Abstract
Description
technical field
[0001] The present invention relates to the technical field of navigation, in particular to an indoor navigation method, device and mobile terminal. Background technique
[0002] Indoor positioning technology based on Wi-Fi or Bluetooth.
[0003] Wi-Fi positioning technology, based on RSS (Received Signal Strength, received signal strength) positioning of mobile terminals. Before positioning, APs (Wireless Access Points) need to be deployed indoors. The denser the deployment of APs, the better the positioning effect. Each AP has a globally unique MAC (Media Access Control, Media Access Control) address, and generally for an AP, the MAC address will not change within a period of time. The MAC address is mapped to the indoor physical address, thereby establishing a location database for Wi-Fi positioning.
[0004] The mobile terminal scans and collects surrounding AP signals, collects messages broadcast by the AP, and obtains the MAC address of the AP from t...
