Ieee80211OfdmPhyHeader

class

The length field is a 12-bit integer indicates the number of octets in the PSDU that the MAC is currently requesting the PHY to transmit.

The rate field (18.3.4.2 RATE field) is a 4-bit integer carries information about the modulation and coding.

There are other fields which are not explicitly represented here, for e.g. Parity, Reserved, SERVICE, Pad Bits.

The PSDU field must be contained as an encapsulated packet.

This packet is intended to represent the whole PPDU frame in the IEEE 802.11 PHY. For detailed description, you may refer to 18.3.2 PLCP frame format, Figure 18-1—PPDU frame format in IEEE Std. 802.11-2012.
