    Wireless LAN(WLAN) is now widely used in local environments such as companies, universities, and hospitals due to the convenience of mobile terminals. But, the WLAN standard is not internationally adopted yet, and some inefficiency remains to be solved. In this paper, the use of sliding window control is suggested to improve throughput of the WLAN. It uses separate channel for acknowledge signals and thus save wasted time in Stop-and-Wait mechanism. WLAN transmit data by spread spectrum technique in S-band. Either channel in I-band or M-band can be used for acknowledge signal. From the simulation results, it is projected that the system throughput can be improved by 30% using suggested flow control mechanism in WLAN.
