If using 802.11g then 30 - 35 clients could be connecting using Ruckus as long as the encryption is set to AES and not TKIP, this can be an unmanaged AP and then a controller could be added later to make this into a managed device with multiple AP's being used.
Ruckus use beamforming, which mitigates sources of interference which in turn keeps a signal to noise ratio (SNR) at a gain for clients connections resulting in much more reliable concurrent client connections.
