Part 2 of this story picks up with the decision to put Wi-Fi APs under seats at Levi’s Stadium. If you missed it, here is the link to Part 1.

According to Chuck Lukaszewski, now vice president of wireless strategy and standards at Hewlett Packard Enterprise (formerly very high density architect in the CTO Office of Aruba Networks), Aruba had been testing under-seat AP designs since around 2010, “in one form or another.” There were some initial tests of under-seat AP deployments at Turner Field in Atlanta and at American Airlines Arena in Dallas, but nothing on the scale of AT&T Park’s 2013 deployment, or on the scale Aruba planned to have at Levi’s Stadium when it opened in 2014.

Some of the first under-seat Wi-Fi deployments in other arenas were actually deployed completely under the stands, Lukaszewski said, with signals shooting up through the concrete. Though he said “you could get reasonably good throughput through concrete,” especially for 2.4 GHz frequencies, installing antennas above the concrete was “considerably better,” Lukaszewski said.

Curiously, one of the biggest problems in stadium Wi-Fi deployment — especially for those heavy on overhead antenna use — is negotiating interference between antennas; sometimes, clients can “see” antennas and APs that are across the stadium, and will try to connect to those instead of the AP closest to them, a problem that leads to inefficient bandwidth use. Interference also means you can’t place APs too closely together, making it somewhat of an art to find ways to increase coverage without increasing interference.

What Aruba found in its testing, Lukaszewski said, was that under-seat Wi-Fi AP deployments could be far more dense than overhead-centric designs, mainly because the human bodies in the seats would provide beneficial “blocking” of signals, allowing network designers to place APs more closely together, and to be able to re-use the same Wi-Fi channels in more antennas.

“If you can use human bodies to contain signals, you can have much smaller cells,” Lukaszewski said. Under-seat deployments, he said, “allows us to re-use the same channel less than 100 yards away.”

With more channels available for each AP, the difference in the metric Lukaszewski calls “megabytes per fan” can be “profound” for an under-seat design versus an overhead design, he said.

“We do see trends [in stadium network data] of under-seat being able to deliver well over 100 MB per fan per event, while overhead designs [deliver] significantly under 100 MB per fan per event,” said Lukaszewski.

Dan Williams, the former vice president of technology for the San Francisco 49ers, said he and Lukaszewski were in agreement that under-seat was the best method to deploy at Levi’s Stadium.

“I just did not believe in overhead,” said Williams, who said he brainstormed with Aruba’s Lukaszewski on the under-seat idea, which they both brought to the Wi-Fi design at Levi’s. By using under-seat APs, Williams said, the Levi’s Stadium design looked to provide “cones [of bandwidth] around the audience, immersing [fans] in a signal.”

After beating the previous year’s Super Bowl Wi-Fi total at its NFL regular-season opener in 2014, Levi’s Stadium’s Wi-Fi network more than passed its biggest test ever this year, carrying a record 10.1 terabytes of Wi-Fi data during Super Bowl 50. Those numbers are proof of Lukaszewski’s claim: “By far, under seat is better.”

New deployments trending to under-seat

Even though under-seat deployments can be considerably more expensive, especially in a retrofit situation where deployment requires coring through concrete, many stadiums are now seeming to agree with another Lukaszewski claim, that “the return absolutely justifies the investment.”

At AT&T Stadium in Arlington, Texas, the Cowboys quicked followed their sister park’s lead and installed under-seat APs in force ahead of that venue’s hosting of the inaugural College Football Playoff championship game in January of 2015. John Winborn, chief information officer for the Dallas Cowboys Football Club, said the team worked with AT&T’s “Foundry” innovation centers to produce a smaller, sleeker under-seat AP enclosure that fit well with the stadium’s commitment to aesthetics.

Back on the baseball side, the Giants now have 1,628 Wi-Fi APs in their park, with the vast majority of them under-seat, in all three decks of seating. And the Giants’ main rival to the south, the Los Angeles Dodgers, also used under-seat APs in a recent Wi-Fi upgrade.

And if Levi’s Stadium led the way for under-seat Wi-Fi, the new mainly under-seat network at the refurbished Kyle Field at Texas A&M might be the QED on the debate, with ultra-fast network speeds and big data-consumption numbers (including 5.7 TB of Wi-Fi at a game versus Alabama) adding measureable momentum to the under-seat trend. Bill Anderson, CEO of Wi-Fi deployment strategy firm AmpThink, said he was an early disbeliever in under-seat Wi-Fi — until he saw the numbers.

“At first we mocked it, made fun of it,” said Anderson, whose firm has been called in to produce Wi-Fi network designs for several recent Super Bowls, as well as for the Kyle Field design. But when Aruba showed AmpThink the data from under-seat tests and deployments, “that was the ‘a-ha’ moment for us,” Anderson said.

Working with Aruba at Kyle Field, AmpThink was able to collect its own data, which convinced Anderson that under-seat was the way to go if you wanted dense, high-performing networks.

“The really important thing is to get APs closer to the people,” said Anderson. “That’s the future.”

Anderson said some doubters may remain, especially those who try to mix a small amount of under-seat APs with existing overhead deployments, a recipe for lowered success due to the potential interference issues. At Texas A&M, Anderson said AmpThink was able to build a design with far less interference and much greater density than an overhead solution, producing numbers that people have to pay attention to.

“We only know what we’ve observed, but we’re evangelistic supporters” of under-seat designs, Anderson said. “If someone says to you under-seat is hocus-pocus, they’re not looking at the data.”

Not for everyone, but more are trying under-seat

Though proponents of under-seat Wi-Fi all agree on its ability to deliver denser, faster networks, they all also agree that under-seat can be considerably more costly than overhead Wi-Fi, especially in a retrofit situation.

In addition to having to core through concrete seating areas to get conduit to the under-seat APs, the devices themselves need to be sealed, to guard them from weather, drink spills, and the power-washing equipment employed by most stadiums to clean seating areas.

Aruba’s Lukaszewski also noted that under-seat deployments generally use more linear feet of cabling to connect the APs than overhead, which also drives up the cost. Then since under-seat designs tend to use more APs, that also means a higher budget to cover a higher number of devices.

For some stadiums, the construction materials used prohibit the under-seat option from even being tried. At the Green Bay Packers’ legendary Lambeau Field, a late-1950s construction design that used lots of concrete and rebar — as well as part of the stadium’s bottom sitting directly in the ground — meant that under-seat Wi-Fi wasn’t an option, according to Wayne Wichlacz, director of information technology for the Packers.

Other stadiums, like the University of Nebraska’s Memorial Stadium, don’t have enough space between the stadium’s bleacher seats and the floor for under-seat APs to be safely installed. And many schools or teams simply don’t have big IT budgets like the $20-million-plus available to Texas A&M that allowed the Kyle Field design to seek the best result possible.

But many of the new stadiums under construction, as well as existing venues that are planning for new best-of-breed networks, have already committed to under-seat Wi-Fi designs, including the Sacramento Kings’ Golden 1 Center, where Ruckus Wireless will implement its first under-seat stadium Wi-Fi network.

Steve Martin, senior vice president and general manager at Ruckus, said the Golden 1 Center design, planned to be the most dense anywhere, will “primarily be underseat,” a choice he said “helps in a lot of ways.”

Foremost is the performance, something Martin said Ruckus has been testing at the Kings’ current home, the Sleep Train Arena. “It [under seat] does give you the isolation for frequency re-use,” he said.

The under-seat design also makes sense in Golden 1 Center since the stadium’s overall design is very open, with lots of glass walls and unobstructed views.

And under-seat deployment is even making inroads into the distributed antenna system (DAS) world, with Verizon Wireless implementing more than 50 under-seat DAS antennas at Levi’s Stadium prior to Super Bowl 50. Mainly installed to cover the bottom-of-the-bowl rows, the under-seat APs helped Verizon manage a record day for DAS traffic, with 7 TB reported on its in-stadium cellular network during the game.

“To get a quality signal, we had to go under seat,” said Brian Mecum, vice president, network, for Verizon Wireless, who said that in that area of the stadium, under seat was the only way to get a quality signal close to the subscriber’s phone. Verizon, he said, helped design the under-seat DAS antenna, and is looking to deploy it in other stadiums soon.

“It’s the first of more,” he said.

University of Wisconsin takes on Wi-Fi, Badger Game Day app upgrades

Sports fans at the University of Wisconsin have been enjoying a nice technology two-fer for the last 20 months: In addition to new Wi-Fi and beacon technology at its largest sporting venues in Madison, Wisc., the university also released v3.0.2 of its Badger Game Day app which adds live and archived video, among other features, for fans and their smartphones.

Jim Roberts, director of technical services for the university’s athletic department, described this as a happy coincidence as opposed to a larger strategy to bring sports technology to the Badger faithful. “Knowing that the new Wi-Fi system was coming, the group working on the app upgrade was able to incorporate more features, knowing fans could take advantage of the improved Wi-Fi and not rely solely on cellular data plans,” Roberts said.

Editor’s note: This profile is an excerpt from our latest STADIUM TECHNOLOGY REPORT, which is available for FREE DOWNLOAD from our site. In addition to this stadium tech deployment profiles we also take an in-depth look at the new trend of deploying Wi-Fi and DAS antennas under seats, and provide a wireless recap from Super Bowl 50. GET YOUR COPY today!

The Wisconsin venues are Camp Randall, a bowl-style football stadium with a capacity of 80,321; and nearby Kohl Center, used for hockey, basketball, concerts and other live events with room for 17,230. The LeBahn Arena, built for women’s ice hockey with a capacity of 2,273, is also included. In part because of their proximity, Roberts and his team used the upgrades to replace and enhance the underlying infrastructure for the venues – core switching, Wi-Fi access points, an IPTV system, cabling, electrical power and HVAC improvements — $11 million for the whole package, according to Roberts.

“Due to the expected size of the population connecting to Wi-Fi, we had to upgrade the entire network,” he explained, adding that the previous 10/100 Mbps backbone with Gigabit Ethernet uplinks and its 32,000 MAC address capacity was insufficient for the job.

“We upgraded our core to some pretty big Cisco routers at each venue that could handle 128,000 MAC addresses, with 10-gigabit fiber to all 33 telecom rooms within the Camp Randall complex,” he said; they also added about 1,100 wireless APs. Camp Randall got upgraded during the summer of 2014; the Kohl Center and LeBahn were done a year later.

Camp Randall proved to be the largest test, both from an engineering and design perspective. Built in 1917, its open bowl lacks the overhangs from which RF engineers love to hang antennas and other infrastructure.

“The east side of the bowl became our biggest challenge with getting the signal to penetrate deep enough into the sections,” Roberts said, adding that the problem was especially acute for seats closest to the field, where the first few rows are tarped over. Initially, APs were installed below the tarps, but the signal only carried 10 rows back.

“We ended up mounting the APs on the front, 4-6 feet up from ground level,” and above the tarps, he explained. “They don’t affect the sight lines for spectators. But getting the APs to shoulder height from waist height definitely helped us get it back to row 25.”

APs were also mounted just above the entry tunnels, where the hardware and antenna could be attached to railings and concrete. Cisco is the University of Wisconsin’s AP vendor; the deployment uses Cisco model 3700s.

Roberts and his team also ran into some structural issues with waterproofing and cabling that kept them from putting in more APs in the student section. They had to re-calculate where the APs would go; consequently, coverage can be spotty in the student section, which is exacerbated by the high density of phones in that part of the stadium. AT&T and Verizon both have DAS infrastructure in Camp Randall that helps coverage, but Roberts and his team are looking at long-term solutions for Wi-Fi coverage in that section and throughout Camp Randall.

The University of Wisconsin worked closely with AmpThink on a facility-wide Wi-Fi analysis, according to Bob Lahey, a network engineer in the athletic department. AmpThink did the design and tuning and worked out some issues in advance. “Our facilities staff and [AmpThink] discussed locations for best coverage and worked through the aesthetics before we started the project,” Lahey said. AmpThink was also onsite during the first year to see how the Wi-Fi performed with people in the bowl. “You can only figure out so much without people there,” Lahey laughed.

Getting Online at Camp Randall

The stadium’s fan-facing wireless network, Badger WiFi, is a captive portal that asks users for their name, email address and zip code. There are also two boxes: one, users must check to agree to terms and conditions of service; the second allows the university to send them emails, and by default, the second box is checked. “Our plan is to send them email surveys and allow them to remain on the system and not have to re-authenticate every time they come to one of our buildings,” Lahey said. “But if they uncheck, they have to re-authenticate.”

The university does no bandwidth limiting or throttling back usage once users are logged in. “We’ve got dual 10-gigabit links and 100-gigabit to the world, so we’re not too concerned about overall bandwidth,” Lahey said. “We limit each radio in the AP to a maximum of 200 clients. It doesn’t happen often, but we see it occasionally.” Camp Randall users normally get at least 1 Mbps bandwidth — plenty for checking scores or posting to social media, Lahey added. Kohl Center users average 40-60 Mbps because the venue is less dense.

At present, 65-70 percent of Badger Wi-Fi clients are on 5 GHz spectrum rather than 2.4 GHz. Roberts finds the 5 GHz band easier to manage, and said users get a better experience. “If we have problems with wireless, it is most times an older couple with their iPhone 4,” Roberts said. “APs can only do so much, but sometimes a phone [using 2.4 GHz spectrum] will want to connect with an AP a half mile across the field rather than one that’s 10 feet away.”

He also said the maximum number of unique clients for Camp Randall is about 26,000, or 37 percent of the crowd. “We assume that’s going to keep growing and we’ll have to augment the system,” he said. “At some point we won’t have enough access points.”

Game Day Gets a Badger Refresh

Concurrently, the Badger Game Day smartphone app was getting new features like live video replay and interaction with Bluetooth-based beacon technology. The app’s first iteration was initially for football, then expanded to all 10 sports that sell tickets; the latest version embraces all 23 sports at the University of Wisconsin, men’s and women’s. “Not many schools have all their sports represented, so while the traffic may not be high on rowing, it’s a great recruitment tool,” said Ben Fraser, director of external engagement for the athletics department. “So it helps there with the coaches sending out links or for parents and other supporters.”

It also helps with fans. “Collegiate and professional sports venues are looking for how to keep fans entertained and also allow them to participate in the game via social media and other methods,” noted Tam Flarup, director of the athletic department’s website services. When there’s break in the action, Badger fans are busy posting to Facebook, Instagram and of course, Wisconsin’s infamous Jump Around. “Twitter’s also allowing Periscope live video in its tweets now,” Flarup added. “Our fans will like that – it keeps them in the stands with a great game day atmosphere and experience.”

The university developed the first two iterations of Badger Game Day internally but chose to outsource the upgrade to sports-app developer YinzCam in June 2015 and gave them a tight deadline to meet — Aug. 30, just in time for Badger football season. YinzCam delivered on time, and then met an Oct. 15 deadline for revisions and tweaks, Fraser said.

Badger Game Day now includes live video replay from four different camera angles; YinzCam’s secret sauce makes streaming video across Wi-Fi more efficient. “Video would have been impossible without the Wi-Fi investment we made,” Fraser said.

Unlike previous iterations that only allowed the participation of a single sponsor, the new Badger Game Day app gives the university the ability to sell individual pages and sports, Fraser said.

Perhaps the leading edge of Badger Game Day is its use of Bluetooth-based beacon technology and messaging with geo-fencing. Gimbal Inc. worked with the university customize the technology; Fraser and his team did some social media messaging to alert fans to the feature and to remind them to turn it on.

The first remote use of messaging with beacons and geo-fencing was in Dallas for Wisconsin’s season opener in Dallas at AT&T Stadium; the feature was then used continually at both Camp Randall and the Kohl Center.

“We continued to use this messaging on the road for the Holiday Bowl in San Diego,” Fraser said. “Messages varied from welcome messages that were linked to videos from our players, to informational messages that informed fans about events, to scavenger hunts that engaged our fans at these sites.”

When users first download the app, there’s a proximity allowance message that they must activate to receive beacon messages. So far, the university has sent out 46 unique messages, 21 of which were geo-fenced. At each home game, they geo-fence Camp Randall with a welcome video from players; they reached an average number of 1,160 fans per game with these welcome messages and videos.

“We’re still learning how fans are using [beacons and Bluetooth], and we’re trying not to hit them with too many ads,” Fraser said. By building their trust, it encourages fans to leave their Bluetooth on for the signal to find them. “And we are looking for ways to improve it,” he added. Potential future additions: Features that show the length of lines at concession stands and restrooms, and an online lost and found. They’re also looking for more robust scheduling information inside the app — such as which broadcast network is carrying the game, along with links to Wisconsin’s video stream and live stats.

App development and a new server cost the university about $100,000, according to Fraser and Flarup. Since August 2015, there have been 123,000 downloads of Badger Game Day and nearly 1 million page views. Average time spent per game on the audio feature of the app is about 14 minutes. There’s more room to grow as fans continue to download and use the app; there’s plenty of revenue upside as well as sponsors discover multiple avenues for their messaging and content.

In addition to ticket sales and hotel revenues, you can count on an NCAA basketball tournament crowd to bring wireless demands to host stadiums these days. To prepare for the expected crush, wireless carriers, third-party integrators and venues themselves have bolstered both DAS and Wi-Fi networks, especially at NRG Stadium in Houston, site of the men’s Final Four April 2 and 4.

NRG Stadium, also home to the NFL’s Houston Texans, is slated to host Super Bowl LI next Feburary, and as such will be getting a new Wi-Fi network built by 5 Bars with gear from Extreme Networks ahead of the biggest big game. Unfortunately for data-hungry hoops fans, construction on that network won’t start until after the Final Four, meaning it will be cellular-only for the fans and followers at the championship weekend games.

But connections for customers of major carriers should be fine, since AT&T has already spent $25 million on Houston-area DAS upgrades, including at the stadium itself as well as at the convention center and other areas hosting Final Four activities. There will also be a portable Cell on Wheels, or COW, outside the convention center, where AT&T’s ball-shaped directional antennas will be bringing extra capacity to the scene.

Verizon said that it has already spent $40 million on improving its cellular infrastructure in and around NRG Stadium; inside the venue Verizon said its updated DAS deployment has 783 antennas, able to handle four times the capacity of the previous infrastructure. Outside the stadium Verizon said it has implemented an outdoor DAS to cover parking lots and tailgating areas. Verizon said it is also targeting downtown areas and the Houston airport for improvements ahead of Super Bowl LI.

At some of the regional tourney sites, third-party neutral host ExteNet Systems has been busy as well, adding capacity to some of its stadium DAS deployments as well as to one Wi-Fi network it runs at the Dunkin’ Donuts Center in Providence, R.I. At the Wells Fargo Arena in Des Moines, Iowa, ExteNet recently added U.S. Cellular to its DAS deployment, the first venue in which U.S. Cellular has been an ExteNet customer. Other ExteNet deployments that will see men’s or women’s NCAA games this year include the Barclays Center in Brooklyn, N.Y.; Bankers Life Fieldhouse in Indianapolis; and the Webster Bank Arena in Bridgeport, Conn.

In Denver at the Pepsi Center, a new (but not yet publicly announced) Wi-Fi network using Avaya gear should get a good test if it is live for the regional games there this weekend. With all these and more, if any fans or venues want to send speedtests in or post-games stats, we’ll happily print them.

Commentary: Will stadium networks ever catch up with demand?

If there’s one thing the stadium-networking industry learned — or should have learned — from the stunning stats from Super Bowl 50, it’s that nobody really knows where or when the demand for in-venue bandwidth will stop growing.

Thanks to the smart folks who built the Levi’s Stadium Wi-Fi network — and the smart deployers and carrier partners who doubled down on the DAS this summer — the venue was able to handle an incredible 26 terabytes of wireless data on Super Sunday, with 15.9 TB amongst the four major cellular carriers on the DAS, and 10.1 TB on the stadium’s Wi-Fi network. Both were easily new records for single-day events, far eclipsing the totals seen at Super Bowl XLIX the year before.

The question, of course, for everyone else is: What comes next? And what does that mean for networks built in the past few years?

Keep building for growth

In some follow-up discussions with folks from Aruba, the Levi’s Stadium networking team, Verizon Wireless and others in the industry, I wondered out loud if what we are seeing is just yearly growth in demand, or whether expanded networks are merely satisfying pent-up demand that was always there.

To be sure, the “big” events like the Super Bowl, the World Series and the Final Four are always going to generate outsize traffic numbers, especially as more and more fans join the selfie craze and post photos and videos from the stadium, showing the rest of the world how great their life is. According to Verizon, the amount of traffic uploaded on their DAS network at Super Bowl 50 was double the upload traffic the carrier saw at Super Bowl XLIX, validating Verizon’s belief that traffic was going to grow significantly.

For mobile traffic in general, and for in-stadium wireless activity specifically, the continued growth over the past few years can likely be traced to a number of factors, including the ever-increasing power of mobile devices; the new number of bandwidth-hungry apps that incorporate images and video; and a steady increase in familiarity with devices and apps, as older folks — those more likely to purchase event tickets — catch up to their kids in wanting to use, and being able to use, the content-sharing features of social media and other communication apps. And, simply, more people trying and successfully connecting to in-stadium networks, reversing historical thinking that told them from experience in past years that connecting at a stadium was futile. In almost all venues these days, no longer is that the case.

So with no end yet in sight to the general doubling of traffic on a year to year basis, the big question out there for stadium technology teams has to be — is what we have now enough to handle growing needs, and if not, what are we going to do about it? The fact that cellular carriers (correctly) assumed they needed to add capacity to the Levi’s Stadium DAS a year after it was deployed should give pause to anyone building a network right now; though your venue may not be hosting the Super Bowl anytime soon, it might not hurt to re-think the traffic projections that have been made and step them up a bit, just in case.

On both the Wi-Fi side and the DAS side, we may also be looking soon at a need for new kinds of technology to help build the networks of the near future. In this issue we take an in-depth look at the trend toward putting antennas for both Wi-Fi and DAS under seats, mainly to build networks that are more dense and can handle more traffic.

Verizon, which pioneered DAS under-seat antennas at Levi’s Stadium this year, said it is already seeing stadiums where just adding another sector of traditional DAS produces diminishing returns; if traffic on both types of networks keeps growing at the current rate, when will existing designs become obsolete? And what will replace them?

Stadium network owners shouldn’t ignore policy

As stadium-networking types ponder the future, it would serve the industry well to start thinking together as well, especially in the areas of telecom policy and standards-setting. As the builders of telecom networks worldwide ponder the future of 5G technologies there are some discussions where stadium networking representatives are nowhere to be found, especially in the potentially troubling direction of LTE-U, the idea of carriers using unlicensed bands for LTE traffic.

It’s still early days in the LTE-U discussions, but a recent decision by the FCC to allow carriers to conduct tests of the technology should be a call to action for the stadium networking industry. While nobody knows quite for sure yet what will happen to an in-venue Wi-Fi network if and when LTE-U traffic appears, it seems to make sense for the industry to get together and at least present some kind of unified voice before decisions get made.

At the recent Silicon Flatirons telecom policy conference in Boulder, Colo., there were exactly zero representatives from the venue Wi-Fi ecosystem present, including no visible representation from the Wi-Fi and DAS gear manufacturers who sell into the stadium networking space. With telecom providers hungry for spectrum of any kind, it’s a fool’s bet to assume that the unlicensed bands used in stadiums worldwide today will remain as free and available as they are now. It’s just another factor that’s needed to be considered, as venue tech professionals plan for a future of ever-increasing needs.

UPDATE, 2/8/16, 1:50 p.m. — We now have data totals in from all four of the major U.S. cellular carriers, and at Sunday’s Super Bowl 50, fans combined to use 15.9 terabytes of data on the networks in and directly around Levi’s Stadium in Santa Clara, Calif.

Leading the way in usage was Verizon Wireless with a claim of 7 TB used by its customers; AT&T was next with 5.2 TB of claimed usage, followed by T-Mobile with a report of 2.1 TB, and Sprint with 1.6 TB. All the carriers’ numbers are well above figures from last year’s Super Bowl, where by our reporting Sprint, AT&T and Verizon had a combined 6.56 TB of cellular data consumed during the big game. (We did not have any T-Mobile reports from last year.)

For all the carriers, the data apparently includes both traffic on the in-stadium distributed antenna system (DAS) network was well as any macro deployments outside the stadium in parking lot areas. The final total was well over double the 6.56 TB of cellular traffic seen at last year’s big game in Glendale, Ariz. We are still waiting for Wi-Fi numbers from the Levi’s Stadium networking crew but it’s a good bet the 6.23 TB number from last year’s game will be eclipsed and we will have a new single-game Wi-Fi record as well so stay tuned.

Though we did hear and see some scattered reports of network connectivity issues during the Denver Broncos’ 24-10 victory over the Carolina Panthers it appears the upgrade of the DAS Group Professionals DAS install at Levi’s Stadium with its gear mainly provided by JMA Wireless stood up to the biggest-ever test of traffic. Congrats to all involved.

Thanks also to the Verizon and AT&T crews who supplied us with tweet reports and emails Sunday night, it made for some entertaining in-game stats. Some tweets embedded below.
