Wireless LAN Overview
The wireless LAN is a new way to extend the reach of local area networks (LAN). Instead
of plugging into a LAN wall outlet, you connect wirelessly to a wireless LAN access point.
All you need is a wireless LAN card for the user and a wireless LAN access point
connected to the Ethernet LAN. This enables truly wireless access to the LAN and the
Internet. Wireless LAN users can enjoy the freedom of being automatically connected to
the LAN and of mobile computing without any attached cables. Wireless LAN is fast and
convenient: no more cables or searching for LAN outlets.

Configuring Your WLAN card
We offer a convenient utility which allows users to configure all the WLAN
parameters and to monitor the current signal quality.
Run the SETUP.EXE under the UsrCfg directory, and follow the instruction to
complete the installation. Then reboot your computer. Whenever your USB WLAN
card is connected to the PC, you can find a small icon appearing in the bottom right
corner of the tool bar as in the following figure:
If the WLAN card is successfully associated with an AP, the icon is in blue color. If
there is no AP, the AP is out of the range, or there is any mistake happening, the icon
is in red color. Click the icon to pop up the configuration/monitor box:
![](/img.php?id=178834&img=bg14.png)
Winmate Communication Inc. User Guide Feb 12, 2001

If the card is associated to an AP, a message “Associated to AP with BSSID
xx-xx-xx-xx-xx-xx” will appear, where the 12 digit HEX number is the MAC address
of the AP. The signal strength will show up in the middle of the box as a blue bar. The
Successful and unsuccessful Tx and Rx frames also show up.
You can select the communication mode between Ad-hoc mode and Infrastructure
mode by click “change” button to make changes. In the Ad-hoc mode, for every
station participating in a Network the user must select the same channel and rate (1, 2,
5.5, or 11Mbps).
In the infrastructure mode, you do not need to specify the channel. Instead, you need
to configure the ESSID.
ESSID is used in the infrastructure mode to enroll the station to the AP. One can
![](/img.php?id=178834&img=bg15.png)
Winmate Communication Inc. User Guide Feb 12, 2001

specify ESSID up to 32 characters. Please note that it is case sensitive (i.e.,
WINMATE is different from Winmate or winmate). If you want your station to
connect to the wired network through an AP, you should obtain the ESSID of that AP
from your system administrator. You can enter “ANY” (which is also the default
value) as the ESSID, and the WLAN card will search for an available AP, if there is
any, to associate with.
Select the Transmission rate. This will not affect the receiving rate because the rate of
the receiving station is determined by that of the transmission station.
WEP stands for Wired Equivalent Privacy. It served like a network password and is an
optional information to add the security of the wireless communication. The stations,
either in Ad-Hoc mode or Infrastructure mode, should have the same WEP to
associate with the other station. Please bear in mind that the WEP keys must be in
HEX and in two characters per byte formats. You can store up to four sets of WEP
KEYs in the field WEP KEY #1 to WEP KEY #4, and select among one of them in
the field WEP KEY, or simply use the value “None” if you do not want the WEP
option.
Now you can enjoy the convenience and speed of wireless connection to the network!

FAQ
Q1. What is an AP (Access Point )?
Ans: An AP is the bridge to connect two different protocols, Ethernet 802.3 and
wireless 802.11b. It can stand alone as the center of a wireless infrastructure,
providing connections to your wired networks. Or, it can act as a repeater, increasing
wireless communication range. The maximum communication range is based on how
you configure your wireless infrastructure. If your purpose is merely transferring files
between two nearby computers, you can connect these two PCs by two WLAN cards
through ad-hoc mode (explained below) without using an AP.
Q2. Please explain "infrastructure" mode and "ad hoc" mode.
Ans: The 802.11 standard defines two modes: infrastructure and ad-hoc. In the
infrastructure mode, the wireless network consists of at least one access point
connected to the wired network infrastructure and a set of wireless end stations. The
ad-hoc mode is a peer-to-peer LAN. It is a set of 802.11 wireless stations that
communicate directly with one another without using an access point or any
connection to a wired network. This mode is useful for quickly and easily setting up a
wireless network anywhere that a wired infrastructure does not exist or is not required
for service.
Q3. What is the maximum transmission rate among WLAN cards?
Ans. In 802.11b, the theoretical maximum transmission rate is 11Mbps. It also
supports 1Mbps, 2Mbps, and 5.5Mbps rates when the transmission condition is not
very good. If you have more than two wireless stations connecting on the same
channel, the 11Mbps rate would be shared by these stations.
Q4. What does the “channel selection” mean in your driver?
Ans: In 802.11 there are total of 14 channels within the 2.4GHz to 2.4835 GHz
bandwidth. If you are working under the “ad hoc" mode, you have to assign one of
the channel. All PCs in this group should be configured to this assigned channel so
that your group could form up. If you are using the infrastructure mode, the system
administrator would have set a specific channel for the AP, and the client stations can
auto detect that channel to associate with it. In the latter case, the channel selection in
the driver does not matter.
Q5. What OS can your driver support?
![](/img.php?id=178834&img=bg17.png)
Winmate Communication Inc. User Guide Feb 12, 2001
23
Ans: Our device driver uses NDIS 5, which support Windows 98 and Windows 2000.
Linux driver will be ready soon.
Q6. Does the radio wave emitting from a WLAN card have any threat to human
health?
Ans: To date, scientific studies have been unable to attribute adverse health effects to
WLAN transmissions. As with other wireless technologies, WLANs must meet
stringent government and industry standards for safety. In addition, it is expected that
any health effects related to radio transmissions would be correlated to power of the
transmitter, and the output power of WLAN system is limited by FCC regulations to
under 100mW, much less than that of a mobile phone.

WLAN Glossary
Access Point (AP)
A device that transports data between a wireless network and a wired network
(infrastructure).
ad-hoc network
A wireless network composed only of stations (no access point). Also known as peer
to peer network
application layer
The top layer of OSI seven layers. It establishes communications with other users and
provides such services as file transfer and electronic mail to the end users of the
network.
association service
An IEEE 802.11 service that enables the mapping of a wireless station to the
distribution system via an access point.
authentication
The process a station uses to announce its identity to another station. IEEE 802.11
specifies two forms of authentication: open and shared key.
bandwidth
Specifies the amount of the frequency spectrum that is usable for data transfer. In
other words, it identifies the maximum data rate that a signal can attain on the
medium without encountering significant attenuation.
baseband
A signal that has not undergone any shift in frequency. Normally with LANs, a
baseband signal is purely digital.
Basic Service Set (BSS)
A set of 802.11-compliant stations that operates as a fully connected, wireless
network.
BSSID
A 6-byte address that distinguishes a particular AP from others. Also known as a
network ID or the MAC address of the AP.
![](/img.php?id=178834&img=bg19.png)
Winmate Communication Inc. User Guide Feb 12, 2001
25
Cyclic Redundancy Check (CRC)
An error-detection process that (at the transmitting station) divides the data being sent
by a particular polynomial and appends the resulting remainder to the transmitted
data.
Data link layer
The bottom second layer of the OSI layers. It provides synchronization and
transmission error control to packets. In 802.11 LANs, it encompasses the logical link
control (LLC) and medium access control (MAC) layers.
Differential quadrature phase shift keying (DQPSK)
A modulation process that the IEEE 802.11 direct sequence physical layer uses to
transmit data. It operates at a specific center frequency and varies the phase of the
signal to represent double-bit symbols.
Direct sequence spread spectrum (DSSS)
Combines a data signal at the sending station with a higher data rate bit sequence,
which many refer to as a chip sequence (aka. processing gain). A high processing gain
increases the signal’s resistance to interference.
Extended Service Set (ESS)
A collection of basic service sets tied together via a distribution system.
Frequency hopping spread spectrum (FHSS)
Takes the data signal and modulates it with a carrier signal that hops from frequency
to frequency as a function of time over a wide band of frequencies.
IEEE 802.X
A set of specifications for Local Area Networks (LAN) from The Institute of
Electrical and Electronic Engineers (IEEE). Most wired networks conform to 802.3,
the specification for CSMA/CD based Ethernet networks. The 802.11 committee
completed a standard for 1 and 2 Mbps wireless LANs in 1997 that has a single MAC
layer for the following physical-layer technologies: Frequency Hopping Spread
Spectrum, Direct Sequence Spread Spectrum, and Infrared. IEEE 802.11 b, an 11
Mbps version of the standard, was finalized at the end of 1999.
Independent Basic Service Set Network (IBSS Network)
A 802.11-based wireless network that has no backbone infrastructure and consists of
![](/img.php?id=178834&img=bg1a.png)
Winmate Communication Inc. User Guide Feb 12, 2001
26
at least two wireless stations. This type of network is often referred to as an ad hoc
network because it can be constructed quickly without much planning.
Industrial, Scientific, and Medicine bands (ISM bands)
Radio frequency bands that the Federal Communications Commission (FCC)
authorized for wireless LANs. The ISM bands are located at 902 MHz, 2.400 GHz,
and 5.7 GHz.
Infrastructure network
A wireless network centered about 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.
Logical Link Control (LLC) layer
The highest layer of the IEEE 802 reference model, providing similar functions of a
traditional data link control protocol.
Medium Access Control (MAC) layer
Provides medium acess services for IEEE 802 LANs.
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.
Multipath
The signal variation caused when radio signals take multiple paths from transmitter to
receiver.
narrowband system
A wireless system that uses dedicated frequencies assigned by the FCC licenses. The
advantage of narrowband system is that if interference occurs, the FCC will intervene
and issue an order for the interfering source to cease operations.
NetBIOS
A standard interface between networks and PCs that allows applications on different
computers to communicate within a LAN. It was created by IBM for its early PC
![](/img.php?id=178834&img=bg1b.png)

network, was adopted by Microsoft, and has since become a de facto industry
standard. It is not routable across a WAN.
open system authentication
The IEEE 802.11 default authentication method, which is a very simple, two-step
process. First the station wanting to authenticate with another station sends an
authentication management frame containing the sending station’s identity. The
receiving station then sends back a frame alerting whether it recognizes the identity of
the authenticating station.
Open System Interconnection (OSI)
An ISO standard specifying an open system capable of enabling the communications
between diverse systems. It has the following seven layers of distinction: physical,
data link, network, transport, session, and application. These layers provide the
functions necessary to allow standardized communications between two application
processes.
peer-to-peer network
A network where there are communications between a group of equal devices. A
peer-to-peer LAN does not depend on a dedicated server, but allows any node to be
installed as a non-dedicated server and share its files and peripherals across the
network.
physical layer
Provides the transmission of bits through a communication channel by defining
electrical, mechanical, and procedural specifications.
Point Coordination Function (PCF)
An IEEE 802.11 mode that enables contention-free frame transfer based on a priority
mechanism. Enables time-bounded services that support the transmission of voice and
video.
Quadrature Phase Shift Keying (QPSK)
A modulation technique that changes the phase of a signal to represent different,
four-bit binary words.
Radio Frequency (RF) Terms: GHz, MHz, Hz
![](/img.php?id=178834&img=bg1c.png)
Winmate Communication Inc. User Guide Feb 12, 2001
28
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.
reassociation service
Enables an IEEE 802.11 station to change its association with different access points
as the station moves throughout the facility.
roaming
Movement of a wireless node between two microcells. Roaming usually occurs in
infrastructure networks built around multiple access points.
shared key authentication
A type of authentication that assumes each station has received a secret shared key
through a secure channel independent from an 802.11 network. Stations authenticate
through shared knowledge of the secret key. Use of shared key authentication requires
implementation of the 802.11 WEP algorithm.
spread spectrum
A modulation technique that spreads a signal’s power over a wide band of frequencies.
The main reasons for this technique are that the signal becomes much less susceptible
to electrical noise and interferes less with other radio-based systems.
Transmission Control Protocol (TCP)
A commonly used protocol for establishing and maintaining communications between
applications on different computers. TCP provides full-duplex, acknowledged, and
flow-controlled service to upper-layer protocols and applications.
Wired Equivalent Privacy (WEP)
An optional IEEE 802.11 function that offers frame transmission similar to a wired
network. The WEP generates secret shared encryption keys that both source and
destination stations can use to alter frame bits to avoid disclosure to eavesdroppers.
