GPS car blockers are important to some customers. For example, a car mortgage company temporarily obtains the right to use the car after releasing the money to the original owner. In order to prevent the vehicle from being secretly stolen by the original owner, such a company will purchase GPS blockers, install it in the parking lot where the vehicle is stored, and install it in the car. It is installed on the top, so that the original owner cannot locate the vehicle, thus protecting the property safety. So how to choose a vehicle GPS signal jammer? Next, let's take a look with jammer mart!
Some customers have some misunderstandings, thinking that the positioning on the car is only achieved through GPS, and buying a car GPS signal jammer can cut off the positioning. In fact, location positioning can be roughly divided into two categories: GPS (Global Positioning System, global positioning system) and LBS (LBS-Location Based Service, mobile location service). As far as the technical principle is concerned, GPS vehicle positioning performs positioning by accepting the latitude and longitude coordinate signals provided by GPS satellites, while LBS calculates the location of the vehicle through the difference of base station signals of mobile communication. Therefore, it is not enough to shield GPS only, and you should choose a device that is fully shielded by mobile phones and GPS.
So there are so many car GPS signal jammers on the market, including hand-held and plug-in (larger in appearance than routers), which one is better? Let’s talk about the handheld gps jammer one first, its advantage is that it has a small appearance , easy to carry, easy to hide, and can be standby after charging; but the disadvantage is that the shielding distance is short, the effect is very unstable during high-speed driving, only suitable for relatively small models, and after the battery is fully charged, it can only be used. Standby for about an hour.
What about the plug-in type? The plug-in car GPS signal jammers are usually metal shells with seven, eight or even nine external antennas. This kind of jammer can be directly inserted into the cigarette light when it is used in the car. On the device, when using it in the garage, just plug in the 220V power directly. Its disadvantage is that the appearance is a little big and difficult to place, but the advantage is that the shielding effect is good and the distance is long. Even in the process of high-speed driving, it can fully meet the needs of shielding, and it can also be used in the garage. One such GPS signal jammer can shield about 200 square meters under normal signal environment, which is a very good choice for mortgage loan companies at present!
