There is a technology called BLE, which together with mesh networking and synchronization of messages instead of routing them can give you connectivity in the middle of big events, without too much signal noise.
Of course other than Briar and that Bitchat thing I don't know what to use in such situations.
there's also MIMO, which lets one device relay a 5G signal for another. i don't think most people appreciate losing battery to route someone elses call though.
Yes, and I meant that BLE doesn't spread far. Which is good in such an environment.
you can get it to like 50m actually. not reliably, and absolutely not in that kind of environment, but it is possible.
