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.

Abstract: An obstacle recognition method and apparatus, and a related device are provided. The method includes: obtaining an actual path loss value between a first AP and a second AP, path loss value pairs between a terminal and a plurality of AP pairs, and path loss values of the plurality of AP pairs; obtaining, based on the path loss value pairs between the terminal and the plurality of AP pairs, an AP pair similar to an AP pair formed by the first AP and the second AP; obtaining a second path loss value between the first AP and the second AP based on a path loss value of the similar AP pair; and comparing the second path loss value between the first AP and the second AP with the actual path loss value, to determine whether an obstacle exists between the first AP and the second AP.
