Witrynautilize Received Signal Strength Indicators (RSSI) have been proposed to provide PBS and LBS for indoor environments, though each solution presents its own drawbacks. In this work, Bluetooth Low Energy (BLE) beacons are examined in terms of their accuracy in proximity estimation. Specifically, a mobile Witryna28 cze 2024 · RSSI is an indicator for how well receivable a receiver considers a signal – that's typically not inherently dominated by the signal strength, but by factors like noise and interference. Thus, it's a device-specific estimate for how well the bluetooth device is able to receive someone else. Nothing more, nothing less.
