A Comprehensive Study of Bluetooth Signal Parameters for Localization

The authors provide an elaborate discussion on Bluetooth signal parameters with respect to localization, whereby they collectively designate all types of Bluetooth specification parameters that are related to signal strength - such as RSSI, Link Quality, Received and Transmit Power Level - as Bluetooth signal parameters. According to their analysis and experimental results, "RSSI" and "Transmit Power Level" turn out to be poor candidates for localization, while "Link Quality" has its limitations. On the other hand, "Received Power Level" correlates nicely with distance, which makes it the most desirable Bluetooth signal parameter to be used in location systems.
