Intel® PRO/Wireless 2011B LAN Adapter Product Reference Guide 1
Chapter 1. Introduction to wireless networking
The Intel® PRO/Wireless 2011B LAN Adapter is an Intel® PRO/Wireless 2011B LAN network
product. Intel® PRO/Wireless 2011B LAN network products are based on the IEEE 802.11b
standard and connect computers together to form a wireless network.
A Local Area Network (LAN) is a network in a central location. Users at that location share files,
printers, and other services. In a LAN, a networked computers that request services are called
clients, while servers in a LAN provide services. In a wireless LAN (WLAN), wireless adapters are
installed in clients. A wireless client communicates with the WLAN without cables. Instead,
wireless clients send and receive information through the air.
All Intel 802.11b compliant devices interoperate with other 802.11b compliant wireless devices
from other vendors. The WiFi certification logo indicatesthat the wireless device has been tested by
an independent organization and is 802.11b compliant.
A wireless client operates in either infrastructure mode or peer-to-peer mode.
1.1 Infrastructure Mode: A WLAN with Access Points
In infrastructure mode, wireless clients send and receive information through access points. When a
wireless client communicates with another, it transmits to the access point. The access point
receives the information and rebroadcasts it. Then the other device receives the information.
Access points are strategically located within an area to provide optimal coverage for wireless
clients. A large WLAN uses multiple access points to provide coverage over a wide area. Access
points can connect to a LAN through a wired Ethernet connection. Access points send and receive
information from the LAN through this wired connection.
1.2 Peer-to-Peer Mode: A WLAN without Access Points
In peer-to-peer mode, also called Ad Hoc Mode, wireless clients send and receive information to
other wireless clients without using an access point. In contrast to infrastructure mode, this type of
WLAN only contains wireless clients.
You can use peer-to-peer mode to network computers in a home or small office, or to set up a
temporary wireless network for a meeting.

Chapter 1. Introduction to wireless networking
2 Intel® PRO/Wireless 2011B LAN Adapter Product Reference Guide
1.3 Identifying a WLAN
All the devices on a WLAN use a Network Name, or Service Set Identifier (SSID) to identify the
WLAN. There are several kinds of SSIDs, each having a slightly different meaning. In peer-to-peer
mode, an Independent Basic Service Set Identifier (IBSSID) identifies a WLAN. In infrastructure
mode, an Extended Service Set Identifier (ESSID) identifies a WLAN. For simplicity, this guide
uses the term Network Name (SSID) in place of ESSID and IBSSID. Regardless of whether you are
dealing with a infrastructure of peer-to-peer WLAN, the SSID indicates what WLAN you are
communicating with. All the devices on a WLAN must use the same SSID to communicate with
other wireless devices. When installing an access point or wireless adapter in a wireless client, the
software asks you to specify an SSID.
1.4 Identifying Devices on a WLAN
A Basic Service Set Identifier (BSSID) uniquely defines each wireless device. The BSSID is the
Ethernet Media Access Control (MAC) address of the wireless adapter installed in the wireless
client. The MAC address is permanently set when the adapter is manufactured. MAC addresses
determine the device sending or receiving data. A MAC address is a 48-bit number written as six
hexadecimal bytes separated by colons. For example:
00:A0:F8:24:9A:C8
To view the MAC address of an Intel® PRO/Wireless 2011B LAN device, see the bottom of the
device.
1.5 Wireless Security
Wireless networking devices transmit information through the air. Without implementing security,
it is easy for an unauthorized person to intercept the information.
A common way of implementing security and protecting information is encryption. Before sending
information, the wireless client or access point encrypts or scrambles information using an
encryption key. The device receiving the information uses the same key to decrypt or unscramble
the information. The information is only readable to wireless devices that have the correct
encryption key.
The IEEE 802.11 wireless LAN standard specifies the Wired Equivalent Privacy (WEP) encryption
and decryption algorithm. The standard includes two levels of security, using a 40-bit key or a 128-
bit key. To implement WEP, use either one of these methods. For better security, use a 128-bit key.
A 128-bit key has several trillion times as many possible combinations as a 40-bit key. For added
security, change your keys often. Some vendors refer to 40-bit encryption as 64-bit. These are
identical. A wireless device that claims to have 40-bit encryption interoperates with a device that
claims to have 64-bit encryption.
The same device, host computer or front-end processor usually performs both encryption and
decryption. The algorithm, like the pattern of a lock, is standardized and may be used by anyone,
but the encrypted data is unreadable without the appropriate key, which is known only by the sender
and receiver of the transmitted data. You should change your keys often for added security.
1.6 Radio Basics
IEEE 802.11 networking devices transmit and receive radio signals. Users communicate with the
network by establishing radio links between mobile devices and access points, or between each
other.

Intel® PRO/Wireless 2011B LAN Adapter Product Reference Guide 3
IEEE 802.11 devices use frequency modulation (FM) to transmit digital data from one device to
another. The radio signal propagates into the air as electromagnetic waves. The receiving device
demodulates the signal, which results in the original digital data. The radio devices transmit in the
2.4 to 2.5 gigahertz frequency range, a license-free range throughout most of the world. The actual
range is country-dependent.

Chapter 2. About the Intel® PRO/Wireless 2011B LAN Adapter
The Intel® PRO/Wireless 2011B LAN Adapter is an Intel® PRO/Wireless 2011B LAN network
product. Intel® PRO/Wireless 2011B LAN network products operate between 2.4 and 2.5 gigahertz
(GHz) using direct-sequence spread spectrum (DSSS) technology.
Adapter features include:
• IEEE 802.11b specification compatibility. This open architecture allows Intel® PRO/Wireless
2011B LAN devices to communicate with wireless devices from other vendors.
• 11 Mbps data rate for high-capacity, fast operation
• Standard Network Driver Interface Specification (NDIS).
• Microsoft Windows† 95, Windows 98, Windows 2000 and Windows CE† driver support.
• Card and Socket Services support.
• WEP data security
• Plug and Play support.
• operating range of about 45 meters (150 feet).
• Low-power operation for battery-powered devices with PC Card slots. Power management
includes Continuously Aware Mode (CAM)andPower Save Polling (PSP).
• peer-to-peer mode for connecting directly to other computers
• station mode for use with single or multiple access points
• roaming support for mobile LAN connections throughout large facilities
The adapter can only be installed in a PC Card slot in a suitably equipped computer. The adapter
contains a built-in radio antenna that protrudes when inserted into the slot.
The Intel® PRO/Wireless 2011B LAN Adapter allows Personal Computer Memory Card
International Association (PCMCIA) 3.3-volt Type II PC Card slot-equipped computers to
configure, connect to and establish an Intel® PRO/Wireless 2011B LAN network.
Unlike the Intel® PRO/Wireless 2011 LAN Adapter, which is a 5-volt Type II PC Card with a PCI
carrier for use with a non-mobile computers, the Intel® PRO/Wireless 2011B LAN Adapter is a
3.3-volt Type II PC Card that you can use only mobile computers. You cannot use this PC Card
with a PCI carrier.
The exposed end of the adapter is vulnerable to damage from scratching, snagging or striking other
objects. Such contact may bend or break the adapter or the PC Card slot in which it resides.
2.1 Intel® PRO/Wireless 2011B LAN Adapter Operating Modes
The Intel® PRO/Wireless 2011B LAN Adapter supports the following operational modes:
• ESS (802.11 Station) infrastructure mode: The adapter connects to an access point. In ESS
mode, the adapter can roam freely between access point cells in the network or transmit and
receive across subnets.
• IBSS (802.11 Ad Hoc) peer-to-peer mode: Use this mode to form peer-to-peer networks

Chapter 2. About the Intel® PRO/Wireless 2011B LAN Adapter
Intel® PRO/Wireless 2011B LAN Adapter Product Reference Guide 5
without access points. The wireless computer starting the IBSS network (the first adapter
transmitting a beacon) determines the channel used for the computers in the IBSS network.
• Pseudo IBSS (Proprietary Ad Hoc) mode: Use this mode when the highest throughput is
required in an IBSS network to test performance. In Pseudo IBSS mode, each adapter is
required to be on the same channel. Pseudo IBSS is not recommended for devices operating on
battery power.
2.2 11 Mbps Operation
The Intel® PRO/Wireless 2011B LAN Adapter supports a maximum 11 Mbps data rate. The
adapter automatically changes to a 5.5, 2, or 1 Mbps data rate when unable to maintain a high
quality connection at 11 Mbps.
The following factors can dynamically alter the data rate:
• signal strength between the access point and the computer.
• the ratio of good transmitted packets to attempted transmitted packets falls below a threshold.
• the computer encounters an unspecified data rate or finds a higher transmit rate with another
access point.
2.3 Mobile IP
The Intel® PRO/Wireless 2011B LAN Adapter supports Mobile IP. The Mobile IP feature allows
Intel® PRO/Wireless 2011B LAN devices to roam across routers.
The computer retains its IP address when configured for Mobile IP and can:
• move from one IP subnet to another.
• move from an Ethernet segment to a wireless LAN.
• move from one Ethernet segment to another.
When the client moves to an access point on another subnet, mobile IP allows it to continue to
communicate as if it were on it’s original subnet. Mobile IP uses a packet tunneling technique to
deliver data to the proper subnet. This additional overhead may result in slightly lower data
throughput than that seen on the “home” subnet.
2.4 Power Management
The WLAN adapter supports the Continuously Aware Mode (CAM) and Power Save Polling (PSP)
power-management modes. CAM requires the radio to remain on. Intel does not recommend CAM
for battery powered devices.

Chapter 2. About the Intel® PRO/Wireless 2011B LAN Adapter
6 Intel® PRO/Wireless 2011B LAN Adapter Product Reference Guide
PSP mode allows the computer to conserve power by suspending communication for short periods
of time while still associated with an access point. The access point saves data for transmission to
the computer when it wakes at given intervals.
The PSP performance index, which varies from 1 to 5, allows you to specify how often the
computer wakes up to check for data. PSP performance index 1 provides the quickest response time
(shortest sleep interval), while PSP performance index 5 provides efficient power consumption
(longest sleep interval).
2.5 Card and Socket Services
The Intel® PRO/Wireless 2011B LAN Adapter supports Card and Socket services. Card and
Socket Service software packages work with the host computer operating system enabling the
WLAN adapter to interface with host computer configuration and power management functions.
Card and Socket Service software packages include SystemSoft and Phoenix.
2.6 Plug and Play
The Intel® PRO/Wireless 2011B LAN Adapter supports Plug and Play systems. This allows a
computer to recognize the adapter, and to configure the hardware interrupt, memory and device
recognition addresses. This feature simplifies installation and minimizes hardware conflicts.
2.6.1 Data Encryption
The Intel® PRO/Wireless 2011B LAN Adapter uses the Wired Equivalent Privacy (WEP)
encryption and decryption algorithm specified in Section 8 of the IEEE 802.11 wireless LAN
standard. WEP uses the same key for both encryption and decryption, and provides security
equivalent to that of a wired network, hence the “Wired Equivalent” portion of the name.
The IEEE 802.11 standard defines two types of authentication:
•Open system authentication is the default authentication service, in which all clients that
request access to the network are accepted, with no actual verification. You should only use
this system if it’s not necessary to positively validate the identity of the sender.
•Shared key authentication requires the exchange of an authentication key shared among all
of the authentic access points and clients in the network. When a client requests access to the
network, the access point sends a long random number encrypted with the shared key to the
client. The client decrypts the number using the same key and sends it back to the access point,
which only grants access to clients that return the correct number. The Intel® PRO/Wireless
2011B LAN Access Point supports both 40-bit and 128-bit shared key encryption.
If you implement the shared key authentication mode, you must configure all access points and
clients to use the same key.
To implement WEP on each access point, use either a 40-bit key or a 128-bit key. A 40-bit key
consists of 10 hexadecimal numbers in two 5-digit groups, arrayed as follows.
10111 21314
A 128-bit key consists of 26 hexadecimal numbers in two 5-digit groups and four 4-digit groups,
arrayed as follows.
