技術原理

BLE 與 UWB 技術對比

定位原理

Triangulation Method

By measuring the distance between the positioning tag and multiple base stations, the system applies the principle of triangulation to calculate the precise location of the tag.

TDOA (Time Difference of Arrival)

By measuring the time difference of arrival (TDOA) of signals at multiple base stations, the system calculates the precise location of the positioning tag. Ultra-Wideband (UWB) technology primarily employs this method, achieving centimeter-level positioning accuracy.

RSSI (Received Signal Strength Indicator)

By calculating the distance based on signal strength attenuation, Bluetooth Low Energy (BLE) technology primarily employs this method. While it is cost-effective, its positioning accuracy is lower compared to Ultra-Wideband (UWB).
