Which WLAN devices support roaming

9

Fat APs do not support WLAN roaming.

AC+Fit AP networking support WLAN roaming. V200R003 and earlier versions support only intra-AC roaming, while V200R005 and later versions support both intra-AC and inter-AC roaming.

Depending on whether a STA roams within the same subnet, WLAN roaming is categorized as Layer 2 roaming (on the same subnet) and Layer 3 roaming (on different subnets).

Layer 2 roaming is classified into fast roaming and non-fast roaming according to security policies used by STAs. Only when the security policy is WPA2-802.1x and STAs support fast roaming technology, fast roaming can be achieved.

WLAN roaming
WLAN roaming allows STAs to move within the coverage areas of APs belonging to the same ESS with nonstop service transmission. The most obvious advantage of WLAN networks is that a STA can move within a WLAN network without physical media restrictions. WLAN roaming allows STAs to move within a WLAN network without service interruption. An ESS includes multiple APs. When a STA moves from an AP to another, WLAN roaming ensures seamless transition of STA services between APs. WLAN roaming has the following advantages: - Retains STAs' IP addresses. After roaming, STAs can still access the initially associated WLAN network and retain their services. - Avoids packet loss or service interruption caused by long-term authentication.
