C H A P T E R Product Overview This chapter describes the Cisco Aironet CB21AG and PI21AG client adapters and illustrates their role in a wireless network. The following topics are covered in this chapter: • Introduction to the Client Adapters, page 1-2 Hardware Components, page 1-3 •...
Page 18: Introduction To The Client Adapters
Introduction to the Client Adapters 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 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”...
Page 19: Hardware Components
Infrastructure (UNII) frequency bands. The client adapters operate with other IEEE 802.11a or 802.11b/g-compliant client devices in ad hoc mode or with Cisco Aironet 340, 350, 1100, and 1200 Series Access Points and other IEEE 802.11a or 802.11b/g-compliant infrastructure devices in infrastructure mode.
Page 20: Software Components
The client adapters have two major software components: a driver and client utilities. These components are installed together by running a single executable Install Wizard file that is available from Cisco.com. This file can be run on Windows 2000 or XP and can be used only with CB21AG and PI21AG client adapters.
