A probe request sent from a Wi-Fi 6E wireless client to the legacy access point is received by a Wi-Fi controller. To process, a Wi-Fi 6E access point for connection from the plurality of access points, proximate to the Wi-Fi 6E wireless client is selected for service. Reduced Neighbor Report (RNR) RNR information is collected about the Wi-Fi 6E access point by the access point the Wi-Fi 6E wireless client. The RNR information is transmitted to the legacy access point, wherein the legacy access point forwards the RNR information to the Wi-Fi 6E wireless client as part of a probe response sent responsive to the probe request. A subsequent probe request is detected, sent from the Wi-Fi 6E wireless client to initiate association with the Wi-Fi 6E access point using the RNR information.

This invention relates to the field of bridge monitoring and discloses a distributed wireless intelligent network sensing system for bridges, comprising: a sensing node module for distributed acquisition of multimodal raw signals at predetermined locations on the bridge; an edge aggregation module for receiving the damage feature data, constructing evidence sources by combining multi-source correlation data, and outputting hierarchical decision results; a cloud decision module for classifying the hierarchical decision results according to working conditions, generating adaptive early warning thresholds based on probability correction and dynamic threshold optimization, and executing hierarchical early warnings; and a wireless network transmission module for data interaction through a hybrid wireless network. By refining damage feature data through signal decomposition and interference removal, effectively filtering interference data through multi-source evidence fusion and hierarchical decision-making, and generating adaptive early warning thresholds adapted to different working conditions through working condition classification, probability correction, and dynamic threshold optimization, accurate identification and reliable early warning of bridge structural damage are achieved.

The present invention relates to a wireless system 100 running multiple applications simultaneously, for example for both lighting control and asset tracking. Nodes 200 included in the wireless system 100 are capable of operating in multiple communication modes, where each communication mode is according to a different communication technology. On the other hand, considering that some applications can have higher security requirements than others, one application can have a preferred communication mode that is different from another application. In view of this, a mode switching method is disclosed to help the nodes 200 to serve multiple concurrent applications in an efficient manner.
