vi Intel® PRO/Wireless 2011B LAN USB Device User’s Guide

Chapter 1. Introduction to wireless networking

The Intel® PRO/Wireless 2011B LAN USB Device is an 802.11b wir e less net w ork in g d evice that
connects to a USB port on your computer . Intel ® PRO/Wireless 2011B LAN netwo rk p rodu ct s are
based on the IEEE 802.11b standard and connect computers together to form a wireless local area
network (WLAN).

All Intel® PRO/Wireless 2011B LAN products interoperate with other IEEE 802.11b compliant
wireless devices from other vendors. The WiFi certification logo indicates that the wireless device
is 802.11b compliant.

The Intel® PRO/Wireless 2011B LAN USB Device operates in either infrastructure mode or peer­to-peer mode.

1.1 Infrastructure Mode: A WLAN with Access P o ints

In infrastructure mode, wireless clients send and recei ve info rmation through access po ints. 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.

Intel® PRO/Wireless 2011B LAN USB Device Users Guide 1

Chapter 1. Introduction to wireless networking

1.3 Identifying a WLAN

All the devices on a WLAN use a Network Name, or Service Set Identifier (SSID) to identify the
WLAN. 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.
This guide uses SSID as a general term for both ESSID and IBSSID. All the devices on a WLAN
must use the same SSID to communicate with other wireless devices. When installing an access
point or wireless device 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 device installed in the wireless
client. The MAC address is permanently set when the device 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

T o vie w the MA C address o f an Intel® PRO/Wireless 2011B LAN USB device, see the label on the
back 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 sp ecif ies the Wired Equi v alent Pri vacy (WEP) encryptio n
and decryption algorithm. The standard includes two levels of security, using a 40-bit key or a 128­bit 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 ti mes as many po ssi ble 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.

2Intel® PRO/Wireless 2011B LAN USB Device Users Guide

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 rang e throug hou t most of the w orld . The actual
range is country-depen dent.

1.7 Intel® PRO/Wireless LAN USB Software

Intel® PRO/Wireless LAN USB software consists of the Windows device drivers for the USB
Device and the Wireless LAN Configuration Utility. The configuration utility allows you to
evaluate de vice perf ormance and display and modify the wireless LAN settings for the Intel® PR O/
Wireless 2011B LAN USB Device. Settings include the operating mode, the SSID, transmission
rate, and encryption keys used for wireless network communication.

For the network device to function in a wireless LAN, you must change the settings to match the
settings of ot her wireles s devices in your ne twork.
