Abstract

The invention discloses a mobile device positioning system. The mobile device positioning system comprises access points (APs), a positioning server, a network adapter and a positioning computing engine (PCE). The access points (APs) are wireless local area network (WLAN) access points, and the number of the access points is one or more than one. The positioning server comprises a radio signal strength (RSS) characteristic database, and the RSS characteristic database provides an RSS distribution diagram of the access points (APs) based on a set of disperse locations in a target area. The network adapter is used for providing network connection service of a mobile device and the access points (APs). The positioning computing engine (PCE) is used for determining positions of the mobile device based on the RSS characteristic database and receiving signals from one or more than one access point. According to the mobile device positioning system and method, RSS of neighboring multiple access points (APs) received by the mobile device like WIFI labels and an intelligent cell phone with RSS characteristic data of the disperse locations in the target area in the database are compared, and therefore two-dimensional locations of the plane where the mobile devices are positioned can be determined.

Description

technical field [0001] The present invention relates to a mobile device positioning system and method. Background technique [0002] The widespread use of smart phones and low-power WIFI transceiver tags makes it possible to provide indoor positioning services based on low-cost local area wireless network (WLAN) devices, which will cover a variety of service solutions such as indoor positioning, tracking, navigation, and security. Some mobile devices (such as mobile phones using Android or IOS systems) and WIFI tags can communicate with the central server intermittently through certain settings to obtain current location information, so as to achieve the positioning effect. However, due to the complexity of indoor environments, it is often difficult to provide satisfactory positioning accuracy by methods based on wireless signal propagation models such as time of arrival (TOA), angle of arrival (AOA), and RSS-based triangulation, etc. . Therefore, machine learning-based RS...
