RSSI-BASED INDOOR POSITIONING IN THE PRESENCE OF DYNAMIC TRANSMISSION POWER CONTROL ACCESS POINTS

摘要

position fixes for the mobile platform to access points (APs; access points) from It determined using the RSSI value for the received wireless signal and at least one of the access point has a dynamic transmission power control. Transmission power data for the AP is the AP in a separate entity from, for example, is received from the central entity or positioning the secondary server. RSSI value of the radio signal received from the AP are, is obtained as the RSSI heat map. By using the data transmit power, RSSI values and the RSSI heat maps, the position fix for the mobile platform is determined. Position fixes may be determined by a mobile platform, the secondary server or position. Additionally, the server may be provided on a mobile platform the RSSI heat map information on the basis of the transmission power of data and also receives the transmission power data for the AP. RSSI heat map information may include, for example, the transmission power data, or may be RSSI heat maepil incorporating the transmission power data. ;
