This is the error model for the layered IEEE 802.11 OFDM PHY infrastructure (IEEE 802.11-2012, Clause 18). OFDM means that the physical layer uses OFDM modulation.

The Ieee80211OfdmErrorModel, depending of the level of detail (see: Ieee80211LayeredOfdmTransmitter and Ieee80211LayeredOfdmReceiver), produces erroneous bits, symbols, samples or just simply determines whether a packet is erroneous or not.

The error model has built-in methods to approximate the corresponding error rates as a function of signal-to-noise ratio, bandwidth and other characteristics of the radio channel and the OFDM subcarrier modulations.

If you don't want to use these approximations you can set your own error rates for the signal (IEEE 802.11-2012, 18.3.4) and data field (18.3.5).
