This chapter considers the recently successful IEEE 802.11b standard for high-performance wireless Ethernet and a proposed extension that provides for 22 Mbit/s transmission. IEEE 802.11 sets standards for wireless Ethernet or wireless local area networks. The chapter describes the history of the IEEE 802.11 standards and the market opportunities in the wireless Ethernet field. The chapter gives a brief description of the Medium Access Control (MAC) layer and then presents details about the physical layer methods, including coding descriptions and performance evaluations. The chapter also discusses the role and limitations of spread spectrum communications in wireless Ethernet. A comparison in terms of range versus rate with several alternatives is presented.
