shokoishida Posted May 2, 2018 Share Posted May 2, 2018 I saw a very interesting discussion today. Using uav jammer and hacking techniques to control which is more effective. Personally, I think it is more effective to interfere with the frequency of uavs. How did your think? Quote Link to comment Share on other sites More sharing options...

Dave-ee Jones Posted May 3, 2018 Share Posted May 3, 2018 Yo whut?! $20k+ USD for a drone jammer.. How, in any world, is that worth to say "Ha, nice drone, kid. Shame it's been grounded!" (not that I would say that in the first place). I mean, if you really, REALLY wanted to make sure no one could see anything in a radius, including with drones, then maybe..

Forkish Posted May 3, 2018 Share Posted May 3, 2018 I’ve always known wifi to be 2.4 & 5ghz. it is really 5.8ghz used with drones or is wifi 5ghz and drones are 5.8ghz? if the same, wouldn’t a yagi and deauth be very similar to jamming? This much jam talk makes me want to watch Always Sunny in Philadelphia. Cat in the wall ‘eh?! Quote Link to comment Share on other sites More sharing options...
Dave-ee Jones Posted May 3, 2018 Share Posted May 3, 2018 When people say "5 GHz" they mean everything in the range of 5.1 -> 5.8 (specifically, for the US it's 5170-5835) for WLAN. That's why it's unspecified and rounded to 5 GHz. Most drones (and some RC cars) use 5.8 GHz, or 2.4 GHz. I assume it's for the range. We specify 2.4 GHz because it's only the 2400 MHz range that we use for WLAN. Not sure what they are exactly for Australia. 1 Quote Link to comment Share on other sites More sharing options...

There are some builds that can be found online for drone jammers in these ranges (mainly 5.8 GHz).

But hard to say for the linked devices since the specs aren't very in depth. Quote Link to comment Share on other sites More sharing options...

But then again, a lot of people prefer bacon so that may be the better option. Have to be a lot of bacon. A-lot of bacon. Just as a side note - you're Wigle widget is really bugging me. Shouldn't it say "SSIDs found: 434,812", not "WiFi Found: 434,812"? Seems English dodgy.. Quote Link to comment Share on other sites More sharing options...

But there are documented situations were a a ham radio operator is not doing an illegal act if operating within a frequency range and power level of a band, with a "broadcast signal stronger that another device" that causes a "jamming" type situation. I know this just sounds like a wording game but its more of a technical matter in the radio world. One good example is the use of OpenBTS to make a cell tower. There is nothing illegal about it on the right frequency and power levels allowed to amateur radio operators. It becomes illegal when it has malicious intent to force users to a tower used for eavesdropping, etc . Quote Link to comment Share on other sites More sharing options...

Also, once you find you're interfering with another device, you're supposed to fix the issue. Also, if you don't know you're doing it, the guys that show up in the black vans, will tell you... Usually with a fairly chunky fine. Quote Link to comment Share on other sites More sharing options...

Usually with a fairly chunky fine. I agree with what your saying. Just thought I would bring up that there are a few rare cases where it might actually be in the gray area. The black vans showing up would depend on how far and whose devices you ended up jamming. The even harder part to stay legal on "jamming" a drone is if it is using any sort of rolling code, encryption, frequency shift, etc. You aren't supposed to broadcast a signal with encryption except in some rare cases.

Forkish Posted May 5, 2018 Share Posted May 5, 2018 I don’t want to thread jack but I’m throwing this stuff in here because it seems to be a bustling thread with knowledgable people.. In the back of my mind, I’ve always wanted to get into short band radio stuff. Shit hits the fan kind of mentality. One of the networking apps I use is by a guy named Marcus Roskosch and he makes a bunch of really in depth Ham radio and electronic diagnostic/information type apps. Where’s a good place to start? Not spam but check out some of his stuff. maybe some one might find it useful: http://roskosch.de/marcus-roskosch/ HAM Radio Technician Exam preparation by Marcus Roskosch HAM Radio Technician Exam preparation by Marcus Roskosch HAM Radio Extra Exam preparation - FCC - ARRL by Marcus Roskosch HAM Radio General Exam preparation - FCC - ARRL by Marcus Roskosch RF-Toolbox Pro by Marcus Roskosch Electronic Toolbox Pro by Marcus Roskosch Home - Electronic Toolbox Quote Link to comment Share on other sites More sharing options...
