Wifi jammer for drones

Drone Signal UAV 2.4GHz 5.8GHz Cheap Jammer

Drone brings us a lot of fun, but also destroyed our daily life. Ubiquitous noise harassment and spy camera, even weapons. More and more areas are using drone technology, but not everyone is using it in the right place. Some people might use the device to do something illegal

To catch drones, police and militaries are experimenting with everything from eagles to lasers. At the Davos Economic Forum, the answer is neither avian capture nor directed light: it’s radio frequencies generated by antennas and pointed at the drones.

In order to protect your daily life from being disturbed, we recommend that you use the drone jammer. This device can not only blocker with the general 2.4Ghz radio frequency, but also can jam the latest 5.8 Ghz radio frequency. This type of jammer’s block range up to 1500 meters, and even high-altitude UAV can be shot down.

After using the UAV jamming device, can be completely block within a certain range of UAV signals. You do not have to worry about personal privacy being spied, can enjoy the quiet time.

We have launched several new models of drone jammers on the website. The following are some of the better jammers. Both the interference range and the intensity are tested, so you can buy our products with confidence I believe our products will satisfy you

DIY Video Transmitter Turned WiFi Jammer

The proliferation of FPV drones has brought a flood of cheap wireless video tech. After flying and crashing a cheap FPV drone for a bit, [GreatScott] decided to try his hand at building his own video transmitter, which turned out to be a lot harder than expected.

While digital technology has caught up to the FPV world, a lot of systems still use analog video, especially for drone racing. The video quality isn’t great, but it has the advantage of very low latency. The technology is very similar to the old analog TV broadcasts, but mainly uses the 5.8 GHz license-free bands. It is essentially analog video signal, frequency modulated onto a 5.8 GHz carrier signal transmitted through an appropriately sized antenna.

After a brief failed experiment with a simple circuit built from discrete components, [GreatScott] turned his attention to voltage-controlled oscillators (VCO). He bought a couple of 5.8 GHz VCOs from Aliexpress, and created and used a simple opamp circuit to boost the FPV camera video signal to the required input level for the VCO. This failed to produce any identifiable image on his video receiver goggles. In an attempt to confirm that the VCOs produced the desired frequency, he ordered a similar 2.4 GHz VCOs and built a short range (20 cm) WiFi jammer. With a signal generator to create a simple input signal, and confirmed that it interfered with his laptop’s WiFi connection.

After more experimentation with other VCOs, the closest [GreatScott] came to success was a barely identifiable image transmitted using a Maxim 2.4 GHz VCO. If you have any ideas on what is missing in the VTX circuit, drop them in the comments below.

Building RF circuits that interfere with the legitimate signal around you, or broadcasting out of band, is generally not a great idea, and could earn you an unpleasant visit from the authorities. If you want to build your own digital video transmission, take a look at the Wifibroadcast project.

Last time I checked in on analog video it was Amplitude modulated. VCO sounds like voltage controlled frequency modulation. . . Audio was FM.

The C-band satellite TV signals were NTSC FM as well as the audio carriers. That’s why they had such good picture on a good TV.

Indeed. Actually analog video is modulated side banded to the right side of the carrier. The left side is suppressed. Audio was 4.5 Mhz higher in carrier frequency from the video carrier.

I went back to read the hobby king fine article.
One thing that has always peeved me off is when people are driving around staring at their phones. And then they get mad at me for smashing my horn when they almost hit me or someone else. Then they go right back to staring at their phone again… so i smash my horn again. There are various drop ship chinesium websites that will sell you various frequency jammers that are likely not legal without having a proper use case or exemption. But the thought has crossed my mind more than once of being able to smash a button and silently disconnect their phones rather than having my life and property put in peril. Makes me smile, but I would get in more legal trouble than they would for smashing into someone with their vehicle “on accident” when in fact their neglect and inability to focus on operating a machine is the real fault. In my experience, i have been in several accidents due to neglectful drivers and others not following proper use of the road, they get no legal penalty and I end up having to pay the cost due to the fact that insurance is a scam that never pays out without a more expensive lawyer. But then again for those people who are responsible, jamming would likely have them pick up their phone to look at it when their hands free call or podcast or music stops, potentially causing more havock than a single irresponsible driver.
Only tangentially related, but makes me think about every time someone wrecked my car or almost wrecked my car anytime i read about frequency interuption/jamming.
Also this:

The problem is that now most of these assholes are TEXTING instead of talking, which is harder to jam continuously (I think). And if you do, so what? They’ll just keep staring at the screen waiting for a reply (or keep typing, which doesn’t depend on reception anyway).

Never, under estimate, the predictability of stupidity. If you jam their signal. This will force the mobile user to demand a response from their mobile device, creating a digital dope fiend with banshee withdrawals episodes. Not to mention every user within range. Prepare to have your zombie kit on the ready. Be safe.
