his animated pointing, shouting and line-of-scrimmage audibles, the ultimate practicioner of last-second communication.

Not too long ago, the fans at Mile High might have had to resort to the same tactics to communicate, using hand waving or shouting, since getting a cell signal was next to impossible. “Forget making a phone call, you couldn’t even send a text,” said Rick Seifert, communications manager for the Broncos’ stadium management company. “And it wasn’t just the fans. We [the staff] couldn’t make calls in the stadium to do our jobs.”

But in 2012, the Broncos changed all that with the installation of a full-featured distributed antenna system (DAS) deployed by TE Connectivity, and a fan-facing Wi-Fi network installed by Verizon Wireless.

The Broncos also put in a huge new digital scoreboard and robust back-end connectivity provided by Comcast as part of their blitz of networking improvements, and this past fall, AT&T joined in by upgrading its connection to the stadium’s DAS. By next year the Broncos hope to add AT&T and Sprint to its roster of Wi-Fi service providers, reflecting what vice president of information technology Russ Trainor sees as a “never ending growth” of wireless in-stadium consumption.

All carriers on board, slowly

One of the biggest problems with DAS deployments in stadiums is convincing major cellular carriers to work together. Since each carrier wants to deploy systems to do the best job for its customers, there is often a difference in opinion on strategy and operations, which is often followed by similar snags in contract negotiations. Trainor said that the stadium, built in 2001, presented unique RF challenges to wireless with its primarily exposed-steel construction. Verizon and Sprint were the first carriers to sign up for the neutral DAS, followed by AT&T this fall.

“It was tough to get them [all the major carriers] to agree on DAS, but we have good engineers on the back end and we came up with a nice solution for everybody,” said Trainor. While the antennas and stadium network are neutral, each carrier provides its own back-end gear, much of which at Mile High had to be placed in a building built outside the facility specifically to house telecom gear. In many stadium DAS deployments, the telecom gear can take up thousands of square feet, which can be challenging to find in facilities built before such needs were known.

“There’s no room inside for all the space they [the carriers] wanted,” Seifert said.

The Wi-Fi network, deployed by Verizon, uses Cisco equipment and is also a neutral host infrastructure, meaning that other carriers could use it to provide Wi-Fi connectivity to their clients if they so choose. According to Seifert, AT&T and Sprint will offer Wi-Fi services to customers next season, in part to answer the consistently growing demand. Like in other stadiums, fans at Sports Authority Field know what to do when they finally find bandwidth: Use more.

Steady growth in wireless use

When Sports Authority Field is at its listed capacity of 76,125 on game days, it becomes the 14th-largest city in Colorado, Trainor said. The team has already seen 525,000 downloads of its mobile application, which provides such in-stadium features as four different video replay angles, a connection to the NFL Network’s RedZone channel, and a direct link to the radio feed from hometown sports station KOA. The application is geo-fenced to ensure that the video rights are only used inside the stadium, and to give fans there a unique game-day experience.

According to Trainor, the team usually sees an average of 4,000 simultaneous connections on the Verizon Wi-Fi network on game days, though on colder days when fans need to wear gloves that number can drop in half. Trainor said the Cisco infrastructure is designed to accomodate 25,000 concurrent connections, a number the team hasn’t yet reached. However, the team did have to double the back-end capacity already for the Wi-Fi network, which is being used more as more fans find it.

“Word of mouth really gets [usage] going,” said Trainor, who noted that at a Kenny Chesney concert last year, the stadium crew saw data uploads outpace data downloads for the first time — a sure sign that fans in attendance were using the network to do things like share pictures and videos with their social-network connections.

“We haven’t seen any true bottlenecks yet, but usage is consistently rising, game after game, for concerts, soccer and football,” Trainor said.

A good sign from the Wi-Fi networking statistics is a shift in usage from the often crowded 2.4 GHz bands to the 5 GHz bands, which Trainor said is likely due to fans using the latest 5 series iPhones, which support the 5 GHz Wi-Fi frequency. And no matter what happens to the Broncos in the playoffs, Trainor and Seifert know what they will be doing this summer: Upgrading the network components, in the never-ending battle to provide bandwidth.

“Verizon and Sprint have already made significant upgrades to their DAS deployments because of demand and changes in technology, like LTE,” said Seifert. “And next year we’ll probably see AT&T circle back again. It’s very dynamic.”

“As smart phones get smarter it’s a never-ending challenge” to provide connectivity, Trainor said. “It’s a job that’s never finished.”

Stadium Tech Report: Boingo, AT&T answer call for more DAS bandwidth at Chicago’s Soldier Field

Soldier FieldWhether or not the Chicago Bears will beat the Green Bay Packers this Sunday is a question still answerable only by higher deities. But if those powers that be decide to unleash weather conditions of biblical proportions again, at the very least the Soldier Field folks can be confident that their in-stadium network will stand up to the challenge.

Earlier this year, tornado weather hit Soldier Field and caused an unusual 2-hour delay during the Nov. 17 Bears-Ravens game. While the deluge was too dangerous for football, for Doug Lodder and Luca Serra, it was a big test to see if the stadium wireless network upgrades they’d recently helped install could stand up to a huge, unexpected traffic surge.

“We thought we’d probably see some good [network] usage with the weather delay and tornados,” said Lodder, vice president of business development at Boingo Wireless, which recently concluded a big network upgrade at the home of the NFL’s Chicago Bears.

“We saw double the usual traffic from both AT&T and Verizon customers during the 2-hour delay,” said Serra, director of sponsorship and media for SMG, the outside entity that manages Soldier Field for its owners, the Chicago Park District. “During that break, we didn’t hear a single complaint [about the wireless network] from the media or the fans. It was a great test — not a desired one in any way, shape or form, but a great test.”

Upgrades needed at ‘oldest’ big stadium Wi-Fi network

Even though you can’t really plan or design for surges that might happen during extreme situations, Serra and Lodder and others running the Soldier Field network knew last year that an overall upgrade was needed. Home of one of the earliest (if not the first) big-stadium DAS and Wi-Fi networks, Soldier Field was showing 80 percent year-over-year traffic growth on the Wi-Fi network, Lodder said in a recent joint phone interview with Serra.

Along with DAS partner AT&T, SMG and Boingo spent last year adding more DAS capacity so that Solider Field now has 250 DAS antennas to go along an undisclosed number of new Wi-Fi APs. Though AT&T did some specific upgrades to its DAS presence at Soldier Field (including adding support for its new 4G LTE network), all the major wireless carriers are represented in the DAS via the neutral hosting of Boingo.

Why did the firms decide Soldier Field needed an upgrade? While Lodder said its DAS, which first started operating in 2011, was “pretty cutting edge at the time,” during the past couple years, data usage at Soldier Field has skyrocketed.

“Everyone has a device, and there’s a lot more social engagement and sharing,” Lodder said. “We’ve seen a huge increase in data use.”

“With this large increase in use, we said ‘let’s address the issue’ and not let it get to a point where it’s a problem,” Serra said.

Both Serra’s and Lodder’s teams were familiar with the need to balance performance and aesthetics at the venerable stadium perched on the edge of Lake Michigan. Since the network was put in after Soldier Field’s extensive renovation was finished in 2003, special attention needed to be paid to placements of Wi-Fi and DAS antennas.

“It wasn’t just bolting APs on,” Serra said. “We had to be very protective of the aesthetics of the building.”

For Lodder, that sometimes means that the best placement isn’t always available.

“There’s always challenges with architecture at stadiums,” Lodder said. “In a perfect world, there might be a certain place you want to put an antenna. In the real world, you can almost always count on changing that 20 percent of the time.”

A bigger construction concern of late is where to put the extensive amount of back-end telco gear needed to support the DAS infrastructure and upgrades. “Carrier base stations need several thousand square feet of space, and those need to be rooms with connectivity and power,” Lodder said. At Solider Field, Serra said some unfinished space north of the stadium proper was converted into a DAS equipment room, since there wasn’t enough available space in the main building. Lodder said for the recent upgrade, additional power upgrades were installed as well.

Still, even with all the challenges the Boingo, AT&T and SMG teams were able to go from design to finished construction of the recent upgrade in 45 days this past summer, in part thanks to some interesting work schedules.

“After one preseason [football] game we had scaffolding going up at night, with three 24-hour shifts,” Lodder said. “It was a pretty accelerated build.”

There is no such thing as free Wi-Fi

One other interesting twist to the Boingo Wi-Fi network at Soldier Field is its cost — the company charges a $1.99 per day fee for Wi-Fi use, or you can purchase a regular Boingo monthly plan for $7.95 which will also provide access at Soldier Field.

While many if not most professional teams are making Wi-Fi services free to paying ticketholders, Serra and Lodder said that the Bears aren’t.

“The Bears are a tenant of the Park District, and no one [from the team] has ever said ‘we’re going to pay to turn it [Wi-Fi] on for free,’ ” Serra said. Lodder noted that in the end, someone somehow has to pay the cost of connectivity.

“Someone’s always got to pay for it — Wi-Fi isn’t free,” Lodder said. “Some teams may feel they’ve made enough on the tickets to offer [Wi-Fi] free, while in other cases users pay either with money or with eyeballs, by viewing some ads.”

While the NFL itself is still somewhat vague on its league-wide plans for in-stadium Wi-Fi — other than saying that teams should provide it — Serra and Lodder are confident that Soldier Field will be at the top of the chart when it comes to network performance.

“If and when they [the NFL] roll out standards for network performance, we’re going to exceed them,” Lodder said.

Stadium Tech Report: Wi-Fi ‘coaches’ help fans find network in New England and Philly

What good is a stadium Wi-Fi network if the fans don’t use it? To help avoid the obvious answer, the providers of wireless services in the New England Patriots’ Gillette Stadium and the Philadelphia Eagles’ Lincoln Financial Field are now supplying “Wi-Fi coaches,” roaming groups of helpers who help fans get connected to the in-stadium network. With assistance from the digital sidelines, fans at those two stadiums can now conquer what may be the biggest hurdle to in-stadium connectivity: Just figuring out how to make your device work.

In a phone interview with John Brams, director of hospitality and venues with Enterasys (the stadium networking company recently acquired by Extreme Networks), we asked about what problems the providers had experienced with their new networks at Gillette and the Linc. Perhaps not surprisingly, one of the biggest concerns wasn’t technical, but simply user confusion.

“After we installed the networks, we quietly realized that the [biggest] fundamental issues weren’t with the design — it was user issues,” Brams said. When you consider that the average age of a Patriots fan at the game is 51 or 52, Brams said, it’s understandable that many of them might not know how to do things like download an app or find a Wi-Fi connection for their phone. Communicating with fans at the games is also problematic, he said.

“You can’t just pick up the phone and call people, and you can’t really have a help desk at the stadium,” Brams said. What the Enterasys/Extreme folks hit on was a plan familiar to any NFL fan, who knows all about the long list of assistants for things like offensive line play and special teams: Give the fans their own Wi-Fi coaches.

Now at both Gillette and the Linc the Extreme folks have 16 or more Wi-Fi coaches roaming the stands and concourses during games, readily identifiable in team-color jackets that announce them as friendly types to help fans connect to Wi-Fi. According to Brams, it’s not just the fans who benefit from the outreach program — the teams and stadiums also get instant feedback from users, which can help them quickly pinpoint any network problems.

“From a team perspective, the coaches are a great way to interact with the fans,” Brams said. “You get immediate feedback and if there are any problems, you get the information from the fan and quickly close the loop.”

The personal show-me coaching works very well in a stadium situation, Brams said, because fans will quickly pass on successful tactics to those sitting nearby. “If one person learns how to do something, it spreads like a chain reaction,” Brams said. One problem the Extreme coaching team has been communicating to users was a known bug with the team app and Android platforms, which could be fixed with a simple download. The bottom line, Brams said, is to ensure a good network experience the first time out — otherwise, fans might never try to connect again.

“I ran into one fan at Gillette who said the network didn’t work — but the last time he tried it was 2 years ago,” Brams said. “You need to deliver the first time they use it.”

Steady increase in Wi-Fi usage

At both Gillette, where the network was installed last season, and at Lincoln Financial, which is in its first year of Wi-Fi, Extreme is seeing a steady increase in usage, Brams said. An interesting side note is that while numbers of users are rising steadily, the amount of data being consumed overall is growing more rapidly, suggesting that the fans who do connect are starting to do more.

On the coaching front, Extreme is looking into helping its team customers find ways to expand the program, perhaps with some device-charging stations staffed by more Wi-Fi coaches. The idea is also open to possibilities for branding and advertising on the coaches’ jackets as well as at the charging stations, Brams said, with the final options limited only by the stadium owner and operators’ imaginations.

The best part of the program is when a coach helps a fan connect to the Wi-Fi, which is often a game-changing experience in the world of stadium connectivity. “These places [stadiums] used to be such a connectivity black hole,” Brams said. “Now people are excited when they connect.”

Stadium Tech Report: Partners the key to fast Wi-Fi deployment at Staples Center

Staples centerDuring the 2012 NHL playoffs, no other team could stop the Los Angeles Kings. But as the Kings’ fans were celebrating their team’s run to the Stanley Cup, their cheers from Staples Center stayed inside the walls. Without a Wi-Fi network or good cellular connectivity in the venue, fans there were shut off from sharing their joy with the outside world — a frustration they let team officials know about, in no uncertain terms.

“Not having Wi-Fi was really impacting the fan experience, especially during that championship run,” said Denise Taylor, chief information officer for arena owner AEG. “Our fans went through a lot of pain. And we heard them.”

Fast-forward to the 2013 playoffs, and while the LA Kings weren’t as successful on the ice, at least the fans were able to stay fully connected while at the games thanks to a new HD Wi-Fi network and a neutral DAS deployment at Staples Center. With some impressive help from infrastructure partners Cisco and Verizon, AEG was able to get Wi-Fi and a full DAS deployment installed in both Staples and the adjoining LA Live center in just two and a half months, despite nearly constant activity in the venue that never sleeps.

With its network now in place, AEG and Staples are keeping all the Los Angeles teams’ fans connected while busily looking for more opportunities to not only further enrich the fan experience, but to also add to the teams’ and facilities’ bottom lines. And AEG is already learning lessons about how to better deploy Wi-Fi at its arenas and venues worldwide, including the knowledge that fan network use is showing no signs of slowing down.

Building a network in a building that never sleeps

According to Taylor, deciding that Staples Center needed a Wi-Fi network was the easy part “It was a must-have,” she said. “We knew had to get it in immediately.”

The hard part? Building that network into a building that hosts not one but two NBA teams, the Los Angeles Lakers and the Los Angeles Clippers, as well as the NHL’s Los Angeles Kings and the WNBA’s Los Angeles Sparks, plus is host to numerous concerts special events and the Grammy Awards. When the business plan was put in place in late 2012 to deploy the networks, Taylor said there were only four “dark” nights during the two and a half months of construction.

“That’s when it pays to have really great partners,” she said. Though there was heavy lifting necessary to retrofit the 20,000-seat venue, including opening up walls to install conduit and access points, Taylor said AEG’s partners worked around the busy Staples event schedule, with most work taking place between the hours of 2 a.m. and 2 p.m. When the dust settled, Cisco had installed a total of 463 APs in both Staples Center and L.A. Live, meaning that fans could stay connected inside the stadium and outside at the adjoining cluster of stores, restaurants, movie theaters and other facilities.

Almost instantly, fans were talking about events, sharing pictures and messages on social media networks. “It was a great feeling to see people talking about the games,” Taylor said. “Our partners really delivered.”

Future Advice: Don’t make any small network plans

LA Kings fans, who previously couldn’t even use the team’s app while at Staples, are now the biggest network users. According to Taylor, an average of 3,000 fans are connected to Wi-Fi during LA Kings games at Staples Center, just ahead of the facility’s average NBA game network user number of 2,410. Even at this early stage of the game, Taylor is seeing that her team’s predictions for network usage might have been low.

“We had originally designed [the network] for use by 25 to 30 percent of a capacity crowd,” Taylor said. But during a recent concert run of four sold-out shows by the band One Direction, Taylor said 35 percent of attendees were using the network during those shows.

“Use of mobile phones in venues is just going to grow and grow,” she predicted. “We’re seeing more and more penetration every day.”

And while pure connectivity is great, Taylor and AEG are now moving forward to enhance the fan experience in multiple ways, including implementation of mobile ticketing apps and apps for ordering food and concessions from your phone.

“We’re in the early stages, but all of that — concessions, ticketing, team apps — is in the works,” Taylor said. “Having a real HD Wi-Fi network creates so many business opportunities, for teams, venues and owner groups. There’s the whole area of captive analytics, which has tremendous potential upside. It’s just a question of how you monetize this big digital asset you have in your hands.”

More lessons: Don’t skimp on 2.4 GHz, and pick good partners

When it comes to Wi-Fi technology, the future is devices that work in the 5 GHz unlicensed spectrum band, which has tons of available bandwidth. Many newer devices, like Apple’s iPhone 5 series, include radios for connecting to 5 GHz Wi-Fi. But Taylor said venue owners and operators need to make sure they don’t skimp on building in support for the 2.4 GHz band, where a large legacy of devices still operate.

“Designers may prefer the 5 GHz range but if you only support that band the truth is you would eliminate a good portion of consumers,” Taylor said. “There are also back of house management applications that still require 2.4 GHz support. So you still have to build for the lowest common denominator of devices to make sure you are engaging every fan who comes in, even those with older phones.”

And since most networks built now are going to be put into arenas that already exist — meaning retrofits — there will probably be a Staples Center-like challenge of doing deployment work around events. That means, Taylor said, that owners and operators need to find partners who are “willing to work hours that aren’t always 8 to 5.”

As AEG develops overall plans for site operations at its numerous international locations, Taylor said that wireless networks are no longer seen as a luxury.

“The two most important things are having HD Wi-Fi and a robust DAS,” she said. “You give the fan what they want, and take advantage of all the opportunities to monetize the network. It’s just not an option anymore.”

Stadium Tech Report: Aruba’s Wi-Fi smarts at the base of Trail Blazers’ new stadium experience

An Aruba AP inside the Moda Center

An Aruba AP inside the Moda Center

Though it’s not been generally known for stadium deployments, being named as the Wi-Fi supplier for the new network at the Portland Trail Blazers’ 20,000-seat Moda Center should give a boost to the arena business for Aruba Networks, the Sunnyvale, Calif.-based network infrastructure supplier.

After learning of Aruba’s win in Portland we caught up via phone with Manav Khurana, vice president for product marketing at Aruba, to learn more about what Aruba is doing differently in the stadium market. Though the company might have had the inside track in Portland (since it had previously sold gear there for an internal Wi-Fi network) Khurana said the Blazers had treated this year’s stadium technology upgrade as a brand-new project. What helps set Aruba apart from other vendors, Khurana said, are some in-house hardware innovations combined with software management techniques that help overcome the obstacles faced by wireless LANs in crowded spaces.

Focused antennas, optimized connections

To help meet the Moda Center’s design criterium of supplying a wireless network “faster than your home,” Aruba brought in the custom antennas it has designed for use in high-density situations. The Aruba access point antennas, Khurana said, can be focused “like a floodlight,” allowing pinpoint coverage of specific seating areas — and also allowing multiple APs to be positioned closely together without fear of interfering with each other.

On the management side, Aruba has an interesting piece of AP firmware it calls ClientMatch, which Khurana said helps combat the problem of mobile devices “locking on” to a specific access point, even if it’s not the best AP the device might see. “ClientMatch actively monitors all APs [in a network] and if there is a better AP available [for a device] it will move the connection in a real-time basis,” Khurana said. Aruba also uses some internal firewall smarts to help prioritize traffic, a necessary evil especially when video streams are part of the equation, as they are with the new Trail Blazers’ team app.

Advertising and infrastructure partners team up in Portland

One aspect that is unique from a business angle in Portland is the branding of the public Wi-Fi network by the local Toyota dealers, a longtime Blazers advertising partner; in fact, the in-stadium SSID reveals the name “Toyota Free Wi-Fi.” Since Wi-Fi users everywhere are accustomed to seeing a splash screen when they sign in to a new network, Khurana said it should get easier to convince advertisers that Wi-Fi connectivity can provide a new kind of billboard, one with the opportunity for one-on-one engagement.

“Three or 4 years ago it used to be tough [to sell Wi-Fi ads],” Khurana said. “Now everyone sees that screen whenever they log in at the airport. It’s a lot easier now to talk about those kinds of [advertising] opportunities.”

The new network infrastructure in Portland — which will eventually include 400 Aruba APs — was deployed by Crown Castle, and a new team app for this NBA season was developed by YinzCam, which has numerous big-league team app deals in all the U.S. major leagues. Thanks to good local coverage by the Oregonian, we should be able to follow the network’s performance over the NBA season (and see if the locals ever get around to calling the stadium by the new sponsor name instead of the Rose Garden handle by which it has been previously known).

Stadium Tech Report: Cal Bears, AT&T get creative with DAS deployment for Memorial Stadium

Cal's Memorial Stadium. Note the lack of overhanging structure.

Cal’s Memorial Stadium. Note the lack of overhanging structure.

What do you do when the construction of your big bowl stadium won’t allow you to install Wi-Fi? You start building the biggest DAS you can, to bring as much cellular capacity as possible to the fans who will fill the seats.

That problem and solution is now underway in Berkeley, at the University of California’s newly renovated Memorial Stadium. Though it now has a shiny new press box and suites on its west side, the 63,000-seat facility still has its old “big bowl” shape throughout the rest of the facility, an architectural quirk that leaves no place to put Wi-Fi antennas. To try and best overcome the design challenges, Cal and its partner AT&T are currently putting in place as big a DAS (distributed antenna system) as they possibly can, to bring as much cellular capacity as the stadium placements will allow.

At a press event Thursday to officially announce AT&T’s campus-wide Wi-Fi and DAS deployments — which are currently bringing welcome speedy connectivity to all the other parts of the school’s Berkeley footprint — Cal officials and AT&T execs noted that bringing better wireless to Memorial Stadium is also going to be a necessary evil, going forward.

“We compete with the couch, and the HD TV,” said Solly Fulp, the Deputy Director of Athletics and Chief Operating Officer at Cal, at a quick press conference kicking off the Thursday events. “If we do not deliver an outstanding fan experience, people will do other things with their time.”

Right now, the wireless experience inside Memorial isn’t cutting edge. Basically a big concrete bowl filled with seats, Memorial has none of the overhanging levels that allow you to more easily attach antennas underneath, be they Wi-Fi access points or the small antennas used in DAS deployments. While the new press box and suites and internal construction improvements completed last year have brought the facility up to date on one level, for supplemental wireless coverage right now AT&T is using COWs (cell towers on wheels) in several spots around the stadium, covered with stealthy black cloth. But construction for a big, new DAS deployment is already underway.

According to AT&T, the low poles sticking up from the top of the bowl, currently used to house speakers, will by next season be equipped with DAS antennas focused down into the sections of seats. There will also be DAS antennas housed inside boxes mounted above tunnel entrances, and along the underside of the press/suite facility wherever possible. While Wi-Fi can typically support faster communications and more bandwidth, the DAS AT&T is putting in will support AT&T’s 4G LTE network, which is as fast as cellular gets. As in most stadiums we’ve talked to, putting in a DAS is priority one for wireless, since it helps eliminate the “no signal” problem common to big facilities that don’t have any extra cellular or Wi-Fi services.

AT&T, which will act as a neutral host for the Memorial DAS (meaning that other service providers can connect their back-end systems to the AT&T-installed antennas) is even getting creative finding space for its head-end gear, the routers and switches needed on site to help complete the cellular connections. In one concourse underneath the stands, AT&T and Cal are walling off a small part of the internal walkways to house the necessary DAS gear.

From there, optical fiber will connect the stadium to a nearby AT&T central office, where more call processing can take place.

Will the big DAS be enough to keep Cal fans connected? From what we heard at Thursday’s press event both the school and the carrier think that the wireless networks will always be a work in progress. And according to Cal’s Fulp, better cellular is already one of the top three concerns voiced by season ticket holders.

“It’s the simple things that matter,” Fulp said, saying that for the most part, fans at games want to be able to contact people at home — “sending a text to the babysitter, saying you’ll be late” — or to share a picture or a video with friends who couldn’t be at the game. “People expect to be connected, and at sports events it’s amplified,” Fulp said.

When the members of Cal’s class of 2014 toss their graduation caps into the air next spring, Fulp wants to see a “best in class” DAS in action at Memorial. What will that take from partner AT&T? “Every place we can find to put an antenna, we will,” said one AT&Ter who showed us around Memorial. Sounds creative to us.
