Problems solved by technology

[0002] With the popularization of WLAN (Wireless Local Area Network, WLAN), the evaluation of WLAN electromagnetic radiation intensity is becoming more and more important. At present, most of the research on WLAN electromagnetic radiation usually only regards WLAN as a single site, and does not consider the joint interference power Taking it into consideration, when WLAN transmits data, the greater the distribution density of users and access points, the stronger the interference, and the greater the WLAN duty cycle and electromagnetic radiation. However, in the relevant literature and patents that have been published so far, There is not yet a way to combine WLAN electromagnetic radiation with joint interference power theory

Abstract

The invention discloses a WLAN electromagnetic radiation prediction method based on joint interference power. The steps are as follows: According to the area distribution of WLAN, the distribution of the number of users within the WLAN range is obtained, and then the joint interference power is calculated, and the joint interference power is calculated according to the obtained joint interference power. SINR value, and further calculate the WLAN duty cycle, and finally use the spectrum analyzer to measure the maximum electromagnetic radiation intensity of the WLAN, combined with the obtained duty cycle, predict the average electromagnetic radiation intensity of the WLAN. According to the combined interference power, the invention analyzes and obtains the duty cycle of the WLAN, and accurately predicts the average electromagnetic radiation intensity of the WLAN.
