HR/DSSS PHY: High Rate / Direct Sequence Spread Spectrum Physical Layer

High Rate/Direct Sequence Spread Spectrum Physical Layer (HR/DSSS PHY) is the enhanced physical layer defined by IEEE 802.11b which supports data transfer at up to 11Mbps. Unlike the earlier versions of IEEE 802.11 which supported data rates of up to 2Mbps, HR/DSSS uses complementary code keying which divides the chip stream into a number of 8-bit code symbols.
