Introduction to the Wireless LAN Adapters
The Cisco Aironet Wireless LAN Client Adapters, also referred to as 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 adapters are fully compatible when used in
devices supporting Plug-and-Play (PnP) technology. Host devices can be any device equipped with a PC
Card Type II or Type III slot. These devices include:
• Desktop systems
• Portable laptops
• Notebook computers
• Personal digital assistants
• Pen based computers
• Other data collection devices
The primary function of the 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 can operate using the adapters.
The PC Card can also be built into peripheral devices such as printers to provide them with a transparent
wireless connection to a wired network.
This document covers three types of adapters:
• PC card client adapter (also referred to as a PC card)—A PCMCIA card radio module that can be
inserted into any device equipped with an external Type II or Type III PC card slot. Host devices can
include laptops, notebook computers, personal digital assistants, and hand-held or portable devices.
• LM card client adapter (also referred to as an LM card)—A PCMCIA card radio module that can be
inserted into any device equipped with an internal Type II or Type III PC card slot. Host devices
usually include hand-held or portable devices.
• PCI client adapter—A client adapter card radio module that can be inserted into any device equipped
with an empty PCI expansion slot, such as a desktop computer.
Refer to the “Radio Antenna” section on page 1-4 for antenna differences between these adapters.
