This shows a typical net data transfer rate of around 20 mb/s through two hops (non-turbo no compression) with all nodes on the 5.8 Ghz band.

We've done a fair number of these too, by adding a second radio on 2.4 for wifi access on the back of our 5Ghz surveillance networks. The biggest issue has been that many of the multi-tenant facilities have onerous long-term (e.g. 3-year) contracts in place with Comcast that have to lapse
