ERRATA:
Confirmed errors:
{47} Figure 3-17;
The NAV for the RTS in Figure 3-17 says: "RTS=3xSIFS + Data + ACK", it should
include the CTS time and say: "RTS=3xSIFS + CTS + Data + ACK"
AUTHOR: it is correct. Please post it as a confirmed errata.
In case you want a reference, it's the last paragraph of section 7.2.1.1 of 802.11-1999:
"The duration value is the time, in microseconds, required to transmit the pending data or
management frame, plus one CTS frame, plus one ACK frame, plus three SIFS intervals.
If the calculated duration includes a fractional microsecond, that value is rounded up to
the next higher integer."
{191} Figure 10-26;
The HR/DSSS PLCP framing diagram shows the length and CRC fields to be a mixture
of 8 and 16 bits. Whereas the standard specifies them as all 16 bits.
AUTHOR: Yes, that is correct. Both the length and CRC fields should be 16 bits.
There are three changes necessary--I did get the CRC field length right in the "short
preamble" bar at the bottom of the figure, but the length field is wrong. Both the CRC
and length field are wrong in the "long preamble" bar at the top.
