Indoor wireless distributed system engineering quality self-detection method, equipment and system

The invention provides an indoor wireless distributed system engineering quality self-detection method, equipment and system, and the method comprises the following steps: generating a self-detection signal, and carrying out the blind communication with slave equipment through a time slice polling mode; acquiring a supported capability set reported by the slave device; according to the capability reported by the slave device, performing traversal testing of the coding mode and the rate; and reporting a test result. The expansion unit is used as the master device, the self-inspection signal is directly generated, and the self-inspection of the installation quality is carried out according to the capability of the slave device, so that the problem of independent entrance and independent acceptance of constructors and station opening personnel in the indoor distribution construction stage of the expansion leather base station can be solved. A common constructor can complete equipment installation and cable insta
