IMPORTANT NOTE:
FCC Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment.
This device complies with FCC RF Exposure limits set forth for an uncontrolled environment, under 47 CFR 2.1093
paragraph (d)(2).
This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
Nortel declared that WLAN-Mobile Adapter 2202 is limited in CH1~11 by specified firmware controlled in USA from
2400~2483.5MHz.
Nortel declared that WLAN-Mobile Adapter 2202 has been disabled for operation in the USA in the 5.470~5.725 MHz
UNII band by specified firmware control.
This equipment has been SAR-evaluated for use in laptops (notebooks) with side slot configuration.
Exposure to Radio Frequency Radiation
The radiated output power of the Nortel Networks Wireless LAN Mobile Adapter 2202 radio is far below the FCC radio
frequency exposure limits. Nevertheless, the wireless radio shall be used in such a manner that the potential for human
contact during normal operation is minimized.
The Nortel Networks Wireless LAN Mobile Adapter 2202 radio operates within guidelines found in radio frequency
safety standards and recommendations, which reflect the consensus of the scientific community. Nortel Networks
therefore believes the internal wireless radio is safe for use by consumers. The level of energy emitted is far less than the
electromagnetic energy emitted by wireless devices such as mobile phones. However, the use of wireless radios may be
restricted in some situations or environments, such as aboard airplanes. If you are unsure of restrictions, you are
encouraged to ask for authorization before turning on the wireless radio.

Overview
Nortel Networks WLAN - Mobile Adapter 2202
configuration modes
You can configure the Nortel Networks WLAN - Mobile Adapter 2202 to work in
either infrastructure mode or ad hoc mode. For information on specifying the
configuration mode, see “Connecting to a network” on page 40.
Infrastructure (access point) mode
In infrastructure mode, devices communicate with each other through an access
point (AP). In this mode, wireless devices can communicate with each other as
well as with work stations, file servers, and other components on a wired network
(Figure 1). When one AP is connected to a wired network and a set of wireless
stations, it is referred to as a BSS (Basic Service Set).
In infrastructure mode, the wireless network adapter utilizes a BSS as a station
and communicates with other wireless stations and with the components in the
wired network through the access point.

Ad hoc mode
In ad hoc mode (Figure 2), wireless network adapters work within an independent
basis service set (IBSS) and all stations communicate directly with each other
without using an access point (AP). Ad-hoc mode is also called peer-to-peer
mode.
An ad hoc wireless LAN consists of a group of computers, each of which is
equipped with a wireless adapter card, that is connected by radio signals as an
independent wireless LAN.
In most cases, computers in an ad hoc wireless LAN automatically detect the
channel being used for the ad hoc network. When using ad hoc mode with the 2.4
GHz frequency range, you either can let the computer auto-detect the channel or
manually set the channel. When manually setting the channel, all computers in the
wireless LAN must be configured to the same radio channel.

Added support for Advanced Encryption Standard (AES)
The Nortel Networks WLAN - Mobile Adapter 2202 Utility enables you to create
and edit configuration profiles and to display various diagnostics information
pertaining to the Nortel Networks WLAN - Mobile Adapter 2202.
The Nortel Networks WLAN - Mobile Adapter 2202 introduces support for
Advanced Encryption Standard (AES) and associated infrastructure from 802.11i.
From the information element (IE) in the access point (AP) broadcast beacon, the
Mobile Adapter 2202 automatically detects which encryption mode (WPA-AES
or WPA-TKIP) is being used by the AP. The Mobile Adapter 2202 also supports
roaming from one AP that is using WPA_TKIP to another AP that is using
WPA-AES, and vice versa.

the utility uses to locate an access point to associate with and lets you specify the
order of the profiles it uses to scan for an access point. Once you have set up this
feature, you no longer have to manually activate a different profile when you
change locations; the auto profile feature does the work for you.

This feature is useful when you need to connect to the network from different
locations and you have created a profile with different settings for each location.
This feature applies only to profiles that have infrastructure specified as the
network type, and to profiles that specify only one SSID. In addition, if more than
one profile uses the same SSID, only one of those profiles can be added to the
Auto Selected Profiles list.
Note: The “Default” profile cannot be added to the Auto Selected
Profiles list.

Configuring network security
Overview
This chapter explains how to use the Nortel Networks WLAN - Mobile Adapter
2202 Utility to configure network security. While using the Mobile Adapter 2202,
encrypting data can protect it as it is transmitted through the wireless network.
The Nortel Networks WLAN - Mobile Adapter 2202 Utility lets you use one of
the following connection profile options:
•
WPA security
This option enables the use of Wi-Fi Protected Access (WPA). This option
requires network administration support. This option includes the EAP (with
dynamic WEP keys) security protocols: EAP and PEAP.
WPA is a standards-based, interoperable security enhancement that provides
data protection and access control for wireless LAN systems. It is derived
from and is forward compatible with the IEEE 802.11i standard. WPA
leverages Temporal Key Integrity Protocol (TKIP) and Michael message
integrity check (MIC) for data protection, and 802.1X for authenticated key
management.
WPA supports two mutually exclusive key management types: WPA and
WPA passphrase (also known as WPA-Pre Shared Key (PSK)). Using WPA,
clients and the authentication server authenticate to each other using an EAP
authentication method, and the client and server generate a pairwise master
key (PMK). The server generates the PMK dynamically and passes it to the
access point.
•

Chapter 5 Configuring network security
This option enables WPA passphrase security (also known as WPA-Pre
Shared Key (PSK)).
•
802.1x security
This option enables 802.1x security. This option requires network
administration support. This option includes the EAP (with dynamic WEP
keys) security protocols: EAP and PEAP.
802.1x is the standard for wireless LAN security defined by IEEE as 802.1x
for 802.11, or simply 802.1x.
An access point that supports 802.1x and its protocol, Extensible
Authentication Protocol (EAP), acts as the interface between a wireless client
and an authentication server, such as a RADIUS server, to which the access
point communicates over the wired network.
•
Pre-Shared Key security (static WEP)
This option enables the use of up to four pre-shared (static wired equivalent
privacy (WEP)) keys that are defined on both the access point and the station.
These keys are stored in an encrypted format in the registry of the Windows
device. When the driver loads and reads the client adapter’s registry
parameters, it also finds the static WEP keys, decrypts them, and stores them
in volatile memory on the adapter.
If a device receives a packet that is not encrypted with the matching key, the
device drops the packet and never delivers it to the intended receiver.
•
No security
Link encryption/decryption is disabled; no keys are installed.
Authentication sequence
Enabling EAP on the access point (AP) and configuring the client adapter for
EAP-TLS, EAP-TTLS, PEAP (EAP_GTC), or PEAP (EAP-MSCHAP V2)
authentication to the network occurs in the following sequence:
216669-A
The client associates to an AP and begins authentication.
Communicating through the AP, the client and the RADIUS server complete
authentication with the password (PEAP) or certificate (EAP-TLS/
EAP-TTLS). The password is never transmitted during the process.
Preliminary Draft - Nortel Networks Confidential
Chapter 5 Configuring network security
49
After successful authentication, the client and RADIUS server derive a
dynamic WEP key that is unique to the client.
The RADIUS server transmits the key to the AP using a secure channel on the
wired LAN.
For the length of the session, the AP and the client use this key to encrypt or
decrypt all unicast and broadcast packets.
EAP security
To use EAP security, access the Security tab in the Profile Management window
of the Mobile Adapter 2202 Utility and perform the following steps:
In the Profile Management window, click on New or Modify to edit the
security settings.
Select a profile to edit, or enter a name for the new profile in the Profile
Management window, and enter the SSID of the AP to which the station
connects.
On the Security tab, select the WPA radio button or the 802.1x radio button
depending on what type of EAP security you want to configure.
Select EAP-TLS or EAP-TTLS from either the WPA EAP Type or 802.1x
EAP Type drop-down menu as appropriate, depending on what you selected
in step 3.
Do one of the following:
•
•
To enable EAP-TLS security, go to “Enabling EAP-TLS security.”
To enable EAP-TTLS security, go to “Enabling EAP-TTLS security.”
Enabling EAP-TLS security

PEAP security
Two types of PEAP security are provided as follows:
•
PEAP (EAP-GTC) authentication is designed to support one-time password
(OTP), the Windows NT or Windows 2000 domain, and L DAP users
databases over a wireless LAN. It is based on EAP-TLS authentication but
uses a password instead of a client certificate for authentication. PEAP
(EAP-GTC) uses a dynamic session-based WEP key derived from the client
adapter and RADIUS server to encrypt data.
Networks that use an OTP user database require entering a hardware or
software token password to start the PEAP (EAP-GTC) authentication
process and to gain access to the network. Networks that use a Windows NT
or Windows 2000 domain user database or an L DAP user database (such as
NDS) require entering a username, password, and domain name in order to
start the PEAP (EAP-GTC) authentication process.
•
The PEAP (EAP-MSCHAP V2) authentication type is based on EAP-TLS
authentication, but uses a password instead of a client certificate for
authentication. PEAP (EAP-MSCHAP V2) uses a dynamic session-based
WEP key, which is derived from the client adapter and RADIUS server, to
encrypt data.
To use PEAP security, access the Security tab in the Profile Management window
of the Mobile Adapter 2202 Utility and perform the following steps:
In the Profile Management window, click on New or Modify to edit the
security settings.
Select a profile to edit, or enter a name for the new profile in the Profile
Management window, and enter the SSID of the AP to which the station
connects.
On the Security tab, select the WPA radio button or the 802.1x radio button
depending on what type of EAP security you want to configure.
Select PEAP (EAP-GTC) or PEAP (EAP-MSCHAP V2) from either the
WPA EAP Type or 802.1x EAP Type drop-down menu as appropriate,
depending on what you selected in step 3.
