This format is originally defined for OFDM as a 4 bit
|
|
field but the 5th bit was added to indicate 11b formatted
|
|
frames. In the standard bit [4] is specified as reserved.
|
|
For 11b frames this L-SIG is transformed in the PHY into the
|
|
11b preamble format. The following are the rates:
|
|
|
|
<enum 8 ofdm_48_mbps> 64-QAM 2/3 (48 Mbps)

length
|
|
|

The length indicates the number of octets in this MPDU.

Note that when using mixed mode 11n preamble this length
|
|
provides the spoofed length for the PPDU. This length
|
|
provides part of the information to derive the actually PPDU
|
|
length. For legacy OFDM and 11B frames the maximum length

11a/n/ac TX: This field provides even parity over the

first 18 bits of the signal field which means that the sum

of 1s in the signal field will always be even on

field from the L-SIG symbol for the current packet.
