Possible LoJack / Boomerang security breach....
 

For those of you with the LoJack or Boomerang security systems...

This might be a bit of an issue.

I know if I was a car thief I'd have one of these for sure....

Can someone please explain to me how this device contributes to society?? Please, anyone have a legit reason to own such a thing??

Question is if it's strong enough to actually jam signals.

1. If you don't want your parents or your spouse to know your whereabouts.

2. If you are a car thief.

3. If you are an ex-employee of LoJack and you want revenge.

:)

Don't see why not. It should be easy to overpower weak satelite signals...

LMFAO at # 1 and 2

Or maybe you're just tired of "Big Brother" peeking more and more into your life. Where you drive, how fast you drive, etc. Bad enough most every car has a chip now that records everything you do with the vehicle but then rental cars outfit GPS devices on their cars. There is a movement underway to have all cars (in the US) fitted with GPS so you can either be charged for the number of miles you drive or pay a surcharge on the number of miles you drive.

(think about the poor schmuck who bought a hybrid car to save money on gas only to be charged for the miles it's driven instead)

Dont believe LoJack uses GPS at all - its like a homing beacon that, when the cops tune their receiver to the frequency, it points them in the direction of the car, along with receiving a relative potential distance.

Two things:

1) LoJack does not work with GPS signals.

2) This device is a worthless POS just like the so-called "radar jammers".

While GPS jammers have been created (specifically by the government, military organizations and spy or privacy gadget companies), most civilians do not have the technical capabilities to create their own home made device. It is much more difficult than just blocking a radio signal with basic radio interference.
Most GPS Jammers are built for military uses, for instance, to confuse the enemy on where their exact location is or where the enemies GPS guided missiles or bombs will fall. However, there are a few civilian uses for jamming GPS signals including the ability to conceal oneself or one's vehicle in the case that it is being tracked by a GPS receiver.
It should be noted that most GPS jammers are illegal to build or use in many countries or localities due to the potential for misuse. For instance, a GPS jammer can confuse aircraft and other vehicle instruments, possibly causing mishaps. Some GPS jammers state that they are only for civilian GPS jamming only; however some military equipment, must first sign onto the civilian GPS radio <nobr style="font-weight: normal; font-size: 100%; color: darkgreen;" id="itxt_nobr_5_0">frequencyhttp://images.intellitxt.com/ast/adTypes/2_bing.gif</nobr> in order to gain access to the military GPS frequency.

lojack works like a radio single i think

GPS jammers are for people who don't want to be tracked by someone else. Commercial vehicles are often tracked by GPS so the company knows where their vehicles are at any given time. Not all employees cooperate with the corporate surveilance. Some rental car companies charge big extra fees if the vehicle is taken out of state. I remember being warned about extra charges if the vehicle was taken out of state when I rented a car in Las Vegas.
For a GPS jammer to be legal it would have to operate under the FCC rules for radio transmitters. Even if these jammers are Part 15 devices(less than 100mw) I doubt transmitting on GPS frequencies is legal.

1 - good point. Interesting to note how LoJack actually works and that its a joint venture between LoJack and POSSIBLY your local Police and not all police cars are necessarily equiped with LoJack. I'm sure the system helps but the huge cost for the initial install and the large monthly fees doesn't make it look like a good value for your money unless your insurance company is going to significantly reduce your insurance premiums.

2. Military GPS is encrypted so its unlikely that you're going to fake out an incoming missle. Since most GPS recievers are sensitive to signals at -135dB how hard do you think it would be to flood the front end of the reciever? Even "a worthless POS" could easily do the job. Most civilian GPS runs on L1 which makes it even easier to jam.

Hmmm, here's a thought. So you know someone who uses a GPS often who deserves some negative carma. Wire one of these jammers up under their hood where they can't find it. Could you imagine how much frustration this might cause :tiphat:

Not only is it illegal, it is a Federal offense, I imagine. Never eff with the Feds unless you enjoy living at their expense in a nice clean cell.

One of my cars has LoJack and I don't pay any monthly fees (there's just the up-front purchase and installation fee). And my insurance company does reduce my premiums.
