What is wireless roaming and how does it work?
If you use a wireless router (for example FRITZ!Box) and one or more wireless repeaters (for example FRITZ!WLAN Repeater) in a home network, then the wireless networks (WiFi) of the individual devices overlap. If a smartphone, tablet, or other wireless device automatically switches from a wireless network with a weak signal to one with a stronger signal in such an environment, this is known as "wireless roaming".
The roaming behavior is not influenced by the router or the repeater. Instead, the wireless device itself decides to switch between wireless networks as soon as the values for signal strength and transmitting power fall below the limit defined by the manufacturer.
Network and data connections (for example VoIP calls, video streams, or downloads) are briefly interrupted every time a device switches between wireless networks. The duration of the interruption can be reduced to a minimum if routers and repeaters use identical wireless network names (SSIDs), network keys, and wireless channels.
Not every wireless device supports roaming. Refer to the respective manufacturer for information on other wireless devices' range of functions.
Note:All FRITZ!WLAN Sticks support wireless roaming.
