Introduction to the Client Adapters Chapter 1 Product Overview and Installation Introduction to the Client Adapters The Cisco Aironet IEEE 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) are radio modules that provide wireless data communications among fixed, portable, and mobile devices within both wireless and wired network infrastructures. 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 through the wireless infrastructure by communicating with other clients or with access points that are connected to a wired LAN. The adapters operate similarly to a standard network product except that radios rather than Ethernet cables make the connection to the wire. No special wireless networking functions are required, and all existing applications that operate over a network can operate using the adapters. This document covers the two client adapters described in Table 1-1.

Introduction to the Client Adapters
The Cisco Aironet IEEE 802.11a/b/g Wireless LAN Client Adapters (CB21AG and PI21AG) are radio
modules that provide wireless data communications among fixed, portable, and mobile devices within
both wireless and wired network infrastructures. 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 through the wireless infrastructure
by communicating with other clients or with access points that are connected to a wired LAN. The
adapters operate similarly to a standard network product except that radios rather than Ethernet cables
make the connection to the wire. No special wireless networking functions are required, and all existing
applications that operate over a network can operate using the adapters.
This document covers the two client adapters described in
Table 1-1
