The history of high density (HD) Wi-Fi deployments in stadiums and arenas is short. Yet the the amount of change that occurred is significant; both in terms of how these networks are deployed and why.

Venue operators, manufacturers, and integrators are still grappling with the particulars of HD Wi-Fi in large open environments, even though there are a substantial number of deployed high quality implementations. Below, I’ve shared our perspective on the evolution of HD Wi-Fi design in stadiums and arenas and put forth questions that venue operators should be asking to find a solution that fits their needs and their budget.

AmpThink’s background in this field

Over the past 5 years, our team has been involved in the deployment of more than 50 high-density Wi-Fi networks in stadiums throughout North America. In that same period, the best-practices for stadium HD Wi-Fi design have changed several times, resulting in multiple deployment methodologies.

Each major shift in deployment strategy was intended to increase total system capacity [1]. The largest gains have come from better antenna technology or deployment techinques that better isolated access point output resulting in gains in channel re-use.

What follows is a summary of what we’ve learned from the deployments we participated in and their significance for the future. Hopefully, this information will be useful to others as they embark on their journeys to purchase, deploy, or enhance their own HD Wi-Fi networks.

In the beginning: All about overhead

These are NOT paid advertisements, or infomercials. See our explanation of the feature to understand how it works.


Designers of first generation of HD Wi-Fi networks were starting to develop the basic concepts that would come to define HD deployments in large, open environments. Their work was informed by prior deployments in auditoriums and convention centers and focused on using directional antennas. The stated goal of this approach was to reduce co-channel interference [2] by reducing the effective footprint of an individual access point’s [3] RF output.

However the greatest gains came from improving the quality of the link between clients and the access point. Better antennas allowed client devices to communicate at faster speeds which decreased the amount of time required to complete their communication, making room for more clients on each channel before a given channel became saturated or unstable.

The concept was simple, but limited by the fact that there were few antennas available that could do the job effectively. Creative technicians created hybrid assemblies that combined multiple antennas into arrays that rotated polarization and tightened the antenna beam to paint the smallest usable coverage pattern possible. In time, this gap was addressed and today there are antennas specifically developed for use in overhead HD deployments – Stadium Antennas.

Typically, Stadium Antennas are installed in the ceilings above seating and/or on the walls behind seating because those locations are relatively easy to cable and minimize cost. We categorize these deployments as Overhead Deployments.

From overhead to ‘front and back’

First generation overhead deployments generally suffer from a lack of overhead mounting locations to produce sufficient coverage across the entire venue. In football stadiums, the front rows of the lower bowl are typically not covered by an overhang that can be used for antenna placement.

These rows are often more than 100 feet from the nearest overhead mounting location. The result is that pure overhead deployments leave some of the most expensive seats in the venue with little or no coverage. Further, due to the length of these sections, antennas at the back of the section potentially service thousands of client devices [4].

As fans joined these networks, deployments quickly became over-loaded and generated service complaints for venue owners. The solution was simple — add antennas at the front of long sections to reduce the total client load on the access points at the back. It was an effective band-aid that prioritized serving the venues’ most important and often most demanding guests.

This approach increased the complexity of installation as it was often difficult to cable access points located at the front of a section.

And for the first time, antennas were placed where they were subject to damage by fans, direct exposure to weather, and pressure washing [5]. With increased complexity, came increased costs as measured by the average cost per installed access point across a venue.

Because these systems feature antennas at the front and rear of each seating section, we refer to these deployments as ‘Front-to-Back Deployments.’ While this approach solves specific problems, it is not a complete solution in larger venues.

‘Filling In’ the gaps

Data collected from Front-to-Back Deployments proved to designers that moving the antennas closer to end users:
— covered areas that were previously uncovered;
— increased average data rates throughout the bowl;
— used the available spectrum more effectively; and
— increased total system capacity.

The logical conclusion was that additional antennas installed between the front and rear antennas would further increase system capacity. In long sections these additional antennas would also provide coverage to fans that were seated too far forward of antennas at the rear of the section and too far back from antennas at the front of the section. The result was uniform coverage throughout the venue.

In response, system designers experimented with hand rail mounted access points. Using directional antennas, coverage could be directed across a section and in opposition to the forward-facing antennas at the rear of the section and rear-facing antennas at the front of a section. These placements filled in the gaps in a Front-to-Back Deployment, hence the name ‘In-Fill Deployment.’

While these new In-Fill Deployments did their job, they added expense to what was already an expensive endeavor. Mounting access points on handrails required that a hole be drilled in the stadia at each access point location to cable the installed equipment. With the access point and antenna now firmly embedded in the seating, devices were also exposed to more traffic and abuse. Creative integrators came to the table with hardened systems to protect the equipment – handrail enclosures. New costs included: using ground-penetrating radar to prepare for coring; enclosure fabrication costs; and more complex conduit and pathway considerations. A typical handrail placement could cost four times the cost of a typical overhead placement and a designer might call for 2 or 3 handrail placements for every overhead placement.

Getting closer, better, faster: Proximate Networks

In-Fill strategies substantially solved the coverage problem in large venues. Using a combination of back of section, front of section, and hand-rail mounted access points, wireless designers had a tool box to deliver full coverage.

But with that success came a new problem. As fans discovered these high density networks and found new uses for them, demands on those networks grew rapidly, especially where teams or venue owners pushed mobile-device content strategies that added to the network load. In-spite of well placed access points, fan devices did not attach to the in-fill devices at the same rate that they attached to the overhead placements [6]. In-fill equipment remained lightly used and overhead placements absorbed hundreds of clients. Gains in system capacity stalled.

To overcome uneven system loading, designers needed to create a more even distribution of RF energy within the deployment. That required a consistent approach to deployment, rather than a mix of deployment approaches. The result was the elimination of overhead antennas in favor of access points and antennas installed within the crowd, closest to the end use; hence the name ‘Proximate Networks.’

Proximate networks come in two variations: handrail only and under seat only. In the hand rail only model, the designer eliminates overhead and front of section placements in favor of a dense deployment of hand rail enclosures. In the under seat model, the designer places the access point and antenna underneath the actual seating (but above the steel or concrete decking). In both models, the crowd becomes an important part of the design. The crowd attenuates the signal as it passes through their bodies resulting in consistent signal degradation and even distribution of RF energy throughout the seating bowl. The result is even access point loading and increased system capacity.

An additional benefit of embedding the access points in the crowd is that the crowd effectively constrains the output of the access point much as a wall constrains the output of an access point in a typical building. Each radio therefore hears fewer of its neighbors, allowing each channel to be re-used more effectively. And because the crowd provides an effective mechanism for controlling the spread of RF energy, the radios can be operated at higher power levels which improves the link between the access point and the fan’s device. The result is more uniform system loading, higher average data rates, increased channel re-ue, and increases in total system capacity.

While Proximate Networks are still a relatively new concept, the early data (and a rapid number of fast followers) confirms that if you want the densest possible network with the largest possible capacity, then a Proximate Network is what you need.

The Financials: picking what’s right for you

From the foregoing essay, you might conclude that the author’s recommendation is to deploy a Proximate Network. However, that is not necessarily the case. If you want the densest possible network with the largest possible capacity, then a Proximate Network is a good choice. But there are merits to each approach described and a cost benefit analysis should be performed before a deployment approach is selected.

For many venues, Overhead Deployments remain the most cost effective way to provide coverage. For many smaller venues and in venues where system utilization is expected to be low, an Overhead deployment can be ideal.

Front-to-Back deployments work well in venues where system utilization is low and the available overhead mounting assets can’t cover all areas. The goal of these deployments is ensuring usable coverage, not maximizing total system capacity.

In-fill deployments are a good compromise between a coverage-centric high density approach and a capacity-centric approach. This approach is best suited to venues that need more total system capacity, but have budget constraints the prevent selecting a Proximate approach.

Proximate deployments provide the maximum possible wireless density for venues where connectivity is considered to be a critical part of the venue experience.

Conclusion

If your venue is contemplating deploying a high density network, ask your integrator to walk you through the expected system demand, the calculation of system capacity for each approach, and finally the cost of each approach. Make sure you understand their assumptions. Then, select the deployment model that meets your business requirements — there is no “one size fits all” when it comes to stadium Wi-Fi.

Bill Anderson has been involved in the design and construction of wireless networks for over 20 years, pre-dating Wi-Fi. His first experience with wireless networking was as a software developer building software for mobile computers communicating over 400 MHz and 900 MHz base stations developed by Aironet (now part of Cisco Systems).

His work with mobile computing and wireless networks in distribution and manufacturing afforded him a front row seat to the emergence of Wi-Fi and the transformation of Wi-Fi from a niche technology to a business critical system. Since 2011 at AmpThink Bill has been actively involved in constructing some of the largest single venue wireless networks in the world.

Footnotes

^ 1. A proxy for the calculation of overall system capacity is developed by multiplying the average speed of communication of all clients on a channel (avg data rate or speed) by the number of channels deployed in the system (available spectrum) by the number of times we can use each channel (channel re-use) or [speed x spectrum x re-use]. While there are many other parameters that come into play when designing a high density network (noise, attenuation, reflection, etc.), this simple equation helps us understand how we approach building networks that can support a large number of connected devices in an open environment, e.g. the bowl of a stadium or arena.

^ 2. Co-channel interference refers to a scenario where multiple access points are attepting to communicate with client devices using the same channel. If a client or access point hears competing communication on the channel they are attempting to use, they must wait until that communication is complete before they can send their message.

^ 3. Access Point is the term used in the Wi-Fi industry to describe the network endpoint that client devices communicate with over the air. Other terms used include radio, AP, or WAP. In most cases, each access point is equipped with 2 or more physical radios that communicate on one of two bands – 2.4 GHz or 5 GHz. HD Wi-Fi deployments are composed of several hundred to over 1,000 access points connected to a robust wired network that funnels guest traffic to and from the internet.

^ 4. While there is no hard and fast rule, most industry experts agree that a single access point can service between 50 and 100 client devices.

^ 5. Venues often use pressure washers to clean a stadium after a big event.

^ 6. Unlike cellular systems which can dictate which mobile device attaches to each network node, at what speed, and when they can communicate, Wi-Fi relies on the mobile device to make the same decisions. When presented with a handrail access point and an overhead access point, mobile devices often hear the overhead placement better and therefore prefer the overhead placement. In In-Fill deployments, this often results in a disproportionate number of client devices selecting overhead placements. The problem can be managed by lowering the power level on the overhead access point at the expense of degrading the experience of the devices that the designer intended to attach to the overhead access point.

Analysis: The year of the big stadium Wi-Fi upgrade

Even in the midst of several brand-new stadium debuts and the future-proofed wireless networks inside them, there is a separate, yet distinct trend emerging in the big-stadium, wireless connectivity world: Call it the year of the big upgrade.

Our profile in our latest STADIUM TECH REPORT of Bank of America Stadium in Charlotte, N.C., is a case in point: Thanks to the never-ending demand for more connectivity for fans, stadiums that deployed networks just a few years ago are now finding that those old systems already need upgrades or replacements, typically at a much higher cost than the original network. In addition to BofA Stadium, the New England Patriots’ home, Gillette Stadium, also got a Wi-Fi makeover this past summer, going from about 400 Wi-Fi APs to well over a thousand, with most of the new ones deployed under seats.

According to Fred Kirsch, who oversees the Gillette Stadium network, some of the under-seat placements there were especially tricky, since granite underneath the stands didn’t allow for the ability to drill through the concrete. A workaround involving an above-ground enclosure was envisioned and manufactured, underlining the custom complexity of network deployment found from stadium to stadium. No two are the same, and what works at one may or may not work at another.

But what is common across all these large venues is the ever-increasing need for bandwidth, a moving target that has yet to slow down or stabilize. Last year the story that turned everyone’s head was the need by carriers to upgrade their DAS infrastructure at Levi’s Stadium ahead of Super Bowl 50 – this coming just a year after the stadium had opened for business. While the demands of a Super Bowl (especially Super Bowl 50, which set records for DAS and Wi-Fi usage) are perhaps much different than everyday events, it’s still a safe bet that for many stadiums with Wi-Fi networks – especially the early movers – 2016 has become a year of reckoning, or biting the bullet and writing more checks for more coverage, perhaps seemingly too soon after the initial rollout.

Getting ready for Super Bowl LI

In Houston, NRG Stadium finally has Wi-Fi, and not a moment too soon, with Super Bowl LI on the near horizon. Since the venue didn’t have Wi-Fi prior to this season it’s not really an upgrade but it’s hard to understate the challenge of putting in a Super Bowl-ready network in just one summer, a construction calendar shortened by the fact that integrator 5 Bars and equipment vendor Extreme Networks had to wait until after the NCAA Men’s Final Four was over to begin installing cabling and APs. At of the start of the NFL season the Wi-Fi network is already live at NRG Stadium, and is sure to go through weekly tweaks as the league marches on toward its championship game.

And while attention-grabbing new stadiums like US Bank Stadium in Minneapolis and Mercedes-Benz Stadium in Atlanta are planning big network capacity from the get-go, some new stadiums like T-Mobile Arena in Las Vegas have upgrade thinking planned in from the start, with the idea that the network will never really be a finished product, at least until they stop making new phones or developing new apps. Of course, that future isn’t happening anytime soon, with the Apple iPhone 7 announcement with the new double-lens camera coming in just before the start of another football season.

New phones and new apps mean more bandwidth demands, leading even those who already have stadium networks to keep wondering if what they’ve installed is enough. We suspect this may be an ongoing story line for the foreseeable future, so – stay tuned here to Mobile Sports Report for the latest success stories and lessons learned from those who have already jumped in or jumped back in to the deployment fray.

As part of the Wi-Fi and cellular usage records set at Super Bowl 50, fans at Levi’s Stadium also set new records for usage of the main stadium app features, including overall app adoption, viewing of action replays and Super Bowl commercials, and food and drink ordering.

According to the San Francisco 49ers networking staff, 46 percent of the 71,088 fans at the game downloaded the Super Bowl 50 stadium app, an NFL-specific app built by VenueNext, designers of the regular Levi’s Stadium app. That total is 16 percentage points higher than any recorded at a San Francisco 49ers regular-season game, according to the Niners.

One of the more unique features of the Super Bowl app was the ability for fans to use the app to order food and drinks, either for express window pickup, or for drinks only, the option for in-seat delivery. According to the Niners there were 3,284 food and beverage orders, 67 percent higher than the previous top order number ever recorded at a Levi’s Stadium game.

The Niners did not provide separate statistics for how many orders were for express pickup and how many were for in-seat delivery out of the larger total. Unlike the regular-season Levi’s Stadium app, which supports food and beverage delivery service to every seat, the Super Bowl app only offered drink delivery, per the wishes of the NFL.

According to VenueNext and the team, the average in-seat delivery time for drinks was 10 minutes. The top drink item ordered was Bud Light beer, while the top food item ordered via the app was chicken tenders, VenueNext said.

The Super Bowl 50 crowd also set Levi’s Stadium app records for video viewing, a stat helped perhaps by the availability of Super Bowl broadcast commercials, which fans at the game could watch via the app after they aired on TV. A full 55 percent of all app users either watched a video replay or Super Bowl commercials, the Niners said, 36 percent higher than the previous Levi’s Stadium record for video app views.

The app’s unique wayfinding feature, which uses the 2,000 beacons inside Levi’s Stadium to provide interactive maps, was used by 33 percent of the app users, according to the Niners. Fans could also use the app to purchase Super Bowl merchandise (which could be picked up at a concession stand or delivered to a suite), and according to the Niners all the mobile inventory was sold out before the game actually started, with an average order price of $212. Previously, the high-water average mark for app-ordered merchandise was $77 at a concert.

UPDATE: Top 4 carriers combine for 15.9 TB of cellular data use at Super Bowl 50

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.

Niners: All (tech) systems go at Levi’s Stadium for Super Bowl 50

As far as the technology at Levi’s Stadium is concerned, it’s all systems go for Sunday’s Super Bowl 50, according to San Francisco 49ers chief operating officer Al Guido.

In a phone interview with Mobile Sports Report, Guido said the 2-year-old stadium’s vaunted technology underpinnings — especially the wireless connectivity for fans — is ready to go for the NFL’s biggest yearly event, after a second season spent mainly fine-tuning the different components.

“We couldn’t feel more confident, hosting the game,” said Guido, speaking specifically about the technology infrastructure at Levi’s Stadium. As he stated before the regular season began, the Niners didn’t do anything radical to the stadium’s Wi-Fi network, which uses gear from Aruba, an HP Enterprise company, to bring the main wireless bandwidth to fans.

And while the stadium’s distributed antenna system (DAS) got a complete replacement over the summer, the new capabilities including under-seat DAS antennas for Verizon Wireless should only lead to better reception than the year before. According to Guido, representatives from Aruba as well as from “all the carriers” will be on hand Super Sunday just in case anything needs close attention.

“Everybody’s going to be at a high tech [support] level” on game day, Guido said.

No food, but in-seat beverage delivery as part of stadium app

The Super Bowl 50 stadium app, designed for the NFL by the Niners’ in-house app development company VenueNext, will have some but not all of the features Niners fans have available during the regular season. The most obvious omission is the lack of food delivery to all seats, something that makes Levi’s Stadium stand apart from any other large public sporting venue. Instead, the stadium app will only allow fans to order beverages for in-seat delivery, with the option to order food, beverage and merchandise that can be claimed at “express pickup” concession windows.

According to Guido, the decision to only have beverage deliveries at Super Bowl 50 was one reached jointly by the NFL, the Niners and VenueNext, and the catering company for the stadium, Centerplate. Guido said that the potential “amount of education” for all the fans new to the stadium and new to the app led the league, the Niners and the caterers toward a path of greater simplicity, namely just having beverages available for in-seat delivery.

“It was a risk-reward decision about the amount of fan education needed,” Guido said. “There’s so much going on at a Super Bowl and so many people new to the stadium that it didn’t seem worth it to us to risk someone not getting an order delivered because of their error, or our error.” Guido added that with all the extra breaks in action for a Super Bowl, and additional concessions stands, “there’s enough time to get around” to get food.

Michelle McKenna-Doyle, senior vice president and chief information officer for the NFL, told Sports Business Journal that the league was also concerned about game-day delivery traffic patterns being disrupted by the new media towers that have been built for the game in the corner plaza areas of the stadium. “We were worried about having to keep up with demand … and we need to keep the aisles clear, which is important to the security team,” McKenna-Doyle said in a story by SBJ’s Don Muret.

The app will, however, include its normal live wayfinding capabilities, which should prove useful to new visitors to Levi’s Stadium since they can watch themselves walk through a map of the facility as a familiar moving blue dot. Like it does for Niners games, the app will also have instant replays from multiple camera angles available, as well as Super Bowl extras like a “celebrity cam” and the ability to watch Super Bowl commercials right after they are broadcast on TV.

Guido said the Levi’s Stadium app performed well all season, with an average of about “2,000 to 2,500” in-seat delivery orders per game. What was especially pleasing to the team was the number of fans who used the app’s ability to support digital ticketing, a feature that makes life somewhat simpler for fans but exponentially better for the team, which can gain valuable marketing insight from digital ticket-use statistics. According to Guido almost 35 percent of fans used digital ticketing during the past season.

Media towers save seats for fans

Niners fans watching Sunday’s game on TV might be surprised by the media towers, which Guido said were built in the Intel and Dignity Health concourse areas, which during regular-season games are simply open spaces. Guido said the decision to build temporary facilities for media means that the regular stadium seats will be saved for fans. At many other pro championship or playoff events, the overflow media are often housed in regular seating areas.

“The NFL made a great decision there” to put the media in the pavilions, Guido said.

If there is one thing that can’t really be controlled, it’s the traffic and transportation issues of bringing fans to the game. On Sunday fans coming to the game will confront Levi’s Stadium’s unique location in the middle of many Silicon Valley corporate headquarters buildings, which presents challenges that stadiums like AT&T Stadium in Dallas or the University of Phoenix Stadium in Glendale, Ariz. — which are surrounded by acres of stadium-controlled parking lots — simply don’t have. To help with Super Bowl traffic the planners are using multiple methods, including using Google employee buses as shuttles as well as signing Uber as a sponsor with its own dedicated pickup and dropoff lot. There is also light rail service which stops right outside the stadium, which intially in the past experienced lengthy delays especially after games, but has improved over time.

“Traffic and transportation is our largest concern,” Guido said.

During their team’s exciting 20-18 victory over the New England Patriots Sunday, Denver Broncos fans who are Verizon Wireless customers used 2.87 terabytes of wireless data, according to Verizon. That total includes 1.7 TB used on the Verizon-only Wi-Fi network at Sports Authority Field at Mile High, and another 1.17 TB of data on the Verizon LTE DAS network at the stadium.

Also on Sunday, at the Bank of America Stadium in Charlotte, N.C., where the Carolina Panthers defeated the Arizona Cardinals, Verizon Wireless customers there used 1.3 TB of data on the Verizon LTE DAS network, according to figures sent to us by Verizon.

According to AT&T, its wireless customers set DAS traffic records at both stadiums Sunday, with 819 GB used on AT&T’s DAS network at Sports Authority Field and 739 GB used by AT&T DAS customers at Bank of America Stadium. Both totals are the highest-ever marks seen by AT&T at the respective stadiums, according to AT&T; the Denver total Sunday was 34 percent higher than the total used in the team’s first playoff game this season against Pittsburgh, and was 52 percent more than the average data used during regular-season games. In Charlotte, the DAS traffic total Sunday was 16 percent higher than the number hit during the playoff game a week previous against Seattle, and 50 percent higher than the average regular-season game, according to AT&T.

On the AT&T Wi-Fi network at Bank of America Stadium, fans used 740 GB of data, which AT&T said is also the highest-ever mark for that network, 19 percent higher than the previous playoff game vs. Seattle and 36 percent more than the network saw for average regular season games. The Wi-Fi network at Bank of America Stadium will be replaced this offseason, with a new network built by AmpThink and Aruba.

In Denver, the network situation is somewhat unique since Verizon built the Wi-Fi network inside Sports Authority Field at Mile High, but so far only Verizon customers are allowed access to it. While we’ll describe the situation in more detail in a stadium-visit profile coming very soon, the word from stadium IT types is that the Wi-Fi is open to other carriers but none have yet signed on to allow their customers access to it. There are, however, separate DAS networks for AT&T, Sprint and T-Mobile inside the stadium as well, so at least from a DAS perspective most fans at Mile High are pretty well connected.

Stay tuned for more soon on the networks at Sports Authority Field at Mile High! In the meantime, some pictures from our Jan. 3 visit below.
