Systems, methods, apparatuses, and computer program products for feeder link data transport are provided. For example, baseband in-phase and quadrature (IQ) data may be processed at the transmitter and receiver of the feeder link. The orthogonal frequency division multiplexing (OFDM) waveform used in a beam may be modified for transmission over the feeder link. For example, the waveform may have a wider subcarrier spacing (SCS) and may fill an enlarged bandwidth than otherwise with a feeder link.
