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.
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.
