Method and system for testing emission parameters of wireless local area network

Abstract

The invention relates to a method for testing emission parameters of a wireless local area network. According to the method, the emission parameters are tested after emission parameter signals of the wireless local area network are converted into low-frequency digital signals. Correspondingly, the system for testing the emission parameters of the wireless local area network comprises an emission parameter testing module and a PXI (peripheral component interconnect extensions for instrumentation) hardware modular instrument, and the PXI hardware modular instrument comprises a PXI vector signal analyzer including a digitizer, a down converter and a continuous waveform generator. By means of mutual connection of the digitizer, the down converter and the continuous waveform generator, the emission parameter signals of the wireless local area network are converted into the low-frequency digital signals, and the low-frequency digital signals are transmitted to the emission parameter testing module for testing. The system can greatly enhance sharing and interaction of tested information so as to play a good guide role in development of testing systems and has high performance and precision, and testing efficiency is improved.

Description

technical field [0001] The invention relates to a test method and a test system for wireless local area network transmission parameters. Background technique [0002] In recent years, the automotive network has attracted more and more attention. The wireless communication standard DSRC is used to realize short-distance communication services for roadside-to-car and car-to-car public safety and private event communications. From a technical point of view, compared with general wireless communication methods, 802.11p has made many improvements for special environments such as cars, such as: more advanced switching between hotspots, more support for mobile environments, enhanced security, and enhanced identity Certification etc. [0003] Wireless LANs based on the IEEE 802.11 standard allow wireless connections using unlicensed 2.4 or 5.8GHz radio frequency bands in a LAN environment. They are used in everything from homes to businesses to Internet access hotspots. [0004] ...

Problems solved by technology

In the traditional test method, the software used to test the signal is fixed in the hardware that converts the signal. Such a software device has a single test function, which is difficult to upgrade and makes the test system lack of scalability.

[0010] Not only that, the test for IEEE 802.11p transmission parameters has not been clearly defined, and it is blank. Therefore, most technicians have no way to start with the test of IEEE 802.11p transmission parameters, which makes it impossible to accurately know the characteristics of IEEE802.11p transmission parameters. The Application and Development of IEEE 802.11p Network Protocol Brings Inconvenience
