The R730 doesn't yet have SmartMesh support on any Ruckus controller platform. However we are expecting the feature to be included in an update in the near future. Unfortuantely I don't have any timescales available.
The SmartZone controller platform will almost certainly be the first platform to support the SmartMesh feature for the R730 when it becomes available.
If your requirement is urgent then the next AP in terms of performance is the R720, an 802.11ac Wave2 4x4:4 high-performance AP with a multi-gig Ethernet port: https://www.ruckuswireless.com/products/access-points/ruckus-indoor/ruckus-r720
I hope the above information helps.
