No matter whether you have a big apartment, house with several floors, or a garden - mesh with FRITZ! brings fast and stable wireless LAN to every corner of your home. Simply add additional FRITZ! products to your home network, for example FRITZ!WLAN Repeater and FRITZ!Powerline with wireless LAN, and the FRITZ!Box meshes the individual wireless networks to form a large wireless LAN.

You can cascade several Mesh Repeaters in the Mesh. This type of cascading makes it possible for you to extend your home network in a specific direction beyond the Wi-Fi range of a Mesh Repeater.
This means that not only can you connect your FRITZ!Repeater with the FRITZ!Box (Mesh Master), you can also connect it with an already existing Mesh Repeater. It does not matter whether the Mesh Repeater is another FRITZ!Repeater, a FRITZ!Box, or a FRITZ!Powerline adapter.
