AI roaming is a roaming function on the basis of smart roaming. It improves link quality during STA roaming by improving roaming sensitivity so that signals for STAs are good during roaming. Additionally, AI roaming collects information, such as STA roaming thresholds and roaming steering policies, to generate roaming profiles for each type of STAs, thereby improving the roaming success rate and further enhancing STAs' roaming experience.
Issues of Traditional WLAN Roaming and Smart Roaming
Traditional WLAN Roaming
On a WLAN, users require mobile communication. The signal coverage of a single AP, however, is limited. As such, users often move from the coverage area of an AP to that of another AP. To prevent network interruptions while users move between different APs, the concept of WLAN roaming is introduced.
WLAN roaming is a process wherein a station (STA) — when moving to the boundaries between two APs — associates with the new AP and disconnects from the original AP, during which connections are not interrupted. Simply put, WLAN roaming is similar to cell handover for a mobile phone. When a mobile phone moves from the coverage area of a base station to that of another base station, the mobile phone still enjoys uninterrupted and seamless call experiences.
