How do you bring new technology into a building and institution that embraces history as an integral part of its brand? There may be many answers but in the sports stadium world, Notre Dame’s renovation of its hallowed football field and the addition of high-speed Wi-Fi look like a good example for any other venues trying to solve the same issues.

At this past Sunday’s “New and Gold” game, a sort of glorified scrimmage, the public (including Mobile Sports Report) got its first look at the University of Notre Dame’s Campus Crossroads project, a $400-million plus effort to bring premium seating, a large video board and high-density Wi-Fi to a venue that came to life in 1930, according to university history.

While we will have a full report on our visit to Notre Dame Stadium in our upcoming Fall STADIUM TECH REPORT issue, we wanted to give you a “first look” at the new facilities, which basically include three new large buildings built into the sides of the existing structure, to provide support for the video board as well as two expanded premium-seating and press box areas on either side of the field.

Wi-Fi AP overlooks a concession stand

One of the coolest parts we saw were the new rooftop premium seating areas, where you can sit on a couch and see the full field while also peering out over the edge of the stadium to see Touchdown Jesus, the Golden Dome, and the rest of the world (well, OK, mostly South Bend, Indiana) while enjoying your favorite beverage and speedy Wi-Fi.

The new Wi-Fi network design using Cisco gear was led by AmpThink, and includes custom-designed enclosures for railing-mounted APs that feature a sharp version of the “ND” logo known to any football fan. Though the network hasn’t yet been optimized or tested with a full house of fans, we were still getting solid up/down signals in the 60-70 Mbps range throughout the building, even in low and high bowl seating areas. There is also a new neutral-host DAS in the stadium, built by Crown Castle. According to Notre Dame, Verizon Wireless and AT&T will be live on the cellular network by the start of the season, with T-Mobile to follow soon.

Like we said, look for more details in our upcoming report… but for now enjoy some scenes from Sunday’s game!

Ready or not, Unlicensed LTE is here. What should your venue do?

There’s much excitement around the coming of “unlicensed LTE” and for good reason. In our anytime, anywhere world the last device many of us use at night, and the first one we pick up in the morning, is a mobile phone, tablet or computer. Although much of the time our devices connect via Wi-Fi, when we’re in transit we depend on cellular.

With consumers quick to express their disappointment when their apps fail to respond – or don’t respond fast enough – on a wireless network, cellular providers are keenly aware they must keep pace with rapidly escalating user experience expectations. Research suggests mobile data traffic will grow by 47 percent annually through 2021. Combine the two and the drivers for expanding network capacity are clear.

While the lure of more bandwidth can be attractive, stadium and venue operators need to carefully evaluate the technological impact and operational overhead unlicensed LTE introduces.

Gigabit cellular coming soon

Editor’s note: This post is part of Mobile Sports Report’s new Voices of the Industry feature, in which industry representatives submit articles, commentary or other information to share with the greater stadium technology marketplace. These are NOT paid advertisements, or infomercials. See our explanation of the feature to understand how it works.

To provide gigabit speeds, the cellular industry has enhanced LTE technology to bond multiple channels together, called “carrier aggregation.” Although originally designed only to combine different licensed frequencies, it has now been extended to aggregate licensed spectrum with 5 GHz unlicensed spectrum (where Wi-Fi operates). Two competing technologies for doing so have emerged, with notable differences when deploying in high-density environments like stadiums in the U.S.

LTE-U (LTE in the Unlicensed Spectrum) is a proprietary technology, developed by the LTE-U Forum, a consortium of several cellular-related companies. It enables simultaneous operation of LTE over both licensed and unlicensed spectrum by aggregating the bands together, resulting in a performance boost. However, the way LTE-U takes control of a channel – while legal in the U.S. – is controversial and may significantly degrade performance of Wi-Fi equipment using the same channel. The Wi-Fi and cellular industries worked together to produce a coexistence test plan, but so far none of the test results for LTE-U equipment authorized by the FCC have been made public.

LAA (Licensed Assisted Access) can be thought of as the standardized version of unlicensed LTE, designed to meet European “listen-before-talk” (LBT) requirements, so it can be deployed anywhere on the planet. It was developed through the 3rd Generation Partnership Project (3GPP) worldwide standards organization, with wide participation including input from the Wi-Fi community.

Think of LBT like the telephone party lines of yesteryear, where multiple customers share a communal phone line but only one person can use it at a time for their conversation while others wait. When there is no conversation happening on the party line and two or more people try to speak at once, other customers of the party line graciously “back off” to allow one person to go first. In cellular terms, this makes LAA a more “polite” technology than LTE-U, as it waits to transmit until a channel is clear. The back-off method it uses is compatible with Wi-Fi at least on paper, although 3GPP does not require vendors to perform or publish any kind of test results.

The Road Ahead

Of course what you want to know is how the advent of LTE-U/LAA impacts your stadium and whether to add gigabit cellular to the connectivity mix.

As a robust, stable and mature technology, Wi-Fi’s strength and ability to handle exceptional stadium data traffic loads is well established. To make informed decisions about whether to consider LTE-U/LAA technologies alongside Wi-Fi, here are five essential technical considerations.

Spectrum Availability. The unlicensed radio spectrum is comprised of 24 channels in the U.S., which is analogous to a 24-lane freeway. Until now, only Wi-Fi traffic traveled on that roadway, with many years spent developing technologies to ensure steady traffic flow, particularly in stadiums. Wi-Fi includes its own LBT solution, which helps assure data merges smoothly onto the freeway. It’s been proven at six Super Bowls plus countless other concerts and sporting events.

Most stadium Wi-Fi networks are already spectrum-constrained, meaning they are just managing to carry the existing load – much less new fan technologies like AR/VR. A large body of evidence demonstrates that stadiums and arenas need 20-24 fulltime-equivalent channels to make a 5 GHz system work (regardless of technology). These Wi-Fi networks are carefully optimized to eliminate all unnecessary transmissions.

Adding one or more LTE-U or LAA systems will reduce available capacity for Wi-Fi operations. As of this writing, there are no public technical measurements of deployed systems so the actual impact is unknown. If four separate unlicensed LTE networks are actually deployed, the impact will be even greater.

Number of LTE-U/LAA Networks Required. Visitors to your stadium likely utilize each of the four U.S. cellular operators: AT&T, Sprint, T-Mobile and Verizon. Therefore, to offer gigabit cellular connectivity, you’ll need to permit all four to deploy an LTE-U, or LAA, network. Because the technologies are so new, they lack a “neutral host” methodology, so each operator will require its own separate physical network and spectrum.

Compatibility with Existing DAS. Most stadiums and arenas have either separate antenna systems for each major cellular operator or a converged neutral-host DAS. Although LTE-U and LAA are intended to support “dual connectivity” to a separate macro base station (or “eNodeB”) on paper, the products currently being shipped are intended as co-located small cells that contain two paired LTE radios – one licensed and one unlicensed. Stadium operators should validate whether their DAS systems are compatible with an expansive LTE-U/LAA small cell deployment where the primary cell (or “PCell”) is the DAS and each PCell has dozens of secondary cells (or “SCells”) providing 5 GHz service.

Cost vs. Benefit. Of no small consideration is the added amount of equipment, and the costs, in a hybrid Wi-Fi/cellular situation. If every cellular operator requires a separate LAA/LTE-U overlay, this implies up to four full new sets of equipment must be deployed under seats or on handrails. For a 60,000-seat stadium at typical under-seat densities, it would only require about 850 Wi-Fi access points (APs). In contrast, for LAA/LTE-U stadium operators would need over 3,000 additional small cells– with each one requiring a sturdy waterproof housing, a 30-watt POE connection, Cat-6 cabling, conduit and, of course, a hole drilled in the concrete. Meaning, LTE-U/LAA small cell deployments would require essentially the same physical footprint for each carrier as Wi-Fi which is likely already installed and is inherently a neutral host technolgy.

Risk. It’s also critical to consider the corresponding risks of adding up to four cellular unlicensed LTE networks to your Wi-Fi environment. It took about seven years and three full generations of radio designs for Wi-Fi vendors to perfect high-capacity stadium systems whereas LTE-U/LAA equipment is only beginning to ship. In short, it may be wise to delay comingling Wi-Fi and LTE-U/LAA networks until unlicensed LTE equipment becomes proven in less mission-critical settings than your venue.

First Look: Inside the Atlanta Falcons’ new Mercedes-Benz Stadium

We’ll have much more to report on what we saw at the press day at the Atlanta Falcons’ new Mercedes-Benz Stadium, but we thought it was important to share these views as soon as we could — so here is an extended photo essay from the newest NFL venue (which will also be used for soccer). Unfortunately the Wi-Fi and DAS networks were live but not yet optimized, so we weren’t able to do any comprehensive speed testing (but hey, that’s what a regular season game is for!).

Overalll first impressions, technology wise — this is another well thought out venue specifically from a technology standpoint but also mainly just from a visual feel. The halo board is as impressive as advertised, though we would want to see it in action during a game (while sitting in a seat) to fully judge whether or not it fits in with the flow of an event. For advertisers it’s a wonder, as watching all the video screens in the house go to a synchronized ad video was a big wow factor.

Since much of the stadium interior is unfinished concrete, there wasn’t much of an effort to hide networking components — but given all the other piping and cabling, the equipment does kind of fade out of sight in plain view.

MSR welcomes you to the big house

It’s our educated guess that the AT&T Porch — a wide open gathering area in the end zone opposite the windows toward downtown — is going to be a popular hangout, since you can see the field and have multiple big screen TV options behind you. We also liked the “technology loge suites,” smaller four-person private areas just off the main concourse with their own small TV screens and wireless device charging.

On the app side of things, it’s fair to say that features will iterate over time — both the wayfinding and the food-ordering options are not wirelessly connected yet, but according to IBM beacons are a possible future addition to the mix. And while Mercedes-Benz Stadium is going to all-digital ticketing, season ticket holders will most likely use RFID cards on lanyards instead of mobile phone tickets simply because the RFID is a quicker option. The ticket scanners are by SkiData, fiber backbone by Corning, Wi-Fi APs by Aruba, and DAS by Corning and a mix of antenna providers.

Like we said, more soon! But enjoy these photos today, ahead of the first event on Aug. 26.

Costanzo cleared in SignalShare lawsuit

Joe Costanzo, the former chief technology officer for SignalShare, has been cleared of any legal entanglements in that company’s ongoing lawsuit issues according to a new filing in the case.

Last year, NFS Leasing sued SignalShare for $7.8 million over alleged fradulent leases, a case now tied up in SignalShare’s subsequent bankruptcy proceedings. Costanzo, who primarily ran the technical operations of the stadium Wi-Fi leasing operator, was personally named by NFS in the lawsuit along with other SignalShare executives; Costanzo, however, claimed he was misled by his own company and had filed counter-claims against NFS.

A new document from the United States District Court in the District of Massachusetts said that NFS Leasing has dismissed all of its claims against Costanzo “without costs to either party.” Costanzo, who had filed a counter-claim against NFS, also dismissed his action.

Costanzo also apparently reached an agreement with the former SignalShare, according to a legal document filed by a company called M2 nGage, which was formed out of the remnants of SignalShare. According to the document, “Any disputes between Costanzo, the SPHC Parties and SignalShare were settled pursuant to a settlement agreement executed between the parties. Pursuant to the terms of the Settlement Agreement, the parties mutually released each other from any claims and SPHC agreed to pay Joseph Costanzo $92,000 over a period of a year associated with amounts due.”

NFS Leasing did not respond to an email inquiry for more information.

NFL Wi-Fi update: Cox Business signs tech deal with Arizona Cardinals; Panasonic replaces Extreme at Philadelphia’s Lincoln Financial Field

The Arizona Cardinals and Cox Business announced a new multi-year agreement that makes Cox Business the “exclusive technology solutions provider” for the team and its home stadium, the University of Phoenix Stadium in Glendale, Ariz. The new deal sees Cox Business replacing CDW as the main integrator for technology deployments at UoP Stadium, a venue that regularly sees big-time audiences for NFL games, Super Bowls, and the Fiesta Bowl.

While the Cardinals and Cox Business have been partners since 2006, the new deal calls for Cox Business to add in support and development of the stadium’s Wi-Fi and networking infrastructure, as well as to provide technical support. Previously, CDW handled those tasks at UoP Stadium.

On the other side of the country, Panasonic’s nascent big-venue Wi-Fi business got a win when the Philadelphia Eagles selected Panasonic to replace the Extreme Networks Wi-Fi deployment inside Philly’s Lincoln Financial Field this offseason. Though the Eagles declined to comment on the new deployment to MSR at this time, John Pawling, the team’s vice president of information, had this to say in a Panasonic press release:

“Upgrading Lincoln Financial Field’s Wi-Fi network is all part of our team’s ongoing commitment to providing the best in-game experience for our fans,” Pawling said in what Panasonic said was a prepared statement. “Our hope is that by staying ahead of the curve and collaborating with global leaders like Panasonic, we will have the ability to take the fan experience to the next level.”

Extreme, whose gear is currently used in nine other NFL venues, was part of a Wi-Fi deployment at the Linc done back in 2013, part of at $125 million renovation done at that time. Neither Extreme nor the Eagles would comment about the switch to Panasonic.

Wireless connectivity strong at Colorado Rockies’ ‘old’ Coors Field

For someone who covered the origin of major league baseball in Denver, it somehow doesn’t seem possible that Coors Field, home of the Colorado Rockies, is the third-oldest stadium in the National League. But after venerable venues Wrigley Field and Dodgers Stadium, there sits Coors as the next-oldest in line.

Opened in 1995, the brick-and-steel venue in Denver’s lower downtown has another oldest-type attribute, in the fact that Coors was one of the first MLB stadiums to get a Wi-Fi network built for it by MLB’s Advanced Media arm, a deployment that went fully live in time for the 2015 season. Like its bricks-and-mortar host, the “old” network is still doing fine, even if it was built without some of the newer technology and techniques that have appeared in stadium networking in the lifetime of the past couple years.

With an opening-day Wi-Fi data total of 2.2 terabytes used, Coors Field’s Wi-Fi network is more than ready and able to handle any increases in activity that may or may not be related to the Rockies’ resurgence on the field, where the purple players have spent most of the season so far in playoff contention.

During an early May visit, Mobile Sports Report found the network performing strong throughout the venue, with many 60+ Mbps readings for Wi-Fi download speeds in all seating areas as well as on heavy-traffic concourses. What follows here is some history of the park and its role in the MLBAM Wi-Fi rollout, as well as our random speedtests from a visit during a doubleheader with the defending World Series champion Chicago Cubs, whose well-traveled fans add to the capacity in any ballpark where the team happens to be playing.

One of the earliest in ‘downtown parks’ resurgence

Editor’s note: This profile is an excerpt from our latest STADIUM TECH REPORT, our Summer 2017 issue that has in-depth profiles of network deployments at the Atlanta Braves’ new SunTrust Park, new Wi-Fi for Westfield’s Century City Mall in Los Angeles, and a profile of a new Wi-Fi network at Red Bull Arena.

A little personal history for yours truly intersects with the origin of Coors Field — way back in 1991, I was one of the lead baseball writers for the Boulder (Colo.) Daily Camera, and our main story that spring was the question of whether or not Denver would land one of the two NL expansion franchises soon to be awarded. Like many other cities and regions hopeful for pro sports, Denver and Colorado voted for a tax that would help build a new baseball-only park, which looked great in those artist-concept sketches that are always floated around.

But for me what really hit home was when the team behind Denver’s bid actually went out and chalked out a baseball field in the vacant lots where Coors Field would actually sit, among the old brick warehouses in the city’s lower downtown neighborhood. On the day of the official National League visit, there was even a group of kids playing baseball on that field — whether it was staged or not, the presentation was cool, and it probably stuck in the minds of many others like it did in mine, that a downtown park would be a great thing in Denver.

After being awarded the franchise and playing a couple years in the old Mile High football stadium, the Rockies finally moved into their new home for the 1995 season, in a building inspired by Orioles Park at Camden Yards, the downtown venue built for the Baltimore Orioles a few years earlier. My first impressions at the time were favorable, noting the wider concourses and seats tilted to the action on the field, along with a ballpark brewpub as being good trends for others to imitate.

Fast forward 20 years, and at Coors Field, lots has changed from the fan perspective. With personal digital devices everywhere, and fans wanting to use social media to share experiences, the home of the Rockies is no different from any other large sports or entertainment venue in needing solid connectivity. As perhaps befits the pro sport with the best digital league-wide plan, MLB’s advanced media arm (MLBAM) in 2014 embarked on a program to make Wi-Fi and DAS deployments happen in every stadium that didn’t have them (or had older. underperforming networks). By cutting deals with carriers and equipment suppliers and teams. MLBAM put together $300 million in the kitty for a buildout that reached 23 stadiums by this year’s ASG.

Some orderly DAS wiring coming out of the head end room.

(Some teams, like the San Francisco Giants at AT&T Park and the Atlanta Braves at new SunTrust Park, have opted to build their own physical networks, even while working closely with MLBAM on matters like the league-wide Ballpark app.)

Coors Field was among the very first in the MLBAM buildout efforts, with fan-facing Wi-Fi available in time for the 2015 season. Though its buildout predated some of the newer techniques and technologies used for stadium Wi-Fi deployments — like under-seat or handrail-mounted Wi-Fi APs — our tests showed the Coors Field Wi-Fi network, which now has approximately 550 APs, to be as strong as any we’ve tested, with signals in the 60 Mbps download range throughout most of the park. We didn’t test all the DAS carrriers but from all appearances, AT&T, Verizon and T-Mobile are well represented on the AT&T-built cellular network. According to AT&T there are 322 antennas in the newer version of the DAS, also built in 2015, which AT&T said has roughly six times the capacity of the previous network.

As the Rockies enjoy an on-field resurgence (Colorado was in or near first place in its division through most of the spring and remain in the wild-card hunt as of this writing), fans should be happy to know their connectivity is competitive as well, with both team IT types and MLBAM keeping an eye on keeping customers connected.

Deck locations help ‘front to back’ work well at Coors Field

With three main tiers of seating, the 50,398-seat Coors Field has plenty of overhangs to work with as antenna mounts, making the so-called “front to back” design philosophy work well. Michael Bush, senior director of information systems for the Rockies, led us on a tour of the stadium, noting that at the tops of most seating areas there were two antennas, one pointing straight down and a “Gillaroo” panel antenna pointing down the rows of seats.

Good camoflauge on antennas serving the left field bleachers area.

At the bottom of most seating areas, including close to field level, there are Wi-Fi APs mounted either on the playing-field walls, or on the railings in the upper decks, pointing back up the rows of seats. In section 131, right behind home plate, we got readings as high as 63.10 Mbps on download and 48.75 Mbps for upload, almost exactly halfway between field level and the concourse at the top of the lower bowl.

In row 16 of section 138, behind the Rockies’ dugout, we got a speedtest reading of 63.32 / 41.63 Mbps, and in the outfield seats behind the left-field foul pole we saw speeds of 68.29 / 49.66 Mbps. Up in the “Rockpile” seats, way up top in straightaway center, we still got a Wi-Fi mark of 66.69 / 41.44 Mbps, probably from one of the four antennas we saw mounted on the back-side railings.

In the back of the walk-around “Rooftop” club and bar area in the upper deck of right field we got speeds of 61.21 / 28.86 Mbps, and then marks of 61.52 / 40.53 Mbps when we moved around to the front of the Rooftop, where you can lean on a railing while watching the game below. The lowest marks we got were in the upper deck of section 317 along the first-base line, where the speeds were 42.16 / 25.33.

All of these tests came during a break between games during a doubleheader versus the Cubs, when the stadium was cleared between games. The marks also varied between being on the main Rockies fan Wi-Fi SSID, and one reserved for Verizon Wireless customers, which our device kept autoconnecting to. But even as the stadium filled up for the nightcap, our signals stayed strong, including a 67.62 / 29.78 Mbps mark up in section 342, in the upper deck along the third-base line.

On Verizon’s LTE network we got a reading in the left-field bleachers of 14.99 / 15.19 Mbps, and a reading of 11.26 / 7.69 Mbps up in front of “The Tavern,” one of the bars in the Rooftop area. We did not have devices to test cellular signals for AT&T or T-Mobile, both of which like Verizon are also on the stadium DAS. Sprint, according to Bush, serves its Coors Field customers with a macro antenna deployment on a rooftop across the street from the stadium along the first-base side.

In our tour of the venue, Bush led us down to the head end rooms, where the DAS deployment looked military in its precision and organization. He also pointed out the cooling vents, which went from field level through the ceilings to finally pop out above the concession stands on the main concourse level, out of view for anyone who wasn’t trying to look down to see them.

Though Coors Field’s lower level seemed to have more than enough room for head end rooms, Bush did show us the parking lot “shed” that MLBAM built to house its video operations, including the on-field replay system that shuttles signals back to league headquarters. There is also some Wi-Fi coverage outside the building, mainly in the north parking lot which doubles as an area for media tenting for large events like postseason games. But for the most part Bush said Coors Field is careful to limit its Wi-Fi footprint to the facility’s walls, so there isn’t any bleed-over use by the residential and commercial buildings that are just across the street from three sides of the stadium.

Making sure the tech fits the park

As one of the first MLBAM deployments, the Coors Field network might have been excused for being more functional than aesthetic, but as our visit showed the opposite is true. Unless you are explicitly looking for Wi-Fi and other networking gear, it’s hard to see with the naked eye. In our unofficial wanderings we’d put Coors Field among the best in terms of hiding things in plain sight, with exact paint color matches as well as finding locations for mounting where gear doesn’t stick out. Helping out with this task is Coors Field’s overall embrace of brick and exposed steel beams, a sort of benign camoflauge that the network deployment team made good use of.

“A huge part of the fight” was making the antennas and other gear disappear, Bush said, pointing out several deployment spots we otherwise might have missed (including a huge bank of DAS gear right above a concession stand, perfectly painted to blend in with the green structural steel right above).

“The owners wanted to make it look like it [the network] was always there from the start,” said Bush.
