wireless mesh network

Since AVM has started to offer wireless mesh network capabilities in their products through software updates I started to roll it out in our house.

Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent. If nodes constantly or frequently move, the mesh spends more time updating routes than delivering data. In a wireless mesh network, topology tends to be more static, so that routes computation can converge and delivery of data to their destinations can occur. Hence, this is a low-mobility centralized form of wireless ad hoc network. Also, because it sometimes relies on static nodes to act as gateways, it is not a truly all-wireless ad hoc network.

With the rather complex physical network structure and above-average number of wireless and wired clients the task wasn’t an easy one.

To give an impression of what is there right now:

So there’s a bit of almost everything. There’s wired connections (1Gbit to most places) and there is wireless connections. There are 5 access points overall of which 4 are just mesh repeaters coordinated by the Fritz!Box mesh-master.

There’s also powerline used for some of the more distant rooms of the mansion. All in all there are 4 powerline connections all of them are above 100 Mbit/s and one even is used for video streaming.

All is managed by a central Fritz!Box and all is well.

Like without issues. Even interesting spanning-tree implementations like from SONOS are being properly routed and have always worked without issues.

The only other-than-default configuration I had made to the Fritz!Box is that all well-known devices have set their v4 IPs to static so they are not frequently switching around the place.

How do I know it works? After enabling the Mesh things started working that have not worked before. Before the Mesh set-up I had several accesspoints independently from each other on the same SSID. Which would lead to hard connection drops if you walked between them. Roaming did not work.

With mesh enabled I’ve not seen this behavior anymore. All is stable even when I move actively between all floors and rooms.
