Some live demonstrations of wireless devices using spectrum in the Citizens Broadband Radio Service (CBRS) topped the venue-specific news at last week’s Mobile World Congress Americas trade show in Los Angeles.

At Angel Stadium in nearby Anaheim, a group of companies led by Connectivity Wireless and JMA teamed up to do some live demonstrations of use cases for the CBRS spectrum, a swath of 150 MHz in the 3.5 GHz range that uses the cellular LTE standard for device communications. One demo we heard about reportedly used a Motorola push-to-talk (PTT) handset to carry on a conversation from a suite behind home plate to centerfield, a “home run” distance of at least 400 feet.

Mobile Sports Report, which doesn’t often attend trade shows, found lots for venue technology professionals to be interested in at the show, including the live demonstrations of CBRS-connected devices in the JMA booth that included handsets, headsets and standalone digital displays using CBRS for back-end connectivity. MSR also sat down with Heidi Hemmer, Verizon’s vice president of technology, to talk about 5G for stadiums and why the push for the new cellular standard doesn’t mean the end of Wi-Fi. Read on for highlights of our visit to LA, which also included an interview with Boingo’s new CEO Mike Finley and with Paul Challoner, a CBRS expert at Ericsson.

Look at me, I can hear… centerfield

MSR wasn’t able to make it to the press event held at Angel Stadium, but we heard from multiple sources that the trial CBRS network installed there for a short stint in October by Connectivity Wireless and JMA performed as advertised, especially with the aforementioned full-field PTT talk between two devices, with one of those more than 400 feet away from the CBRS radio.

The worth of the ability for a device to communicate to a access-point radio at such a distance should be clearly apparent to venue wireless professionals, who may want to tap into CBRS networks to increase connectivity inside their venues. With more powerful radios than Wi-Fi and connectivity that utilizes the mobility and security of the LTE standard, teams and venues may look to CBRS for back-of-house communications that would benefit from being separated from the shared Wi-Fi infrastructures. While we are still waiting for the first publicly announced contract win for CBRS in venues — even the Angels are still weighing the decision to go forward with a CBRS deal — being able to show networks working live is a big step forward in the “is it real” phase.

Connecting digital displays, and more PTT

If there was a true “hot spot” for CBRS activity on the MWC show floor, it was at the JMA booth, where the wireless infrastructure company was running a live CBRS network with all kinds of devices running off it. JMA, which was showing its own CBRS radio cell (a kind of access point-on-steroids radio that will provide connectivity to client devices in a CBRS network) as well as a version of its XRAN virtual network core software, had a working prototype of one of the first commercially announced CBRS networks, a wireless deployment of digital displays for the parking lots at the American Dream shopping mall in New Jersey.

According to JMA director of markets and solutions Kurt Jacobs, the 600-acre parking lot at the huge new mall near the Meadowlands (it will have an amusement park and an indoor skiing slope, among other attractions and stores) was a perfect place to harness the ability of CBRS networks. The displays, large LED signs that can change dynamically to assist with parking instructions and directions, needed wireless connectivity to provide the back-end information.

But after considering a traditional deployment with fiber backhaul and Wi-Fi — which Jacobs said would have cost the mall at least $3 million to deploy with construction taking 6 months or more — the mall turned to JMA and a CBRS network deployment, which Jacobs said will use nine radios and 13 antennas to cover the signs, which will be spread out at key traffic junctions. Total cost? About a half-million dollars. Total deployment time? About eight weeks, according to Jacobs. Jacobs said the system will also eventually be able to support mobile CBRS radios inside security vehicles for real time updates from the lots.

Verizon to cover all NFL stadiums with 5G… and lots of Wi-Fi

Heidi Hemmer, Verizon

Heidi Hemmer, Verizon

MSR was fortunate enough to get on the appointment schedule of Heidi Hemmer, Verizon’s vice president of technology. A few days after Verizon had publicly announced a spate of 5G deployments in NBA arenas, Hemmer doubled down on the carrier’s 5G commitment to NFL stadiums, saying the current list of 13 stadiums with some kind of Verizon 5G coverage would soon expand to the entire league.

While hype is heavy around 5G — if you’re a football fan you’ve no doubt seen the Verizon TV commercial where Verizon’s technology development director Eric Nagy walks around various stadiums touting the service — Hemmer was clear that 5G is just part of a full-spectrum stadium wireless solution, one that will likely include 4G LTE as well as Wi-Fi well into the future.

While Verizon is clearly proud of its cutting-edge 5G deployments, the company is also probably the biggest provider of Wi-Fi networks in large stadiums, with many NFL and even some large colleges having Verizon-specific SSIDs for Verizon customers, usually as part of a sponsorship deal from Verizon. Verizon is also a big bankroller of distributed antenna system (DAS) deployments inside stadiums, sometimes acting as the neutral host and other times participating as a tenant on the in-venue cellular networks.

According to Hemmer, having as much connectivity as possible allows Verizon to provide the best possible experience for its customers. The eventual end goal, she said, would be a world where fans’ phones “dynamically” connect to whatever network is best suited for their needs, from Wi-Fi to 4G to 5G. Currently, many of the Verizon Wi-Fi deployments will automatically connect Verizon customers to Wi-Fi in a venue where they have previously logged on to the network.

And while the millimeter-wave 5G deployments inside stadiums right now don’t come close to covering the full space of any venue (at the Denver Broncos’ Empower Field at Mile High, for instance, there are only 16 5G antennas in the building), they do provide a different level of connectivity, with much faster download speeds and less latency. Hemmer said those characteristics could spawn an entirely new class of services for fans like better instant-replay video or advanced statistics. While MSR hasn’t personally tested any 5G networks, the early word is that in some situations download speeds can be in the gigabit-per-second range.

“Speeds are important to our customers and 5G can really push up the fan experience,” Hemmer said.

New Boingo CEO bullish on venues business

Mobile World Congress was also MSR’s first chance to meet Mike Finley, who became Boingo’s CEO back in February. A former Qualcomm executive, Finley said that Boingo’s history of being a neutral-host provider for venues should continue to drive more business in that realm, especially as newer complex possibilities like CBRS and Wi-Fi 6 networks emerge.

“We are satisfying a need” that venues have for connectivity expertise, Finley said, especially when it comes to relationships with wireless carriers.

At MWC, Boingo was part of the CBRS Alliance’s multi-partner booth space promoting the OnGo brand for CBRS gear and services. In its space Boingo was showing its new converged virtualized core offering (which was using JMA’s XRAN product) with a live combined CBRS and Wi-Fi 6 network running side by side. A booth representative with an iPhone 11 device was able to quickly switch between the two networks, offering a glimpse at the potential future networking choices venues may be able to offer.

Ericsson Dots target stadiums, CBRS

In its large MWC booth, connectivity gear provider Ericsson had a special display for venue equipment, including a weather-hardened version of its Radio Dot System that Ericsson booth reps said should be appearing soon in some U.S. sporting venues. Ericsson was also showing some Dots that it said would support CBRS, a service Ericsson sees great promise for in venues.

Paul Challoner, Ericsson’s vice president for network product solutions, said it will be interesting to see whether or not venues will need to pursue licenses for CBRS spectrum when those are auctioned off next year, or whether venues will choose to use the unlicensed parts of the CBRS spectrum. Like others at the show, Challoner was excited about Apple’s decision to include support for CBRS bands in the iPhone 11 line — “it’s a fantastic boost for the CBRS ecosystem,” he said.

There’s no baseball being played there now, but wireless traffic in the Citizens Broadband Radio Service (CBRS) spectrum is currently flying around Angel Stadium in Anaheim, Calif., part of a test being conducted by Connectivity Wireless and JMA for the Los Angeles Angels.

The trial network, which started operating on Oct. 14 and will run live through Oct. 25, is a proof-of-concept sort of demonstration by system integrator Connectivity Wireless and wireless gear supplier JMA, who have both targeted sports stadiums as one potential market for CBRS goods and services. CBRS is the acronym shorthand for a 150 MHz-wide swath of wireless spectrum at the 3.5 GHz range that can support communications using the LTE standard. With recent approval from the FCC for initial commercial deployments in CBRS, the Angels trial joins several other projects announced in mid-September.

As outlined in the diagram below provided to MSR by Connectivity Wireless, the CBRS trial will test several different use cases for the new bandwidth, including support for ticketing and concessions operations, connecting remote security cameras, powering digital displays, supporting push-to-talk voice communications, and also for general-purpose connectivity, in this case for back of house operations. As of yet, the Angels have not committed to buying a working CBRS network, but Connectivity Wireless has a history with the ballpark, as the company previously known as 5 Bars, later acquired by Connectivity Wireless, set up the Wi-Fi and DAS networks inside the venue.

The promise of CBRS airwaves is that they bring new, unshared chunks of spectrum into play — according to JMA and Connectivity Wireless, the JMA gear being used in the trial will allow for a number of dedicated 10 MHz lanes of traffic, each capable of 75 Mbps speeds. By supporting the cellular LTE standard for connectivity, CBRS also allows for fairly easy connectivity to a wide range of existing devices. Though some CBRS-specific dongles will be used to connect existing gear in the trial, a number of new devices — inlcuding Apple’s new iPhone 11 line — have added support for CBRS with new radios, a sign that CBRS already has significant backing even before any public commercial networks have been launched.

Though some parts of the CBRS equation still need to be completed, the clearance for initial commercial deployments and the fact that large real estate owners like sports venues can basically use the unlicensed parts of CBRS without paying licensing fees makes the spectrum attractive as a complement to existing Wi-Fi and cellular deployments. Though many sports venues, teams and leagues have shown interest in CBRS, the trial at Angels Stadium is the first public confirmation of any such tire-kicking.

The CBRS solution uses JMA’s XRAN software baseband and cell hub radio system, and according to Connectivity Wireless, other device partners were tapped to flesh out the CBRS trial, including Federated Wireless acting as Spectrum Access System (SAS) controller, along with Athonet’s Cloud Enhanced Packet Core (EPC) and Edge Node.

MSR will track the trial and see if we can get any results or reactions, so stay tuned! The CBRS season is just beginning.

Stadium Tech Report: Las Vegas Ballpark gets Major League Wi-Fi

The Las Vegas Ballpark has been a hit since its opening this year. Credit all photos: Paul Kapustka, MSR (click on any picture for a larger image)

Maybe for some late-night behavior, the old “What happens in Vegas stays in Vegas” rule still applies.

But when it comes to minor-league baseball, the tale of what’s happening at Las Vegas Ballpark is being spread far and wide, as the high-end finishes, fan-friendly amenities and high-definition Wi-Fi network at the new venue
are the talk not only of many Triple-A teams, but of other sports and possibly even Major League Baseball as well.

The $150 million ballpark, which opened this past season in the Vegas suburb of Summerlin, is the new shining jewel in minor-league baseball, with features like a huge video screen, party porches and club-level suites that feel more major-league than minor. So far the facility has been a smash hit with Vegas baseball fans, setting a new season-attendance record halfway through the summer and leading the minor leagues in attendance, despite the fact that the 10,000-seat venue is the seventh-smallest park in the PCL.

During a quick summer visit for a game at the park, Mobile Sports Report found that the fan-facing Wi-Fi network was at the same quality level as all the other amenities, with speed tests in the 60 Mbps range for both download and upload at most locations around the stadium. Built by Cox Business/Hospitality Network using Cisco gear, the network uses both under-seat and overhead AP deployments, as well as some on poles, to make sure all visitors have solid connectivity no matter where they roam inside the venue. With that kind of bandwidth, it’s no wonder that selfies, videos and other social-media reports are helping make Las Vegas Ballpark one of the worst-kept secrets in Vegas.

Major amenities for minor league park

“What’s happening here isn’t staying in Las Vegas,” said Branch Rickey, president of the Pacific Coast League, during an August press conference to announce that the 2020 Triple-A National Championship Game will be played at Las Vegas Ballpark on Sept. 22, 2020. Rickey, the grandson of the famous baseball executive with the same name, noted that the new facility is “resonating with players, coaches and executives” throughout the league.

While Las Vegas may have an outsized reputation for what happens with visitors to the legendary strip of casinos, the reality of the larger Las Vegas is that it’s like many other U.S. cities of a similar size, with families and residents who have been hungering for quality sports entertainment. The instant success of the NHL’s Las Vegas Golden Knights – who sold a ton of season tickets to locals – is reflected in the embrace of the Las Vegas Aviators’ new home, which is about as anti-Vegas as you can get.

Free parking, in a location far away from the Vegas Strip (Summerlin is about a 20-minute drive from the casinos at rush hour), and family-friendly features like a grassy hill beyond the right-field fence where kids can roll around – or ping-pong tables on an outfield patio for kids who can’t stay focused on baseball – make Las Vegas Ballpark a perfect place for families. And the more adult-focused sections, like the suites – or the party porches along each side of the stadium and the outfield swimming pool area, provide easy entertainment options for companies or other large groups looking to have a “team” event with baseball as a backdrop.

But in this day and age, no public sports place would seem complete without good wireless connectivity, and with its major-league Wi-Fi network, Las Vegas Ballpark covers that base completely. With 380 APs covering the entire park, MSR couldn’t find a single spot without consistent coverage, including even outside the entry gates.

According to Cox, approximately 130 of the APs are installed under seats, a trickier than usual deployment since the ballpark uses mesh seats in all seating areas – a construction that could dip fans’ bottoms closer to the APs than a regular hard plastic seat.

Mike Fredericks, vice president for IT development for stadium owners the Howard Hughes Corporation, said
the network was built to “major league standards,” and our unofficial speed tests seemed to confirm that quality. According to Cox, a 10 Gbps backbone powers the network. The Las Vegas Convention and Visitors Authority is the naming sponsor of the park, under an $80 million, 20-year deal.

As the technology sponsor, Cox Business/Hospitality Network is the exclusive solutions provider for the Las Vegas Ballpark, supporting both back-of-house networking as well as the fan-facing technology.

Solid Wi-Fi everywhere in the park

If there is one place that venues seem to consistently overlook when building out wireless, it’s the space just outside the ticketing gates toward the parking lot, an omission that can cause severe fan headaches in these days of increasing use of digital ticketing. There was no such problem at Las Vegas Ballpark, where outside the outfield (east) entryway we got a speed test of 51.5 Mbps on the download and 46.9 Mbps for upload. If there is one hitch to the free Wi-Fi it is the need to provide a name and a valid email address to log in, a registration process that seems to be generally falling out of favor in other stadiums.

Once inside the park MSR started a circumnavigation beginning with a path behind the centerfield wall, where we got a speed test of 57.1 Mbps / 58.6 Mbps. We walked directly underneath the 31-foot-high by 126-foot wide Daktronics video board, the largest in minor league baseball. We also walked directly underneath a MatSing ball cellular antenna, which Verizon is currently using to provide cellular coverage for its customers.

Until the DAS gets fully built out inside the stadium, AT&T, according to the stadium IT crew, plans to cover the stands using a macro tower on a nearby building; T-Mobile was providing service to the stadium using a COW (cell on wheels) unit in the main parking lot.

In both the left- and right-field corners of the stands, Las Vegas Ballpark has some “loge” type seating, with a fixed tabletop in front of several rows of seats. Under-seat Wi-Fi deployments on both sides seemed to work well, with speed tests of 65.6 Mbps / 68.9 Mbps in the left-field loge seats and 66.4 Mbps / 55.5 Mbps in right field. On the upper deck seating areas along both base lines are party decks, both of which were hosting private events on the night we attended; MSR was able to sneak in and get a speed test of 66.5 Mbps / 67.5 Mbps on the left-field deck; where Wi-Fi coverage was in part provided by a couple of APs mounted on a low pole.

We didn’t get a speed test at the centerfield pool area – another private party had the space reserved – but we did get a solid 43.8 Mbps / 57.3 Mbps mark at “The Hangar,” the centerfield bar. And even though the connectivity, architecture and trappings at the stadium had a major-league feel, the between-inning promotions – like kids racing on the field on bouncy blow-up horses – and local sponsors (like a land-surveying company for home-run distance measures) made sure the game kept the charm that only a minor-league game can provide.

At the press conference (held earlier in the day of our visit) executives from minor league baseball waxed eloquently about the park’s attributes. “This ballpark exceeded expectations, if that was possible,” said Pat O’Conner, president of Minor League Baseball. And while he stressed that he was no wireless expert, PCL’s Rickey did say that having major-league connectivity was an essential part of the minor league experience.

“If we are looking to find avenues to younger fans, we realize that they are very more connected,” said Rickey in a separate interview with MSR. “Our fans are reliant on their mobile devices, and they can be used to provide so much information about our game. Having great wireless is where we have to be. It’s essential to where we are headed.”

At Las Vegas Ballpark, that base is covered. Feel free to spread the word.

AT&T launching 5G-powered ‘fan experiences’ at AT&T Stadium for Cowboys opener

AT&T is launching what it calls ‘5G experiences’ for fans at AT&T Stadium on Sunday during the Dallas Cowboys’ NFL home opener, including some augmented-reality experiences that will let fans take selfies with huge-sized virtual NFL players or dodge virtual tacklers in an AR-type game.

While the 5G network powering the experiences inside the stadium won’t be open or available for general use, AT&T said it will have Samsung Galaxy S10 5G phones on hand in several places around the venue for fans to test out the applications that AT&T claims “couldn’t be done wirelessly at this level before 5G.” And even though 5G networks are still a long ways away from being a mainstream reality for most wireless customers, you can expect the largest U.S. carriers to fight a 5G marketing battle all fall around football stadiums, especially at NFL venues where NFL partner Verizon is already at work installing 5G test networks for use this season. In fact, Verizon also has a press announcement out today about having installed 5G services in 13 NFL stadiums. So get ready, wireless types, it’s 5G season.

Here at MSR we will try to keep our heads above any claims of stadiums being the “first” 5G-enabled or 5G-ready until such networks are prevalent and available for any and all visitors. That being said, the activations planned by AT&T for Sunday’s Cowboys home opener against the New York Giants sound kind of cool, so if any MSR readers are on hand for the game please do try them out and send us a field report or at least a selfie or two.

According to an AT&T press release, the 5G-powered experiences available at the game Sunday will include a thing called “Hype Up Chants,” where fans will be able to see a 36-foot tall version of Cowboys players Dak Prescott and Ezekial Elliott among others by viewing them through the camera of a provided Samsung phone. Fans will also be able to record their own end zone dance next to virtual teammates, over a provided 3-D video again powered by the 5G network and a Samsung phone.

On the stadium’s east side fans will be able to “pose with the pros,” again recording a virtual video with players like Elliott in what AT&T is calling an “immersive column,” a setup connected to the 5G network via a Netgear Nighthawk 5G mobile hotspot. And at the stadium’s club level, another set of Samsung phones will be available to show off live player and team stats in a broadcast-like AR format, while other fans will get to play a virtual football game where they will dodge “virtual defensive robots,” who may or may not be more effective than the real humans on the football field.

We have an email in to AT&T to find out more details if possible, including any other vendors involved in AT&T’s millimeter-wave 5G setup inside its namesake arena. Stay tuned for updates as they become available. Below are some renderings of how the experiences are supposed to look.

Closer Look: MatSing ball antenna deployment at Amalie Arena

Taking advantage of a cross-Florida drive, Mobile Sports Report finally got a live look at the MatSing ball antenna deployment at the Tampa Bay Lightning’s Amalie Arena, part of a new neutral-host DAS being built by AT&T. Some early returns on the MatSing ball network performance have gained a lot of attention, with rumors floating around this summer of multiple MatSing deployments either in the offing or already underway.

Since our visit was in the hockey offseason we didn’t get to test the DAS in action, but thanks to the hospitality of new Tampa IT director Andrew McIntyre (who recently left a similar position with the Chicago Cubs) we got to look around the arena at the MatSing deployment, which by AT&T’s count uses 52 of the distinctive round-ball antennas mounted in various places in the rafters.

We hope to return sometime this fall or winter to witness the network in action, but for now take a look at some of the peculiarities of the deployment, including the very specific angles for pointing the antennas toward very specific parts of the seating area.

What’s the buzz behind MatSings? Here is a bit of explanation from an earlier MSR story:

Why use MatSing antennas? What sets MatSing ball antennas (also called “Luneberg Lens” antennas) apart from other wireless gear is the MatSing ball’s ability to provide a signal that can stretch across greater distances while also being highly concentrated or focused. According to MatSing its antennas can reach client devices up to 240 feet away; for music festivals, that means a MatSing antenna could be placed at the rear or sides of large crowd areas to reach customer devices where it’s unpractical to locate permanent or other portable gear. By being able to focus its communications beams tightly, a MatSing ball antenna can concentrate its energy on serving a very precise swath of real estate, as opposed to regular antennas which typically offer much less precise ways of concentrating or focusing where antenna signals go.

What should bear watching in Tampa is the progression of the Water Street Tampa project, which includes Lightning owner Jeffrey Vinik and Microsoft’s Bill Gates as investors. Water Street, right outside the arena’s doors, is going to be yet another near-the-stadium downtown development area, though this one seems more ambitious than some of the stadium-centric plans around other new arena builds. We will of course keep track on how the wireless coverage goes from arena to outdoors. For now, enjoy some more close-ups of the MatSings:

Federated Wireless completes ESC network for CBRS

Federated Wireless announced Monday the completion of its environmental sensing capability (ESC) network, in what may be one of the final stepping stones toward commercial deployments of networks in the CBRS band.

Under the unique shared-spectrum licensing structure of the CBRS (Citizens Broadband Radio Service) band, a swath of 150 MHz in the 3.5 GHz range, an ESC network must be in place to sense when U.S. Navy ships are using the band. What Federated is announcing Monday is that its ESC network is ready to go, one of the final things needed before commercial customers of Federated’s products and services would be able to formally start operating their networks.

Though the Federated ESC network is still pending final FCC approval, Federated president and CEO Iyad Tarazi said in a phone interview that the company “expects to get the green light [from the FCC] in June,” with the commercial customer launches following soon behind. Federated, a pure-CBRS startup with $75 million in funding, also offers Spectrum Access Services (SAS), another part of the CBRS puzzle to help ensure that any network operators who want to play in the shared-space sandbox that is CBRS are only using spectrum chunks that are free of any higher-priority traffic.

According to Tarazi Federated already has 25 customers testing its gear and services in getting ready to launch CBRS networks, a yet-unnamed group of entities that Tarazi said includes wireless carriers, enterprise companies looking to launch private networks, and even some large public venues.

Private networks first for venues?

The early thinking on CBRS use cases for sports stadiums includes the possibility of using private LTE networks for sensitive internal operations like ticketing and concessions, or even for closed-system video streaming and push-to-talk voice support. In the longer-term future, CBRS has been touted as a potential way to provide a neutral-host network that could support fan-facing carrier offload much like a current distributed antenna system (DAS), but to get to that place will still likely require some more-advanced SIM technology to be developed and deployed in client devices like cellphones.

But the potential of a new, huge chunk of spectrum — and the possibility of teams, leagues and venues being able to own and operate their own networks — has created a wide range of interest in CBRS among sports operations. While many of those same entities already operate stadium Wi-Fi networks, CBRS’s support for the cellular LTE standard theoretically could support faster, more secure networks. However, the emerging Wi-Fi 6 standard may close the performance gaps between cellular and Wi-Fi in the near future; many networking observers now seem to agree that most venues will likely see a continued mix of Wi-Fi and cellular systems in the near future, possibly including CBRS.

Already, the PGA and NASCAR have live tests of CBRS networks underway, and the NFL and Verizon have kicked the ball around with CBRS tests, reportedly for possible sideline headset network use.

While CBRS will potentially get more interesting when the commercial deployments become public, if you’re a network geek you will be able to appreciate some of the work done by Federated to get its ESC network operational, starting with the deployments of sensors on coastal structures as varied as “biker bars and luxe beach resorts,” according to a Federated blog post.

Tarazi, who was most recently vice president of network development at Sprint, said the Federated ESC network is “triple redundant,” since losing just one sensor could render a big chunk of spectrum unusable.

“If you lose a sensor, you lose hundreds of square miles of [available] network,” Tarazi said. “That’s a big deal.”

And ensuring network availability is in part what Federated’s clients will be paying the company for, part of the puzzle that when put together will theoretically open up wireless spectrum at a much lower cost compared to purchasing licensed spectrum at auction. As one of the pick-and-shovel providers in the CBRS gold rush, Tarazi and Federated may be the only ESC game in town for a while, as the joint effort between CommScope and Google to build another ESC is not expected to be completed until later this year at the earliest.

“I feel like we’re at an inflection point now,” Tarazi said. “It feels good to be leading this wave.”
