Indoor positioning system as long as what positioning methods?

The indoor positioning system uses more positioning methods, WIFI positioning, Bluetooth positioning, UWB high-precision indoor positioning

WiFi indoor positioning technology is divided into two kinds, through the mobile device and the three wireless network access points of wireless signal strength, through the differential algorithms, to be more accurate to triangulation of people and vehicles, and to determine the position of the huge amount of records in advance. The signal strength of the points is used to determine the location by comparing the signal strength of the newly added devices with the database that has a huge amount of data. This type of positioning can achieve complex wide-area positioning, but the maximum accuracy can only reach 2 meters.

Bluetooth positioning technology is a cell phone through the Bluetooth function to achieve positioning of a positioning method, this positioning technology in addition to the use of cell phone Bluetooth module, but also need to deploy the Bluetooth base station, the highest can reach sub-meter positioning accuracy. The advantages of Bluetooth indoor positioning technology are small size of the device, short distance, low power consumption, easy to integrate in mobile devices such as cell phones. As long as the Bluetooth function of the device is turned on, it is able to locate it. Bluetooth transmission is not affected by the visual distance, but for complex spatial environments, the stability of the Bluetooth system is slightly worse, by the noise signal interference and lies in the Bluetooth devices and equipment is more expensive.

3. Ultra-wideband indoor positioning personnel management system, which is an emerging wireless technology in recent years, this positioning system, fast transmission speed, low transmit power, penetration is also very strong, anti-jamming is also very strong, and you can get accurate results, the disadvantage is that, now the higher cost, so as long as the solution to the problem of the cost, then the ultra-wideband positioning technology, in the field of wireless indoor positioning will have a very good prospect.

From a technical point of view, whether from the positioning accuracy, security, anti-interference, power consumption and other perspectives to analyze, UWB is undoubtedly one of the most ideal industrial indoor positioning technology.
