The wireless networks of individual devices overlap in home networks with a wireless router (for example FRITZ!Box) and one or more wireless repeaters (for example FRITZ!Repeater). 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 referred to 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 to a different wireless network. 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 all wireless devices support wireless roaming. Information on the range of functions offered by other wireless devices can be obtained from the respective manufacturer.

Note:All FRITZ!WLAN Sticks support wireless roaming.
