Automatic radio frequency test method for WiFi (Wireless Fidelity) product

Abstract

The invention provides an automatic radio frequency test method for a WiFi product. The automatic radio frequency test method comprises the following steps: creating a test hierarchical structure through a processing module; enabling the created test hierarchical structure to comprise a product abstraction layer and a device abstraction layer; aiming to different types of WiFi products and radio frequency test devices, designing the abstraction layer with the unified interface according to the common attributes of the different types of WiFi products and radio frequency test devices; selecting the appropriate radio frequency test method to test the WiFi product. The automatic radio frequency test method disclosed by the invention can support a plurality of types of WiFi products and radio frequency test devices, and is friendly in user interface, powerful in functions, high in test efficiency, unified in programmatic interface, furthermore complete in functions, and capable of operating multiple modes; the automatic radio frequency test method is implemented by an advanced programming language, so as to greatly lower the difficulty of development and maintenance as well as the workload, tremendously simplify development and maintenance of the radio frequency test program, and reduce the test cost.

Description

technical field [0001] The invention relates to the field of radio frequency testing of WiFi products, in particular to an automatic radio frequency testing method of WiFi products. Background technique [0002] With the rapid development of wireless local area networks, WiFi products such as wireless routers and wireless network cards have been widely used in various fields. As a wireless communication product, WiFi products must conform to the radio frequency specification defined by IEEE802.11, and a radio frequency (Radio Frequency, RF for short) test is mandatory before leaving the factory. [0003] There are two types of RF test equipment, one is the traditional spectrum analyzer (Spectrum Analyzer, referred to as SA) and power meter (Power Meter, referred to as PM), this type of equipment uses general input and output instructions to interact, and the programming is simple but the function is single. Another type of equipment is a comprehensive tester, including IQVi...

Problems solved by technology

[0005] In the prior art, due to the huge difference between WiFi chip solutions and RF test equipment, the past automated RF test programs were developed separately for different WiFi chip solutions and equipment; not only the programs of different WiFi chip solutions are different, but also a The WiFi chip scheme has different procedures on different test devices

Therefore, it is necessary to develop and maintain a large number of test programs, which increases the difficulty and cost of development and maintenance; when a certain program problem needs to be modified, all test programs need to be modified, so the inevitable repetitive actions are extremely time-consuming and manpower-intensive. big waste
