All Ruckus APs has Polarization Diversity Multi Ratio Combining. This MCR is not an specific feature but a set of them (some are proprietary some are part of the 802.11 standard) that at the end combines the signals from UEs to get the best performance.
Ruckus has many patents on this.
Note: On our outdoor APs, if you use 3rd party external antenna, PD-MRC may not work.
