I am currently working on a project where a Raspberry Pi will be used to run an nmap scan on a (purpose built) wireless network, and then attempt to exploit vulnerabilities found on the network.

The exploiting Raspberry Pi will be mounted on a drone, and often well outside the range of a WiFi network that might be used to remotely control the Raspberry Pi, but still with line of sight. Therefore, I need to send commands and receive back results, preferably in an SSH-like fashion, to the Raspberry Pi. I'm thinking I'd do this from another Raspberry Pi or some other Linux machine.

Due to range limitations, I'm thinking that an RF connection would be a decent solution. My question is, is it possible to have that kind of control via an RF transceiver connection, and if so, would such a connection need to be full duplex, or just half-duplex? If so, what hardware would work for this? I may already be using 868 MHz frequency (RFM95/LoRa) for controlling the drone.

Thanks for any and all help.

    "what hardware would work for this?" -> If you want to use IP based apps (eg. ssh), you need something that provides a network interface over USB.

You can enable the Pi's serial input via raspi-config and use the radio transceivers as a uart-radio-uart bridge. If you use different channels for up- and down-link (so that the channels do not interfere), everything would be exactly like if you controlled the Pi via its serial command line. The software wouldn't even care about how data is transmitted physically.
