Multi-frequency jammers can make you more secure

Nowadays wireless technology is a very important part of our lives. Mobile phones, radios, WiFi, navigator, etc. are applied to wireless technology. One of the most prominent examples of such widespread wireless technologies is GPS.

Now GPS is widely used, we went to an unknown place, the first use is GPS navigation, so that you can easily find the destination, route planning will also use GPS navigation. There is no doubt that GPS navigation and our lives are inseparable. This could be the main reason why GPS signal blockers are considered illegal. They are dangerous because they can destroy important communications.

However, if one day GPS cannot be used or GPS can be used incorrectly, e.g. B. Illegal tracking. It is known that putting all eggs in one basket is very dangerous. Therefore there are some alternatives to the GPS navigation system. They are GLONASS, Unit Tower Triangulation and Wi-Fi navigation. GLONASS is very clear to the public, it’s like a similar GPS in Russia, and unit tower triangulation and WiFi navigation may need to be explained.

We started with WiFi navigation. The system is under development, but the first step is being taken by Google. Google has gathered information about thousands of WiFi hotspots that can be used for navigation in the Street View project. As long as the physical location of these wireless hotspots is determined, the location can be calculated between at least three locations. Use signal strength to calculate the distance of each hot spot, the closer the hot spot is, the stronger the signal. The future can be widespread. But it also has two shortcomings: its results are not accurate compared to GPS. And it can only be used in densely populated areas where there are a large number of WiFi hotspots. It is hoped that the accuracy of this technology will increase with the number of Wi-Fi networks.

The second technology is the triangulation of the cellular base station, which is more convenient because it uses your own phone to track your location. You may know that your phone is connected to at least 2-3 base stations. Your coordinates are known and fixed. And your location is calculated between the three unit towers. The advantages of this technology are: It can be used universally because almost everyone has a cell phone that can be found via telephone signals, even indoors.

Here you can see some tracking technology without GPS signal, but it also means that there are many ways to track people. In this case, it is advisable to use an ordinary multi-frequency signal jammer if you are not sure how others are tracking you.
