5 Overview
As shown in Figure 1, the WLAN system is based on the existing general cabling system. The WLAN system involved in this standard is the part in the solid frame in Figure 1. This system consists of three equipment types, i.e., STA, AP and ASU. The functional requirements of such equipment are given in GB 15629.11 series. This standard mainly aims at proposing the testing methods for STA, AP and ASU specific to the functional requirements given in the above standards. In addition, it specifies the engineering testing method of WLAN system by combining with the specific system requirements.
