The Institute of Electrical and Electronics Engineers (IEEE) has developed 802.11a, a new specification that represents the next generation of enterprise-class wireless LANs. Among the advantages it has over current technologies are greater scalability, better interference immunity, and significantly higher speed, up to 54 Mbps and beyond, which simulta-neously allows for higher bandwidth applications and more users. This paper provides an overview, in basic terms, of how the 802.11a specification works, and its corresponding benefits.
