Is there a portable civilian device that allows for short to medium range (10 miles or so) that would allow for 128 or 256 bit encrypted data bursts, and if so, what level certification would one need to go about for using it legally in the US? I’m imagining a data burst to convey less than 1 MB of data with an accompanying bit total that could then be “delivery confirmed” by a return message with that bit total. Bonus points if it could play nicely with a Disco32 Discus.
I know it wouldn’t fool a foxhunt, but was curious if such a thing exists and if so, what’s the entry cost in money and time?
WiFi will need some big dish antennas and unobstructed line of sight to get that kind of range. Just be careful not to exceed the EIRP limits.
There is also 900MHz WiFi (802.11ah) for longer range, low speed use. The equipment is not very common though.
