Bandwidth Allows selection of the bandwidth (BW), in MHz, of the RF network. Allowable
options are 10 MHz, 20 MHz (Default) and 40 MHz.
If maximizing throughput at shorter distance is of primary importance, then larger bandwidth of
40 MHz may be more appropriate.
Both Master and Slave units must be configured with the same Bandwidth setting.
