I know you're joking but,..

Jamming wifi, with kali, and its Penetration testing tools, or jamming wifi with an, illegal, dedicated jamming device that kills every wireless connection within its radius?
Well, you wont be affected by Kali if a wifi-direct/bluetooth connection is used, because the chance that someone is sitting with their Kali-loaded-laptop/portable device, in your range, in your area, just waiting for you to start the communication, to start cracking a file transfer that will probably last a few seconds/minutes, at best, is a pretty unrealistic scenario.
And if someone around you is using a dedicated jamming device, to block every kind of wireless communication, you definetly have bigger things to worry about.

Of course, you might do an oldschool file transfer with an encrypted USB-Stick, in one of these



if you dont want to take any chances.


Chen might add it for retro-reasons, though.
