Introduction to the Client Adapters
Introduction to the Client Adapters
The Cisco Aironet Wireless LAN Adapters, also referred to as client adapters, are radio modules that
provide transparent, wireless, data communications between fixed, portable, or mobile devices and other
wireless devices or a wired network infrastructure. The client adapters are fully compatible when used
in devices supporting Plug-and-Play (PnP) technology.
The primary function of the client adapters is to transfer data packets transparently through the wireless
infrastructure. The adapters operate similarly to a standard network product except that the cable is
replaced with a radio connection. No special wireless networking functions are required, and all existing
applications that operate over a network will operate using the adapters.
This document covers four types of client adapters:
Refer to the “Radio Antenna” section on page 1-3 for antenna differences between these adapters.
