Control systems for drones typically run on 2.4GHz, but they don't have to. The 70cm band (433MHz typical) is available for people with amateur radio licenses (or people who don't care). There are also 3G chips (Particle Electron) that you can use to send telemetry commands if your drone has a GPS and a compatible auto-pilot flight controller.

Getting a video signal back is normally done on 5.8GHz, but there is hardware readily available for 900MHz, 1.2GHz, 2.4GHz, and 3.3GHz. And if you're an enterprising fellow you can send the video on any frequency (NTSC or PAL).

Basically, you can't block it all without serious collateral "damage".

Edit: I've been building and flying drones for over two years, both FPV racing types and larger photography/videography platforms.

This is becoming a tad complicated and with a lots of steps involved for just bombing things isn't it? I mean Tony Stark could it in a cave, but could Joe Terrorist do it?

ps: I shouldn't talk about the costs effectiveness of terror bombing, but it doesnt' seem like something those guys would do, car bombing seem like a "good" enough approach in general.

As a constant follower of the /r/syriancivilwar sub-reddit for the last 2 and a half years all I can say is that one should never under-estimate the technical capabilities and know-how of the other side, be they religious fundamentalists like ISIS or tha AQ-affiliated factions from outside Aleppo and from the province of Idlib. Judging by the many videos of ISIS in action thag I've seen I can say that they were pretty quick in using and mastering drones for their military purposes, along with satellite maps and (I think custom-made) tablet apps.

I agree. It's the XXI century. There is Internet. Point any country on Earth, and you can bet you'll find there many software developers and electrical engineers, be it hobby or professional.
