Abstract: The medium access control (MAC) and physical characteristics for wireless local area
networks (LANs) are speciTed in this standard, part of a series of standards for local and metropolitan area networks. The medium access control unit in this standard is designed to support physical
layer units as they may be adopted dependent on the availability of spectrum. This standard contains three physical layer units: two radio units, both operating in the 2400D2500 MHz band, and
one baseband infrared unit. One radio unit employs the frequency-hopping spread spectrum technique, and the other employs the direct sequence spread spectrum technique.
