ACCESS POINT WHICH TRANSMITS GEOGRAPHICAL POSITIONING INFORMATION FROM THE ACCESS POINT TO MOBILE TERMINALS, AND MOBILE TERMINAL WHICH RECEIVES THE INFORMATION AND DETERMINES THE POSITION THEREOF BASED ON SAID INFORMATION

摘要

The invention relates to an access point (20) which sends geographical positioning information from the access point to mobile terminals (10) and to a mobile terminal which receives this information and estimates the position thereof based on said information. Geographical-locating architecture for WiFi 802.11 mobile terminals on ADSL access points generally consists of including geographical positioning information, i.e., the geographical coordinates of the access point during the registration phase thereof. The access point includes this geographical information in the information posted so that the mobile terminals can be connected to same. The mobile terminals can thus know the geographical location where they are located with an approximation that will depend directly on the number of access points that the mobile terminal can detect.
