out over time, which minimizes effects from interference
and degradation.
Most of the early 802.11 networks used the FHSS
scheme, which is simpler. Networks that used the DS-SS
scheme were more effective, but all the original 802.11
products had data rates of at most 2 Mbps, which limited
their usefulness.
In 1999,the IEEE issued the second and third physical
layers, IEEE 802.11a and IEEE 802.11b, at roughly the
same time. IEEE 802.11a operates in the 5-GHz band at
data rates up to 54 Mbps. IEEE 802.11b operates in the
2.4-Ghz band at 5.5 and 11 Mbps. Because 802.11b is eas-
ier to implement, it has yielded products first.
802.11b
IEEE 802.11b extends the IEEE 802.11 DS-SS scheme,
providing data rates of 5.5 and 11 Mbps through the use
of a more complex modulation technique.
