How does BLE work?

BLE positioning with sensors utilizes BLE-enabled sensors that are deployed in fixed positions throughout an indoor space. These sensors passively detect and locate transmissions from BLE smartphones, asset tracking tags, beacons, personnel badges, wearables and other Bluetooth devices based on the received signal strength of the transmitting device. This location data is then sent to the central indoor positioning system (IPS) or real-time location system (RTLS). The location engine analyzes the data and uses multilateration algorithms to determine the location of the transmitting device. Those coordinates can be used to visualize the location of a device or asset on an indoor map of your space or leveraged for other uses depending on the specific location-aware application.
