Listen Interval indicates how long the station will be "sleeping" without listen to any Beacon transmitted by the AP's when the station enter in power save mode, those beacons includes the DTIM information. The relevant point here is that if we don't tuned properly these 2 attributes it could happen that when the AP transmit the DTIM letting the Station know that is some information in the buffers to be transmitted the Station could be not listening because the Listen Interval is so high for instance.
