Today’s wireless technology is a very important part of our lives and has become inseparable. Mobile phones, radios, WiFi, browsers, etc. are used in wireless technology. GPS is one of the most compelling examples of this widely used wireless technology. We can be tracked without knowing it, or we can disclose our personal privacy.
Now that GPS has been widely used, we have gone to an unfamiliar place, first use GPS navigation, so that you can easily find your destination, and will also use GPS navigation when planning travel routes. There is no doubt that GPS navigation is inseparable from our lives, because this may be the main reason why gps jammer are considered illegal. They are dangerous because they can disrupt important communications.
However, if one day GPS cannot be used, or GPS may be abused, such as illegal tracking. As we all know, putting all eggs in a basket is very dangerous, so there are some alternative methods for GPS navigation systems. They are GLONASS, cell tower triangulation and Wi-Fi navigation. GLONASS is very clear to the public. Like Russian GPS, it must explain cell tower triangulation and Wi-Fi navigation.
We started with Wi-Fi browsing, the system is under development, but the first step is done by Google. Google has collected navigational information from thousands of Wi-Fi hotspots in the “Street View” project. 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. It can be widely used in the future. But there are two disadvantages: Compared with GPS, the results are not accurate, and only exist in a large number of Wi-Fi hotspots in densely populated areas. Hope that as the number of Wi-Fi networks grows,
The second technique is triangulation of mobile phone base stations, because it uses your own phone to track your location, so it is 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 technology is that it can be used universally, because almost everyone has a mobile phone that can send signals through the mobile phone even indoors.
Here, you can see some tracking technologies without GPS signals, but it also means that there are many ways to track people. In this case, it is recommended that you use a general-purpose multi-frequency RF jammer when you do not know how others follow you.
