Covert GPS Tracking Devices - Keeping Your Privacy
From EjWiki
A simpler solution, and one that should be used when the device is difficult to get to, or you can wrap the antennae in a metal foil, is to use a portable GPS jamming device. These devices work within a small area, but big enough to work on the vehicle you are driving. You can easily find GPS tracking jammers online.
The word Laser actually stands for "Light Amplification by Stimulated Emission of Radiation." It is a form of electromagnetic radiation the same as radio and microwaves. The difference is that light has a much higher frequency than radio or microwaves.
As a professional truck driver, limousine driver or delivery driver - your earnings are diminished by traffic fines. Even the typical driver can't ignore the possibility of getting a ticket and then having to fight the traffic ticket, or pay the fines and risk your insurance rates going up.
There are a number of different kinds of tracking devices that can be installed in a vehicle or piece of equipment. Some of these devices have external wires (antennae) and some don't. The kind of device that is installed, will determine the kind of solution you would be able to use. Some GPS devices have the antennae sticking outside of the housing unit. As technology improves however, more and more devices will have the antennae inside the housing unit. It is also important to see if the device is easy to get to or not. If the device is not easy to get to, then there will be difficult to implement certain solutions to mask the incoming GPS signal (if you can't remove it). Once you have located the tracking device with a sweeper, and have determined the kind of device it is, you can implement the solution.
This is why laser jammers using industry standard laser LED diodes are effective against laser guns. The products calculate distance by measuring the time of flight of very short pulses of infrared light. This method is different from the traditional surveying instrument method of measuring phase shifts by comparing the incoming wavelength with the phase of the reflected light. Any solid object will reflect back a certain percentage of the emitted light energy - it need only be small for the sensitive detector to pick it up. The guns measure the time it takes a laser pulse to travel to the target and back with a precision, crystal-controlled time base. Knowing the speed of light, you then calculate the distance travelled. To increase accuracy, the laser measures as many as sixty pulses, utilizing a least squares method of determining the range. Sophisticated error trapping algorithms are in place to ensure a reliable reading.
A signal jammer is a gadget used to interrupt or dislocate radio signals. It is commonly used to disrupt cellular phones from receiving and transmitting signals. They are usually wireless and can be used in any location to disable cellular phones. It can also be used to interfere with wireless local area networks or WLAN which correspondingly lead to the development and manufacture of jammers like: Bluetooth jammer, Wi-Fi and Wireless video jammers among many others. Hi-tech and sophisticated signal jammers can even jam satellites.
It is important to use jammers nowadays - no matter cell phone or GPS jammers, they are important if you want to keep your private life. In the modern world there are so many electronic technologies, military develops and systems that it is completely possible that everyone is being constantly tracked.
It is known that the phone signal is influenced by your indoor position, weather condition or even time. According to the experience of the scientists if you change the value to 10dbm you will be able to reach the highest power. In that way the distance is doubled and you will be able to catch the signal from places that you were not before. Scientists do not recommend to this often because it can be dangerous for the technology. Anyway, there are some occasions that may allow you to do it - for example some important military operation. By doing this procedure you will be able to catch a signal from distances far away.
Anyway the cell phone jammer can not work constantly without stopping. And it can block approximately 98 percent of the area. It lifetime is around 8 hours. The bad news here is that no matter what are the environment changes the cell phone jammer can not always block all cell phones around - just most of them but there will always be 2 percent that will work.
Another more commonly used is the GPS signal jammer. These are commonly used by the military to confuse GPS tracking for locations. Similarly, there are no homemade tracking systems like this. Civilians who make use of these jammers to hide or cover up his location and that of his vehicle should in case it is being tracked by a GPS receiver. A civilian GPS jammer usually covers up to 10 meters only.
Signal jammer will have some difficulties in interfering with other electronic devices which are in good working condition. These jammers are also used and regulated by the government and are usually intended to jam cellular phone communication lines only. Similarly, They only damaged the receiving end of a cellphone call because it directly interferes with the cell phone and the base station itself. It has a relatively small electromagnetic wave and as such, it has no known damage to the human body as well as to the cellular phone itself. However, if the jammers are bigger, like outdoor signal stations there can be health repercussions for such.
