| Description: | Specifies the type of the guard interval (Cyclic Prefix) in an OFDM symbol. If you set the NIWLANA_DSSS_DEMOD_HEADER_DETECTION_ENABLED attribute to NIWLANA_VAL_FALSE, the toolkit uses the NIWLANA_GUARD_INTERVAL_TYPE attribute for performing OFDM demodulation measurements. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211N_MIMO_OFDM, the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_FOUR is 0.8 µs, and the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_EIGHT is 0.4 µs. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AC_MIMO_OFDM, the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_FOUR is 0.8 µs and the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_EIGHT is 0.4 µs. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AF_MIMO_OFDM, and the NIWLANA_CHANNEL_BANDWIDTH to 6 MHz or 7 MHz, the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_FOUR is 6 µs, and the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_EIGHT is 3 µs. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AF_MIMO_OFDM, and the NIWLANA_CHANNEL_BANDWIDTH to 8 MHz, the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_FOUR is 4.5 µs, and the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_EIGHT is 2.25 µs. If you set the NIWLANA_STANDARD attribute to NIWLANA_VAL_STANDARD_80211AX_MIMO_OFDM, the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_FOUR is 3.2 µs, the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_EIGHT is 1.6 µs and the NIWLANA_VAL_GUARD_INTERVAL_TYPE_ONE_BY_SIXTEEN is 0.8 µs.
