GSMA transforms Formula E circuit into 5G testbed | Computer Weekly
With its flagship MWC exhibition about to open its doors in a matter of weeks, global mobile trade body the GSMA has announced a raft of technology partners for the CircuitX project for which it is a joint partner, and which aims to provide a practical blueprint for how interoperable connectivity can scale across smart venues and live events.
Established in March 2025, CircuitX comprises a three-year initiative designed to champion mobile technology across motorsports and transform the circuit experience with connectivity.
It is led by the GSMA’s innovation hub, GSMA Foundry; Fira Circuit, a company formed and managed by Fira de Barcelona to transform the Circuit de Barcelona-Catalunya into a centre for innovation and next-generation motorsport experiences; and Mobile World Capital, a public-private foundation that promotes the digital development of society.
CircuitX’s project will cover five core areas to highlight where mobile connectivity can support innovation across motorsport and large-scale events. This includes travel and navigation including real-time journey management and traffic optimisation; security and safety with enhanced emergency communication and crowd monitoring; fan movement based on smart venue navigation and crowd flow management; fan experience comprising personalised content, live data and immersive experiences; and race telemetry, with secure, efficient data transmission for teams and fans.
“CircuitX is more than a showcase; it’s a blueprint for the future of connected experiences,” said GSMA CEO John Hoffman. “By integrating mobile technology into motorsport and entertainment, GSMA and its partners aim to set new standards for safety, efficiency and fan engagement. This reinforces the pivotal role of mobile connectivity as a catalyst for ongoing innovation.”
A showcase demonstration at Circuit de Barcelona-Catalunya and MWC26 Barcelona, set for 1 March, is set to feature participation from leading motor racing teams and technology collaborators to showcase tele-driven vehicles, in-race telemetry, live broadcast, drone safety and security measures, as well as immersive augmented reality (AR) and virtual reality (VR) experiences for fans.
The showcase will feature leading partners showcasing what is described as advanced mobile technology and connectivity services, supported by Al Kamel, Semtech & Domo Broadcast Systems, Barcelona Drone Center, Elmo, Ericsson, Into Reality, MatSing, NTT Data, Prospeed, Telefónica and Formula E.
Formula E’s participation will encompass sustainability-driven racing innovations, integrating connectivity for enhanced telemetry and fan engagement. The Gen3 EVO Formula E race car demonstrates its capabilities on the track, able to accelerate from 0 to 60mph in just 1.82 seconds.
Joining the initiative as the official connectivity partner, Telefónica will provide 5G network coverage at both locations. IT services provider Al Kamel will show how ultra-low latency networks transform race operations, from instant incident detection and dynamic race strategies, and will also offer what it said was a glimpse into the future of precision motorsport management supported by Semtech and Domo Broadcast Systems.
Barcelona Drone Center will showcase its devices that see use in crowd monitoring, emergency response and perimeter security, using advanced Unmanned Aircraft System technology and regulatory expertise. These are regarded as critical for modern smart venues.
Ericsson will bring its private 5G technology to deliver a secure, high-performance network tailored to the device mobility demands of motorsport environments – essential for telemetry, video streaming and safety-critical systems, while Elmo will demonstrate real-time teledriving of vehicles over public 5G networks, including stable remote operation at higher driving speeds, enabled by network quality APIs that ensure low latency, reliability and service continuity for safety-critical vehicle control.
NTT Data will show AI-enabled applications, including services that enhance operations and safety, as well as mobile applications that leverage live data and AI-driven insights to deliver a digital-first fan experience both on- and off-site.

Onnit’s Instant Melatonin Spray Is the Easiest Part of My Nightly Routine
I’ve always approached taking melatonin supplements with skepticism. They seem to help every once in a while, but your brain is already making melatonin. Beyond that, I am not a fan of the sickly-sweet tablets, gummies, and other forms of melatonin I’ve come across. No one wants a bad taste in their mouth when they’re supposed to be drifting off to sleep.
This is where Onnit’s Instant Melatonin Spray comes in. Fellow WIRED reviewer Molly Higgins first gave it a go, and reported back favorably. This spray comes in two flavors, lavender and mint, and is sweetened with stevia. While I wouldn’t consider it a gourmet taste, I appreciate that it leans more into herbal components known for sleep and relaxation.
Keep in mind that melatonin is meant to be a sleep aid, not a cure-all. That being said, one serving of this spray has 3 milligrams of melatonin, which takes about six pumps to dispense. While 3 milligrams may not seem like a lot to really kickstart your circadian rhythm, it’s actually the ideal dosage to get your brain’s wind-down process kicked off. Some people can do more (but don’t go over 10 milligrams!), some less, but based on what experts have relayed to me, this is the preferable amount.
A couple of reminders for any supplement: consult your doctor if and when you want to incorporate anything, melatonin included, into your nighttime regimen. Your healthcare provider can help confirm that you’re not on any medications where adding a sleep aid or supplement wouldn’t feel as effective. Onnit’s Instant Melatonin Spray is International Genetically Modified Organism Evaluation and Notification certified (IGEN) to verify that it uses truly non-GMO ingredients.
Apart from that, there may be some trial and error on the ideal amount for you, and how much time it takes to kick in. Some may feel the melatonin sooner than others. For my colleague Molly, it took about an hour. Melatonin can’t do all the heavy lifting, so make sure you’re ready to go to bed when you take it, and that your sleep space is set up for sleep success, down to your mattress, sheets, and pillows.

I Tested Bosch’s New Vacuum Against Shark and Dyson. It Didn’t Beat Them
There’s a lever on the back for this compression mechanism that you manually press down and a separate button to open the dustbin at the bottom. You can use the compression lever when it’s both closed and open. It did help compress the hair and dust while I was vacuuming, helping me see if I had really filled the bin, though at a certain point it doesn’t compress much more. It was helpful to push debris out if needed too, versus the times I’ve had to stick my hand in both the Dyson and Shark to get the stuck hair and dust out. Dyson has this same feature on the Piston Animal V16, which is due out this year, so I’ll be curious to see which mechanism is better engineered.
Bendable Winner: Shark

If you’re looking for a vacuum that can bend to reach under furniture, I prefer the Shark to the Bosch. Both have a similar mechanism and feel, but the Bosch tended to push debris around when I was using it with an active bend, while the Shark managed to vacuum up debris I couldn’t get with the Bosch without lifting it and placing it on top of that particular debris (in this case, rogue cat kibble).
Accessory Winner: Dyson
Dyson pulls ahead because the Dyson Gen5 Detect comes with three attachments and two heads. You’ll get a Motorbar head, a Fluffy Optic head, a hair tool, a combination tool, and a dusting and crevice tool that’s actually built into the stick tube. I love that it’s built into the vacuum so that it’s one less separate attachment to carry around, and it makes me more likely to use it.
But Bosch does well in this area, too. You’ll get an upholstery nozzle, a furniture brush, and a crevice nozzle. It’s one more attachment than you’ll get with Shark, and Bosch also includes a wall mount that you can wire the charging cord into for storage and charging, and you can mount two attachments on it. But I will say, I like that Shark includes a simple tote bag to store the attachments in. The rest of my attachments are in plastic bags for each vacuum, and keeping track of attachments is the most annoying part of a cordless vacuum.
Build Winner: Tie

All three of these vacuums have a good build quality, but each one feels like it focuses on something different. Bosch feels the lightest of the three and stands up the easiest on its own, but all three do need something to lean against to stay upright. The Dyson is the worst at this; it also needs a ledge or table wedged under the canister, or it’ll roll forward and tip over. The Bosch has a sleek black look and a colorful LED screen that will show you a picture of carpet or hardwood depending on what mode it’s vacuuming in. The vacuum head itself feels like the lightest plastic of the bunch, though.

Right-Wing Gun Enthusiasts and Extremists Are Working Overtime to Justify Alex Pretti’s Killing
Brandon Herrera, a prominent gun influencer with over 4 million followers on YouTube, said in a video posted this week that while it was unfortunate that Pretti died, ultimately the fault was his own.
“Pretti didn’t deserve to die, but it also wasn’t just a baseless execution,” Herrera said, adding without evidence that Pretti’s purpose was to disrupt ICE operations. “If you’re interfering with arrests and things like that, that’s a crime. If you get in the fucking officer’s way, that will probably be escalated to physical force, whether it’s arresting you or just getting you the fuck out of the way, which then can lead to a tussle, which, if you’re armed, can lead to a fatal shooting.” He described the situation as “lawful but awful.”
Herrera was joined in the video by former police officer and fellow gun influencer Cody Garrett, known online as Donut Operator.
Both men took the opportunity to deride immigrants, with Herrera saying “every news outlet is going to jump onto this because it’s current thing and they’re going to ignore the 12 drunk drivers who killed you know, American citizens yesterday that were all illegals or H-1Bs or whatever.”
Herrera also referenced his “friend” Kyle Rittenhouse, who has become central to much of the debate about the shooting.
On August 25, 2020, Rittenhouse, who was 17 at the time, traveled from his home in Illinois to a protest in Kenosha, Wisconsin, brandishing an AR-15-style rifle, claiming he was there to protect local businesses. He killed two people and shot another in the arm that night.
Critics of ICE’s actions in Minneapolis quickly highlighted what they saw as the hypocrisy of the right’s defense of Rittenhouse and attacks on Pretti.
“Kyle Rittenhouse was a conservative hero for walking into a protest actually brandishing a weapon, but this guy who had a legal permit to carry and already had had his gun removed is to some people an instigator, when he was actually going to help a woman,” Jessica Tarlov, a Democratic strategist, said on Fox News this week.
Rittenhouse also waded into the debate, writing on X: “The correct way to approach law enforcement when armed,” above a picture of himself with his hands up in front of police after he killed two people. He added in another post that “ICE messed up.”
The claim that Pretti was to blame was repeated in private Facebook groups run by armed militias, according to data shared with WIRED by the Tech Transparency Project, as well as on extremist Telegram channels.
“I’m sorry for him and his family,” one member of a Facebook group called American Patriots wrote. “My question though, why did he go to these riots armed with a gun and extra magazines if he wasn’t planning on using them?”
Some extremist groups, such as the far-right Boogaloo movement, have been highly critical of the administration’s comments on being armed at a protest.
“To the ‘dont bring a gun to a protest’ crowd, fuck you,” one member of a private Boogaloo group wrote on Facebook this week. “To the fucking turn coats thinking disarming is the answer and dont think it would happen to you as well, fuck you. To the federal government who I’ve watched murder citizens just for saying no to them, fuck you. Shall not be infringed.”
