Really? Something that has a range of 30’ (9m) and use it for a fucking concert and use the same frequencies as 1000’s of atendees?
Bluetooth is a short range low bandwidth (at least vs wifi, 3/4/5g) protocol. Using it for something well outside its capablilites is stupid. Like taking a mini mudding or hammering in nails using a rachet
You hypothetical situation is just pointing out the very well known flaws of the bluetooth protocol. So once again, what a stupid line of questioning
