A deaf football team will debut a 5G-connected augmented reality helmet to call plays::The helmet, developed by AT&T and Gallaudet University, will debut at the school's Saturday game. When a coach chooses a play on a tablet, it will then display on a small lens on the player's helmet.

Why did they go with 5G? For the PR for AT&T? Seems like a shorter range less congested wavelength would work better, and potentially lower power too.

It's definitely marketing for AT&T

A big part of 5G is to support a lot more devices at the same time, making congestion a smaller issue.

5G, at least the fully developed version, which idk if they have here, supports directional beams, beamforming. That reduces any congestion to basically 0.

Like, I don't know the specifications here, but 5G would work fine, or possibly be better, than wi-fi. Wi-fi is designed for lower scales, and doesn't handle congestion as well, meanwhile mobile networks are designed to support mass amounts of devices simultaneously. 5G was designed with a lot of these future considerations in mind.

Edit: further, 5G uses a much shorter wavelength, or higher frequency. It can support far more theoretical traffic than wi-fi, and it has lower range to 4G due to higher attenuation, making congestion an even lower concern.

Yeah, 2.4GHz WiFi with a decently powerful transmitter would do great in this scenario. You'll have line of sight so you could likely cover the entire football field with one transmitter.

Uh oh.. Will conservatives scream that it's Satanic?

Doesn't the 5Gs spread COVID? I can't keep my conspiracies straight. /s

Gosh I hope so

No, because Bill Gates will have infected the 5G users with Demon AIDS by then, and the GOP won't need to worry about it.

The 5g radiation is going to turn the players into zombies, just like the zombies from the national alert /s
