Raghu. In an 802.11 infrastructure network, the two stations HAVE to communicate through the AP. There is no provision in the protocol for two stations to talk directly to each other even when they are part of the same network. So if s1 wants to send data to s2, it has to first send data to the AP and the AP will send data to s2. Even if s1 decides to use RTS/CTS to protect its transfer, it will only exchange the RTS/CTS frames with the AP. s2 won't even know that the data came from within the network. The 802.11e (QoS enhancements) spec updates the MAC protocol and allows for two stations to directly communicate with each other but only if the AP allows it. However, none of the currently deployed systems support this feature. Regards, - Harshal ------------------------ Yahoo! Groups Sponsor --------------------~--> Fair play?
