THE MSR TOP 10 FOR WI-FI

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.

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.

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.

‘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.

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.”
