Wireless signal RSSI (Received Signal Strength Indication) is widely used in indoor localization. However, due to severe multipath effect in indoor environment, RSSI measured by the user equipment varies in a large range. Inaccurate RSSI measurement yields large localization error and decreases the performance of indoor localization and navigation. Through extensive tests, we prove that the variance of RSSI in indoor environment does not keep the same all the time, while varies with the mean of… CONTINUE READING
