C H A P T E R 1 Product Overview This chapter describes the Cisco Aironet Wireless LAN Client Adapters and illustrates their role in a wireless network.
Chapter 1 Product Overview Introduction to the Client Adapters Introduction to the Client Adapters The Cisco Aironet Wireless LAN 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.
Chapter 1 Product Overview Hardware Components Note In the first three product model numbers, the first x represents the client adapter series (340 or 350), and the second x indicates the wired equivalent privacy (WEP) level of the card, where 0 = no WEP capability, 1 = 40-bit WEP, and 2 = 128-bit WEP. If the last two product model numbers contain K9, the card is 128-bit WEP capable.
Chapter 1 Product Overview Hardware Components Radio Antenna The type of antenna used depends on your client adapter: • PC cards have an integrated, permanently attached diversity antenna. The benefit of the diversity antenna system is improved coverage. The system works by allowing the card to switch and sample between its two antenna ports in order to select the optimum port for receiving data packets.
Chapter 1 Product Overview Software Components Software Components The client adapter has three major software components: radio firmware, a driver, and client utilities. These components are installed together by running a single Install Wizard file that is available from Cisco.com.
Chapter 1 Product Overview Software Components Client Utilities Two client utilities are available for use with Cisco Aironet client adapters: Aironet Client Utility (ACU) and Aironet Client Monitor (ACM). These utilities are optional applications that interact with the radio firmware to adjust client adapter settings and display information about the adapter. ACU enables you to create configuration profiles for your client adapter and perform user-level diagnostics.
Chapter 1 Product Overview Software Components The title bar at the top of the Aironet Client Utility screen shows the profile that is being used by the client adapter. The status bar at the bottom of the Aironet Client Utility screen reflects the current state of your client adapter.
Chapter 1 Product Overview Network Configurations Using Client Adapters Buttons on the ACU Screens The buttons on the ACU screens are used to perform specific functions. Table 1-2 describes the most common buttons.
Chapter 1 Product Overview Network Configurations Using Client Adapters Ad Hoc Wireless LAN An ad hoc (or peer-to-peer) wireless LAN (see Figure 1-2) is the simplest wireless LAN configuration. In a wireless LAN using an ad hoc network configuration, all devices equipped with a client adapter can be linked together and communicate directly with each other. The use of an infrastructure device, such as an access point, is not required.
Chapter 1 Product Overview Network Configurations Using Client Adapters Wireless Infrastructure with Workstations Accessing a Wired LAN A microcellular network can be created by placing two or more access points on a LAN. Figure 1-3 shows a microcellular network with workstations accessing a wired LAN through several access points.

CSMA Carrier sense multiple access. A wireless LAN media access method specified by the IEEE 802.11 specification. cyclic redundancy check (CRC) A method of checking for errors in a received packet.
Glossary F file server A repository for files so that a local area network can share files, mail, and programs. firmware Software that is programmed on a memory chip and kept in a computer’s semi-permanent memory. fragmentation threshold The size at which packets are fragmented and transmitted a piece at a time instead of all at once. The setting must be within the range of 64 to 2312 bytes. full duplex A means of communication whereby each node receives and transmits simultaneously (two-way).
Glossary L LEAP, or EAP-Cisco Wireless, is the 802.1X authentication type that is available for use with operating systems that do not have EAP support. Support for LEAP is provided in the client adapter’s firmware and the Cisco software that supports it, rather than in the operating system. With LEAP, a username and password are used by the client adapter to perform mutual authentication with the RADIUS server through an access point.
Glossary R radio channel The frequency at which a radio operates. range A linear measure of the distance that a transmitter can send a signal. receiver sensitivity A measurement of the weakest signal a receiver can receive and still correctly translate it into data. RF Radio frequency. A generic term for radio-based technology. roaming A feature of some access points that allows users to move through a facility while maintaining an unbroken connection to the LAN.
Glossary UNII 1 A UNII band dedicated to in-building wireless LAN applications. UNII 1 is located at 5.15 to 5.25 GHz and allows for a maximum transmit power of 40 mW (or 16 dBm) with an antenna up to 6 dBi. UNII 1 regulations require a nonremovable, integrated antenna. UNII 2 A UNII band dedicated to in-building wireless LAN applications. UNII 2 is located at 5.25 to 5.35 GHz and allows for a maximum transmit power of 200 mW (or 23 dBm) with an antenna up to 6 dBi.
