Simultaneous Dual Band WI-FI: The UniFi AC-Pro is up to 5X faster with Dual-Radio 3x3 11AC MIMO technology. It supports up to 300 Mbps, 2x2 MIMO for the 5 GHz band and up to 450 Mbps, 3x3 MIMO for the 2.4 GHz band. Optimal Performance Designed for Optimal RF Performance, this UniFi Controller collects feedback on full 5 GHz and 2.4 GHz channel interface. It offers band steering that pushes clients to faster interface-free, 5 GHz channels. It also minimizes problem-client effects on system performance by limiting their airtime access
