Problems solved by technology

[0003] Usually, in the daily use of WIFI routers, along with its large-scale and high-density deployment, there are more and more serious interference problems. The same-channel or adjacent-channel signals of other routers around will cause a certain degree of interference to it. Its performance is reduced to a certain extent, but the existing test methods cannot make a quantitative assessment of this impact
Existing methods can only qualitatively evaluate whether the WIFI router is interfered by other signals in daily use (that is, under typical working conditions), but cannot evaluate the anti-interference ability of the WIFI router

Embodiment Construction

[0025] The idea, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings, so as to fully understand the purpose, features and effects of the present invention.

[0026] Such as figure 1 As shown, one aspect of the present invention provides a WIFI signal testing system, comprising: a router to be tested, an interference source and at least three PCs; the interference source is wired with the first PC, and the first PC transmits the signal by controlling the interference source A wireless user data packet with a fixed power is used as an interference source; the router to be tested is connected to the second PC by wire, and the router to be tested is connected to the third PC wirelessly, and a flow test tool is installed on the second PC and the third PC. The router to be tested, the interference source and the three PCs are all placed in a shielded room.

[0027] With such settings, the te...

Abstract

The invention provides a WIFI (Wireless Fidelity) signal test system and test method. The test system comprises a router to be tested, an interference source and at least three PCs (Personal Computers), wherein the interference source is in wired connection with a first PC; the first PC is used for controlling the interference source to emit a wireless user data packet having constant power to serve as an interference source; the router to be tested is in wired connection with a second PC; the router to be tested is in wireless connection with a third PC; flow test tools are arranged on the second PC and the third PC. By adopting the WIFI signal test system and test method provided by the invention, the system construction is simple and the method is simple, the influences of the same channel and an adjacent channel on the performance of a WIFI router in a working state can be tested quantitatively, and the interference resistance of a wireless router to be tested can be verified rapidly.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a WIFI signal testing system and testing method. Background technique [0002] Wireless access technology WIFI, because of its open communication frequency band, cheap equipment, and easy deployment, is widely used in various local area networks, such as homes, cafes, public places, airports, and large institutions. [0003] Usually, in the daily use of WIFI routers, along with its large-scale and high-density deployment, there are more and more serious interference problems. The same-channel or adjacent-channel signals of other routers around will cause a certain degree of interference to it. Its performance is reduced to a certain extent, but the existing test methods cannot make a quantitative evaluation and judgment on this impact. Existing methods can only qualitatively evaluate whether the WIFI router is interfered by other signals in daily use (...
