The reason radio is robust against disaster is because it's peer-to-peer, not because it's analogue.
So, a like-to-like alternative is probably a encrypted local mesh network.
- thfuran 7y agoAll our 'digital' signals are ultimately transmitted over some analog channel. "Digital" is an abstraction. There's no reason you can't encrypt a radio transmission without relying on intermediaries to relay it as in a mesh network.
- Aloha 7y agoYou can do encryption without mesh - the digital radio standards all support it.
- buildzr 7y agoTrunked radio systems, as used by police, firefighters and EMS worldwide are not peer-to-peer. You transmit to the trunk, it relays to people in your selected group. All radios rely on a control signal from the trunk for determining where to send and when to listen. https://en.wikipedia.org/wiki/Trunked_radio_system https://en.wikipedia.org/wiki/Trunked_radio_system
