Dual-CTS protection

The 802.11n amendment defines an operational mechanism that accounts for coexistence between 802.11n HT coverage cells and nearby legacy 802.11a/b/g coverage cells. When either an HT or non-HT station transmits a frame, the station first sends a request-to-send(RTS) frame to the HT AP.The AP will then reply with two clear-to-send (CTS) frames. One CTS frame is in the legacy non-HT format, while the other frame is in the HT format
