Moving between access points and connecting to the best signal.
Wi-Fi roaming , here’s an example. Whenever we visit a mall and connect to its wireless network ,we are confidant that this connection will work throughout the mall no matter which block or floor you are on. Our phone disconnects from the AP with weak signal and reconnects to one with stronger signal. Since all these APs use the same SSID and security we don’t have to manually connect to them.
Wi-Fi roaming is triggered by the client device(Our phone or laptop) which decides when to disconnect and reconnect. Some devices are quick while some take long for this process which eventually halts the connectivity.
Wireless Network Virtualization is the technology which supports seamless roaming. Being costly its only used by large enterprises.Tags: wifi roaming
