Abstract: A dynamic channel allocation system and a network device are disclosed. The method includes: After obtaining signal interference distribution between a plurality of APs and an occlusion relationship between the plurality of APs, a radio controller allocates channels to the plurality of APs based on the signal interference distribution and the occlusion relationship, where channels allocated to APs that have an occlusion relationship are different. In this application, after obtaining the occlusion relationship between the plurality of APs, the radio controller allocates, during channel allocation to the plurality of APs, different channels to APs that have an occlusion relationship, so that co-channel interference caused by the case in which a same channel is allocated to an occluded AP pair is avoided, and communication quality of a wireless network is improved.
