Chapter 1 Overview

Introduction to the Client Adapters

The Cisco Aironet Wireless LAN Ad apters , also refe rred to as client adapters, ar e radio mod ules 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- an d-Play ( PnP) techn ol ogy.

The primary function of the client adapters is to transfer data pack ets transparen tly through the wirele ss infrastructu re. Th e adap ter s operat e sim ilarly to a stan dard ne twork pr oduct exce pt that the ca ble is replaced with a radio connection. No special wireless networking functions are required, and all existing applications that operate over a network will operate using the adapters.

This document c overs thre e t ypes of clie nt a dap ters:

• PC card client adapter (also referred to as a PC card) – A PCMCIA card radio module that can be

inserted into a ny de vice eq uipped 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 sl ot . H o s t devices usually include hand -held or port able devices.

• PCI client adapter – A client adapter card radio module that can be inserted into any device

equipped with an empty PCI expan sion slot, suc h as a desktop compute r.

Refer to the “Radio Ante nna” secti on on page 1-3 for an tenn a differen ces be tween these adapt ers.

Introduction to the Client Adapter Software Components

The software components of the client adapter consists of a driver, firmware, and a client utility. These components work together to allow the client adapter to work properly in your workstation. Typically, the driver and client utility are designed for use with a specific operating system or a group of similar operating systems, while the firmware is designed specifically for the client adapter’s hardware and radio. The firmware controls the radio operations.

Chapter 1 Overview

Parts of the Client Adapter

The client adapte r firmware provides the inte rface between the radio and the driv er. The driver provides the interface between the client adapter firmware and the workstation’s operating system. The client adapter is installed as a network communications adapter on the workstation’s operating system.

The client utility interfaces to the operating system to allow you to configure, test, and monitor the operations of the client adapter on the wireless LAN. The client utility also allows you to load new firmware into the client adapter.

Terminology

Throughout this doc um en t, the fo llowing te rms a re u sed :

• client adapter – Refers to all three types of adapters

• PC card, LM card, or PCI client adapter – Refers to only a specific adapter

• workstati on (or station ) – Refers to a computing device with an installed client adapter

Parts of the Client Adapter

The client adapter is compose d of three major par ts: a radio, a radio ante nna, and t wo LEDs.

Radio

The client adapter contains a direct-se quence spread spectrum (DSSS) radio that operates i n the 2.4-GHz license-free Industrial Scientific Medical (ISM) band. The radio transmits data over a half-duplex radio channel oper ati ng at up t o 11 Mbps.

DSSS technology causes radio signals to be transmitted over a wide frequency range, using multiple frequencies simultaneously. The benefit of this technology is its ability to protect the data transmission from interfere nce . For examp le, i f a pa rti cul ar fre que ncy enc ou nt ers no ise or int erf er en ce o r bot h, enough redundancy is built into the signal on other frequencies that the client adapter is usually still successful in its transmission.

Radio Antenna

The type of antenna use d depends on you r clie nt adapte r:

• PC cards have an integrated, permanently attached diversity antenna. The benefit of the diversity

antenna system is improved coverage. The system works b y allowing the card to switch and sample between its two antenna ports in order to select the optimum port for receiving data packets. As a result, the card has a better chance of maintaining the radio frequency (RF) connection in areas of interference. The anten n a is ho u sed with in the sec tion of the card th at h angs o ut of the PC car d slot when the card is installed.

• LM cards are shipped without an antenna; however, an antenna can be connected through the card’s

external connector. If a snap-on antenna is used, it should be operated in diversity mode. Otherwise, the antenna mode used should correspond to the antenna port to which the antenna is connected.

• PCI client adapters are shipped with a 2-dBi dipole antenna that attaches to the adapter’s antenna

connector. However, other types of antennas ma y be used . PCI cli ent adap ters can be operate d through the right ant enn a por t on ly.

A microcellular network ca n be create d by placing two or mo re access po ints on a LAN . Figure 1-2 shows a microcellular networ k with workstations accessing a wired LAN through several access points.

This configuration is useful with portable or mobile stations because it allows them to be directly connected to the wired network even while moving from one microcell domain to another. This process is transparent, and the connection to the f ile serv er or host is maintained witho ut disruption . The mobile station stays connected to an access point as long as it can. However, once the transfer of data packets needs to be retried or beacon s are missed, the stati on automatically sear ches for and associates to another access point. This process is referred to as seamless roaming.

Chapter 4 Security Features

Overview of Security Features

When you use your clie nt adap te r wi th t he M ac O S op er ati ng s yst em, y ou c a n prot ec t yo ur d ata as it is transmitted through your wireless network by encrypting it through the use of Wired Equivalent Privacy (WEP) encryption ke ys. W ith WEP encry ption, the transmitti ng devic e encrypts each packet with a WEP key, and the receiving device uses that same key to decryp t each packet.

The WEP keys used to encrypt and decrypt transmitted data can be statically associated with your adapter or dynamically created as part of the LEAP authentication process. The information in the sections below can help you t o de c ide w hich typ e of WE P keys you wa nt to u se. Dyn ami c WEP keys with LEAP offer a higher degree of security than static WEP keys.

WEP keys, whether static or dynamic, are either 40 or 128 bits in length. The 128-bit WEP keys contain more characters than the 40-bit keys and, therefore, offer a greater level of security.

Static WEP Keys

Each device (or profile) w ith in yo ur wi reless ne twork can be assign ed u p to fo ur stat ic WE P keys. If a device receives a packet that is not encrypted with the appropriate key (as the WEP keys must match in all devices that are to commu nicat e with each ot her), t he device disc ards th e packe t.

For the Mac OS X, the Static WEP keys are write-only and stored in an encrypted format (for security reasons) in your Macintosh; therefore, you canno t read them back. When the driver loads and reads the client adapter’s parameters, it also finds the static WEP keys, decrypts them, and stores them in vo lat ile memory on the client adapter. The WEP keys in the client adapter are temporary and they are lost when power to the adapter is removed or the Mac intosh is reboote d. Althoug h the keys in the cli ent adapt er are temporary, you do not need to re-enter them when you restore power or reboot because the keys are stored in your M aci nto sh.

For the Mac OS 9.x, the Stat ic WEP keys can be perm anently or temporarily stored in your client adapter . If the keys are temporarily stored in v olatile me mory, the keys will be lost wh en p ower is removed fr om your client adapter.

The client utility allows you to enable or disable static WEP and to add or change keys.

Dynamic WEP Keys with EAP

The new standard for wireless LA N securit y, as defined by the Institute of Electrical and Electr onics Engineers (IEEE), is called 802.1X for 802.11, or simply 802.1X. An access point that supports 802.1X and its protocol, Extensi ble Auth entica tion Protoc ol (EAP) , acts as th e interfac e betwee n a wireless client and an authentication server, such as a Remote Authentication Dial-In User Service (RADIUS) server, to which the access point communicates over the wired network.

The use of an 802.1X authenticat ion type, whic h is supported by the client an d the authenticatio n serve r , causes the foll owing to oc cur:

• After associating to the access point, the client does not gain access to the network until mutual

authentication between the client and the authentication server is successful.

• The client and authentication server derive the same dynamic WEP key.

• The authentication server sends the dynamic WEP key to the access point.

• For the length of a session, or time period, the access point and the client use the dynamic WEP key

to encrypt and decrypt all unicast packets that travel between the access point and the client.

Chapter 4 Security Features

Overview of Security Features

A Cisco Aironet client adapter running on the Mac OS operating system supports the following 802.1X authentication type:

• EAP-Cisco Wireless (or LEA P)

EAP-Cisco Wireless or LEAP

Support for EAP-Cisco Wireless or LEA P i s provide d in a Cisc o Ai rone t cli ent ad apte r’s firmware and the Cisco software that supports it. The RADIUS servers that support LEAP include Cisco Secure ACS version 2.6 and above and Cisc o A cce ss Registra r version 1. 7 and a bove.

LEAP is enabled or disab led usin g the clien t utility. When LEAP is enabled, the client adapter uses your LEAP username and password to perform mutual authentication with the RADIUS server through the access point. The username and password are stored in the client adapter’s volatile memory; therefore, they are temporary and need to be re-entered whenever the radio is turned off, the client adapter is removed, or the Macintosh is powered down.

Note In Mac OS 9. x, w he n y our c om pute r is rebo ot ed, a po p-u p m es sag e ap pear s to i nfo rm you t h at you

must use the client utility to enter your LEAP username and password.

Note In Mac OS X, when yo ur comp ut er i s reboo t ed, th e Wireless Networ k Log in scre en app ears a nd

prompts you to ent er y our L EAP use rname and p assword.

When you enable Network-EAP on you r access poin t and LE AP on your clie nt adapte r, authentication to the network occurs in the following sequence:

a. The client adapter associates to an access point and begins the authentication process.

Note The client adapter does not gain access to the network until the mutual authentication with

the authentication server is successful.

b. Communicating through the access point, the client adapter and the authentication server complete

a mutual authentication process, with the password being the shared secret for authentication. The password is never transmitted during the process.

c. If mutual authentication is successful, the client adapter and the authentication server derive a

dynamic, session-ba sed W EP key that is un ique.

d. The authentication server transmits the key to the access point using a secure channel on the wired

LAN.

e. For the length of a session, or a time period, the access point and the client adap ter use th is key to

encrypt or decrypt all uni cast packe ts that travel between the m.

Note Refer to the IEE E 802.1 1 Stand ar d for m ore in for mat ion on 802 .1X au then tic atio n a nd to the

Configuring Your Client Adapter

Power Save Mode Sets your client adapter to its opt imum power consum ption setting .

Default:C onsta nt Awake Mode (CAM)

Power Save Mode Description

Constant Aw ake Mode Keeps the client adapter powered up continuously

so there is little lag in message response time. Consumes the most power but offers the highest

throughput. Is r ecom mend ed for de sktop computers and devices that use AC power.

Fast Power Save Mode Switches between a PSP mode and CAM mode,

depending on network traffic. This mode switches to CAM when retrieving a large number of packets and switche s back to PSP after the pack ets are retrieved.

Is recommended when power consump tion is a concern but you need greater throughput than that allowed by Max PSP.

Maximum Power Save Mode

Causes the access point to buffer incoming messages for the client adapter, which wakes up periodically and polls the access point to see if any buffered messages are waiting for it. The adapter can request each message and then go back to sleep.

Conserves the most power but offers the lowest throughput. Is recomme nded for devices for which power consumption is the ultimate concern (such as small battery-p owered devices).

Configuring Your Client Adapter

Authentication Type Defines how your client adapter will attempt to authenticate to an access

point. Default: Open

Authentication Description

Open Allows your client adapter, regardless of its WEP

settings, to authenticate and attempt to communicate with an access point.

Shared Key Allows your client adapter to communicate only

with access points that have the same WEP keys. The access point sends a known unencrypted

“challenge packet” to the client adapter, which encrypts the pa cket and sen ds it ba ck to t he acce ss point. The access point attempts to decrypt the encrypted pac ket and se nd s a n au th en tic a tio n response packet indicati ng the suc cess or failur e of the decryption back to the client adapter.

Note If LEAP is enabled on your client adapter, Open is the only available option.

Note The Shared Key option is available only if the client adapter has been assigned a WEP key

and WEP is enable d. Ref er t o th e Chap ter 4, “Security Features” for instructions on setting a WEP key and enabling WEP.

Data Rate Specifies the rate at which you want your client adapter to transmit or

receive packets to or from access poi nts (in inf rastruc ture mo de) or othe r clients (in ad hoc mod e) .

The data rate must be auto or the same as the wireless dev ice with which you wish to communicate.

Default: Auto

Data Rate Description

Auto Uses the 11-Mbps data rate when possible but drops

to lower rates when neces sary. 1 Mbps Offers the greatest r ange but the lowest throughput. 2 Mbps Offers less range but greater throughput than the 1

Mbps Only option.

5.5 Mbps Offers less range but greater throughput than th e 2

Mbps Only option. 11 Mbps Offers the greatest throughpu t but the lowest range.
