Wi-Fi software testing system and method

Abstract

The invention discloses a Wi-Fi software test system. The Wi-Fi software test system comprises a test script subsystem, a plurality of simulation verification subsystems and an air interface simulation subsystem. Each simulation verification subsystem is used for simulating one piece of Wi-Fi equipment, and at least one piece of simulated Wi-Fi equipment is provided with tested Wi-Fi software. Each simulation verification subsystem comprises an operating system adaptation layer, a driving software layer, an MAC software layer and a PHY software layer. The operating system adaptation layer receives a test command and a test parameter sent by the test script subsystem and converts the test command and the test parameter into an instruction for driving the software layer; the driving softwarelayer is used for realizing the control on Wi-Fi chip hardware; the MAC software layer is used for realizing wireless media intervention control and controlling data transmission; and the PHY software layer realizes receiving and transmitting of MAC frames, and comprises a simulated air interface for interacting with the air interface simulation subsystem; the air interface simulation subsystem is used for simulating a wireless channel environment of a wireless local area network. According to the invention, before the Wi-Fi chip is manufactured, the software of the Wi-Fi chip can be tested.

Description

technical field [0001] The present application relates to a system and method for testing software of a Wi-Fi chip. Background technique [0002] Wi-Fi is a radio frequency technology based on the IEEE 802.11 protocol, commonly used in wireless local area network (WLAN) devices. The current test method for Wi-Fi chips is based on a set of test systems. Wi-Fi devices (that is, devices containing Wi-Fi chips) are placed in the test system, and the PHY (physical Layer), MAC (Media Access Control Layer) behavior according to the IEEE 802.11 protocol for functional testing and performance verification. [0003] see figure 1 , which is an existing Wi-Fi device testing system. The Wi-Fi device testing system includes a test script control PC (personal computer), a console PC, a tested Wi-Fi device, an AP (Access Point, access point), and other network devices. The tested Wi-Fi device, AP and other network devices are connected through the wireless local area network, and the ab...

Problems solved by technology

Each test system requires multiple PCs, and the hardware cost is high

Second, it can only be tested after the Wi-Fi chip is produced

When the Wi-Fi chip is not produced before the development process, after the R&D personnel complete the software code of the Wi-Fi chip, they cannot pass the existing test system to test the driver software, PHY layer protocol software, and MAC of the Wi-Fi chip. Layer protocol software is tested, which is a difficult problem faced by the development and debugging of Wi-Fi chip software
