Description: Specifies the channel width used for transmitting the signal. This value is expressed in Hz.

If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211AG_OFDM, the channel bandwidth must be equal to 20 MHz.

If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211J_OFDM, the channel bandwidth must be equal to 10 MHz or 20 MHz.

NIWLANG_VAL_STANDARD_80211P_OFDM, NIWLANG_VAL_STANDARD_80211G_DSSS_OFDM, the channel bandwidth must be equal to 5 MHz, 10 MHz, or 20 MHz.

If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211N_MIMO_OFDM, the channel bandwidth must be either 20 MHz or 40 MHz.

If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211AC_MIMO_OFDM or NIWLANG_VAL_STANDARD_80211AX_MIMO_OFDM, the channel bandwidth must be equal to 20 MHz, 40 MHz, 80 MHz, 160 MHz.

If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211AH_MIMO_OFDM, the channel bandwidth must be equal to 1MHz, 2 MHz, 4 MHz, 8 MHz, or 16 MHz.

If you set the NIWLANG_STANDARD attribute to NIWLANG_VAL_STANDARD_80211AF_MIMOOFDM, the channel bandwidth must be equal to 6 MHz, 7 MHz or 8 MHz.

For OFDM signals, channel bandwidth determines the number of pilot and data subcarriers used. The toolkit ignores the NIWLANG_CHANNEL_BANDWIDTH attribute for other values of the NIWLANG_STANDARD attribute.
