System and method for testing wireless roaming function of USB wireless network card equipment

Abstract

The invention provides a system for testing wireless roaming function of USB wireless network card equipment. The system comprises a wireless network controller, a wireless access point, a programmable attenuator, a PC client and a wireless network card to be tested. wherein the wireless access point and the wireless network card to be tested are respectively arranged in independent shielding boxes, the wireless access point is connected with the wireless network controller through a network cable, and the shielding box where the wireless access point is located is connected with the programmable attenuator through a radio frequency line. The invention also provides a method for testing the wireless roaming function of the USB wireless network card equipment. The beneficial effects of theinvention are as follows: the problems of long testing time and data deviation during repeated testing due to interference of the surrounding environment when the roaming function is tested in an openenvironment are solved, s a stable testing environment and method are provided, the testing efficiency is improved, repeated utilization rate of the testing environment is high, the testing cost is reduced, and obtaining of a relatively accurate testing result is facilitated.

Description

technical field [0001] The invention relates to a wireless network card test, in particular to a wireless roaming function test system and method of a USB wireless network card device. Background technique [0002] The wireless roaming function means that after multiple wireless access points in the same LAN have enabled the wireless roaming function, they have the same wireless signal name, encryption method and wireless key, and their coverage areas overlap to a certain extent. When the wireless client moves from the coverage area of ​​one wireless access point to the coverage area of ​​another wireless access point, it can automatically select the wireless signal with better signal to connect, and ensure uninterrupted network connection. [0003] In the prior art, the wireless roaming function test of the USB wireless network card is to deploy a wireless access point with the wireless roaming function enabled in different locations where the three wireless coverage areas ...

AI Technical Summary

Problems solved by technology

[0005] (1) The test environment is an open environment, and the surrounding wireless transmission paths and wireless interference are prone to change. There is a possibility of service freeze caused by surrounding wireless interference. There are many variables in the test environment, and it is impossible to judge the test results of the wireless roaming function alone. And it is difficult to compare the test data of different time periods;

[0006] (2) It is difficult to obtain accurate values ​​to support the development of functions through the viewing experience of video or voice during testing;

[0007] (3) It is necessary to rent a large-area flat, duplex building or villa with high cost during the test, and each test requires manpower to build a test environment, and the cost is high.
