This object is used to configure the multicast rate, but it is dependent on the type of wireless NIC. The value of this object is given in 500 Kbps units. This object can be configured to one of the values defined by the supported multicast rates objects (oriWirelessIfSupportedMulticastRates). For 802.11b Wireless NICs: This object identifies multicast rate of the wireless interface. This is dependent on the distance between APs. When the distance between APs object is set to small, minicell, or microcell the multicast rates can be set to 11 Mbit/s (22 in 500 Kbps units), 5.5 Mbit/s (11), 2 Mbit/s (4), and 1 Mbit/s (2). When this object is set to medium, the allowed rates are 5.5 Mbit/s (11), 2 Mbit/s (4), 1 Mbit/s (2). When this object is set to large, then the multicast rates can be set to 2 Mbits/s (4) or 1 Mbits/s (2). The default value for this object should be 2 Mbits/sec (4). For 802.11a, g, and a/g Wireless NICs: This object is used to set the multicast rate for beacons, frames used for protection mechanism (CTS), and other multicast and broadcast frames.
