Presence of legacy clients will limit the performance improvement for 802.11n WLANs. Legacy clients will continue to operate at legacy speeds occupying the medium for longer intervals per frame transmission. Further, legacy clients associating with an 802.11n AP will trigger the HT-protection mode in this AP leading to additional overhead. Both these factors will reduce the net throughput of the 802.11n devices associated with the same AP.
