A.Lossless roaming is achieved through technical optimization or collaborative technology to meet business requirements such as delay and packet loss, ensure business continuity, and perform roaming switching without awareness.

B.In traditional roaming, when the terminal gradually moves away from the associated AP, it senses that the signal strength gradually decreases, and interacts with the presence of surrounding APs through Probe messages. When the terminal's signal reaches the roaming threshold, the terminal triggers the roaming to complete the AP. switching

C.802.11r fast roaming uses the FT (Fast BSS Transition) function to omit the 802.1X authentication and key negotiation intermediate re-authentication process during user roaming.

D.AI roaming is based on AI technology learning terminal roaming portrait, differentiated guided roaming
