Basic (default)?Allows transmission at this rate for all packets, both unicast and multicast. At least one data rate must be set to Basic.The slowest basic rate is the rate that 802.11 management packets are sent. It is generally thought that management packets should be sent a the lowest rate. But, these are application devices and should be set to best

fit the application(s).
