Sometimes I don’t think using GPS navigation is a good thing

Today, wireless technology is a very important part of our lives. Mobile phones, radio, WiFi, browser, etc. used in wireless technology. One of the most prominent examples of this widely used wireless technology is GPS.

Now that GPS has been widely used, we have gone to a strange place, first using GPS navigation, so you can easily find the destination, travel route planning will also use GPS navigation. There is no doubt that GPS navigation and our lives are inseparable as this may be the main reason why GPS jammer is considered illegal. They are dangerous because they can destroy important communications.

However, if one day GPS cannot be used, or if GPS can be misused, such as illegal tracking. It is well known that putting all the eggs in the basket is very dangerous, so the GPS navigation system has a few alternatives. They are GLONASS, unit tower triangulation and Wi-Fi navigation. GLONASS is very clear to the public that like Russian type GPS, unit tower triangulation and Wi-Fi navigation need to be explained.

We started from Wi-Fi browsing. The system is under development, but the first step is being carried out by Google. Google has collected information on thousands of Wi-Fi hotspots in the Street View project that can be used for navigation. As long as the physical location of these wireless access points is fixed, the location between at least three locations can be calculated. Use the signal strength to calculate the distance to each hot spot, the closer the hot spot, the stronger the signal. The future can be widely used. But there are two drawbacks: compared to GPS the results are not accurate, only in a large number of Wi-Fi hotspots in densely populated areas. Hopefully with the number of growth of the Wi-Fi network, the accuracy of this technology will increase.

The second technology is the triangulation of the mobile phone's base station, because it uses your own phone to track your location, so it's more convenient. You may know that your phone is connected to at least 2-3 base stations. Their coordinates are known and fixed. Your position is calculated between three unit turns. The advantage of this technique is that it can be used universally because almost everyone has a cell phone which can be signaled by the phone even inside.

Here you can see some tracking techniques without GPS signals, but it also means that there are many ways to track people. In this case, it is recommended to use common multi-frequency rf jammer when you don't know how others are following you.
