The GPS Jammer - Does it work?
Вставка
- Опубліковано 2 лют 2023
- I was intrigued by this device I stumbled upon online, so I decided to take a chance and purchase one to put it to the test. Unfortunately, many of the devices showcased on the internet are falsely advertised or not manufactured with quality, so I was naturally skeptical. However, I was excited to give it a try and see if it could live up to its promises.

Volume is really low and this is a very interesting topic.
Thank you so much
good stuff
What is a natural gps jammer? Everything is vibration and frequency so ik there has to be one admitted naturally to could disrupt a signal
"Everything is vibration and frequency" is common in new age philosophies, but not really descriptive or useful in technology. There are piezoelectric resonators, which need to be cut to a specific physical size for a frequency. The bandwidth would be too narrow to cover an entire band. There is stimulated emission, but that is also very narrow and not tunable as it is characteristic of a specific element and the energy states of it's electrons. Either way requires a power source to generate a signal stronger than the incoming GPS signal, so no, you are not going to find a natural substance that jams GPS signals. You could block the signal with a faraday cage, but building one around your car would render the car undrivable. We have to go with science rather than mysticism here.
Nice demonstration. The reason it’s not working is not it doesn’t cover the appropriate band but because output power is very low. GPS has spread spectrum process gain so jammer has to be at least +50dBm above gps signal to have any effectiveness. With gps at -125dbm any jamming signal bellow -75dbm at gps receiver will have zero effectiveness. I ve seen jammer emitting 0dbm to only be effective up to 5 meters radius against a modern smartphone. So probably the device is poor quality/defective.
(YES THIS IS.. CRAP)
HAVE A JAMMER "SOME WATT OUT" IT RUNS A "LONG WAY"
LIKE A "VHF RADIO" ...
(AND NOT TO FORGET WHAT ANT ... YOU USE)
NEXT ... USE A "AMP" !! THEN (NO LIMITS)
... BUT YES IS NO "TOY" ... MUST BE A #REASON .. TO POWER "UP" ...
... IS NO "JUST FOR FUN" ....
I would not expect, or want, the device to block incoming signals. I would want it to block transmissions from my vehicle.
Some of the devices store locations in memory to be read later. That can't be jammed. Other devices use the cell phone network. Jamming the cell phone network is a very bad idea. There is a very wide frequency spectrum in use by cell phones and it would take a lot more power. The result would be fouling up cell phones over a few miles, including yours.
@@mra-raycom6982Shows you how much I know. I was thinking about just blocking the signal in maybe a 10 foot radius. i see your point about the memory.
cool content
So those external car gps tracker work with 2G 3G 4G network to send data to owner so if i jamme mobile network technology the gps no longer Abel to send location to the owner
First, as I mentioned in the video, jamming is illegal. If you jam the cell phone network, you will be interrupting the connections of yourself, and everyone around you. Now suppose one of those calls is an emergency.
Next, you don't know what frequency the device is on. 2G, 3G, 4G, or 5G are not frequencies, they only designate a protocol. The actual frequency will vary depending on the model of the phone or device and the frequencies that are licensed by the FCC to the service provider in that area. They could be operating in several bands from 600MHz up to 21 GHz. Most phones are multi band so if the connection is interrupted on one frequency, it will jump to another.
On top of that, there are multiple ways to handle the data. Some trackers will store the data in memory for later recovery. Some may use the cell phone system. WiFi is possible. There are also Bluetooth devices that will use passing phones running an app to send data. A couple weeks ago I ran across a gas pump that was transmitting something in VHF spectrum. Pretty much anywhere in the spectrum could be used to send the data and if you attempt to jam all of it in a 100 mile radios, your going to be noticed and your jamming signal will be tracked.
It is harder to jam a transmitter since it is the receiver that would need to be captured. The principal behind the GPS jammer is that the receiver is in your proximity. For data transmissions, the receiver would be at a cell site, mountain top, wifi access point, or someone's mobile phone. It would take much more power.
@@mra-raycom6982 It's illegal in America but maybe he doesn't live in America.
@@parkerbohnn Possibly, but do you know of a country where it is legal to jam? Any of them I have looked up are pretty consistent on that point. The closest I have seen is people claiming there is no enforcement.
@@mra-raycom6982 No one will know if you're blocking the 1.6 gigahertz band. They only care about radar detectors.
@@parkerbohnn Actually radar detectors are of little use because of the burst mode that the radar units use. By the time you get the detect, it is too late.
As for jamming "No one will know" is not true. There may be many circumstances where it is not noticed as with this non-functional jamming unit. However if you cause a problem, there are people who can and will track it down. I know of a group working on such a project for the last few weeks.
Almost like dude is whispering
Cool voice though
shhhh..you're yelling
sounds like batman lmao 😅😅
can this device stop spy drones from looking in my bathroom window ?
No, and as has been said jamming is illegal. Drones operate in a different part of the spectrum.
*NO ...NO MUST BUY THIS "JAMMER" WITH (8 SMALL ANT) ...*
*THINK IT IS 200-300 U.S.D *
*THEY CAN DO .. FROM YOUR PHONE TO YOUR CAR /SAT TV /GPS ... AND*
*YOU WILL FIND .. (DRONES)*
*THEY SEND 1 WATT / 5 WATT ...OUT ... MORE IS BETTER*
*(OR ASK SOME SELLER ...!! YOU NEED DRONE JAMMER)*
*GOOD LUCK*
To evaluate would require testing. It is still going to be illegal, and potentially destructive if critical communication is jammed. @@netautorisationnetautorisa545
They definitely work,you need a blocker for the Flock Surveillance System
That is actually a pretty odd assertion. I tested it on the bench, and in the vehicle. I measured the signal levels and the bandwidth. The reason it didn't work is two fold, and pretty evident. First is that it doesn't cover all the GPS bands so the device simply picks up from the other two bands. Second is that the signal is very weak. at 3 feet it measured -95dBm. Since the expected from the GPS system is -125dBm, it may have worked if the GPS were in the car and it had covered all the bands, but the additional signal loss from the distance outside the car and the loss through the car body would make it ineffective against an externally mounted tracker, or one with an external antenna.
The video demonstrates pretty definitively that it does not work, but if you would like to send in one that you think will, I would be happy to test it on another video.
Ok, sir, what I was wanting to know is dose that device jam aftermarket gps tracking devices that stalkers attach to your vehicle? Also, can not hear what you are saying. I turned on the captions but that thing is inaccurate.
It would depend on the device, frequency and the distance. For the most part, they are both illegal, and a waste of money. You also have to consider that devices such as air tags are not GPS, and would be completely unaffected. The location of air tags is reported by passing phones, not a GPS in the device.
@@mra-raycom6982 oh, wow.
There's a video of a guy using an old cordless phone to supposedly block gps ? I'm being stalked, they're ruining my life. It's been going on for years and they're wearing me down.
Just bought two of them don’t work don’t waste your money. I’m in the car right now. Got them plugged in. My phone is working properly. Didn’t even lose a bar.
They are only intended to jam gps signals to prevent surveillance, rather than jamming cellular or WiFi signals.
Lol
My volume don’t go up enough for this dude
it is illegal to buy these...you will get a big fine if its stopped at customs or company is taken down.
It goes thru Canadian custom, bought several, and it doesn't completely jam the gps signal, you only lose it..
@mr_credentials I meant US. It's illegal to purchase in US.
What??
It is NOT illegal to buy these in the u.s.a.
They are illegal to use, so why would you buy one? There are a lot of games played by importers also and it would take a while digging through bulletins and certifications to determine its actual status.
