WiFi Roaming occurs when a smartphone , tablet or other wireless client device moves outside the usable range of a WiFi router and connects to another WiFi router. Roaming can also happen when the quality or strength of the client’s received signal drops. The client device automatically roams from one router to another as needed to provide seamless connectivity.
WiFi roaming is a process that allows users to seamlessly transfer their wireless internet connection from one access point to another. This is particularly useful for those who require a constant and stable internet connection, such as those working remotely or using online applications that require a strong connection.
In essence, WiFi roaming works by allowing devices to automatically switch to the strongest available access point as they move between locations. This makes it possible to stay connected to the internet without having to manually reconnect to a different network every time you move out of range of your current access point. It can also help to ensure that you don’t experience interruptions to your internet connection during important tasks such as streaming video or downloading large files.
