Line 15:
In contrast, [[frequency-hopping spread spectrum]] pseudo-randomly retunes the carrier, instead of adding pseudo-random noise to the data, which results in a uniform frequency distribution whose width is determined by the output range of the [[Pseudo-random number|pseudo-random]] number generator.
==Uses of Direct-Sequence Spread Spectrum==
DSSS is often used for devices such as 2.4 and 5.8 GHz cordless phones. It is also a part of the [[802.11]] [[802.11b|b]] and [[802.11g|g]] standards. Note that in the original [[802.11]] standard, either [[FHSS]] or [[DSSS]] may be used.
