Thursday morning at CES here in Las Vegas Sacramento Kings owner Vivek Ranadive is scheduled to speak and will no doubt tell the CES attendees about the Kings’ new stadium, the Golden 1 Center, and about how tech-loaded it is by design. But Wednesday night details emerged about the vendors helping the Kings with their extensive wireless deployment, and the list includes Ruckus Wireless, DAS Group Professionals, Brocade and CommScope, among others.

As previously reported by Mobile Sports Report, Ruckus gear will be used in the Wi-Fi deployment not just at the 17,500-seat Golden 1 Center, but also in the surrounding area, which is supposed to include a new public plaza and other developments, including hotel, office, housing and retail space. In the press announcement of all the tech underpinnings the Kings do not state exactly how many Wi-Fi APs will be in the stadium proper but instead say that there will be “more than 1,000” APs in both the stadium and surrounding plaza and developments. UPDATE, 1/10/16: The Kings have responded to clarify, saying there isn’t yet an exact AP count but density is expected to be in the area of one AP per 15 seats, which would put the final total well over 1,000 APs and easily be the most APs for a Wi-Fi deployment in any basketball/hockey arena we know of, and perhaps the most dense of any sporting venue (for now).

Since we’re nit-picking we’ll also question the Kings’ claim that Golden 1 Center will be “the first arena in the world to implement wide-band, multimode fiber technology” on the backbone, a curious claim since the fiber-based network at Texas A&M’s Kyle Field is already operational (and working quite well). UPDATE, 1/10/16: The Kings have responded and say that their implementation differs from Texas A&M’s passive optical network; we will provide further details and comparisons in the near future.

The DGP team at Levi’s Stadium for a summer interview included, L to R, Derek Cotton, director of engineering; Steve Dutto, president; and Vince Gamick, VP and COO. These guys are probably smiling again now that DGP will be part of the Golden 1 Center deployment.

Frothy claims aside, we are very interested in hearing more about the venue’s tech underpinnings, especially the combined DAS/small cell deployment being installed by DAS Group Professionals, the builders of the DAS network at Levi’s Stadium in Santa Clara, Calif. According to the Kings’ release wireless powerhouse CommScope will be part of the infrastructure as well (along with bandwidth provider Comcast, a deal that was announced last month), and network backbone gear provider Brocade will also be involved, making Golden 1 Center a mini-me kind of version of Levi’s Stadium, where Comcast, Brocade and DGP are all also involved. (This is also not so surprising since we have heard rumors that the Kings hired some IT folks who previously worked on the Levi’s Stadium deployment.)

If there is an outlier to the deal it’s the Wi-Fi presence of Ruckus, which has had a tough year when it comes to potential stadium deployments. First Ruckus had a deal for Wi-Fi at the new San Jose Earthquakes soccer stadium but lost that when Avaya booted Ruckus off the pitch by purchasing naming rights to now-Avaya Stadium for $20 million. More recently, Ruckus was part of an initial winning bid with integrator 5 Bars for the Wi-Fi deployment at Houston’s NRG Stadium, but was replaced at the last minute by Extreme Networks to unspecified and unconfirmed pressure, most likely by the NFL. On the plus side, Ruckus gear was used for the Wi-Fi deployment at Angels Stadium in Anaheim, as well as at Indian Wells Tennis Garden, site of the big spring pro tennis tourney.

We will try to fill in more blanks and details during Ranadive’s appearance Thursday (like who will be designing the team app, which we are guessing might be VenueNext), but the real proof of the Golden 1 pudding won’t come until October, since you never can tell how a stadium network will work until it’s turned on for a full house of device-holding fans. That’s why we don’t put much stock in theoretical claims, like the Kings’ ridiculous promise that the network can handle “over 500,000 Snapchat posts per second” — that’s some fast fingers for a full house of 17,500, no? When it comes to feeds and speeds we are firmly in the show-me house, so we hope the Kings and Golden 1 Center will be as open with their real-world statistics come next fall as they are with press-release superlatives now.

DGP upgrades Levi’s Stadium DAS in preparation for Super Bowl 50

September 14, 2015 by Paul Kapustka 5 Comments

After deploying one of the biggest and most robust stadium DAS networks at Levi’s Stadium last year, what did DAS Group Professionals do for an encore?

How about completely re-deploying a new DAS at Levi’s Stadium during the football offseason, just about doubling the capacity in a construction project that took place at a “live” venue instead of one under construction?

The ambitious renovation of the not-quite-1-year-old Levi’s Stadium DAS was all done in the name of Super Bowl 50, the NFL’s big game that is coming to Levi’s Stadium in February 2016. According to DGP president Steve Dutto, the huge jump in wireless traffic statistics at Super Bowl XLIX last February got the major wireless carriers working early to assure that the NFL’s 50th Super Bowl would have enough cellular capacity.

In addition to new antennas from DAS gear supplier JMA Wireless that can be more finely tuned, and more antennas and remote units to beef up coverage and support more cell sectors inside Levi’s Stadium, DGP and stadium owner the San Francisco 49ers also increased the DAS footprint outside the stadium in the adjacent parking lots, addressing what Niners COO Al Guido told MSR was a “primary concern” heard from fans during the inaugural Levi’s Stadium season.

Though work on the DAS will likely continue throughout the season, most of the construction and deployments were expected to be in place for the Niners’ regular season opener tonight versus the Minnesota Vikings.

Ready for another ‘Super’ cellular day

Though the unofficial totals for DAS traffic at the last Super Bowl that were in excess of 6 terabytes were the highest we’ve ever seen reported, DGP’s Dutto said that the top wireless carriers are expecting as much as 2.5 times that amount of traffic at Super Bowl 50, a load that might have swamped even the previously robust Levi’s Stadium DAS.

“The [cellular] traffic at the Super Bowl this past year was greater than anything anybody had seen,” Dutto said in a recent interview at Levi’s Stadium. All the carriers, he said, were “amazed” at the traffic jump from the year before, when AT&T and Verizon Wireless reported a combined total of about 2.5 TB of cellular data at Super Bowl XLVIII at MetLife Stadium in New Jersey. (For what it’s worth the Wi-Fi traffic also just about doubled, from 3.3 TB to 6.23 TB.)

The DGP team at Levi’s for our interview included, L to R, Derek Cotton, director of engineering; Steve Dutto, president; and Vince Gamick, VP and COO.

So even though the Levi’s Stadium DAS performed exceedingly well — according to Dutto “we turned it on and from day one it exceeded expectations” — and that there wasn’t any capacity problems during the Niners’ 2014 season, the expected impending crush coming in February spurred what Dutto called “carrier-driven upgrades” that included the need to take over some previous storage-room space to house the increased amount of head-end gear.

Under seat DAS antennas part of the upgrade

Inside the stadium itself, Dutto said that Verizon will expand its coverage from 60 to 80 sectors, while AT&T will increase from 45 to 54 or more sectors. DGP will increase its “zones” of coverage in the main seating bowl from 23 to 40, and will go from 250 antennas to 400, and from 330 remote units to 450. There will also be plenty of new antennas from JMA that Dutto said have “greater gain and sharper patterns” to enhance coverage.

“It’s almost like deploying twice the network in the same amount of time,” Dutto said. The other big difference from last year, however, was that Levi’s Stadium was open for events this past football offseason, from WrestleMania 31 to a NHL Stadium Series game to concerts with the Grateful Dead and Taylor Swift.

Another view of the antennas on the concourse overhangs

Though there was more than enough cabling areas and pathways to make the retrofit easier, Dutto said working around the live events increased the deployment degree of difficulty. But even with new head end rooms and extras like under-seat DAS antennas (a new deployment method at Levi’s Stadium for DAS), 20-plus new antenna placements in the parking lot and the accomodation of new 2.5-GHz spectrum for Sprint, Dutto said that the new network was expected to be at least “90 percent complete” before the season’s start.

As is regular with lead-ups to Super Bowls, there will likely be even more network tweaking and adjustment up until the last minute before kickoff on Feb. 7, 2016.

A ‘heart-attack” moment and hot dog machines

With any luck, the new network will work as well as the old one, and will hopefully light up without the “heart attack moment” that happened just before opening day last fall. Dutto and his team of Derek Cotton, director of engineering, and Vince Gamick, DGP’s vice president and COO, told of coming to Levi’s Stadium for the regular season opener last September and almost keeling over when they couldn’t detect the DAS network anywhere inside the building.

As it turns out, Dutto said that the major wireless carriers had forgot to turn down the power on their macro towers at the cell sites that surround Levi’s Stadium, which basically overwhelmed the internal network since Dutto said the outdoor cell sites operate at 80 watts, compared to the 2-watt in-stadium DAS network.

“There are six cell sites within hundreds of feet [of Levi’s Stadium] and since they hadn’t turned them down, we couldn’t see the network in the stadium,” said Dutto, whose pulse was revived when the situation was quickly rectified.

At least the Levi’s Stadium DAS couldn’t be turned off by stadium workers or blacked out by hot dog machines, problems that DGP encountered at the Niners’ old home, Candlestick Park, where DGP deployed a test DAS in the 49ers’ final season there in 2013. According to Dutto, for some reason the DGP network was connected by utility PG&E to the same electrical routes as the cookers for stadium hot dogs — and when those were turned on one Sunday the system was overloaded, bringing the DAS down with sausages.

The Candlestick DAS also suffered an outage when the park rangers who lived at the stadium thought the equipment air conditioners were too loud, so they turned them off — setting off multiple alarms for Dutto and his network administration team.

Safe to say, similar problems aren’t expected to arise as DGP and the Niners prepare Levi’s Stadium’s cellular network for Super Bowl 50, a tough task but one with rewards on both a personal and business level.

“This has been fun, and the Niners have been great to work with,” said Dutto.

Extreme, DGP part of Wi-Fi and DAS upgrade coming to Florida State’s Doak Campbell Stadium

September 3, 2015 by Paul Kapustka Leave a Comment

Extreme Networks and DAS Group Professionals have been selected by IMG to build a new Wi-Fi and DAS network respectively at Florida State University’s Doak Campbell Stadium, the 82,300-seat home of the Seminoles football team, according to the school’s website.

Extreme, which has mainly made its stadium name in pro football venues, has one other college deployment that we know of but nothing on the scale of regular national-championship caliber FSU. DGP, which was relatively unknown until its Levi’s Stadium deployment last year, is now racking up big deals in a hurry, following its selection (also alongside Extreme) by the Chicago Cubs for new communications infrastructure at Wrigley Field.

Since the press release said the deals are only so far at the “evaluation” stage that means that Wi-Fi and DAS aren’t available yet. More details on this deal as we hear them, in what is shaping up to be a very busy season of new stadium deployments. This also appears to be the first fruit of the Extreme/IMG relationship announced last winter.

Stadium Tech Report: DAS Group Professionals makes a name for itself with Levi’s Stadium DAS

September 11, 2014 by Paul Kapustka 3 Comments

If you look around at the walls, ceilings and overhangs at Levi’s Stadium, it’s hard to miss the small square boxes with the off-white color and a “DGP” logo in one corner. While the wires hanging out the back of each box make it an easy guess that the equipment has something to do with wireless networks, even many industry insiders may not know the company behind the boxes and the three-letter acronym.

Meet DAS Group Professionals, the Bay Area firm in charge of deploying a distributed antenna system (DAS) to make sure your cell phone gets a good signal at San Francisco 49ers games and any other event inside the 68,500-seat Levi’s Stadium. And while you might not be familiar with DGP, rest assured the company is extremely familiar with cellular deployments for large public venues, having installed similar DAS networks for airports, casinos and hotels, and even for San Francisco’s BART train system. Of course, most of that work was done when the company was called Forza Telecom, before changing its name to DGP earlier this year, another reason why “DGP” may not have rung any bells.

“It may appear like we just fell out of the sky, but we’ve actually built quite a few [DAS] systems,” said Steve Dutto, president of DGP, in a recent phone interview. “We’ve got years of experience.”

DAS: The Rodney Dangerfield of stadium connectivity

One thing that keeps firms like DGP in the shadows is the relative obscurity of DAS itself. While most people generally understand how cell phones work — you turn on your phone, and it connects to an antenna somewhere on a tower or rooftop — in crowded public facilities like stadiums, traditional cellular networks with towers several miles apart can’t handle the concentrated capacity. To provide connectivity for areas with large crowds, the latest tactic is to deploy a DAS, a network of lots of smaller antennas. Originally deployed in places like office buildings, hotels and convention centers, DAS is rapidly gaining favor in stadiums and arenas, helping to alleviate the “no signal” problem that has cropped up in many venues the past few years.

And while stadium Wi-Fi gets lots of headlines whenever it gets deployed — probably thanks again to the widespread understanding of how Wi-Fi works — there are already far more DAS deployments in stadiums than Wi-Fi, mainly because cellular carriers will pay almost all the associated costs of a DAS buildout to make sure their customers get a signal. According to our most recent 2014 State of the Stadium survey, 71.4 percent of our respondents said they had a full DAS at their facility, while only 35.7 percent had fan-facing Wi-Fi.

Steve Dutto, president, DGP

How does a DAS work? Usually, either a major cellular carrier or a third-party “neutral” host like DGP will build out the antenna infrastructure, which includes many small antennas and then cables to bring the connections back to a wiring room or data center. There, cellular carriers install their own cell-tower back-end gear to authenticate customers and to provide a connection to the company networks and the Internet. Since it’s in the cellular carriers’ interest to keep their customers connected (and using billable minutes and data), carriers will often pay the full cost of a DAS infrastructure by building and running it themselves. In the case like Levi’s, where DGP is the “neutral host,” DGP builds the infrastructure and then charges cellular carriers to use it.

Such deals are rarely publicized, and Dutto would not comment on how much each carrier was being charged to use the Levi’s DAS — though industry gossip has the figure somewhere around $5 million per carrier per year. And just like fight club, for many deployments the first rule of DAS is that you don’t talk about DAS, because no cellular carrier ever wants to admit that its network might need help. So just like Rodney Dangerfield, DAS often doesn’t get a lot of public respect. But at Levi’s Stadium and many other sports and entertainment venues, DAS is a booming business that would be sorely missed if it wasn’t there.

The ‘dream and the nightmare’ of building the Levi’s DAS

Now that DGP’s 700-plus antenna DAS deployment is up and running at Levi’s, Dutto can breathe a small bit easier. While the network is good business for the company and an obvious prominent calling card for the future, the aggressive deployment timeframe probably isn’t something Dutto is eager to repeat.

“Levi’s Stadium was both a dream and a nightmare [for DGP],” Dutto said, due in part both to the Niners’ aggressive performance expectations and the rapid buildout schedule. Of course, DGP was somewhat used to working quickly with the Niners — when the company put a DAS in Candlestick Park back in 2012 to solve that stadium’s legendary lack of connectivity, Dutto said it was deployed “in about 90 days.”

The success of the Candlestick deployment, Dutto said, led to the Niners offering the Levi’s DAS gig to DGP. With it, however, came the need to match the team’s out-front statements about how the stadium was going to be the best ever in terms of wireless connectivity. And with many people not knowing or not bothering to switch their phones to Wi-Fi, the Levi’s DAS, like most stadium DAS deployments, would probably handle most of the wireless connections.

“We knew that it needed to be significantly better than anywhere else, right at the launch,” Dutto said. While the late addition of an early August soccer game at Levi’s pushed deployment schedules ahead even faster, Dutto said in the end it helped DGP overall.

“I wasn’t a big fan of getting ready for that date [the Aug. 2 soccer game was Levi’s first event] but it was a blessing in disguise,” Dutto said. “The trouble with a network is that you can’t really test it until everyone shows up. We got some good data from that event.”

After the “daily and nightly” discussions with the Niners’ tech team about antenna placements and other matters, the DAS network performed well when it mattered, during the Niners’ two preseason games on Aug. 17 and 24. According to a traffic report from the stadium tech team, the DAS network carried a combined 1.02 terabytes of wireless traffic for the two preseason games, which is on par with activity seen at big events in the past, like Super Bowls. According to Dutto DGP’s internal tests showed that few, if any, calls were dropped or didn’t connect.

“We’re at 98 percent [network performance] already, without [the network] being fully optimized,” Dutto said.

RF challenges and too many iPhone 4 customers

While many of the stadium’s Wi-Fi antennas are well hidden — including the ones in boxes under seats — the DAS antennas are a bit more prominent, especially if you are near where the first overhang comes close to the seats.

“Unfortunately, with Levi’s exposed steel-beam construction, if you want the DAS to work, you’re going to see it,” Dutto said. “It’s hard to be stealthy in there.”

And in many cases there isn’t just one but instead two DGP antennas side by side, which reflects the company’s decision to actually build two parallel DAS systems to better accomodate more wireless carriers. According to Dutto, AT&T and T-Mobile are based on one system, while Verizon Wireless, Sprint and public safety communications are handled by the other one. Currently, all the carriers are live on the DAS except for Sprint, which is still in the process of installing its back-end equipment.

DAS antenna in “Faithful Mile” area

One of the biggest challenges for DGP, Dutto said, comes from outside the stadium, and not inside. Like other open-air stadiums located in city cores, Levi’s Stadium faces significant interference from cellular antennas on nearby office building rooftops, as well as from the Santa Clara Convention Center right across the street.

“Less than a half mile from Levi’s you can see seven different rooftop cell sites,” said Dutto, who said the flat, open terrain around the stadium increases the ability for those signals to interfere with the stadium DAS deployment. Target Field in Minneapolis had some similar problems with cell antennas on nearby office buildings.

“We’ve done a lot of work with the carriers to adjust their macro networks around the stadium,” Dutto said. “We’ll do more of that as we go, and expect it to get better.”

And while Levi’s Wi-Fi network has shown itself to be incredibly robust, Dutto said that cellular connectivity over the DAS might be even faster than Wi-Fi in many instances, especially if fans have later-model phones with 4G LTE.

Even though Dutto said DGP’s testing recorded download speeds of up to 200 Mbps — and 65 Mbps sustained — he acknowledged that many Levi’s patrons might never see those kinds of numbers unless they snap up some of the new iPhone 6 models introduced by Apple this week. According to network stats collected by DGP during the preseason games, a lot of fans may be ready for an upgrade.

“There’s a lot more iPhone 4 users out there than we thought,” Dutto said.

Holy Terabyte! First football crowd at Levi’s Stadium uses 2.13 TB of Wi-Fi traffic, with nearly 25K fans on Wi-Fi at once

All those predictions about Silicon Valley people using a stadium network more than other fans? It looks like they’re true.

The network numbers are in for the first football game at Levi’s Stadium, and they are pretty amazing: According to Dan Williams, the vice president of technology for the San Francisco 49ers, the Levi’s Stadium Wi-Fi network carried 2.13 terabytes of data during last Sunday’s preseason game, with a peak of 24,775 fans on the Wi-Fi network at the same time. Those numbers are comparable to the latest Super Bowl at MetLife Stadium in New Jersey, where according to AT&T and Verizon there was approximately 2.5 TB of data used on wireless networks.

The kicker to the Niners’ stats — they do NOT include any traffic figures from the Levi’s Stadium DAS, the distributed antenna system that is meant to provide enhanced cellular coverage in the stadium. What follows is an email Q-and-A with Williams, who kindly answered our extensive list of questions. The real question is, if Niners fans are hitting terabyte levels during preseason games, what’s going to happen when the season starts for real? And the instant replay function in the team app is live? Read on for some great insight from Williams. Additional editor’s note: The companies talked about include Aruba Networks, the provider of Wi-Fi gear; Brocade, provider of back-end networking gear and integration; DAS Group Professionals, the integrator and deployment team behind the DAS (the network of small antennas that improve in-building cellular coverage).

Mobile Sports Report: what was the peak number for simultaneous Wi-Fi connections? The average?
Dan Williams: We peaked at 24,775 (roughly 38% of attendance) concurrent connections with an average of 16,862 (roughly 25% of attendance).

MSR: When did connections spike? When did they start and then tail off?
Williams: We had two spikes, 1:02 p.m. [editor’s note: kickoff was 1 p.m.] with a system wide peak of 2.3Gbps and then again at 1:53 p.m. with 1.7Gbps. We averaged more than 1Gbps for more than two hours.

Niners VP of technology Dan Williams attempts to fix my Droid 4 Wi-Fi issues (while trying not to laugh at the fact that I actually have and use a Droid 4)

MSR: What was the total data tonnage on the Wi-Fi network?
Williams: We offloaded 2.13 Terabytes during the event.

MSR: What were the usage patterns with the app — which feature did people use most?
Williams: We had a great deal of usage throughout Sunday. The food ordering app usage was top of the list with ticketing being a close second while video would take third from a feature standpoint.

MSR: What are the plans with the instant replay feature… when will it be live (and can you explain why it was held back)?
Williams: We felt a lot of folks were happy with the livestream, so we wanted to focus more on a couple of core features with food ordering and ticketing a bit more at this point. Replays will be available to all by the first regular season home game.

MSR: Can you explain exactly how the location feature works… does it require Bluetooth to be on?
Williams: The location service is mainly built around low-energy Bluetooth, BLE. We have a number of beacons placed throughout the open areas and points-of-interest which allow the app to identify your location through proximity. Aruba helped us build this as well. GPS is also used but the primary resource is Bluetooth. The app prompts users to enable Bluetooth to provide improved location awareness.

MSR: Can you provide any stats on the DAS performance?
Williams: The DAS held up really well. Like WiFi, we found some areas that need tuning. Unlike WiFi, the carriers protect a lot of their specific data but they have told us they are very happy with the system DGP helped us with. It is important to note our DAS and WiFi have been built to compliment each other and I think between Aruba and DGP, we did that very well. Most come here looking to connect to WiFi but our story internally has been we are going to have an awesome connectivity play regardless of medium.

MSR: Could you guys see any [more] of the 2.4 GHz issues like the one I had?
Williams: As you know, 2.4GHz is limited with non-overlapping channels so we suspect a number of legacy devices may have some problems. That said, we had a ratio of 2:1 with respects to 5GHz to 2.4GHz [usage] which shows a good deal of 2.4GHz usage. We know we still have some optimizations to do in the upper bowl and upper concourse while we continue to fine-tune the main bowl and concourse as we noticed our cell edge was weaker than expected when the stands were full. Our Aruba team did a great job capturing real-time data during the event as there is really no other way to test this stuff without a full venue. We will make some tweaks and continue to learn more from every event we host. Between Aruba, Brocade, and the 49er tech staff, we are not resting on our laurels. We know there is more to do.

Stadium Tech Report: Levi’s Stadium network lives up to hype, but team app still needs work

August 17, 2014 by Paul Kapustka 11 Comments

Levi’s Stadium from Section 244. All photos: Paul Kapustka, Mobile Sports Report

At the very least San Francisco 49ers fans Sunday could take heart in the fact that the wireless network in Levi’s Stadium largely lived up to its advance billing, performing quite well even as the team on the field sputtered and failed to connect. In its first “real” test with an almost-full house on Sunday the Levi’s Wi-Fi and cellular networks seemed to work well throughout the game, delivering solid speed test results from almost every part of the new 68,500-seat facility, even as Colin Kaepernick and the rest of the 49ers were dealt a 34-0 preseason drubbing by Peyton Manning and the visiting Denver Broncos.

And just like the team, the Niners’ stadium technology lineup still has some weak spots that will hopefully be fixed before the regular season home opener on Sept. 14. Among the disappointments Sunday was a no-show by the highly heralded instant replay feature, the crown jewel of the new Levi’s Stadium app. We also experienced some location-connection problems with one of our devices, exposing what we consider a flaw in the Levi’s app, namely an over-reliance on location technologies to enable key parts of the app, like wayfinding and on-site video streaming.

Ticket scanner with Niners visor to block sun

Some other not-so-advanced technology flaws that could use fine-tuning include the volume level on the main stadium public-address and announcing system, which was so loud that it made it a struggle just to talk to the person next to you for long stretches of time. The ticket scanning machines also seemed to have issues working in the bright sunlight, a problem that found a low-tech fix when ticket personnel placed Niners’ visors around the tops of the machines to shade the scanning area. And many concession stands around the stadium were unable to serve guests or could only take cash because the staff operating the stands said they weren’t given access codes to the point-of-sale systems.

Overall, however, the first football game at Levi’s was a success on many levels, including the fantastic sight lines available from most seats and largely incident-free travel and parking operations, with noticed improvements especially on the VTA light rail front that struggled mightily during the stadium’s opening-event soccer game two weekends ago. Most fans also probably got a little weight loss from the no extra-charge sauna situation, thanks to the cloudless day and bright sun that bathed most of the seats in searing heat for long times after the 1 p.m. start.

Smooth start for early VTA riders

What follows here is a somewhat minute-by-minute account of my trip to the game, and my experience with the network and stadium operations on site.

Mtn View lot sign, not in operation at 9:30 a.m.

Since I wasn’t given press access to the game, Mobile Sports Report attended like a regular fan, purchasing a single ticket through the NFL Ticket Exchange service on the 49ers’ web site. My plan to get to Levi’s from San Mateo was to drive to downtown Mountain View, park there and take VTA the rest of the way. (I didn’t take CalTrain mainly because I didn’t want to have to sync my return schedule with the CalTrain options going northbound on Sunday.)

Though I was somewhat incredulous about having to buy tickets online — VTA said that the ticket machines in Mountain View would be shut down Sunday to keep big lines from forming — upon further review the VTA app was slick and easy to operate and understand. After purchasing a ticket for $6.50 Saturday night I activated it Sunday, and showed it at the gate where they checked boarding passes. For people who didn’t have tickets there was a tent set up where they could buy a pre-loaded Clipper card for $10 good for a day’s worth of VTA riding. There was an abundance of VTA workers on hand, as well as a large and very obvious police presence. As a nice touch there was also a large bank of porta-potties, and behind the trains there were express buses waiting, according to one VTA employee, in case of crowd overloads.

“We learned some lessons from two weeks ago,” he said.

If there was a glitch in the VTA operations it was with the city of Mountain View — though a couple city lots were designated as places where fans could buy all-day parking passes, and there were clear signs to those lots, at 9:30 a.m. those lots were not yet staffed with anyone to pay; MSR found one sign leaning up against a post, waiting to be deployed. Fans could also park in the CalTrain lot for $5, payable via the CalTrain track podium ticket machines.

Fans transferring from CalTrain to VTA at Mtn View station

I boarded the first VTA train to leave for the stadium, along with many fans who had just gotten off CalTrain. The pleasant, air-conditioned trip took just 27 minutes, passing many Silicon Valley company headquarters and one neighborhood with “no parking here” patrols before stopping pretty much right at the Levi’s Stadium entrance. A few steps later I was in the parking lot, and took the first of many Wi-Fi speed tests and got a signal of 29 Mbps download and 23 Mbps upload, a good sign for network operations.

Looking for Wi-Fi, finding lots of it

DAS antenna in “Faithful Mile” area

Once inside the gates — and past the shaded scanners — I started speed testing in earnest, with the two devices I brought with me: A Motorola Droid 4 on Verizon, and a Samsung Galaxy Note 3 on AT&T. While waiting for the main stadium gates to open at 11 a.m. I got the weakest Wi-Fi signals of the day along the “Faithful Mile” area where promotional booths from sponsors kept early arrivers entertained. Wi-Fi on both devices out there only hit 2 to 3 Mbps on the download, while cell signals on both devices were in the 6-7 Mbps download range. Since I could see multiple DAS radios in the area but not any Wi-Fi access points I wasn’t too surprised; but it was an unusual area not to be blanketed with Wi-Fi, especially since there was good access a couple hundred yards away in the parking lots.

After finally entering the stadium proper, I ran into Niners president Paraag Marathe — who said he was “nervously excited,” and looked ready to start sweating in his suit and tie. “We’ve just got to make sure everything works today,” Marathe said, shaking my hand. Then I went up the escalator and saw the “Kezar pub,” an open-air bar filling the top area above the Intel gate. There, draft beers like Shock Top and Goose Island IPA were available for $11, and bottled beers available for $10.25.

As I started walking around the outside concourse I took my first speed test in the stadium and it blew the needle off the edge: 57.92 Mbps download, 41.00 Mbps upload.

A few minutes later on the inside concourse (where most of the concession stands are) I hit 27.85 Mbps/21.34 Mbps, still impressive. Then I tried to launch the app, and — problem. Apparently the device wasn’t connecting because it wouldn’t show my location on the wayfinding app. Luckily, right in front of me was Racquel, one of the “NiNerds,” the team’s new staff of technical experts who are there to help fans make the app work. But Racquel couldn’t solve my problem, even after we both tried turning on all location services, including Bluetooth.

Racquel the NiNerd

“I can try to find another NiNerd who might know more about this device,” offered Racquel, who was visibly dismayed at her failure to help solve my problem. Instead, I moved on, hoping that the problem would solve itself later. But it didn’t.

Failure to locate… and other app problems

After downloading the Levi’s app to both devices over the weekend, I noticed that the first item on the app list of functions — Tickets — required me to “sign in” with my “Stadium Ticket Account,” something I didn’t have and didn’t know how to get. I did figure out how to enter my purchased seat location (which I could have used to order food to my seat, or for the express pick-up option), but I could never get the location feature to work on the Samsung device, which kept me from being able to see the live streaming TV option (I kept getting a message that said, “You must be at the stadium to play this video”). I was able to watch the live TV option on the Motorola device, after turing on location services. But for both devices — and, as it turns out, for everyone in the stadium — the final feature on the app, Game Center, where we were supposed to be able to see all the instant replays we could handle, remained labeled “coming soon.”

Finally sitting in my most excellent seat — section 244, row 3, seat 17 — I noticed that the Motorola device could no longer connect to Wi-Fi, even as the Samsung device was hitting marks in the 15-16 Mbps range. I started tweeting about the problem, and instead of a NiNerd coming to help me I got a personal visit from the Levi’s version of a Jedi Master, namely Dan Williams, the team’s vice president of technology. (Never underestimate the power of a complaining tweet!)

Niners VP of technology Dan Williams attempts to fix my Droid 4 Wi-Fi issues (while trying not to laugh at the fact that I actually have and use a Droid 4)

On my own, I had guessed that the Droid’s inability to connect came from its having only a 2.4 GHz Wi-Fi radio. If you’re not familiar with Wi-Fi networks, the 2.4 GHz band of unlicensed airwaves is what most first-generation Wi-Fi networks used; more recent devices are able to also use the 5 GHz band of unlicensed airwaves, which simply offer more channels and more bandwidth. The iPhone 5s, for example, mainly uses 5 GHz for Wi-Fi, as does my Samsung Note.

In scanning the available Wi-Fi networks, I had also noticed something else that I thought could be gumming up the Droid’s connection — a bunch of personal Wi-Fi hotspots in the immediate area, including several labeled as GoPro cameras. After curiously examining my Droid 4 — and its slide-out keyboard — Williams and a technician from Wi-Fi gear provider Aruba Networks concurred that my device was getting bogged down in the 2.4 GHz mess, and also wasn’t refreshing the available networks list, a device-specific problem.

Bottom line? Levi’s is no country for old phones.

Initial verdict: Wi-Fi and cellular is world class… but app needs work

After staying into the third quarter — and visiting another friend in section 109, where I got another hefty Wi-Fi speed test (24.42/25.39 Mbps) — I followed the lead of many fans and took an early leave of Levi’s, which meant no lines at the VTA trains and just a couple short delays due to track congestion that stretched the return train trip to 40 minutes. Overall, my travel to and from the stadium from San Mateo took just over an hour each way, a happy stat to report.

My initial verdict is that the Wi-Fi and DAS (cellular) networks delivered as promised, with solid speeds all around the stadium every time I checked. It’s no small accomplishment just to deliver such world-class service to such a crowded space, especially in the middle of Silicon Valley. True to its roots, the crowd Sunday was device-happy, with many iPads and GoPros being carried around as video cameras, in addition to all the phones that were in constant use. It’s a tribute to Williams and his staff, as well as the technology suppliers like Aruba, Brocade, Comcast (backbone bandwidth supplier) and DAS Group Professionals, who built the distributed antenna system (DAS) which brings advanced cellular connectivity inside the gates, to have built a solid network that worked well on its first big test.

The team app, however, did not even come close to living up to its advanced billing. To equal the network I think the app needs more advance instructions, especially on the ticketing/registration options as well as on the location services needed to make everything work. And until we see the multiple-camera angle live replays in action, to me the app is an incomplete project. The good news is, the Niners and their technology teams have several weeks to make improvements, including another preseason game Aug. 24 against the San Diego Chargers.

It’d also be helpful for the team to reach out a bit more to the VTA and players like the City of Mountain View, since the VTA site maps and Mountain View’s parking maps are far from what you would call “advanced design.” I think it’s up to the Niners to help pay for improvements to the city and transportation entities’ technology offerings, simply because of the burden placed on those operators by the fans going to Niners’ games. At the very least, more links from football to getting-there operations seems in order, instead of trusting that all parts of the operation will work in sync.
