Method for enhancing transfer rate using DLP and multi-channel in DCF-based wireless LAN network, and wireless network system thereof

The present invention relates to a wireless communications infrastructure (Infrastructure) scheme DLP and the multi-set a new MAC frame format for using a channel, and by using this to reduce the competition in the station between (Station) to increase the hourly rate apparatus and method relate to. Wireless network system according to an embodiment of the present invention, DLP channel mode, the first radio station and the recording and the access point to the available channel number to the DLP request frame to transmit the recorded DLP request frame to the access point and the access point for forwarding the request frame to the receiving station, the DLP response frame for the forwarded DLP request frame via the access point and a second wireless station for transmitting to the first wireless station, the first radio station is characterized in that it transmits data to the second radio station via a channel corresponding to the channel number in accordance with the DLP channel mode. DLP (Direct Link Protocol), MAC (Media Access Control), the channel (Channel), AP (Access Point), BSS (Basic Service Set), CSMA / CA (Carrier Sense Multiple Access / Collision Avoidance)
