Abstract
There are a variety of services in underground pipe gallery, and these services should be isolated during data transmission to ensure communication security. WiFi6(802.11ax) has the advantages of fast transmission rate, low energy consumption and low cost, and is suitable for carrying the underground pipe gallery communication service. In order to ensure the reliability of underground pipe gallery service transmission, it is necessary to study the communication isolation technology of WiFi6. In this paper, a communication isolation technology based on WiFi6 is proposed, and the communication isolation architecture of underground pipe gallery is designed to realize communication service isolation in frequency domain and spatial domain. In the frequency domain, a spectrum isolation scheme based on guardband is designed. In the spatial domain, a spatial stream isolation scheme based on service grouping is designed. Then, an isolation resource allocation method based on improved KM algorithm is proposed to realize the optimization of multi-service isolation. The simulation results show that the proposed communication isolation scheme can realize the communication isolation of underground pipe gallery with lower resource cost.
