The database of relationship between intensity and sampling point position, that is, the database or radio map of location fingerprint；In order to generate this
Database needs the region division grid positioned in needs, sampled point is established, using wLAN receiving device in all sampled points
It samples one by one, records the position of each sampled point, RSSI and AP address information obtained, deposited after handling sampled data
Storage is in the database；In real-time positioning stage, user's handheld terminal moves in the region that positioning device covers, WLAN
The information for the current address RSSI and AP being collected into is uploaded in database and is carried out by the current address RSSI and AP of network real-time reception
Matching obtains estimated position, and the signal strength or weakness that Wireless LAN is received is with numerous data progress in database
Match, real-time positioning is realized with this.
