Interfering devices are radio frequency transmitters that intentionally block, block or interfere with legitimate communications, such as cell phone calls, text messages, GPS systems, and Wi-Fi networks. Previously, this equipment was made for military purposes. Although gps jammer have been manufactured (especially governments, military organizations and spies or small private companies), most civilians do not have the technical capabilities to create their own homemade devices. This is much more difficult than blocking radio signals with basic radio interference. It is best to equip GPS jammers within a certain period of time. Especially the friends of car dealers who collect the car and buy the mortgage car, that is to say, once you receive the car, you can open the GPS jammer and put one in the car, and one in the trunk! With the shield on, you can ensure that you have no worries during the return journey. However, the GPS signal jammer cannot be turned on 24 hours a day, so after safely arriving at your site, you must find a professional person to investigate the GPS by yourself, and install a GPS positioning device, a concealed lock, and a key change to prevent mistakes in security.
How to make the GPS positioning of the vehicle invalid? It is necessary to know that the locator is just like a mobile phone, it needs to install a SIM card to receive and send information, so it has a certain frequency in the working state. At this time, if you want the locator to fail, you need to use a GPS jammer. When it starts to work, it will intercept the signal sent by the locator on the car. In this way, the real-time tracking function of the locator will be invalid, which can be said to be a simple and rude method. Although the GPS jammer can effectively interfere with the signal of the locator, this approach is to treat the symptoms and not the root cause. After all, GPS is still in it. At the same time, the mobile phone signal will still be interfered. If there is any important call or information, it will be delayed by the GPS jammer. In general, GPS jammers are not very useful, so it is better to eliminate GPS completely.
