-The MAX2829 implements a "MIMO mode", which keeps the PLL running in the Standby state. By keeping the PLL active the phase offset between multiple MAX2829s sharing a reference clock is held constant across Tx->Rx and Rx->Tx state transitions. The radio_controller driver enables MIMO mode my default.
+The MAX2829 implements a "MIMO mode", which keeps the PLL running in the Standby state. By keeping the PLL active the phase offset between multiple MAX2829s sharing a reference clock is held constant across Tx->Rx and Rx->Tx state transitions. MIMO mode is required to support PHY designs which use explicit calibration or feedback of phases between antennas (like beamforming). MIMO mode is not required to support PHY designs which explicitly train each spatial path with every transmission (like Alamouti STBC). The radio_controller driver enables MIMO mode by default.
