H500 will mesh with any other Ruckus AP like a T300, and will work like any regular wired AP, broadcasting SSIDs on 2.4g and 5g and also providing wired Ethernet.
In fact, this is true for all Ruckus APs except the R300 series, you can mix and match APs as you wish.
You can even use an AP as your client mesh and wire another AP to it. For example, say you have T300s on lampposts but the signal inside the cottage isn't strong enough to form a mesh link. You can install a second T300 on the roof of the cottage and pull a wire from the roof to the H500 in the living room. Again all the APs will work as normal APs. The T300 on the cottage's ceiling will even allow other Mesh APs to connect to it wirelessly... It's extremely flexible.
