A Study of WLAN RSSI Based Distance Measurement Using EEMD [PDF]

, 2013
Received Signal Strength Indicator (RSSI) was deemed that it is not applicable for WLAN localization directly, as it is highly influenced by environment and limited by the measurement device. This distortion must be avoided to improve RSSI based distance
