Publisher Summary This chapter provides an overview of wireless networking. Radio technologies that gave rise to wireless networking. Cisco provides a number of wireless networking products, from wireless access points (APs) that enable clients to function, to wireless bridges that connect networks over great distances. Cisco strives to provide a standard method of networking wireless via consistent interfaces for configuration and monitoring. Menus, commands, and Web interfaces can be used to configure any Cisco wireless network device. Cisco wireless AP and bridges have fairly large coverage areas. Coverage can be expanded with the use optional antennas, which can also compensate for obstructions and distance that would otherwise degrade wireless rates. This chapter provides an overview of the various antenna types, and their appropriate use. Almost all Cisco wireless products support the new security mechanisms; this is illustrated in the chapter.
