Abstract
In a Wireless Local Area Network (WLAN) and a method of transmitting a frame in the WLAN, mode information and an available data transfer rate of each wireless terminal located within a coverage of an Access Point (AP) are collected. A determination is made as to whether or not the AP transmits a Clear To Send (CTS) frame depending upon an existence of wireless terminals corresponding to the collected mode information before the AP transmits a data frame to at least one wireless terminal. A data transfer rate of the CTS frame is adjusted based on the collected available data transfer rate of each of the wireless terminals to transmit the CTS frame at the adjusted data transfer rate. Therefore, both the stability and the bandwidth effectiveness may be enhanced.
