Embodiment

[0109] Taking wireless positioning of STAs in a certain building as an example, it includes the following implementation steps:

[0110] 1. Establish the coordinate system of the wireless area on the plane of a certain floor of the building to determine the positions of all APs; create thumbnails in the network management system to identify the positions of all APs on the floor according to the proportion.

[0111] 2. Accurately calculate the λ value in the attenuation model to obtain an accurate attenuation model. The calculation process is as follows Figure 4 Shown:

[0112] The basic model of the wireless signal attenuation model is:

[0113] RSSI d a = RSSI d b - 10 λ lg ( d a d b ...

Abstract

The invention relates to a wireless network management positioning technology and discloses a wireless network positioning method based on an RSSI (Received Signal Strength Indicator), so that an error based on an RSSI wireless network positioning algorithm in a wireless network management system is reduced and a precise position of an STA (Station) is obtained. The method comprises the following steps of a establishing a coordinate system at a wireless network area of one plane and determining positions of all APs (Wireless Access Point); b computing a signal attenuation index lambda value in a wireless signal attenuation model to obtain an optimized wireless signal attenuation model; and c screening an optimal RSSI value of the target STA at the different APs and combining the optimized wireless signal attenuation model to solve the position of the target STA. the method is suitable for wireless network positioning.

Description

technical field [0001] The invention relates to wireless network management positioning technology, in particular to an RSSI-based wireless network positioning method. Background technique [0002] The wireless network management system, as a necessary supporting product of the wireless solution for welcoming guests, the WLAN solution for medical care and education, is of great value both in terms of bidding and actual use by customers. From the perspective of wireless network management applications, the functions that users are most concerned about and that are most urgent in the market include wireless monitoring, wireless resource management, and wireless security. Accurate wireless positioning will make each function more scalable and have business opportunities. [0003] Current wireless positioning mainly relies on wireless sensor networks. Wireless sensor network (WirelessSensorNetwork, WSN) is composed of a large number of micro sensor nodes deployed in the monito...
