@mark@metalhead.club LoRa can run on a range of frequencies within a band, and it supports frequency hopping too.

@mark@metalhead.club Yep there's LoRaWAN, which adds E2EE to LoRa.

Good example of LoRaWAN is The Things Network, the public LoRa Network that's run by volunteers who install their base stations.
