ABSTRACT
The IEEE 802.11b specification represents one of three
wireless LAN standards developed by the Institute of
Electrical and Electronic Engineers. The original standard,
which was the 802.11 specification, defined wireless LANs
using infrared, Frequency Hopping Spread Spectrum
(FHSS), and Direct Sequence Spread Spectrum (DSSS)
communications at data rates of 1 and 2 Mbps. The rela-
tively low operating rate associated with the original IEEE
802.11 standard precluded its widespread adoption.
