a b s t r a c t IEEE 802.11 devices dynamically choose among different modulation schemes and bitrates for frame transmissions. This rate adaptation, however, is restricted only to unicast frames. Multicast (and broadcast) frames are constrained to use a fixed low bit-rate modulation, resulting in l
