haven't had any need to do a mesh setup for wifi at all yet. I dont quite understand the appeal for a home.
A typical consumer "repeater" has only one set of radios and can't multi-task. It receives a packet, flips to transmit mode, then broadcasts that packet. By design, this will cut speed in half -- each time that a packet traverses a repeater. Mesh access points can simultaneously send and receive. The mesh attempts to find a minimum time path through the mesh. Traversing a mesh node implies a slight latency, not a wait for the whole packet to arrive before sending delay. If a node goes down, the mesh will work out a new topology.
The appeal is that one does not need to run wires and a wireless mesh will minimize the performance hit compared to the "repeater" approach. Of course, wired is always faster and more robust -- when practical. Mesh is a great solution for renters.
In the real world things are not quite as rosy as implied above: Here are some thoughts
My experience with mesh has been much better than with simple repeaters -- but I will always wire when practical. While I will encounter previously deployed repeater systems, I have only installed one "repeater" (at the customer's insistence because it was already onsite), but I regret that decision because it has caused trouble.
Some of the products will attempt to use dual band to work out a "backbone" scheme. This approach will avoid many of the collisions. and could improve roaming.Some further food for thought
