Hi,
usually the Error Model is independent of the MAC itself. If the
Error Model determines that a packet is erroneous, it just sets the
error flag (struct HDR_CMN) of the packet. This field is evaluated by
MAC and the (same) actions are taken in the 11e as well 11 model if
the packet is marked accordingly.
Actually, what kind of drops did you observe in the trace for the
legacy model that do not appear for 11e?
Are parameters for both models similar? If the settings are
different ( e.g., 11a/b/g, RTS/CTS enabled or disabled etc.) also the
packet loss rate might vary greatly.
Best regards,
Sven
