... of one symbol provides 24 bits of data. At the highest data rate of 54 Mbps, 216 bits of data are recovered per symbol. From our analysis, it is evident that intercepting the first few symbols of a packet is sufficient for obtaining relevant header information. For example, consider the transmission ...
