PC Review take a look at the Netgear Orbi, an extremely powerful Mesh Wi-Fi solution which runs over a dedicated 1733Mbps 5Ghz backhaul:

"We've been using the Orbi for two months now, replacing a 2.4Ghz Draytek router + access point combo that worked well for several years. The previous setup had good range, but speeds were very limiting once you approached difficult to reach parts of the house. The reason we upgraded to Orbi was to avoid wiring in an Ethernet cable between the ground floor and 2nd floor of our house. The Orbi backhaul has a theoretical maximum throughput of 1733 Mbps, and although this won't be reached, it could at least go some way toward to competing with a hard wired 1000Mbps connection (and it's much, much easier to install)."
