Everest going solo in Wi-Fi equipment market

Once a very tightly coupled part of electronics giant Panasonic, Everest Networks is now going solo in its pursuit of market share in the competitive arena for sports stadium and large public venue Wi-Fi deployments.

Though Everest representatives claimed that business is normal and usual, the emergence of Everest as a standalone company is a recent thing, even according to news clips posted on the company website. There, reports of some recent customer wins and news accounts of a high-traffic showing at an Everest-powered network at the Philadelphia Eagles’ Lincoln Financial Field all refer to the equipment as being from Panasonic, or as “The Everest Network Solution by Panasonic,” as a Panasonic press release describes it.

Apparently a recent reorganization at Panasonic caused the change in the marketing structure around the Everest product line; the products themselves have drawn interest in the stadium Wi-Fi market for their advertised ability to provide wider and deeper coverage patterns than other existing products.

Though Everest COO Simon Wright said in a phone interview Friday that “nothing has changed from a product perspective” and that the relationship between Panasonic and the Everest product is “exactly the same,” according to several sources the internal reorganization has eliminated multiple jobs inside Panasonic related to Everest, and caused the formation of the standalone Everest entity, which according to Wright’s own LinkedIn profile happened just last month. According to Wright, the headquarters office is in Santa Clara, Calif., is “within sight” of the San Francisco 49ers’ Levi’s Stadium.

New models, new deals?

While the explanation about the change of business direction from the Panasonic side will have to wait — Panasonic has not yet replied to our inquiries — according to Wright the Everest business is looking good, with new models coming out as well as some new (yet unannounced) customer wins in the near-term pipeline. According to Wright one of the new products is a Wi-Fi AP that can send a signal 300 feet, an attractive option for stadiums and venues with high overhangs that need to reach distant seats. One of the advantages touted by Panasonic and now Everest is that its APs include multiple radios, reducing the amount of actual hardware that venues may need to deploy.

However, no Everest stadium customers have as of yet agreed to allow any up-close testing or provided any detailed season-long performance metrics. While team officials at the Philadelphia Eagles have provided praise for the Everest gear in press releases, they have not yet answered requests for live interviews. John Spade, CTO for the NHL’s Florida Panthers and BB&T Center in Sunrise, Fla., has tweeted favorably about a Panasonic/Everest deployment at the arena whose networks he oversees, and said in subsequent messages that he hopes the equipment line will continue.

According to Wright, the path ahead for Everest is a typical one for a startup, with hiring and funding tasks part of the mix. While he would not provide a total of funding that Everest has to operate, or how many members it has on its team, he did say that Panasonic remains a major investor and will continue to resell and promote the product line.

“They [Panasonic] just secured a major contract for us,” Wright claimed. “They will continue to be an important partner for us.”

Average per-fan Wi-Fi use total jumps again at Super Bowl 52

After a year where the actual amount of average Wi-Fi data used per connected fan at the Super Bowl dropped, the trend of more data used per fan reversed itself again to a new peak at Super Bowl 52, with an average total of 407.4 megabytes per user.

Even though the number of unique connections to the Wi-Fi network at U.S. Bank Stadium for Super Bowl 52 also increased to a record 40,033 users (according to the official statistics compiled by Extreme Networks), the jump from 11.8 terabytes of Wi-Fi data used at Super Bowl 51 to 16.31 TB used at Super Bowl 52 pushed the average per-user number to the top, surpassing the 333 MB per user number from Super Bowl 51, as well as the 370 MB per user mark seen at Super Bowl 50.

While this statistic has not ever been called out by the Extreme Networks Super Bowl compilations, we here at MSR think it is a vital mark since it shows that even with more users on the network those connected users are still using more data. That means that IT departments at venues everywhere should probably still plan for no letup in the overall continued growth in demand for bandwidth at large-venue events, especially at “bucket list” events like the Super Bowl.

Last year we guessed the drop in per-user totals from Super Bowl 50 to Super Bowl 51 might have been due to a larger number of autoconnected users, but we never got an answer from the Extreme Networks team when we asked that question. At U.S. Bank Stadium there was also an autoconnect feature to the Wi-Fi for Verizon Wireless customers, but it didn’t seem to affect the per-user total mark.

Minneapolis airport sees 6 TB of Wi-Fi traffic day after Super Bowl

February 20, 2018 by

A day after Super Bowl 52 at U.S. Bank Stadium in Minneapolis set new records for wireless data consumption, the Minneapolis-St. Paul International airport had a big wireless day of its own, with 6 terabytes of traffic used on the airport’s Wi-Fi network and another 6.5 TB on the Verizon cellular network.

Eduardo Valencia, vice president and chief information officer for the Metropolitan Airports Commission, said the Wi-Fi data used on Feb. 5 was “close to double typical data consumption” on the free-access network provided by Boingo Wireless, even though the airport saw a fairly normal range of users connecting.

“There was no spike in [the number] of users, but the users who did connect consumed twice as much data, with downloads about 3 times normal,” Valencia said. The Monday-departure crowd, he said, saw about 31,000 unique users connect to the Wi-Fi network, which Valencia said “is at the top of the normal user range” the airport network usually sees. Valencia said that during the week leading up to the big game on Feb. 4, the airport Wi-Fi saw between 23,000 and 31,000 daily connections.

Boingo, which has been powering the Wi-Fi at Minneapolis-St. Paul International Airport (aka MSP) since 2012, updated and expanded coverage a year ago, according to Valencia. Though Boingo would not provide details on how many new APs were added or how many the network has now, Valencia said coverage was increased in many areas, like the tunnels between terminals, to make sure visitors didn’t lose connectivity.

The cellular infrastructure at the airport also got an upgrade before the Super Bowl, with a neutral host distributed antenna system (DAS) deployed by Verizon Wireless. The DAS, which uses Corning ONE fiber equipment on the back end, provided coverage for all the top wireless carriers, Valencia said. Though it was cut close — the final pieces went live on Jan. 19, according to Valencia — the expanded DAS, which added antennas all over the terminals as well as outside covering runways, also performed well, according to Valencia.

Though only Verizon stats were available, Valencia said Verizon saw an average of 2.8 TB of data per day in an 11-day span around the Super Bowl, with 6.5 TB of traffic seen on Monday, Feb. 5. Like the Wi-Fi traffic, Valencia said Verizon’s day-after total was about double the average daily consumption.

While there is extra pressure to perform ahead of the NFL’s big game — “The NFL told us the Super Bowl experience begins and ends at the airport,” Valencia said — the payoff will stay for years, as all the new network gear added in advance is permanent.

“We swallowed hard for 9 days, but the success was the culmination of a lot of planning,” Valencia said. “Now the good thing is, everything [in the network] is here to stay.”

Fans use 16.31 TB of Wi-Fi data during Super Bowl 52 at U.S. Bank Stadium

February 9, 2018 by

It is now official — we have a new record for most Wi-Fi data used at a single-day event, as fans at U.S. Bank Stadium in Minneapolis for Super Bowl 52 used 16.31 terabytes of data on the Wi-Fi network.

According to statistics compiled by Extreme Networks during the Philadelphia Eagles’ thrilling 41-33 victory over the New England Patriots Sunday night, the AmpThink-designed network which uses Cisco Wi-Fi gear also saw 40,033 unique users — 59 percent of the 67,612 in attendance — a new top percentage total for any single-game network experience we’ve been told about. (The Dallas Cowboys saw approximately 46,700 unique Wi-Fi users during a playoff game last season, about 50 percent of attendance at AT&T Stadium.)

The network also saw a peak concurrent connection of 25,670 users, and a peak data transfer rate of 7.867 Gbps, according to the numbers released by Extreme. Though Extreme gear was not used in the operation of the network, Extreme has a partnership deal with the NFL under which it provides the “official” network analytics reports from the Super Bowl.

The final total of 16.31 TB easily puts Super Bowl 52 ahead of the last two Super Bowls when it comes to Wi-Fi data use. Last year at NRG Stadium in Houston, there was 11.8 TB of Wi-Fi use recorded, and at Super Bowl 50 in 2016 there was 10.1 TB of Wi-Fi data used at Levi’s Stadium in Santa Clara, Calif. So in reverse chronological order, the last three Super Bowls are the top three Wi-Fi events, indicating that data demand growth at the NFL’s biggest game shows no sign of slowing down. Combined with the 50.2 TB of cellular data used in and around the stadium on game day, Super Bowl 52 saw a total of 66.51 TB of wireless traffic Sunday in Minneapolis.

Super Bowl 52 represented perhaps a leap of faith, in that the handrail-enclosure Wi-Fi design had not yet seen a stress test like that found at the NFL’s biggest event. Now looking ahead to hosting the 2019 Men’s NCAA Basketball Final Four, David Kingsbury, director of IT for U.S. Bank Stadium, can be forgiven for wanting to take a bit of a victory lap before we set our Wi-Fi sights on Atlanta’s Mercedes-Benz Stadium, home of Super Bowl 53.

“AmpThink, CenturyLink and Cisco designed and built a world-class wireless system for U.S. Bank Stadium that handled record-setting traffic for Super Bowl LII,’ Kingsbury said. “AmpThink president Bill Anderson and his team of amazing engineers were a pleasure to work with and the experts at Cisco Sports and Entertainment supported us throughout the multi-year planning process required for an event of this magnitude. High-density wireless networking is such a challenging issue to manage, but I am very happy with our results and wish the team in Atlanta the best next year. The bar has been raised.”

Eagles see 8.76 TB of Wi-Fi data for NFC Championship game on new Panasonic network

January 29, 2018 by

The Philadelphia Eagles saw 8.76 terabytes of Wi-Fi data used at Lincoln Financial Field on Jan. 21 during the Eagles’ 38-7 win over the Minnesota Vikings in the NFC Championship game, a new high in one-day Wi-Fi usage for reported marks in games not called the Super Bowl.

Though the game’s position as No. 3 on our unofficial “top Wi-Fi” list (see below) may change as we get reports from other recent NFL playoff games, the mark is nevertheless impressive, and perhaps a big confirmation metric for Panasonic’s nascent big-venue Wi-Fi business. According to Panasonic, its 654-Access Point network inside “The Linc” also saw 35,760 unique connections during the game, out of 69,596 in attendance; the network also saw a peak of 29,201 concurrent devices connected (which happened during the post-game trophy presentation), and saw peak throughput of 5.5 Gbps.

What’s most interesting about the new Panasonic network in Philadelphia is that it is a completely top-down deployment, meaning that most of the APs (especially the 200 used in the seating bowl) shoot signals down toward seats from above. While most new networks at football-sized stadiums (and some smaller arenas) have turned to under-seat or railing-mounted APs to increase network density in seating areas, Panasonic claims its new “Everest” Wi-Fi gear has antennas that can provide signals up to 165 feet away, with “electronically reconfigurable directional beam profiles” that allow for specific tuning of where the Wi-Fi signal can point to.

By also putting four separate Wi-Fi radios into each access point, Panasonic also claims it can save teams and venues money and time on Wi-Fi deployments, since fewer actual devices are needed. By comparison, other big, new network deployments like Notre Dame’s often have a thousand or more APs; Notre Dame, which uses railing-mounted APs in the seating bowl, has 685 in the seating bowl out of a total 1,096 APs. Many of the Notre Dame APs are Cisco 3800 devices, which have two Wi-Fi radios in each AP.

Atlanta’s new Mercedes-Benz Stadium, which uses Aruba Wi-Fi gear mainly deployed under seats in the bowl, has nearly 1,800 APs, with 1,000 of those in the seating bowl.

Antennas close to fans vs. farther away

From a design and performance standpoint, the under-seat or railing-mounted “proximate” networks are built with many APs close together, with the idea that fans’ bodies will intentionally soak up some of the Wi-Fi signal, a fact that network designers use to their advantage to help eliminate interference between radios. The under-seat AP design, believed to be first widely used by AT&T Park in San Francisco and then at a larger scale at Levi’s Stadium in Santa Clara, Calif., was developed to help bring better signals to seats where overhang-mounted APs couldn’t deliver strong connectivity. Older concrete-bowl stadiums like Notre Dame’s also went with a proximate railing design for a similar lack of overhangs.

Though the Eagles’ IT team has repeatedly turned down interview requests from MSR since this summer, Danny Abelson, vice president connectivity for Panasonic Enterprise Solution Company, met with MSR last week to provide details of the deployment. Citing new, patented antenna technology developed specifically by Panasonic to solve the limitations of prior overhead gear, Abelson claims Panasonic can deliver a similar stadium experience for “two-thirds the cost” of an under-seat or railing-mount network design, with savings realized both in construction costs (since it is usually cheaper to install overhead-mounted equipment than under-seat or railing mounts due to drilling needed) and in the need for fewer actual APs, since Panasonic has four radios in its main Wi-Fi APs.

Abelson, however, declined to provide the exact cost of the Panasonic network at Lincoln Financial Field, citing non-disclosure agreements. There are also more questions to be answered about a Panasonic deployment’s cost, including charges for management software and/or administration services. Currently, Abelson said, Panasonic includes the costs for management software and management personnel in its bids.

When it comes to how the Eagles found Panasonic, the team and the company already had an existing relationship, as Panasonic’s video-board division had previously supplied displays for the Linc. According to Abelson, Panasonic went through a performance test at several Eagles games last season, bringing in Wi-Fi gear to see if the new technology could provide coverage to areas where the Eagles said they had seen lower-quality coverage before. One of the forerunners in the NFL in bringing Wi-Fi to fans, the Eagles had previously used Extreme Networks Wi-Fi gear to build a fan-facing network in 2013. Though the Eagles would not comment about the selection process, after issuing an RFP this past offseason the team chose Panasonic for a new network, which Abelson said was deployed in three months during the football offseason.

Re-opening the debate for antenna placement?

Though Mobile Sports Report has not yet been able to get to Philadelphia to test the new network in a live game-day situation, if Panasonic’s new gear works as promises the company may find many potential interested customers, especially those who had shied away from deploying under-seat networks due to the construction issues or costs.

The Panasonic system may be of particular interest to indoor arenas, like hockey and basketball stadiums, where the gear could be potentially mounted in catwalk areas to cover seating. John Spade, CTO for the NHL’s Florida Panthers and BB&T Center in Sunrise, Fla., has tweeted favorably about a Panasonic deployment going in at the arena whose networks he oversees:

But even as the impressive 8.76 TB mark seen at the NFC Championship game now sits as the third-highest reported Wi-Fi data use event we’ve heard of (behind only the 10.1 TB of Wi-Fi seen at Super Bowl 50 and the 11.8 TB seen at Super Bowl 51), that number may fall a bit down the list if we ever get verified numbers for some network totals we’ve heard rumors about lately. (Or even any older ones! C’mon network teams: Check out the list below and let us know if we’ve missed any.)

So far this season, we haven’t gotten any reports of Wi-Fi usage out of the network team at Atlanta’s Mercedes-Benz Stadium (which recently hosted the college football playoff championship game), and we’ve only heard general talk about oversized playoff-game traffic at U.S. Bank Stadium in Minneapolis, home of Sunday’s Super Bowl 52. Like Notre Dame Stadium, U.S. Bank Stadium uses a mostly railing-mounted AP deployment in its seating bowl; both networks were designed by AmpThink. We are also still waiting for reports from last week’s AFC Championship game at Gillette Stadium, where the previous non-Super Bowl top mark of 8.08 TB was set in September; and from any games this fall at AT&T Stadium in Arlington, Texas, where the NFL’s biggest stadium has 2,567 Wi-Fi APs.

Will overhead still be able to keep up as demand for more bandwidth keeps growing? Will Panasonic’s claims of lower costs for equal performance hold up? At the very least, the performance in Philadelphia could re-open debate about whether or not you need to deploy APs closer to fans to provide a good Wi-Fi experience. If all goes well, the winners in renewed competition will be venues, teams, and ultimately, fans.

NFL exec: U.S. Bank Stadium Wi-Fi network ‘in a strong place’ ahead of Super Bowl LII

January 19, 2018 by

Like many football fans, I was jaw-dropping excited while watching the Minnesota Vikings’ dramatic walk-off touchdown win in last Sunday’s playoff game against the New Orleans Saints. Unlike many football fans but probably more like our readership, my next thought while watching the celebrations was: I hope the Wi-Fi holds up!

According to a top NFL IT executive who was at the game, the Wi-Fi network at U.S. Bank Stadium was more than up to the load applied to it by the Vikings’ exciting win and victory celebration, a good stress test ahead of the stadium’s hosting of Super Bowl LII on Feb. 4. “There were an amazing amount of [Wi-Fi] connections” after the game’s end, said Aaron Amendolia, vice president of IT in the NFL’s office of the CIO, in a phone interview Thursday.

The “massive spike” in connectivity after the game’s exciting conclusion produced numerous social media posts from fans present, mainly on Facebook and Snapchat, Amendolia said. Though he didn’t have full networking statistics from the game, Amendolia did share one interesting number, the fact that there were approximately 37,000 unique connections to the Wi-Fi network during the game — a total greater than that at last year’s Super Bowl LI in Houston, where 35,430 fans out of 71,795 in attendance at NRG Stadium used the Wi-Fi at some point. Attendance at Sunday’s playoff game in Minneapolis was 66,612.

“I feel we’re in a strong place now” with the Wi-Fi network at U.S. Bank Stadium, Amendolia said. “We’re hoping to set some new records.”

Still no sign of bandwidth demand decline

Amendolia, part of the NFL’s networking team that ensures good connectivity at the league’s championship event, said testing work on the AmpThink-designed network (which uses Cisco Wi-Fi gear) started last year, and then ramped up through the current season.

“Starting with the presason [games] we had staff sitting in seats, doing Facebook, visiting websites,” said Amendolia. “The unique architecture in each stadium makes Wi-Fi [performance] unique. We had people sitting in odd corners, and next to big concrete structures.”

Ever since Wi-Fi has been a part of Super Bowls, the total data used and numbers of fans connecting have steadily increased each year, always setting current records for single-day use of a large venue network. At Super Bowl 49 in 2015, fans used 6.23 terabytes of data on the Wi-Fi network at the University of Phoenix Stadium in Glendale, Ariz.; the next year, it was 10.1 TB of Wi-Fi at Levi’s Stadium in Santa Clara, Calif.; and last year at NRG Stadium in Houston there was 11.8 TB of Wi-Fi data used. (Cellular data use on stadium DAS networks has also increased apace, from almost 16 TB at Super Bowl 50 to more than 25.8 TB last year.)

What’s interesting is that networking usage totals for games the following NFL season usually increase as well, not to Super Bowl levels but surpassing marks from years before. For this season’s opening game at the New England Patriots’ Gillette Stadium, the Wi-Fi network there saw 8.08 TB of data used, a mark that trails only the last two Super Bowls.

“Super Bowls set the benchmark for the next season,” said Amendolia, who agrees that there may never be an end to the growth.

“Even if [current] usage levels off, there’s new technology like augmented reality and wearable glasses,” Amendolia said. “How does that change the future?”
