AT&T Is Using an Advanced Video Game Feature to Improve Your Phone Coverage

«Whatever Nvidia is doing for games, whatever Disney is doing … we are doing at a much bigger scale,» said AT&T’s Velin Kounev about using ray tracing to improve its network.

When you think of cellular networks, you probably envision radio towers and invisible data streams. But AT&T, by necessity, needs to see everything in between: buildings, trees and the multitude of obstacles that can interfere with wireless signals getting to your phone.

The cellular provider is turning to a key technology from gaming and computer graphics to get an accurate picture. AT&T Wireless Geo Modeler is a new system that uses ray tracing and AI to generate detailed representations of the areas covered by its network and improve connectivity. In doing so, AT&T says it can react to service interruptions quickly and also better predict how its network can be configured in response to large social events or during natural disasters.

How ray tracing works in a cellular context

In computer graphics, ray tracing is a technique for rendering three-dimensional scenes. Software simulates light beams emanating from a virtual camera and calculates how the light affects objects and materials in the scene. Ray tracing is notable for rendering shadows and reflections, leading to more realistic-looking environments.

In the past, ray tracing was computationally challenging. Early examples, such as the original Toy Story movie, required rooms full of processing hardware and up to 24 hours to render a single frame of footage. The graphics processor in high-end smartphones can now render photorealistic, ray-traced scenes in games in real time.

According to Velin Kounev, lead inventive scientist at AT&T Labs, the technology’s cellular application works the same way. «Whatever Nvidia is doing for games, whatever Disney is doing… we are doing at a much bigger scale,» he said.

In the context of AT&T’s Geo Modeler, Kounev explained, radio propagation from cellular towers is high-frequency light that our eyes cannot see. The towers measure how the rays react to the surrounding environment, such as colliding with structures or reflecting off surfaces. That collected data is processed and analyzed by several internal AT&T systems and machine learning models to determine if changes or optimizations need to be made, in what AT&T calls «near scale time.»

Those changes can include everyday adjustments to the angle of nearby antennas or compensating for a tower that has gone offline during a natural disaster. Modifications can be deployed automatically in seconds or minutes, ideally in a way that doesn’t impact customers.

«We don’t want [customers] to notice,» said Jennifer Yates, assistant vice president of inventive science, network and service automation at AT&T Labs. «The network is self-healing [and] autonomous behind the scenes so they don’t have to think about it.»

The benefit can also be a technical challenge that you would never notice as an AT&T subscriber. «When you hit Lincoln Tunnel traffic at 5 o’clock in the afternoon and you can get your website loaded, that’s when we come in,» said Kounev. «We’re optimizing the network traffic … in rush hour, where you’re able to get your connection.»

Predicting where to deploy resources

Although day-to-day network optimization is one advantage of using the Geo Modeler, it’s also a tool for determining how and where the company should deploy resources during situations such as weather events. For instance, if a prominent tree is blown over during a storm, ray tracing can quickly build a new representation of how towers should compensate.

For large events like music festivals, where tens of thousands of phones are accessing the network or impending natural disasters, the technology can be used to predict upcoming changes that are needed; Kounev mentioned Geo Modeler was applied in April at the Coachella festival.

Kounev also explained that if a hurricane is coming, for example, knowing its estimated size and timing, «we can go in and within two minutes remove [within the model] the towers that we think are going to be affected, and then see what the network coverage is going to look like.» Knowing where to expect holes in the network allows AT&T to position resources, such as generators or mobile cellular towers, in place before the hurricane strikes.

Most predictive tools, said Kounev, rely on existing measurement data. «Because we use ray tracing, we can predict in places where there’s no measurement data.»

AT&T has been building the Geo Modeler for a year and has accumulated enough data from different use cases over that time to be confident about deploying it more broadly. Yates said that AT&T has performed extensive validation of data, comparing the modeler’s results with measurements in the field.

«Over the last year,» said Kounev, «we had to convince people that this thing can actually work in real time with the many tower stations they have.»

Disney Exec Says ESPN Outage on YouTube TV May ‘Go for a Little While’

YouTube TV subscribers will miss college football on ESPN, ABC and conference networks for the third weekend straight.

More than two weeks after YouTube TV customers lost access to Disney’s streaming channels — including ABC, ESPN and the ACC and SEC networks — there is no sign of progress in the negotiations between the two entertainment giants.

At Disney’s fourth quarter earnings call on Thursday, Walt Disney CFO Hugh Johnston didn’t offer specifics on the ongoing negotiations, instead noting that «in terms of our (financial) guidance, we built a hedge into that (the YouTube TV outage), with the expectation that these discussions could go for a little while.»

Disney CEO Bob Iger ended the call on a more positive note, saying, «While we’ve been working tirelessly to close this deal and restore our channels to the platform, it’s also imperative that we make sure that we agree to a deal that reflects the value that we deliver.»

The disagreement causing the ABC and ESPN outage stems from the «carriage fee» that YouTube TV pays Disney to broadcast its channels. Disney has faced similar negotiating standoffs with other broadcasters in recent years, including an earlier 2021 outage on YouTube TV that was resolved in two days.

Disney says YouTube TV isn’t paying enough to stream its channels. YouTube TV, owned by Google, has the most subscribers among all internet TV providers, with over 9 million. Hulu, owned by Disney, is second with 4.3 million subscribers through its Hulu + Live TV offering.

«The deal that we have proposed is equal to or better than what other large distributors have already agreed to,» Iger also said Thursday.

While the two sides wrangle over the fees, they risk further losses. Nearly a quarter of YouTube TV subscribers (24%) have canceled or intend to cancel their subscription because the service «no longer delivers the core content they signed up for,» according to a survey cited by Variety.

Disney, meanwhile, is losing an estimated $30 million in revenue per week while its channels are unavailable on YouTube TV, according to a Morgan Stanley research note cited by Variety. That’s a significant chunk of change because each week Disney’s networks are dark on YouTube TV, Disney’s adjusted earnings per share drop by 2 cents, analysts say.

When will ESPN, ABC and other Disney channels return to YouTube TV?

Disney is no stranger to carriage fees feuds, and as with previous disputes, negotiations are under wraps, and how long it will continue is anyone’s guess. Disney’s contract conflict with Sling TV in 2022 lasted just two days, while the one with Spectrum/Charter in 2023 wasn’t resolved for 10 days.

Disney’s contract conflicts from previous years were mostly resolved in a week or two, but Google has considerably more bargaining power than those other platforms.

Thursday marked 14 days that Disney’s channels had been blacked out on YouTube TV — a day longer than the Disney outage on DirectTV last year. How much longer this outage will continue is unknown, but the Morgan Stanley analysts who pegged Disney’s weekly losses at $30 million sounded an optimistic note in predicting that the outage will be resolved later this week.

When a deal is reached between Disney and YouTube, the missing channels will return «in a matter of hours,» according to Variety.

What are Disney and YouTube TV saying about the dispute?

On Oct. 30, YouTube TV posted on X, «Members, when we renew our contracts with network partners, we advocate for fair pricing to offer you the best TV experience.»

«Google’s YouTube TV has chosen to deny its subscribers the content they value most by refusing to pay fair rates for our channels, including ESPN and ABC,» Disney said in a statement to CNBC.

In a memo to employees on Oct. 31 that was also reported by CNBC, Disney accused YouTube TV of deleting «previously recorded shows and events from their subscribers’ libraries.»

«YouTube TV and its owner, Google, are not interested in achieving a fair deal with us,» Disney Entertainment co-chairs Dana Walden and Alan Bergman and ESPN Chairman Jimmy Pitaro said in the memo. «Instead, they want to use their power and extraordinary resources to eliminate competition and devalue the very content that helped them build their service.»

Disney is also asking its viewers to ask YouTube TV to bring back its broadcasting via the keepmynetworks.com site.

Which Disney channels were removed from YouTube TV?

Sports fans aren’t the only viewers left sidelined by the loss of Disney channels from YouTube TV. Here are all the channels that have been removed from the streaming service:

ABC
ABC News Live
ACC Network
Baby TV Español (Spanish Plan)
Disney Channel

How can YouTube TV subscribers watch football games during the Disney outage?

YouTube TV subscribers with an aerial TV antenna can still watch Monday Night Football and college football games on ABC if they live close enough to receive an over-the-air broadcast signal from a local ABC affiliate.

Other than that, the only real option for viewers who want to watch all of the college football and basketball games this weekend and Monday Night Football at home is to subscribe to another service that provides ABC and ESPN, including ESPN+, Sling TV, Hulu + Live TV, Fubo or DirecTV Stream.

Sling TV offers a $5 Day Pass that could be a good option for viewers who want to watch one specific game, as well as a $10 Weekend Pass that would give you college football and basketball games for both days.

For those looking to find football games at local establishments, this handy app can help you find places that are showing the games.

YouTube TV has given $20 bill credits to subscribers

YouTube TV had promised subscribers a $20 credit for the streaming service if the Disney channels outage continued for an extended period, and on Sunday, the streaming service announced the details of that credit.

Some YouTube subscribers receive the $20 credit automatically, and others need to claim it online. According to a YouTube spokesperson, subscribers who pay with Google Play billing or through their mobile service should receive the $20 credit automatically.

If you need to claim the $20 credit, you should have received an email from YouTube TV. To redeem your the credit, follow these steps:

Log in to YouTube.com with a web browser
Click or tap on your profile picture
Click or tap Settings.
You can also directly browse to the URL at https://tv.youtube.com/settings/service_updates.
At the bottom of the menu on the left, select Updates.
On the following screen, which explains the Disney channels outage, click or tap the blue button marked Claim Credit.

Emails from YouTube TV started going out Sunday night and several Reddit posters have already reported receiving the $20 credit. All of the credits for YouTube TV subscribers should be issued by Wednesday, Nov. 12, according to Variety.

The $20 credit will be applied to your next billing cycle.

We asked YouTube TV if additional billing credits would be offered to subscribers if the outage continues. A spokesperson replied, «This is a situation that is evolving, and we will let subscribers know of future additional credit offers. Our main priority is to reach an agreement that restores Disney’s content to YouTube TV.»

Correction, Nov. 5: An earlier version of this story failed to note that Sling TV day and weekend passes can be used to watch local ABC affiliates only in certain markets.

Nintendo Says Newest Switch 2 Update Didn’t Deliberately Brick Third-Party Docks

Third-party dongle docks appear to be failing after the 21.0.0 update.

Nintendo released a new Switch 2 firmware update on Tuesday that came with a few albeit not significant changes to the portable console. It appears, however, this update might have bricked some third-party docks for the console in the process.

Switch 2 owners on social media say their third-party docks are no longer working with their systems after downloading firmware update 21.0.0, as first reported by Kotaku on Thursday. It’s unclear what in the firmware may have caused the issue, but it does appear that it primarily affects dock dongles, which plug directly into the Switch instead of the typical cradle-style docks that require the console to be placed in them.

Nintendo says it doesn’t have any intention to hinder or invalidate third-party docks.

«Nintendo Switch 2 outputs audio/visuals once it detects that it is docked into a Nintendo Switch 2 Dock. Nintendo Switch does the same, outputting audio/visuals once it detects that it is docked into a Nintendo Switch Dock,» the company said in an emailed statement to CNET.

What third-party Switch 2 docks are affected?

As of now, the only docks that appear to have issues are the third-party dongle docks. Standard docks and the official dock from Nintendo are fine.

Can these Switch 2 dock dongles be fixed?

It’s unclear if another Switch firmware update can address the problem. It’s also unlikely that the manufacturers of these docks will be able to provide a firmware update to address any problems.

This is not the first time third-party docks have had compatibility issues with a Switch console. In 2018, Nintendo released the 5.0.0 update for the original Switch, which not only caused some docks to stop working, it also led to consoles using those docks having problems. A 2019 report from Wired found that some third-party docks tried to emulate the same quick connections to the USB-C port on the Switch like with the official Nintendo dock. If the hardware has a slight manufacturing defect where the connections weren’t firmly connected, it could cause the USB-C power port on the Switch to fail.

Nintendo does advise Switch owners to use official Nintendo products for the system.

What else changed in the Switch 2 firmware update 21.0.0?

The latest Switch 2 firmware update went live on Tuesday and made a series of quality-of-life changes to the Switch 2, such as changing certain text in the settings to provide a better description of their functions; adding an option to cancel multiple software downloads at once; and adding icons on software to indicate whether it’s a physical or a digital version. This last change refers to the Game-Key Card feature for certain Switch 2 games that do not have the entire game on the cartridge and require downloading the game files.

Metroid Prime 4 for Switch 2 Delivers the Biggest Evolution the Franchise Has Seen

The next chapter in the Metroid saga lands in December with a major shift for the series. Here’s everything we know.

Metroid Prime 4: Beyond seemed like it would never come out since it was first teased in 2017, but the newest adventure featuring Samus Aran is less than a month away. Nintendo released a trailer Friday that highlights the biggest changes coming to the series.

In Metroid Prime 4, Samus responds to a distress call from the Galactic Federation, which is under attack by a bounty hunter known as Sylux. A disaster happens, transporting her to the planet Viewros, and now she has to use her new psychic powers and some help from allies to survive the planet in order to find her way home.

Metroid Prime 4: Beyond Trailer

When does Metroid Prime 4 come out?

Metroid Prime 4 will be released on Dec. 4.

What consoles will Metroid Prime 4 be released on?

Metroid Prime 4 will be available for the original Switch for $60 and on the Switch 2 for $70. For those with the original Switch now, but who think they might get a Switch 2 for the holidays, the Switch version can be upgraded to the Switch 2 version for $10.

What’s new in Metroid Prime 4?

The biggest change in Metroid Prime 4 is the open world. Previous Metroid Prime games usually confined Samus to caverns, temples or a ship, but this time around, she’ll be able to explore the world of Viewros. To help her traverse across the world, Samus can ride her bike called Vi-O-La.

Samus is known for her arsenal of powerful weapons, but in Metroid Prime 4, she will have new psychic abilities. These abilities will let her manipulate energy and activate machinery with just her mind.

Scattered across Viewros are Galactic Federation troopers, whom Samus will rescue but also fight alongside. This marks one of the few times when Samus isn’t battling alien forces on her own.

Will the Switch 2 version have any unique features?

A new feature only available with the Switch 2 version of the game is mouse controls. Players can use a Joy-Con 2 as a mouse by placing it on a hard surface, which some gamers insist is the proper way to play FPS games. If that isn’t of interest, both Metroid Prime 4 versions will make use of the Joy-Cons motion controls or a compatible gamepad, such as the Switch 2 Pro Controller.
