* The raw speed reported by your wireless network adapter is ''not'' necessarily a reliable indicator of actual raw speed. The reason is that transmit speed fluctuates according to the wireless error rate, and when the wireless link is idle, unrealistic speed may be reported (since no errors are occuring when the wireless link is idle).

* Data can only flow on ''one'' wireless link in ''one'' direction at any one time, which means that the ''maximum data transfer rate will be well below half of the raw wireless network speed''.
