Page 18: Introduction To The Client Adapters

Introduction to the Client Adapters Introduction to the Client Adapters The Cisco Aironet 340 and 350 Series Wireless LAN Client Adapters are 30- and 100-milliwatt (mW) 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.
Page 19: Hardware Components

IEEE 802.11b-compliant client devices in ad hoc (or peer-to-peer) mode or with Cisco Aironet 340, 350, 1100, and 1200 Series Access Points (with a 2.4-GHz radio) and other IEEE 80211b-compliant infrastructure devices in infrastructure mode. They are approved for indoor and outdoor use.
Page 20: Software Components

Client Utilities Two client utilities are available for use with Cisco Aironet client adapters: Aironet Client Utility (ACU) and Wireless Login Module (WLM). These utilities are optional applications that interact with the radio firmware to adjust client adapter settings and display information about the adapter. The client utilities and online help files are installed with the driver.
