1.About Wireless LAN Technology
A wireless network connects computers without using network cables. Computers use radio
communications to send data between each other. You can communicate directly with other
wireless computers, or connect to an existing network through a wireless access point. When
you set up your wireless adapter, you select the operating mode for the kind of wireless network
you want. You can use your Intel(R) PRO/Wireless adapter to connect to other similar wireless
devices that comply with the 802.11 standard for wireless networking.
Choosing a Wireless LAN Mode
Wireless LANs can operate with or without access points, depending on the number of users in
the network. Infrastructure mode uses access points to allow wireless computers to send and
receive information. Wireless computers transmit to the access point, the access point receives
the information and rebroadcasts it to other computers. The access point can also connect to a
wired network or to the Internet. Multiple access points can work together to provide coverage
over a wide area.
Peer-to-Peer mode, also called Ad Hoc mode, works without access points and allows wireless
computers to send information directly to other wireless computers. 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.
Configuring a Wireless LAN
There are three basic components that must be configured for a wireless LAN to operate
properly:
•
Network Name—Each wireless network uses a unique Network Name to identify the
network. This name is called the Service Set Identifier (SSID). When you set up your
wireless adapter, you specify the SSID. If you want to connect to an existing network,
you must use the name for that network. If you are setting up your own network you can
make up your own name and use it on each computer. The name can be up to 32
characters long and contain letters and numbers.
•
Profiles—When you set up your computer to access a wireless network, Intel(R)
PROSet creates a profile for the wireless settings that you specify. If you want to
connect to another network, you can scan for existing networks and make a temporary
connection, or create a new profile for that network. After you create profiles, your
computer will automatically connect when you change locations.
•
Security—The 802.11 wireless networks use encryption to help protect your data.
Wired equivalent privacy (WEP) uses a 64-bit or 128-bit shared encryption key to
scramble data. Before a computer transmits data, it scrambles the data using the secret
encryption key. The receiving computer uses this same key to unscramble the data. If
you are connecting to an existing network, use the encryption key provided by the
administrator of the wireless network. If you are setting up your own network you can
make up your own key and use it on each computer.
Identifying a Wireless Network
Depending on the size and components of a wireless LAN, there are many ways to identify a
wireless LAN:
•
The Network Name or Service Set Identifier (SSID)—Identifies a wireless network. All
wireless devices on the network must use the same SSID.
•
Extended Service Set Identifier (ESSID)—A special case of SSID used to identify a
wireless network that includes access points.
•
Independent Basic Service Set Identifier (IBSSID)—A special case of SSID used to
identify a network of wireless computers configured to communicate directly with one
another without using an access point.
•
Basic Service Set Identifier (BSSID)—A unique identifier for each wireless device.
The BSSID is the Ethernet MAC address of the device.
•
Broadcast SSID—An access point can respond to computers sending probe packets
with the broadcast SSID. If this feature is enabled on the access point, any wireless
user can associate with the access point by using a blank (null) SSID.
Surveying the Site of Your Wireless LAN
Conducting a site survey for your wireless LAN is the most crucial step in the process of setting
up a wireless network. It greatly reduces the amount of troubleshooting you will have to do once
you have the wireless LAN set up and ready for connection testing. To conduct a site survey,
you will need the following tools:
•
An access point (or laptop computer) that is set up to be the transmitter. It should be
mounted near and at the same height as the designated location of your wireless LAN.
•
A laptop that will act as the mobile receiver. It must contain your site survey software.
•
An area or building map, which will be used to plot the strength of your signals.
Once you have the tools you need, you are ready to survey the inside of the building. Launch
the site survey software on the mobile receiver laptop and carry it around in the intended
wireless LAN area to test the signal strength. Be sure to also check the signal strength of each
intended access point location. If you encounter problems while surveying the site, make sure
your transmitter laptop is not located on a wall containing metal, such as an air-conditioning
duct, which will interfere with the range of your signal. Simply move the transmitter and test the
signal strength again. For users to have seamless coverage when moving from access point to
access point, the signal levels at each point must overlap. There is software available that will
seamlessly hand off changing signal levels from one access point to another.
Your building's infrastructure can sometimes interfere with the microwave signal, but finding the
location and cause of the interference will allow you to figure out the best place to mount your
access points for optimal area coverage. Microwave signals travel in all directions, which means
there is one access point for a multi-floor building. However, the range is highly dependent on
the material used to construct the flooring, especially metal materials. Once your signal strength
is strong inside the building, you are ready to check the strength outside the building. To do so,
simply carry the mobile receiver laptop as far down the street or around the building as you can
go without losing significant signal strength.
If possible, you should be aware of the types of networks being used by the companies on the
floors above and below you, so that you can work together in harmony. With wireless networks,
security is very important and if you communicate with those around you, you are better
prepared to select the right channels, as well as the best location for access points.
Factors Affecting Range
Although access points can transmit signals up to 60 feet away in an area with many walled
barriers or as much as 500 feet away in a large open area, the range is affected by the
following factors:
•
Building materials, such as steel and drywall, can shorten the range of the radio signals.
•
Physical layout of the area can interfere with the signals and cause them to be dropped.
•
Electronic noise from cell phones, microwave ovens, or other devices on the same
frequency can interfere with the transmission of the signals.
•
Range is inversely proportional to data rate, so the faster that the signals are sent, the
less distance they will travel.
Taking these factors into consideration when you survey the site for your WLAN is key to
providing all of your users with undisturbed mobile connectivity. Using multiple access points will,
of course, reduce the impact of these factors if your area has dividing walls throughout.
Stronger Security
Although wireless networks are easy to use, the main issue lies with security. Even if you
enable the security settings defined in the 802.11b standard, as well as the security settings of
your hardware, your network is still vulnerable. There are a few things you can do to make it
more difficult for outsiders to access your network:
•
Change the default network name of your WLAN. Every manufacturer's default settings
are public knowledge.
•
Do not allow the name of your network to be broadcasted by your access points. This
makes it more difficult for hackers to identify your network.
•
Enable Wired Equivalent Privacy (WEP) encryption, which is the same security feature
used by online shopping websites.
•
Change your encryption keys as often as possible. Temporal Key Integrity Protocol
(TKIP), which is being developed by a IEEE task group, will change the keys
automatically.
•
Enable MAC address filtering so that each access point can generate a list of approved
MAC addresses for your WLAN.
•
If you have a small network, use virtual private network encryption for additional security.
If you have a large network, you may want to install a gateway between your access
points and network clients.

13. After creating the new profile, click the profile in the Profile List. Profiles using
infrastructure mode are indicated by a computer icon next to the profile name.
14. Click the Connect button to connect to the ad hoc network.
Starting an Ad Hoc (peer-to-peer) Connection
To communicate properly, all computers/peers on an ad hoc network must have Intel wireless
adapters installed. To connect to an ad hoc network for a one-time session:
1. From the General page, select the wireless adapter on the left side pane.
2. Click the Networks tab.
3. Click the Start button.
4. Enter the password (SSID) for your computer in the text box. If you establish the ad hoc
network, then this SSID and assigned transmit channel must be used by other users to
connect to the ad hoc network. The entered SSID can also be the same as the other
users in the established ad hoc network, in this case your computer will join the ad hoc
network.
5. To join the ad hoc network, select the peer name from the displayed list of computers in
the ad hoc network and click the Connect button
6. To establish an ad hoc network, after your computer's SSID is entered, click the
Connect button to scan for other users in the ad hoc network

When the radio is on, an attempt will be made to associate with the network access point using
the last profile. If the adapter cannot connect to the access point, the Configuration Service will
attempt to find an available network. Refer to Configuration Service for more information.
Switching the radio on or off from the Task Tray Icon
Right-click on the Intel(R) PROSet task tray icon and click Switch radio Off.
Using the Windows operating system to switch the radio on/off
The radio can be switched on or off via the Windows operating system from the Device
Properties dialog.
Switching Between Wired and Wireless Adapters
Adapter switching enables your computer to automatically switch between wired and the
wireless adapter, so your laptop computer can maintain the best possible connection to the
network while moving from one location to another. When Adapter Switching is enabled, DHCP
is disabled on all other wired adapters except for the adapter currently being used. However,
connection is possible using another wired adapter using an auto IP address setting.
Adapter switching switches between wired and wireless adapters for the following Intel PRO
adapters:
•
Wired LAN adapters. This type of adapter connects to a network through an Ethernet
network cable. Adapter Switching supports adapters in the PRO/100 family, including
the PRO/100 Mobile Adapters.
•
Intel PRO/Wireless LAN 7100 3B Mini PCI adapter and the Intel PRO/Wireless LAN
2100 3B Mini PCI adapter. These adapter send data to and from the network through
the adapter's antenna.
By default, adapter switching uses the wired Ethernet adapter when both wired and wireless
adapters are present and working. If you detach the wired adapter, adapter switching
automatically switches to the wireless adapter. When you attach an Ethernet cable again,
adapter switching automatically switches back to the wired Ethernet connection.
You can change your wireless preferences from the Advanced Settings dialog and prioritize
your wireless and wired adapters from the Adapter Switching dialog.
You can also install multiple wired adapters, or install two wireless adapters if the network
supports both 802.11a and 802.11b wireless standards. Then when you detach the wired
adapter, your computer uses the wireless adapter that gives the best data rate.
Wireless Preferences
One or more wired adapter and one or two wireless adapter can be installed in the same
computer. Using the adapter switching feature, you can select your priority for a specific type of
adapter, wired or wireless.
If adapter switching is enabled, the installed adapters are selected from a preference list. To
access the network preferences:
1. From the General page, select the wireless adapter on the left side pane.
2. Click the Networks tab.
3. Click the Advanced button.
4. Select your preferences from the options shown.
5. Click OK to save the settings and return to the Profiles dialog.
Adapter Switching Considerations
Consider the following issues when switching adapters:
•
Adapter switching requires the use of DHCP. It cannot be used with fixed IP addressing.
•
Only Intel wired and wireless adapters are supported when using the Start button to
connect to an ad hoc network.
•
Adapter switching cannot be used on a Virtual Private Network (VPN).
•
Adapter switching should not be applied while an active data transfer is in progress.
•
Intel(R) PROSet determines how many wireless adapters are present in the computer.
•
Intel(R) PROSet supports simultaneous wireless adapter operation for the following:
2.4 GHz and 5 GHz installed adapters: Supports simultaneous operation in
either ad hoc or infrastructure mode.
2.4 GHz and 2.4 GHz installed adapters: Supports simultaneous operation
where one adapter is in ad hoc mode and the other adapter is in infrastructure
mode. Simultaneous operation with both adapters in infrastructure or ad hoc
mode is not be supported.
The second adapter added is not supported.
5 GHz and 5 GHz installed adapters: Supports simultaneous operation where
one adapter is in ad hoc mode and the other adapter is in infrastructure mode.
Simultaneous operation with both adapters in infrastructure mode or ad hoc is
not supported.
The second adapter added is not supported.
o
Maximum of four adapters is supported.
Switching Between 2.4 and 5 GHz Bands
Intel(R) PROSet supports switching between 802.11a (5 GHz) and 802.11b (2.4 GHz) bands.
Using the Advanced Settings options, you can define band priorities.
Changing the Settings for Adapter Switching
If you have two adapters installed, you can define the adapter to be used first. Adapter priorities
can be set in the Adapter Switching dialog.
To change the adapter switching settings:
1. From the General page, select the wireless adapter on the left side pane.
2. Click the Adapter Switching icon on the left side pane.
3. Click the Adapter Switching checkbox under the Settings heading.
4. Prioritize adapters in the lower adapter display list.
Select an adapter in the Adapter Type list and use the up/down arrows on the left side
of the dialog to arrange the adapters in priority. The adapter in the highest position is
used first.
5. Click the adapter name that you want to use in the upper display list. The current
adapter link status displays next to the adapter name.
NOTE: One wireless adapter can be used for each band operating at a time.
6. After you have switched to the desired adapter, click OK to close the Adapter Switching
dialog and return to the General tab.
5.Security Overview
Wireless Security
Since wireless networking devices transmit information through radio waves, it is imperative that
you protect your information by configuring your security settings. There are three main
components that, when used together, can protect your wireless network:
•
Service Set Identifier (SSID) — The name of a device on a network, the SSID is the first
level of security, but it is not fool-proof because the access points broadcast the SSIDs
across a wireless network. This level of security is okay if you are on a peer-to-peer
network without any access points, but for larger networks, more complex security
measures should be put in place.
•
Wired Equivalent Privacy (WEP) — Supported by the IEEE 802.11 standard, WEP uses
64- or 128-bit encryption keys to encrypt data as it is sent or received by each client on
a wireless network. The way these keys are authenticated determines the level of
security on your wireless network. Using the default keys, however, makes your
wireless network vulnerable and you should not use them.
•
Authentication Server — An authentication server works with each client to authenticate
access with a session-specific WEP key. This type of server protects sensitive user and
password information from intruders.
Security Guidelines
The following can help to achieve maximum security for your wireless network:
1. Enable WEP on your wireless network and change the WEP key daily or weekly.
2. Protect your drives and folders with passwords.
3. Change the default SSID.
4. Change the WEP key with each session, if possible.
5. Enable MAC address filtering, if possible.
6. Implement a Virtual Private Network (VPN) system to increase security. A VPN client is
included in most operating systems.
Protecting Your Network
Authentication Types
The IEEE 802.1x standard provides a general authentication framework for 802 LANs and
specifies an extensible authentication protocol (EAP) to enable LAN transport for many different
types of authentication protocols.
Encryption Keys
To protect client traffic, the 802.11 standard defines Wireless Encryption Privacy (WEP) with
fixed encryption keys (and three optional key lengths). The use of fixed keys has made it easy
to mount several types of attack against WEP.
WEP Encryption
You can prevent unauthorized reception of your wireless data using the IEEE 802.11 Wired
Equivalent Privacy (WEP). The standard includes two levels of security, using a 64-bit key
(sometimes referred to as 40-bit) or a 128-bit key. For better security, use a 128-bit key. If you
use encryption, all wireless devices on your WLAN must use the same encryption settings.
Refer to Setting up WEP Encryption for more information.
802.1x
A WAN client initiates an authorization request to the access point, which authenticates the
client to an Extensible Authentication Protocol (EAP) compliant RADIUS server. This RADIUS
server may authenticate either the user (via passwords) or the machine (by MAC address).
IPSEC
Software based IPSEC transport security.
TKIP (Temporal key Integrity Protocol)
Uses an encryption method called fast-packet rekeying, that changes the encryption keys
frequency.
Virtual Private Networks (VPN)
The following VPN client software is supported by PROSet. Refer to Virtual Private Network
(VPN) for more information.
•
Netstructure VPN (SST)
•
Netstructure VPN (IPsec-IKE)
•
Cisco 3000 VPN
•
Checkpoint VPN (Non office transparent mode, connect office mode and connect nonoffice mode)
•
Microsoftt VPN (L2TP over IPsec transport, L2TP for configuration with ESP-in-UDP)
802.11a and 802.11b can be augmented with VPN security to protect TCP/IP based services.
6.Setting Up WEP Encryption and Authentication
Wired Equivalent Privacy (WEP) encryption and shared authentication provides protect for your
data on the network. WEP uses an encryption key to encrypt data before transmitting it. Only
computers using the same encryption key can access the network or decrypt the encrypted data
transmitted by other computers. Authentication provides an additional validation process from
the adapter to the access point.
Supported authentication schemes are Open and Shared-Key authentication:
•
Shared-Key authentication is supported using 64-bit and 128-bit WEP encryption keys.
•
Open mode does not use an encryption authentication method to associate to a specific
access point.
Encryption Overview
Security in the WLAN can be achieved by enabling data encryption using WEP (Wireless
Encryption Protocol). You can choose a 64 or 128 bit level encryption. Also, the data can then
be encrypted with a key. Another parameter called the key index is provides the option to create
multiple keys for that profile. However, only one key can be used at a time. You can also
choose to password protect the profile to ensure privacy.
The pass phrase is used to generate a WEP key automatically. You have the option of either
using a pass phrase or entering a WEP key manually. Using 64-bit encryption, the pass phrase
is 5 characters long and you can choose to enter any arbitrary and easy to remember phrase
like Acme1 or enter 10 Hexadecimal numbers for the WEP key corresponding to the network
the user wants to connect to. For 128-bit encryption, the pass phrase is 13 characters long or
you can enter a 26 hexadecimal numbers for the WEP key to get connected to the appropriate
network.
Note: You must use the same encryption type, key index number, and WEP key as other
devices on your wireless network. Also, if 802.1x authentication is being used, WEP encryption
must be disabled.
To enable 64-bit (40-bit) or 128-bit encryption with authentication:
1. Select the wireless adapter in the left-side pane.
2. From the General page, click the Networks tab.
3. Select the profile from the Profile List and click the Edit button or click the Add button if
you are using the Profile Wizard.
4. Click the Security tab. Select Security Settings, the third dialog if using the Profile
Wizard.
5. Select Shared from the Network Authentication drop-down box.
6. Select 64-bit or 128-bit from the Encryption Level drop-down box.
7. Select a key index number 1, 2, 3, or 4 from the Encrypt data with key index drop-down
box to use for encryption. Key selection corresponds to the WEP encryption pass
phrase or WEP key.
8. Select either of the following:
•
Pass phrase: Click Use Pass Phrase to enable it. Enter a text phrase,
up to five (using 64-bit) or 13 (using 128-bit) alphanumeric characters
(0-9, a-z or A-Z), in the pass phrase field.
•
WEP key: Click Use WEP Keys to enable it. Enter up to ten (using
64-bit) alphanumeric characters, 0-9, A-F, or twenty-six (using 128bit) alphanumeric characters, 0-9, A-F in the WEP key field.
9. Click OK if editing a profile or Finish if in the Profile Wizard to save the settings.
NOTE: You must use the same encryption type, index number, and WEP key as other
devices on your wireless network.
7.Troubleshooting
Using a Profile with an incorrect WEP Encryption Key
When connected to an access point using a profile with an incorrect WEP key encryption, the
task tray icon and the General page will both indicate good signal strength and that you are
associated with the AP. However, when you attempt to send data to the AP using this profile,
because of the incorrect WEP key encryption, authentication cannot be established to acquire
an IP address from the AP to allow data transfer.
Refer to the following WEP encryption and authentication settings.
Open Authentication with an incorrect WEP 64 or 128-bit encryption key:
•
A profile with an incorrect WEP encryption key will allow the wireless adapter to
associate with the access point.
•
No data transfer
Open Authentication with no WEP encryption:
•
Allows association to an access point
•
Data transfer is allowed
Shared Authentication:
•
Associated to an AP always allows data transfer.
Problems with installation
Windows does not detect the wireless adapter:
1. Remove and re-install the adapter.
2. Uninstall and reinstall the adapter's drivers.
Before calling Customer Support
Make a note of the following answers before calling customer support:
•
How many remote units do you have talking to each access point?
•
What channels are you using, and how are they dispersed?
•
How much coverage overlap is there between access points?
•
How high above the floor are the access points mounted?
•
What revision of Intel(R) PROSet software or other LAN software are you running?
•
What other electronic equipment is operating in the same band?
•
What construction materials are used in wall and floors?
Users are dropped from the wireless network
Suggested causes and solutions:
•
Find out if a person or workgroup moved or if the building has been rearranged.
•
If two or more users are seated too close to each other, performance can suffer. Instruct
your users to space themselves a small distance apart to keep receivers from being
overloaded.
•
Delivery trucks with very large metal sides can affect performance by reflecting
destructive signals back into a building. If you have an installation that includes a
shipping dock, check to see if the problem coincides with the arrival of large trucks.
•
Personal “systems” can also interfere with your network. Wireless speakers, cordless
earphones, some Bluetooth devices, and similar systems can be the source of an
infrequent but hard to find the problem. Some systems do not conform to wireless
regulations. Shut off suspect devices or remove them from the area.
•
If possible, remove and reinstall your new software. Conflicts with other resident
software packages are always a possibility, and they are not always the fault of the
newest addition. Sometimes just starting over fixes the problem.
•
Swap units around. Does your problem follow the changed units, or is it unique to a
specific location? If it follows the product, the swapped unit could be damaged, or
improperly configured. If the problem stays with the location, try to find out what is
different about that particular room or area.
Range decreases as data rate increases
This is a normal condition. Range is inversely proportional to data rate: the faster the data, the
shorter the range. This has to do with the modulation technology used. Very fast data rates
require extremely complex signal waveforms, where even minor distortions can result in data
errors. Slower data rates are much more tolerant, and consequently will get through even in the
presence of some amount of noise, interference, distortion and echo.
Signal doesn't pass through a short or thin wall
Range is highly dependent on the physical environment. In a line-of-sight location, with elevated
and calibrated antennas, range predictions are quite accurate. This is not true in a “typical”
office building, where the walls may be simple drywall (which is almost transparent to
microwaves), or could be plaster with metal underneath. Most sites are somewhere between
these two extremes, and consist of a mixture of surfaces. You can’t tell what is inside a wall by
just looking at it, and we can’t tell you exactly what distance you will achieve. Consider
published range information to be typical, average, common or usual. Do not expect it to be
exact.
Signal strength drops when a cell phone is used in the area
Range also depends on the electronic environment. If other equipment that could cause
interference is nearby, the range of your transceiver could vary widely, and could change
suddenly when the other equipment activates. This is particularly true for 802.11b installations,
which share their frequencies with microwave ovens, cordless phones, wireless hi-fi speakers,
electronics toys and similar devices. Try to keep your system away from other transmitters, and
from other sources of electrical noise, such as large motors, spot welders, and similar
“electronically noisy” devices.
Range is shorter than it should be
Repeat some tests late in the evening, or on a weekend, when there may be less interference.
However, some users leave their networks turned all the time so this test is not foolproof. By all
means, try more than one channel. Your range problem may just be a nearby user whose
system uses your present test channel.
Interference from fluorescent lights
If you mount an access point close to fluorescent light fixtures, the lamp glow appears constant,
but inside the lamp tube, ionization appears and disappears 120 times a second. This can
modulate or “chop” an incoming signal and interfere with reception.
When too much range is undesirable
Too much range is not necessarily a good thing. At first it would appear that you would want as
much range as possible, but with the increase in range comes an increase in interference
potential, as your unit hears not only your other units but also manages to hear the systems of
other companies up and down the street. If you have a large installation, you will also wind up
with more than one access point using the same channel. If a remote unit hears two or more
access points, this will slow the network
Prevent access to wireless networks from outside the building
Excess transmit range presents a special reverse problem. For example, putting an access
point adjacent to a second floor bay window invites anyone with the right software on the street
below to pick up and enjoy all network transmissions. We discuss some possible solutions to
this problem further on.
Problems with Network Connectivity
If you cannot connect to the wireless network, try the following:
Check Network Settings
1. Select the wireless adapter in the Intel(R) PROSet left side pane.

9.Glossary
Numerical
802.11 x: A series of IEEE specifications for LANs: currently 802.11b, 802.11a, and 802.11g.
Using any one of these extensions to the 802.11 standard permits wireless communication
between a client and an access point or between two clients. The various specifications govern
transmission speeds and radio frequencies as well as fall-back rates and other characteristics.
The upcoming standard 802.11i will provide additional security specific to WLANs, and 802.11e
will address quality of service.
Access Point: A device that serves as a communications hub for wireless clients and provides
a connection to a wired LAN.
Advanced Encryption Standard (AES): A federal information-processing standard, supporting
128-, 192-, and 256-bit keys.
Basic Service Set Identifier (BSSID): A unique identifier for each wireless client on a wireless
network. The BSSID is the Ethernet MAC address of each adapter on the network.
Bit Rate: The total number of bits (ones and zeros) per second that a network connection can
support. Note that this bit rate will vary, under software control, with different signal path
conditions.
Bluetooth: An incompatible, very short-range lower speed communications system (PAN),
developed first in Europe as a “cable replacement” for printers and similar peripheral
connections. Its usage has expanded to include cordless earphones and similar devices. It uses
the 2.4 GHz ISM band, and “co-exists” with 802.11b. Here the term, “co-exist” means that not all
researchers agree on the amount of mutual interference generated when both systems operate
in the same location.
Broadcast SSID: Used to allow an access point to respond to clients on a wireless network by
sending probes.
Data Rate (Information Rate): Not all bits carry user information. Each group (packet) of bits
contains headers, trailers, echo control, destination information, and other data required by the
transmission protocol. It is important to understand the difference between bit rate and data rate,
since the overhead information may consume more than 40% of the total transmission. This
difference is common to many such data systems, including Ethernet.
Direct-Sequence Spread Spectrum (DSSS) and Frequency-Hop Spread Spectrum (FHSS):
Two incompatible technologies used in radio transmission.
Extensible Authentication Protocol (EAP): An authentication protocol that supports multiple
authentication methods, such as Kerberos, passwords, or smart cards. Cisco's authentication
protocol, LEAP, is based on EAP, an extension to PPP (Point-to-Point Protocol).
Encryption: Scrambling data so that only the authorized recipient can read it. Usually a key is
needed to decrypt the data.
Extended Service Set IDentifier (ESSID): A type of unique identifier applied to both the AP
and the wireless PC Card that is attached to each packet. This allows the AP to recognize each
wireless client and its traffic.
Frequencies: Strike a piano key and you generate a tone. Pick up the tone with a microphone
and your tone turns in to a “vibrating” or “cycling” electronic signal. The rate of vibration
depends on the key struck. In electronics we refer to this rate of vibration as the number of
“cycles per second.” The formal term for this value is Hertz. As we move up in rate, such as in
the Broadcast Band, we can use Kilohertz (KHz) to represent 1,000 Hz, or Megahertz (MHz) to
represent 1,000,000 Hz. Continuing much further upward, we finally reach 1,000,000,000 Hz,
which we can fortunately shorten to a Gigahertz (GHz). These frequencies are the home of both
802.11a (5 GHz) and 802.11b (2.4 GHz).
Independent Basic Service Set Identifier (IBSSID): Used to identify a wireless network
configured to allow each wireless client to communicate directly with each other without an
access point.
Independent Network: A network that provides (usually temporarily) peer-to-peer connectivity
without relying on a complete network infrastructure.
Infrastructure Mode: A wireless network centered around an access point. In this environment,
the access point not only provides communication with the wired network but also mediates
wireless network traffic in the immediate neighborhood.
Institute of Electrical and Electronics Engineers (IEEE): An organization involved in setting
computing and communications standards.
ISM Bands: A series of frequency bands, set aside by the FCC for Industrial, Scientific and
Medical applications. Users of these bands operate equipment on a shared basis, meaning that
they must expect, and accept interference from other legal users. Products manufactured for
ISM Band use must be approved by the FCC, but the user does not have to be licensed. In
addition to WLAN, ISM bands support cordless phones, microwave ovens, baby monitors, toys,
ham radio transceivers, and other wireless services.
Kerberos: An authentication system enabling protected communication over an open network
using a unique key called a ticket.
Media Access Control (MAC) Address: A hardwired address applied at the factory. It uniquely
identifies network hardware, such as a wireless PC Card, on a LAN or WAN.
Microcell: A bounded physical space in which a number of wireless devices can communicate.
Because it is possible to have overlapping cells as well as isolated cells, the boundaries of the
cell are established by some rule or convention.
Microwave: Technically, the term describes any frequency above 1.0 GHz. Unfortunately the
advertising industry has contorted this meaning considerably. In our discussion we will stick to
the technical definition.
Multipath: The signal variation caused when radio signals take multiple paths from transmitter
to receiver.
Orthogonal Frequency Division Multiplexing (OFDM): A modulation technique for
transmitting large amounts of digital data over radio waves. 802.11a uses OFDM, as will
802.11g.
Peer-to-Peer Mode: A wireless network structure that allows wireless clients to communicate
with each other without using an access point.
Personal Area Network (PAN): A personal area network, or PAN, is a networking scheme that
enables computing devices such as PCs, laptop computers, handheld personal computers,
printers and personal digital assistants (PDAs) to communicate with each other over short
distances either with or without wires.
Preamble: A preliminary signal transmitted over a WLAN to control signal detection and clock
synchronization.
Radio Frequency (RF) Terms (GHz, MHz, Hz): The international unit for measuring frequency
is Hertz (Hz), which is equivalent to the older unit of cycles per second. One Mega-Hertz (MHz)
is one million Hertz. One Giga-Hertz (GHz) is one billion Hertz. For reference: the standard US
electrical power frequency is 60 Hz, the AM broadcast radio frequency band is 0.55 -1.6 MHz,
the FM broadcast radio frequency band is 88-108 MHz, and microwave ovens typically operate
at 2.45 GHz.
Range: The distance over which a given system can communicate. This subject is discussed in
detail below.
RC4: An encryption algorithm designed at RSA Laboratories; specifically, a stream cipher of
pseudo-random bytes that is used in WEP encryption.
Remote Authentication Dial-In User Service (RAID): An authentication and accounting
system that verifies users' credentials and grants access to requested resources.
Roaming: Movement of a wireless node between two microcells. Roaming usually occurs in
infrastructure networks built around multiple access points.
Service Set Identifier (SSID): Used to identify clients on a wireless network.
Shared key An encryption key known only to the receiver and sender of data.
Site Survey: A process where you set up one transceiver in a fixed location, and then use
another unit to plot the field strength of the first unit’s transmitted signal. By moving the
transmitter around, and repeating the plots, you can develop a plan as to the best locations for
access points. You will also identify dead zones and other areas in need of special attention.
This can be a long, slow process, but it beats ripping up an unsatisfactory installation and
starting over. These tests require special software commands. Refer to your manual for specific
instructions. If you have a very large, or unusually complex installation situation, you might want
to consider calling in professionals to do your survey. We are not permitted to suggest installer
names, but you can check your yellow pages or similar sources for likely candidates.
Transceiver: A commonly used term that describes a combination transmitter and receiver.
Both 802.11a and 802.11b devices would be properly described as data transceivers.
UNII Bands: Unlicensed National Information Infrastructure. In contrast to the ISM bands, these
are a group of frequency bands set aside by the FCC for WLAN type communications only.
Users must accept interference from other legal WLAN users, but the other sources of
interference problems are, or legally should be, missing.
WECA: The Wireless Ethernet Compatibility Alliance...
WEP64 and WEP128: Wired Equivalent Privacy, 64 bit and 128 bit (64 bit is sometimes
referred to as 40 bit). This is a low-level encryption technique designed to give the user about
the same amount of privacy that he would expect from a LAN. It is extremely important to
understand that WEP is not some CIA-proof supercode! It performs as intended, giving the user
a simple level of data security and protection from casual electronic eavesdropping. Use of the
128 bit option at all possible times is recommended. Remember that 802.11 devices transmit
(broadcast) in all directions, and that it is possible, with very complex software, to copy and
decode WEP transmissions. The task is not trivial, but it is possible. If your data is extremely
sensitive, you should consider some form of secondary protection, such as strong passwords
and an additional level of encryption. Suitable software packages are available from reputable
suppliers. Although not intended by the original architects, WEP also prevents unauthorized
access to your system by an outsider. Hackers have been known to access systems from
outside a building, and to then to access the Web for a leisurely session, all at the system
owner’s expense.
Wide Area Network (WAN): A wide area network (WAN) is a voice, data, or video network that
provides connections from one or more computers or networks within a business to one or more
computers or networks that are external to such business.
Wireless: A microwave transceiver system.
Wireless LAN (WLAN): Wireless LAN is a type of local-area network that uses high-frequency
radio waves rather than wires to communicate between nodes. WLAN is a flexible data
communication system used as an alternative to, or an extension of a wired LAN.
Wireless Node: A user computer with a wireless network interface card (adapter).
