UWB and WiFi positioning comparison

UWB ultra-wideband positioning and
positioning principle: In the indoor positioning system, the positioning tag worn on the person or article uses the UWB pulse signal to transmit position data, which is received by the positioning base station, and the time difference for the positioning tag signal to reach different positioning base stations is calculated, and then the software is processed The position is settled, and the position of the positioned object is finally obtained. WIFI
positioning technology
Positioning principle: With the help of WiFi network, the device only needs to turn on WiFi, whether connected or not, it can scan and collect the surrounding wireless AP signals. The device sends the data signal to the location server. The server combines the strength of each signal to calculate the geographic location of the device and returns it to the user device.
In contrast, it can be seen from the positioning principle that the difference between the two is quite big. One is to use the WIFI network, the other is mainly to use the positioning tag, and the method of calculating the distance between the two is different. One is based on the strong signal. One is the use of certain algorithms.
In addition, UWB (Ultra Wideband Technology) is a new type of indoor positioning technology. Compared with WIFI, it has high transmission rate, low transmission power, strong penetration ability, no carrier, good anti-interference effect, high security, and complex system. The advantages of low degree of accuracy and high positioning accuracy. At present, there are many companies engaged in UWB technology. Yunku Technology is one. The UWB personnel positioning system developed by it has been widely recognized by the industry by virtue of its own advantages.
