The Distance Between APs must be set before the Multicast Rate.
NOTE:
There is an inter-dependent relationship between the Distance
between APs and the Multicast Rate. In general, larger systems
operate at lower average transmit rates.
Distance between APs Multicast Rate
Large 1 and 2 Mbits/sec
Medium 1, 2, and 5.5 Mbits/sec
Small 1, 2, 5.5 and 11 Mbits/sec
