When you visit Memorial Stadium in Lincoln Neb. you can’t avoid a history of devotion to football and fans. The stadium itself still contains much of its old bones dating back to its inception in 1923, and when the red-clad faithful assemble for their football ceremonies, you can see generations of fans loyal to the Cornhuskers streaming in to fill the nearly 90,000 available seats.

Aside from the five national championships and many years of top-level success, the university takes care of the people responsible for sellouts dating back to the 1960s by keeping the stadium up to date with high-definition connectivity, inlcuding both cellular and Wi-Fi networks, and a wide range of digital displays for visual information and entertainment. In a recent visit to Memorial Stadium for a Saturday day game, Mobile Sports Report found excellent connectivity, especially on the Wi-Fi network, even in some areas where construction materials and stadium design presented unique challenges to wireless communications.

Nebraska fans have found the Wi-Fi as well, as according to statistics not released previously by the school Nebraska saw one game last season with 7.0 terabytes of Wi-Fi data used. Nebraska also saw a 6.3 TB game last season and started off 2018 with Wi-Fi totals of 6.3 TB and 6.2 TB, the first coming at a game that wasn’t even played due to massive rain and thunderstorm activity that canceled the event just after kickoff.

The connectivity reach even stretches out to some of the football parking lots, where external Wi-Fi AP placements keep fans connected while they are tailgating. What follows here is an on-the-scene description of what connectivity and the fan experience looks and feels like on yet another sellout day, this one from the Sept. 8 game versus old rival Colorado.

Even the day before the game, there was noticable excitement in Lincoln for Nebraska football, with groups of fans roaming around outside the stadium while VIP tours were taking place inside. On game day itself, the connectivity experience starts in the parking lots, where MSR saw Wi-Fi gear on light poles and sides of buildings that was clearly there to cover the tailgating activities. Stopping to check it out we found and quickly connected to the FanXP SSID, with no splash screen or email login required, just a quick connection to fast bandwidth. Throughout the day, the FanXP network connected and reconnected no matter where we roamed, or if we turned Wi-Fi off and on (as we do to test cellular signals).

With perhaps one of the most devoted fan bases in any sport — the team and the stadium have a record sellout streak dating back to 1962 — the Husker sports operation is well funded, meaning they don’t have to bother with concerns about whether or not Wi-Fi or other technologies produce any direct returns on investment. In turn, the school rewards its fans by staying at the forefront of stadium technology deployments, including being the first college stadium to install video boards, back in 1994. Wi-Fi using Cisco gear was first brought to Memorial Stadium for the 2014 season, and has since then gone through various upgrades and tunings, and now has 855 total Wi-Fi APs in the venue and the surrounding parking lots.

The current video board over the north end zone (which was the largest in the country when it was first installed) now is even sharper to look at, having gone through an upgrade last year from 20 millimeter pixel density to 10mm. Last year also saw the introduction of two two-sided “wrap-around” video screens on north sides of the east and west sections, providing video viewing for fans in the north stands who previously had to turn all the way around to see a screen. The north tower screens, as well as two other similar flat screens on the south sides of the east and west stands all also have 10mm pixel sharpness.

Also before last fall, ribbon boards on the east- and west-side balconies were replaced with 16mm displays that run the full length of the structures. An additional ribbon board was also added to the middle east balcony, providing even more inventory for messages, advertisements and game information. Overall, the venue has approximately 1,400 screens of various sizes and shapes to bring game day action, concessions menu and other communications to fans there for game day. Nebraska uses Cisco’s Cisco Vision (formerly known as Stadium Vision) to manage and operate all its digital signage from one central control.

North and South stands the biggest connectivity challenge

With the gates open and the stadium starting to fill up, MSR went directly to the north stands, which Nebraska IT operations manager Chad Chisea and director of information technology Dan Floyd had previously told us was the most challenging area to cover with wireless connectivity. With extremely wide rows of bench seating and no overhangs for antenna placements, Nebraska brought in small Wi-Fi antenna enclosures from Ventev and mounted them onto small “p-railings” that dot the aisles. The area is also covered by Wi-Fi antenna placements on top of the scoreboard structure pointing down.

Though the section wasn’t completely full when we tested it, we still got a strong Wi-Fi mark of 28.5 Mbps download and 19.8 Mbps upload about halfway up the west corner side of the north stands. In another spot on the east side we got a test mark of 28.0 Mbps / 12.2 Mbps; and in possibly the hardest place to cover, as far as we could get from an aisle or the scoreboard, we still got a Wi-Fi test of 11.0 Mbps / 13.1 Mbps. DAS coverage for Verizon 4G LTE at the same spot was 16.9 Mbps download, but just 1.40 Mbps upload.

With more and more fans finding their way inside, we tested several spots on the concourses and found them with extremely strong coverage, including one mark of 63.8 Mbps / 61.1 Mbps just inside Gate 7. The concourse areas in several parts of the stadium are very architecturally interesting since there are some places where newer construction was simply placed outside the older structures, producing a kind of stadium-inside-a-stadium effect. Originally, the IT staff thought that Wi-Fi APs on the newer outside walls would be able to bleed through the old structures, which had glass windows along the old outside walls; but because those windows contain leaded glass (which shut out the Wi-Fi signals), Nebraska was forced to install APs on either side of the old walls.

Such attention to detail and a clear desire to keep fans connected no matter where they roam was evident in other places as well, such as finding strong Wi-Fi connectivity (30.6 Mbps / 15.2 Mbps) even while taking escalators up to the top levels of the east stands. In the top 600-level concourse we got Wi-Fi readings of 25.5 Mbps / 11.6 Mbps, and in row 5 of section 607 — about as high as you can go at Memorial Stadium — we got a Wi-Fi reading of 18.2 Mbps / 10.6 Mbps, most likely from the antennas mounted on the top railing of the stadium or on the LED light fixtures that also poke up from the east side.

Just before kickoff, we were in the middle of the lower-bowl seats on the west side of the stadium, where most fans were standing, phones ready to record the Cornhuskers as they came out of the locker room and took the field. With APs mounted on field-level railings pointing up probably providing coverage, we got a mark of 7.73 Mbps / 1.74 Mbps in the fifth row of seats.

Wi-Fi usage among the top of all venues

According to Floyd, only Verizon Wireless and T-Mobile use the stadium’s DAS network, which was built by Verizon. Since Verizon dominates the customer base of the Lincoln, Neb. area (Floyd estimates it has about 70 percent of the market), the other major carriers haven’t seen the need to participate in the DAS; instead, U.S. Cellular built a platform for macro antennas inside the north scoreboard area, and AT&T and Sprint use that area for similar deployments. For backhaul bandwidth for the Wi-Fi, Chisea said Nebraska has one circuit that transmits between 1.5 and 2 Gbps, along with a backup circuit that can carry 500 Mbps of traffic.

Children of the corn get ready for game day

And all those circuits and antennas got a free stress test during Nebraska’s first scheduled game of the season, a Sept. 1 contest against Akron that was cancelled almost immediately after kickoff when severe thunderstorms moved into the area. While the fans didn’t get to see any football, according to Floyd many stuck around for a considerable amount of time, using a full regular-game amount of wireless data — 6.3 TB of Wi-Fi — doing things like taking live Facebook Live video streams of the storm.

“If you looked at the network stream that day it was absolutely full,” Floyd said. For the Colorado game (a 33-28 Colorado victory), Nebraska reported 6.2 TB of Wi-Fi data used, with 34,728 peak concurrent connections on a day with 89,853 announced attendance. The top Wi-Fi game so far for Memorial Stadium, a 7.0 TB mark recorded on Sept. 2, 2017, saw 36,892 peak concurrent connections for a game with 90,171 in attendance. Nebraska saw an average of 5.93 TB and 31,115 peak concurrent connections per game in 2017, according to statistics provided to us by the school. An Oct. 7, 2017 game against Wisconsin also saw 6.3 TB of Wi-Fi data used.

With a constant attention to detail and a devotion to good network performance (during the Colorado game, MSR saw the Nebraska IT staff identify and fix a Wi-Fi network configuration issue that briefly impacted upload speeds) the Nebraska IT staff treats its stadium networks like a coach treats a team, always looking for ways to improve. So no matter what happens on the field, the faithful fans who fill the venue every game day can rest assured that if and when they want to use their mobile devices to connect, the Memorial Stadium networks will take them wherever they want to go.

Chargers, Mobilitie pump up the DAS at StubHub Center

Mention StubHub Center to your average sports fan in southern California and they’ll likely assume you’re talking about soccer’s LA Galaxy or the Los Angeles Chargers, the recently relocated NFL franchise subletting space while its permanent stadium gets built.

But StubHub Center, built on the campus of California State University/Dominguez Hills, also includes a velodrome, an 8,000-seat tennis stadium (with several adjacent courts), and an outdoor track and field facility. Throw in the far-flung parking lots and it adds up to 125 acres that all need wireless connectivity.

With such wide spaces to cover, StubHub management opted not to spend on fan-facing Wi-Fi and instead focused on distributed antenna system (DAS) technology to keep fans and tailgaters connected. Katie Pandolfo, StubHub’s general manager, looked to the major cellular carriers to invest in and support the connectivity needs of Galaxy and Chargers fans, and other eventgoers at the open-air StubHub.

Carriers help bear the cost of connectivity

Katie Pandolfo, StubHub’s general manager

“With our DAS-only approach, the investment is 100 percent on the carriers and doesn’t cost us anything,” Pandolfo told Mobile Sports Report. While they got a few complaints about no public Wi-Fi during events in 2017, when the 29-zone DAS system was activated, fans quickly acclimated and now use bandwidth from Sprint, T-Mobile and Verizon on the shared network. AT&T isn’t part of the DAS system, but has operated a macro site at StubHub for years, according to Pandolfo.

Mobilitie helped build StubHub’s DAS system and offered its engineering expertise; the turnkey provider also manages the system. The DAS-only approach is common in southern California; in addition to the Rose Bowl in Pasadena, the Honda Center in Anaheim and Viejas Arena (under construction) at San Diego State University are also DAS-only venues with no fan-facing Wi-Fi.

StubHub Center, located in Carson, Calif., is 17 miles south of downtown Los Angeles, and upwind from a nearby Goodyear blimp mooring station; gusty coastal winds apparently make this a good training ground for new blimp pilots. The 27,000-seat StubHub originally opened in 2003 as Home Depot Center; the new sponsor came onboard in 2013. Anschutz Entertainment Group owns and operates StubHub Center.

StubHub will handle several events when Los Angeles hosts the Summer Olympics in 2028, including bicycle track racing, field hockey, pentathlon, rugby and tennis. Pandolfo expects firmer plans for the venue’s technology needs to emerge sometime in the next couple years. Technology – especially wireless technology – will change a lot in that time, she noted.

As the second soccer-specific stadium built in the U.S., Major League Soccer’s LA Galaxy is the venue’s premier tenant. But in 2017 when the National Football League’s Chargers moved from San Diego to Los Angeles, the facility underwent some major upgrades. Additions include 1,000 new tip-up seats replacing bleachers on the east side of the stadium; another 330 bleacher seats were added in StubHub’s southeast corner. Luxury suites and the press box were renovated along with two new radio booths; they also added a security office for police and NFL officials, and camera booths at the two 20-yard lines and at the 50-yard line. Locker rooms were enlarged as was the press conference room.

DAS antennas look down from atop a wall

And tempting as it may be to lump all fans of any sport into a single heap, Pandolfo said Galaxy fans and Chargers fans behave very differently at StubHub Center. Chargers fans like to get up and walk around, visit concessions and take advantage of the venue’s amenities during the game. Not so for Galaxy fans, who tend to stay seated and don’t want to miss any of the action, she explained.

California’s Department of Alcoholic Beverage Control also just changed its rules and will now allow beer sales up and down the aisles of stadiums like StubHub Center. Beer hawking, she noted, didn’t used to be digital and required fans to pay cash. “Now it’s a quicker transaction that improves the fan experience,” using mobile pay systems or credit cards, Pandolfo said.

DAS upgrades mean faster speeds

In the meantime, Mobilitie continues to optimize StubHub’s DAS system; based on bandwidth speed tests conducted by Mobile Sports Report, things are moving in the right direction. MSR tested Verizon DAS connectivity right after the system was installed in August 2017, and a year later during a Chargers’ pre-season game against New Orleans. In 2017, Verizon’s DAS struggled in single-digit Mbps uploads and downloads; quite often, the throughput was even less.

What a difference a year makes. Mobilitie engineers’ fine-tuning has paid off; August 2018 tests show dramatic improvement, with the highest throughputs near the stadium’s northwest concessions area — 111.39 Mbps/12.15 Mbps (download/upload). A year previous, things were a lot more sluggish with 0.95 Mbps/0.04 Mbps speeds recorded in the same area.

Overhangs provide good places for equipment mounts

DAS performance has also improved just inside the gates past the ticket scanners at the bottom of the stairs; in 2017, we clocked only 1.87 Mbps/13.42 Mbps, but more recently throughput had jumped to 87.08 Mbps/21.42 Mbps. The concession area on the east side of the stadium checked in most recently at 76.55 Mbps/6.7 Mbps, another sizeable increase from last year when Verizon DAS throughput was a pokey 0.4 Mbps/0.06 Mbps.

Speeds inside the stadium have also improved year-over-year. Section 230 in the northeast corner of StubHub measured 2.83 Mbps/1.96 Mbps a year ago, but were up to 13.48 Mbps/8.71 Mbps in August 2018. Similarly, the sunny northern end of the stadium above the end zone delivered 0.21 Mbps/0.27 Mbps a year ago, but jumped to a more acceptable 16.44 Mbps/18.27 Mbps. The east side of the stadium is also more robust; a year ago, bandwidth tests yielded 3.1 Mbps/0.01 Mbps, but were up to 8.97 Mbps/1.74 Mbps.

Improvements to the DAS network performance can only help improve the fan experience at StubHub Center. Pandolfo wants fans to be able to do everything faster: Get parked faster, enter the stadium, and take advantage of all the food, drink and merchandise options. “We look at the whole package and then at the network we have to provide to make that happen,” she said. “We’re looking at it from the fan experience but also how to optimize revenue for the building.” It’s the right formula for sporting venues compelled to balance technology requirements against dollars and cents.

LAFC scores technology hat trick at Banc of California Stadium

There’s an elegance to the advancing striker – the foot work, feints, arc of the kick – as they target the opponent’s goal. For the Los Angeles Football Club, that elegance gets reflected back in its newly christened home field, Banc of California Stadium, with its graceful lines and minimalist design, plus visibility and a connection to the field rivaling venues half its size.

LAFC, one of Major League Soccer’s newest expansion teams, had a particular sort of experience in mind for fans inside the venue, with its capacity of 22,000. The steeply pitched stands create an intimate sporting and entertainment space. Multiple clubs, suites and concession areas are there to satisfy food and beverage desires. Team owners were equally adamant about having top-notch technology, according to Christian Lau, vice president of information technology for LAFC, especially where wireless networking was concerned. The requirement was for “unprecedented coverage,” he added. “We wanted to avoid doing any retrofitting for at least five years.”

Opened in April, LAFC’s gleaming new stadium sits adjacent to the Los Angeles Coliseum (home to USC football, and to the NFL’s Rams, at least for now), replacing what used to be the Los Angeles Sports Arena. That structure was demolished in early 2016 and LAFC’s lengthy list of owners (Peter Guber, Magic Johnson, Will Ferrell and Mia Hamm, to name just a few of the sports and entertainment luminaries with a stake in the team) set the timer for April 29, 2018, LAFC’s first home game for its inaugural season.

Construction crews worked relentlessly to meet the deadline; the venue was ready one month early, thanks to good planning and construction crews putting in 16-hour days to be ready for BofC Stadium’s debut. On April 29, the gates opened and a new era had begun with the ‘hat trick’ of a fiber backbone, solid wireless coverage and an advanced app strategy.

The optics of LAFC networking

No doubt where you are at. Welcome to LA… FC.

The foundation for LAFC’s networking is a gigabit passive optical network (GPON) backbone with two chassis, plus fiber links from two service providers, AT&T and Crown Castle. The stadium backbone is 10-Gbps fiber with 100-Gbps dark fiber in place, Lau explained. LAFC is one of just a few sporting venues using GPON, along with Mercedes-Benz Stadium in Atlanta, and Texas A&M’s Kyle Field in College Station. Perhaps not coincidentally, the technology contractor for all three projects was IBM.

Wi-Fi was an obvious requirement for BofC Stadium; back-of-the-house networks support ticketing processes at the gates, along with POS applications and LAFC administrative needs. Fan-facing Wi-Fi (“LAFC Guest”) blankets the venue with 487 access points; Lau’s leaving open the door to add more APs as requirements dictate. About 60 percent of the existing APs are installed under seats in the stands. Ruckus Networks is the Wi-Fi AP vendor and helped with system engineering and tuning.

While engineered for 70,000 users, the venue’s Wi-Fi has been averaging about 8,700 simultaneous users, according to Lau. The LAFC Guest network has no landing page since at some venues, loading times for landing pages can be long, leading to frustrated users abandoning the Wi-Fi. Users have also come to consider Wi-Fi a de facto amenity, so LAFC wanted to ensure its guest Wi-Fi network was easily and quickly accessible, Lau said.

The DAS details

On the cellular side, LAFC called on wireless services and engineering firm Mobilitie to pull together the distributed antenna system (DAS) for BofC Stadium. The venue’s DAS network consists of 25 zones powered by Ericsson gear; there are 160 antennas and over 7 miles of cabling to handle nearly 1.5 million square feet of DAS coverage.

Wireless gear covers the concessions areas

All four of the major wireless carriers — AT&T, Verizon, T-Mobile and Sprint – have signed up for BofC’s DAS network. Verizon was on air for the first game; Sprint was scheduled to fully integrate into the DAS network by the end of June, according to Stephanie Gray, senior director, wireless coverage solutions for Mobilitie.

LAFC was looking something transformative in its use of technology that would set BofC stadium apart from other stadiums, Gray told Mobile Sports Report. LAFC wanted seamless wireless especially in transition zones, part of strict requirements for the DAS network.

“They wanted a high percentage of coverage throughout the venue, particularly where people are using SeatGeek and wireless/paperless ticketing at the gates,” she explained. “We needed optimum coverage that could handle the stadium under load.”

Mobilitie brought engineering know-how to deal with the inevitable onsite quirks unique to every venue. In the case of BofC Stadium, the overall design aesthetic is modern and slick. The ceiling materials in many parts of the stadium – clubs, suites and some concession areas — are sheathed in metal, which presents an RF propagation challenge for RF, reducing signal strength.

On-field DAS coverage was also challenging, according to Jamie Witherspoon, director, technical solutions, for Mobilitie. Antennas had to be mounted on stadium trusses before the trusses were craned into place, an unusual technical cart-before-the-horse process. The reason? Cherry-picker equipment couldn’t be on the field or its freshly laid sod to adjust DAS antennas. In addition, Witherspoon reported lots of negotiations with the architecture firm, Gensler, to ensure the DAS antennas were as unobtrusive as possible and to preserve the stadium’s design aesthetic.

“With DAS, we’re more accustomed to building out a pre-existing venue, coming in after the fact,” Witherspoon explained. “This was brand new construction, so we had to work around multiple construction teams.”

Bandwidth snapshots

Mobile Sports Report put the fan-facing Wi-Fi and DAS to the test at BofC Stadium’s opening day, a match between LAFC and the Seattle Sounders. We sampled upload and download speeds around the stadium using the Speedtest app to measure performance. All our tests are only from Verizon’s services inside the venue.

Underseat mounts for Wi-Fi

In general, the BofC wireless services appear well engineered and cover the stadium’s common areas effectively. As to be expected, bandwidth performance was higher in the areas around the suites and clubs, where Wi-Fi downloads clocked in anywhere from 12.38 Mbps in the Sunset Loge on the west side of the stadium to 15.26 Mbps in the Founder’s Club. Wi-Fi upload speeds came in at 63.92 Mbps and 71.94 Mbps, respectively, the highest speeds measured in our tests at BofC Stadium.

Verizon’s DAS wasn’t as fast as the guest Wi-Fi. Highest DAS download speed at the south concessions was 37.67 Mbps; Section 123 on the southern side of the bowl came in at 35.43 Mbps. Highest upload speed for DAS service was 21.42 Mbps in the southeast concession area, followed by 20.92 Mbps around the southwest concessions.

A couple areas were less robust from a wireless bandwidth perspective. The DAS performance in the concession area outside the Figueroa Club on the east side of the stadium measured 9.4 Mbps download/10.97 Mbps upload; guest Wi-Fi in the west concessions area came in at 8.58 Mbps/1.93 Mbps, while Wi-Fi in the south concession wasn’t much better at 8.27 Mbps/1.98 Mbps. But generally, the guest Wi-Fi outperformed Verizon’s DAS and most Wi-Fi download/upload speeds were in the double-digits of megabits per second.

Prepping the LAFC app

LAFC worked with mobile integrator Venuetize to build out the team’s app, using the MLS team app template as its foundation. As a new team and one that started its season with a succession of away games, there was no reason to have stadium-based features in the app’s first iteration, said Lou Fontana, vice president of project management for Venuetize. The earliest iteration of the LAFC app concentrated more on content pieces, followed by the BofC Stadium-specific features.

LAFC’s app features both mobile ticketing and a sophisticated digital wallet for making onsite purchases for food or team merchandise. LAFC’s Lau volunteered that the organization is looking to have totally digital ticketing by 2019 – no paper, no PDFs to print out. Venuetize did some backend integration with payment processing partner Vantive; the ticketing part of the app works with ticket marketplace and aggregator SeatGeek.

Wi-Fi APs point down from the rafters

The LAFC app also uses and artificial intelligence-powered chatbot named Otto to help with stadium info, developed by Satis.fy. A future iteration of Otto will take it out of the Web’s view and make it a native view, incorporating elastic search. “That will enable fans to ask about players and the team schedule, and will replace search function in the app,” Fontana said, adding the upgrade could come sometime this summer.

The current version of the app has video, served up from MLS’s site. Immediate replay is something Venuetize will work on with LAFC. “When is the video content source available? That’s an issue,” Fontana said, adding that scoring plays make it out of the MLS server within about 25 minutes. While Venuetize could take that content and make it native, it’s not a top priority for the team at the moment.

BofC Stadium has installed Bluetooth beacon technology. “We haven’t gone through process of dialing in beacons, but wayfinding and navigation are on the list” for the LAFC app, Fontana said.

The integrator is also looking at GameChanger MVP, an augmented reality game developer, for a scoreboard game to fold in. “AR gaming will be the next interesting thing” for sports apps generally, according to Fontana.

Connect the DAS: Enhanced cellular finally arrives at Wrigley Field

When it comes to sports fans and their beloved stadiums, change is sometimes hard to take, especially at historic venues like the Chicago Cubs’ beloved Wrigley Field.

The last ballpark in the major leagues to get lights (in 1988), fans of the iconic Wrigley with its ivy-covered outfield walls put up some fierce resistance to some of the latest changes brought to the ballpark by the team’s latest owners, the Ricketts family, ove the past few years. An expansion of the bleacher seats, some new video boards behind the stands in the outfield and construction of a hotel and office building adjacent to the stadium all had their naysayers, some of whom would still prefer the old to anything new.

But this season, Wrigley is finally unveiling a part of its renovation that everyone can get behind — better cellular connectivity inside the park thanks to a new neutral-host distributed antenna system (DAS) built by DAS Group Professionals (DGP) for the Cubs. Delayed a couple years from its originally planned deployment due to the Cubs’ World Series title run in 2016, the new system has contracts with all four of the major U.S. wireless carriers, and should help fans share more memories from the Friendly Confines in the seasons to come.

Success on the field makes waiting OK

First announced in 2015, the plan to bring the new DAS as well as a new Wi-Fi network to Wrigley was pushed back until this season, mainly because of the Cubs’ new-found success on the field. In addition to the World Series title in 2016 — as everyone knows, the Cubs’ first in 108 years — the Cubs also went deep into the postseason in both 2015 and 2017, reaching the NLCS in both those years. As the extended seasons pushed back all kinds of renovation construction schedules, the arrival of the new connectivity options was pushed back a season longer than expected — a delay that was felt but perhaps not minded all too much by the celebrating Cubs fans.

DAS antennas visible near tops of stanchions in lower seating bowl

Since deployment of the DAS was (mostly) fairly straightforward — the DGP deployment uses entirely overhead and side-structure antenna placements, thanks to Wrigley’s multiple overhangs — it was finished in time for opening day. The Wi-Fi network, however, will be rolled out as the season progresses, mainly due to the need to place APs under seats in the lower seating sections.

Much of the engineering to get both systems inside the stadium faced more than the regular share of stadium conflicts, as this past offseason saw the Cubs pull out almost all the lower-bowl seats and dig 60 feet down into the dirt to clear room for some under-seat club areas, one of which is already open. Even though the DAS network wasn’t powered up until about a week before the season’s first pitch, deadlines were met and the new celluar system was ready for opening day.

“We definitely put scheduling and timing to the test, but we got it done,” said Andrew McIntyre, vice president of technology for the Chicago Cubs. “By the All-Star break, we should have both systems online,” McIntyre said.

The DAS system deployed by DGP uses JMA equipment, just like DGP’s other big-stadium DAS deployments at the San Francisco 49ers’ Levi’s Stadium and the Sacramento Kings’ Golden 1 Center. Steve Dutto, president of DGP, acknowledged the challenge of the Wrigley buildout, including one instance where DGP technicians needed to set up scaffolding to mount antennas but couldn’t because instead of a concrete floor there was a 60-foot hole in the ground.

“We worked around all that and got it done,” said Dutto.

New club spaces get new flat antennas

Mobile Sports Report traveled to Chicago for a mid-April visit, hoping to get some sense of the new network’s performance on a full-stadium game day. Instead, we got a lonely and chilly tour when sub-freezing temperatures caused that day’s game to be canceled. One positive was that with empty stands, it was easier to get around and see all the DAS antenna placements.

New flat-panel DAS antenna blends nicely in club space.

The first part of our tour was a trip underground to the new 1914 Club (for the year Wrigley opened) that sits directly under the seats right behind home plate. With the feel of sports bar-meets-speakeasy, the classy premium-seat space has great connectivity even while underground, thanks in part to a new flat-panel disc-shaped omnidirectional DAS antenna from Laird Technologies that DGP used in both indoor and outdoor placements.

With nobody in the club, we got an off-the-scale speedtest of 139 Mbps down and 46.7 Mbps up, proof on one level that the system is ready to go. Since it was freezing outside (did we mention it was cold?) MSR didn’t stop to take our gloves off to get many more tests, but we did get marks in the high 30 to high 40 Mbps range pretty much anywhere we did stop, including the upper decks and the bleachers. Even out in the middle of the adjacent plaza (where the Cubs’ networks are designed to cover) we got a DAS speed mark of 38.2 Mbps / 44.0 Mbps.

“The new DAS is much more higher performance grade than in the past,” McIntyre said.

The premium-seating club spaces, which were previously nonexistent at Wrigley, will expand next year when the Cubs finish out two more underground spaces, along each base line. According to McIntyre fans in those clubs will be able to watch players using the underground batting tunnels to tune their swings mid-game.

The last phase of the current Wrigley renovations will also see the addition of some more open gathering and club areas on the upper deck level, including party porches on the outside of the stadium walls overlooking the plaza (now called Gallagher Way under a sponsor-naming deal with the Illinois-based insurance brokerage). Gallagher Way, which hosted an outdoor ice rink in the winter, is set to hold concerts and other gatherings like movie nights this summer.

Old overhangs perfect for new technology

Sometimes in stadium wireless retrofits, you get lucky and the old stuff blends pretty well with the new. Take Wrigley Field’s classic metal-and-wood overhangs, which provide shade and rain cover for fans on the lower back and upper decks. According to DGP vice president of engineering Derek Cotton, getting DAS antennas in the right spots for a good signal there was half easy, half hard.

On the top levels, DGP was able to install the JMA gear out where it could offer the best connection — at the edge of the roofs, pointing backward toward the stands. With aesthetics a top concern at Wrigley, the roofs were a perfect place to “hide” some of the 420 total antennas in the deployment.

But on the lower-level roof, DGP and the Cubs had a concession to make that will be fixed during the upcoming offseason. Because of the deep pits dug into the box seat and field level, Cotton said DGP couldn’t get a scaffolding set to reach the outer parts of the lower roof — so instead DGP put those antennas in toward the backs of the roofs, and will move them out to the edges this winter. Some other antennas installed this year will have to be taken out and replaced while the rooftop party decks get built; and by next year the Cubs hope to have all the marooned gear from an AT&T Wi-Fi deployment from 2012 removed — but if you have sharp eyes this summer you can spot some of the old “Pringles can” Wi-Fi radios still nestled up in the rafters.

‘Creativity’ needed for bleachers

If DAS deployment in the main seats at Wrigley was fairly straightforward, for the venue’s unique and famous bleacher seating DGP’s Cotton said “some creativity was needed” to find places to mount antennas.

With no overhead structure and only the historic, manually operated scoreboard in the back, Wrigley’s bleacher seating now has DAS coverage from a wide array of antenna placements that took use of just about every kind of mounting area available. Some gear hangs from the back of a sponsor’s sign in left field; other antennas are tucked underneath the bottom of the scoreboard, pointing out from a small club area there; and still others are concealed in the tall grass of the planters that go up the sides of the centerfield seating section, just next to the poles that carry the Cubs’ World Championship flags from 1907, 1908, and most recently, 2016.

Other more normal antenna placements are found around the back side of the bleachers, where recent renovations added a concessions area and more stairways.

Moving outside the park to the plaza, artistic concealment continues with antennas hidden on light poles that surround the triangular plot of lawn. According to McIntyre, the club’s wireless coverage extends across Clark Street to the new Hotel Zachary, named for Wrigley Field’s original architect, Zachary Taylor Davis.

The hotel, which has retail shops on the street level — including a McDonald’s franchise that replaces a standalone McDonald’s that used to sit in the parking lot where the plaza now stands — has DAS coverage on all floors, with Wi-Fi planned for public spaces on the first floor and second floor, where the main lobby and lobby bar reside. In the lobby bar comfortable couches provide a great place to look over the plaza and at Wrigley; and in fact the Extreme Networks Wi-Fi gear visible on the ceilings is already operative there, though purposely limited in throughput to 7.5 Mbps up and down for now.

Most of all the wiring for the new networks comes together in a small brick headend building about a block north on Clark, behind the Wrigleyville hot dog stand. Unless you knew what was inside, you’d be hard pressed to guess why there are huge strands of red, white and blue cabling coming through one wall. Just before the start of the season, the Cubs announced a deal with Comcast Business that will see a “XfinityWiFi@Wrigley” label on the Wrigley Wi-Fi SSID. According to McIntyre Comcast will bring in twin 10-Gbps pipes to power the Wrigley Wi-Fi network.

When the Wi-Fi network comes online later this season, there will be even less of a reason to believe there will be any more grumbling about connectivity at the Friendly Confines. The new era starts with the DAS deployed by DGP, which was picked by McIntyre and the Cubs several years ago, after hearing of DGP’s deployments at Levi’s Stadium and over face-to-face meetings at the SEAT Conference.

And while Cubs fans didn’t have to wait for new wireless as long as they did for a world championship, they can now start enjoying the ability to connect to the world outside the ivy.

“When it’s fully done our fans will have a real ability to share, in a modern way, from one of the most iconic and historic venues,” McIntyre said. “It’s a whole new world.”

Massive MIMO is Sprint’s path to 5G, says CTO Saw

Sprint chief technical officer John Saw has seen the future of cellular wireless, and according to him it was at a sports event.

“I was at the [Winter] Olympics where KT [Korea Telecom] and Intel set up the first 5G network,” said Saw in a recent phone interview. “Stadiums will be a good showplace for the capabilities of 5G. It’s pretty impressive what you can do with 5G that you can’t do today.”

Saw, who was CTO at WiMAX play Clearwire before that company became part of Sprint, will be the first to admit that the network built for the PyeongChang Olympics wasn’t “true” 5G, but said it was a good precursor. He also added that it wasn’t a cost-conscious deployment, something MSR had heard from other sources who said Intel and KT didn’t hold back when it came to spending.

“They spent a lot of money [on the network],” Saw said.

But some of the services the Olympic network was able to support included local viewing of replays using Intel’s True View technology, which gives fans the ability to watch a play or action from a 360-degree angle. While Intel has had limited deployments of the technology at some U.S. sporting events, for the Olympics Saw said they used hundreds of cameras linked over millimeter wave frequencies, which can offer very low latency.

“They needed [to have the images] in real time,” Saw said, and built the millimeter wave network to do just that. While the network “wasn’t fully compliant to the subsequent 5G standards, a lot of what they built is the forerunner to 5G,” Saw said. “It was a pretty cool showcase, and will certainly find a home in stadiums.”

No Millimeter Wave spectrum for Sprint

Millimeter wave networks, however, won’t be part of Sprint’s early push toward 5G, said Saw. Instead, he said Sprint will concentrate on deploying “Massive MIMO” networks in its rich space of spectrum at the 2.5 GHz frequency, where Sprint controls upwards of 150 MHz of spectrum in most major U.S. metro markets.

Without trying too hard here to explain exactly how Massive MIMO works — think splitting up transmissions between mulitple antennas then using lots of compute power to bring the data back together — the key here is Sprint’s spectrum holdings, which Saw said are still only about half used.

“When we launched LTE [on the 2.5 Ghz spectrum] we used less than half the spectrum we had,” Saw said. “With 5G, we will use all the spectrum we have in market. We’ll be one of very few carriers who launch 5G in the same [spectrum] footprint [as LTE].”

With the ability to carry “four to 10 times the capacity of regular LTE,” Saw sees Massive MIMO 5G as something perfect for large public venues like stadiums and shopping malls.

“When you have sports events with 50,000 people in the stadium, you need this kind of capacity,” Saw said. “Were building out the footprint for [5G] this year, and we’ll launch next year.”

Saw said that part of the infrastructure support for 5G networks will be different as well.

“It’s more than just speed, or more capacity. It’s more than tonnage,” Saw said. “We’ll have a different way of deploying the new network, with a more distributed core, one [with more resources] out to the edge of the network.”

Why is such equipment redistribution necessary? According to Saw, a network with more components at the edge can help with content delivery for the new bandwidth-hungry apps like virtual-reality replays.

“Say you want VR at a hockey game, where you want to give real time [replay] viewing to customers, with different camera angles,” Saw said. “You literally have to have the 5G core inside the stadiums, so it can process [the content] without having to go back to the cloud.”

Will DAS trail in the path to 5G?

One type of network Saw doesn’t see leading the way to 5G is the traditional DAS, or distributed antenna system.

“DAS is going to have to migrate to 5G,” Saw said. “It’s not going to lead the pack.”

In fact, Saw said Sprint has been somewhat of a reluctant DAS participant at times, including at the most recent Super Bowls. In the last two of the NFL’s “big game” events, Super Bowl 51 in Houston and Super Bowl 52 in Minneapolis, Saw said Sprint used small cell deployments instead of the neutral DAS systems to augment its coverage.

“We had hundreds of small cells, inside and outside [the venues],” Saw said. “We got the same performance, maybe better, for a lot less money.”

Part of the issue for Sprint and DAS, Saw said, is that the carrier usually has to pay more for its unique spectrum bands, especially the 2.5 GHz frequencies which are not used by any of the other major wireless carriers.

“We always think through before we sign up for DAS fees… there’s more than one way to skin a cat,” Saw said. While in many cases there is no alternative except to participate in a neutral-host configuration, Saw said “we do prefer small cells.”

Will CBRS help?

One of the more hyped platforms being pushed this year is use of the CBRS spectrum at the 3.5 GHz range for not just more carrier networks, but even for “private” LTE networks, like for venues or campuses.

“It’s an interesting concept because it opens things up to more than just four operators,” Saw said. But he also called out the need for an online database to make sure CBRS spectrum use doesn’t interfere with systems run by the U.S. Navy, and added that without any definitive FCC action yet, the rules for future CBRS use are still unclear.

“There’s quite a lot of work to be done, and not a lot of spectrum there,” said Saw. While claiming that Sprint is “watching CBRS with interest,” he added that with its 2.5 GHz holdings, Sprint most likely won’t be at the front of any CBRS deployments.

“At the end of the day, CBRS is not 5G,” Saw said.

How will a merger with T-Mobile help?

Since our conversation took place just a day after Sprint and T-Mobile announced their renewed plans to merge, Saw didn’t have a lot of details to share, beyond his opinion that the two companies’ different spectrum holdings would build a more powerful competitor when put together.

“When you put our 2.5 (GHz) with their 600 MHz it gives you a much larger footprint with higer capacity,” Saw said. “There’s tremendous synergy. Both [companies] are enthusiastic about this deal.”

New Report: DAS deployments rule, with new networks at Wrigley Field, AT&T Park and Amalie Arena

Call it the ‘Connect the DAS’ issue — our latest STADIUM TECH REPORT is heavy on DAS news, with new deployments at Wrigley Field, AT&T Park, and Amalie Arena — all of them breaking news, as in you heard it here first!

At AT&T Park, the home of the San Francisco Giants, there is a brand new upgrade to the stadium’s DAS network, an AT&T-only deployment of DAS antennas inside the same under-seat enclosures used for stadium Wi-Fi. An experiment at first, just a few months into the season it has surprised both the team and the carrier with how well it’s doing. Get the details by DOWNLOADING OUR FREE REPORT right now!

Second at bat in the news-scoop arena is another DAS deployment, this one just getting underway at Amalie Arena in Tampa, home of the NHL’s Lightning. The twist on this new network — also being installed by AT&T — is that it will exclusively use MatSing ball antennas, those quirky-looking “big ball” antennas that you may have seen used in a temporary fashion at outdoor events. What’s bringing them inside? DOWNLOAD THE REPORT and read our exclusive story!

And at venerable Wrigley Field — the friendly confines of the Chicago Cubs — a long-planned upgrade to the venue’s cellular systems is finally in place, using JMA Wireless equipment deployed by DAS Group Professionals. Our in-person visit took a look at how DGP and the Cubs merged new technology with one of baseball’s most historic structures. Who says DAS is dead?

In addition to those stories we also have a complete, in-person visit and profile of the new networks at the newest stadium in MLS, the Los Angeles Football Club’s Banc of California Stadium. We also have a Q&A with Sprint CTO Dr. John Saw, all packed into one issue ready for FREE DOWNLOAD right now!
