Embodiment Construction
[0036] The present invention can be implemented in the wireless network card through firmware, or in the driver program of the wireless network card. The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples.
[0037] (1) Frame format
[0038] The RTS / CTS frame format adopted by the present invention is slightly different from the standard IEEE802.11 protocol, and a new RES frame is added at the same time.
[0039] (1) RTS frame format
[0040] The RTS frame format that the present invention adopts is as image 3 shown.
[0041] (2) CTS / RES frame format
[0042] The CTS / RES frame format that the present invention adopts is as Figure 4 shown.
[0043]In IEEE802.11, there are 6 bits in "Frame Control" used to identify the frame type. The RES frame is not defined in the standard, but the DATA / ACK frame format adopted by the present invention is consistent with the IEEE802.11b standard.
