What is Direct-Sequence Spread Spectrum (DSSS) Technology?
Direct-Sequence Spread-Spectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip. The longer the chip, the greater the probability that the original data can be recovered, however, the more bandwidth required. Even if one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can recover the original data without the need for retransmission. DSSS appears as low-power wideband noise to other receiver, and is ignored by most narrowband receivers.
