PD-MRC (Polarization Diversity – Maximal Ratio Combining) is a patented RUCKUS technology that enhances Wi-Fi signal reception by listening to client transmissions on both the horizontal and vertical polarization planes . This approach helps overcome signal degradation caused by multipath, reflections, and client device orientation.
According to the RUCKUS One Online Help and RUCKUS AI technical documentation , PD-MRC dynamically selects and combines the signal from both polarization domains to maximize the received signal-to-noise ratio (SNR). This technology works synergistically with BeamFlex , RUCKUS’s adaptive antenna system, to provide optimal signal gain and link reliability per client.
SmartCast is used for traffic prioritization and QoS management, ChannelFly handles dynamic channel selection using machine learning, and Tx Beamforming optimizes transmit signal direction. However, none of these specifically analyze both horizontal and vertical planes simultaneously.
Therefore, PD-MRC is the correct answer—it provides improved reception performance and overall RF robustness, especially for mobile clients in variable orientations.
