*The Basic Rate Set contains the rates that all devices in the cell must support; it is a sub-set of the Transmit Rate Set. All control, multicast, and broadcast packets are transmitted using one of the Basic Rates (as defined by the IEEE 802.11 standards). The AP software refers to this parameter as the Multicast Rate within the Command Line Interface (CLI).
