Preface Bluetooth is a short-distance wireless communication technology, which can be transmitted through a short-distance communication network. Bluetooth is also used to locate mobile phones and personal digital assistant (PDA) devices. Bluetooth can be used to develop various applications such as security positioning and smart home positioning. Bluetooth positioning technology 1. Automatic positioning: By installing

RTLS is abbreviation for Real Time Location Systems. RTLS is a signal-based radiolocation method that can be active or passive. Among them, the active is divided into AOA (arrival Angle positioning) and TDOA (arrival time difference positioning), TOA(arrival time), TW-TOF(two-way flight time), NFER(near-field electromagnetic ranging) and so on. Talking about positioning, everyone will first think

At present, the Charging station market in the Chinese market is still in the development stage. Benefiting from the increased acceptance of the pure electricity market, increased policy driven subsidies, and increased willingness of vehicle enterprise operators to invest, the demand and supply of Charging station in China's main markets are expected to increase significantly.

High-precision Bluetooth positioning generally refers to sub-meter or even centimeter-level positioning accuracy. This level of accuracy is significantly different from the 5-10 meter accuracy provided by standard positioning technologies. For example, when searching for a specific store in a shopping center, a positioning accuracy of 20 centimeters or less can greatly assist in finding the
