Chapter 1 Introduction

IEEE 802.11g uses 2.4GHz unlicensed ISM band, the same as IEEE 802.11b; but it provides
almost 5 times data rate than traditional 802.11b products. WL-8310 is compliant to both

802.11b and 802.11g, but it is capable to offer much higher data rate than standard. With the
latest innovative Super G technology integrated, the maximum data rate of WL-8310 is
108Mbps, which doubles the speed of standard 802.11g. Thus makes WL-8310 more suitable
for multimedia applications which required more bandwidth.
The WL-8310 is provided with a detachable dipole antenna that can be replaced with optional
external antennas to obtain better signal quality and greater connection distances.
The WL-8310 supports both 64/128-bit WEP (Wired Equivalent Privacy) and Wi-Fi Protected
Access (WPA) for securing wireless network connections. The driver and utility supports most
popular operating systems: Windows 98SE/ME/2000/XP/Server 2003. With advanced features
and high performance capability, the WL-8310 is an excellent choice for constructing a wide
range of wireless solutions.

1.2 Applications

1.2.1 Infrastructure

The WL-8310 provides access to a wired LAN for wireless workstations. An integrated

1

wireless and wired LAN is called an Infrastructure configuration. A group of WL-8310 PC
users and an Access Point compose a Basic Service Set (BSS). Each WL-8310 PC in a
BSS can talk to any computer in the wired LAN infrastructure via the Access Point.
An Infrastructure configuration extends the accessibility of a WL-8310 equipped PC to a
wired LAN, and doubles the effective wireless transmission range for 2 WL-8310 PCs.
Since the Access Point is able to forward data within its BSS, the effective transmission
range in an infrastructure LAN is doubled.
The use of a unique ID in a BSS is essential. All WL-8310 equipped PCs configured
without roaming options in an independent BSS must be configured with a BSS ID
corresponding to the WL-8310 used in the BSS. Check your WL-8310 for its BSS ID or
use the Site Survey function on Configuration Utility program to determine the BSS ID.
The Infrastructure Wireless LAN configuration is appropriate for enterprise-scale
wireless access to a central database, or as a wireless application for mobile users.
Infrastructure mode also supports roaming capabilities for mobile users. More than one
BSS can be configured as an Extended Service Set (ESS). The continuous network
allows users to roam freely within an ESS. All WL-8310 PCs or other IEEE 802.11b and

802.11g compliant wireless adapters within one ESS must be configured with the same
ESS ID and use the same radio channel.
Before enabling an ESS with roaming capability, choosing a feasible radio channel and
optimum Access Point position is recommended. Proper Access Point positioning
combined with a clear radio signal will greatly enhance performance.

1.2.2 Ad-Hoc

An Ad-Hoc wireless LAN is a group of computers, each equipped with one WL-8310
adapter or other wireless adapters, connected as an independent wireless LAN.
Computers in a specific Ad-Hoc wireless LAN must be configured to share the same
radio channel.
Ad-Hoc wireless LAN configurations are appropriate for branch level departments or
SOHO operations.

2

1.2.3 General Application

WL-8310 offers a fast, reliable, cost-effective solution for wireless client access to the
network in applications like these:

1. Remote access to corporate network information

E-mail, file transfer and terminal emulation.

2. Difficult-to-wire environments

Historical or old buildings, asbestos installations, and open area where wiring is
difficult to employ.

3. Frequently changing environments

Retailers, manufacturers and banks who frequently rearrange the workplace and
change location.

4. Temporary LANs for special projects or peak time

Trade shows, exhibitions and construction sites need temporary setup for a short time
period. Retailers, airline and shipping companies need additional workstations for a
peak period. Auditors require workgroups at customer sites.

5. Access to database for mobile workers

Doctors, nurses, retailers, white-collar workers need access to database while being
mobile in the hospital, retail store or office campus.

6. SOHO (Small Office and Home Office) users

SOHO users need easy and quick installation of a small computer network.

7. High security connection

The wireless security network installs quickly and provides the flexibility to reconfigure
easily.

Ø Continuous Access Mode: WL-8310 will always set in active mode.

Ø Maximum Power Save: WL-8310 will enter power saving mode when it is idle.

Ø Power Save: WL-8310 consumes the moderate level of power.
u Preamble: There is two options can be selected: Short & Long Preamble, Long

Preamble. Preamble is a sequence of bits transmitted at 1Mbps that allows the PHY

circuitry to reach steady-state demodulation and synchronization of bit clock and frame

start. Two different preambles and headers are defined: the mandatory supported Long

Preamble and header, which interoperate with the 1 Mbit/s and 2 Mbit/s DSSS

specification (as described in IEEE 802.11), and an optional Short Preamble and header

13

(as described in IEEE 802.11b). At the receiver, the Preamble and header are processed

to aid in demodulation and delivery of the PSDU. The Short Preamble and header may

be used to minimize overhead and, thus, maximize the network data throughput.

However, the Short Preamble is supported only from the IEEE 802.11b (High-Rate)

standard and not from the original IEEE 802.11. That means that stations using

Short-Preamble cannot communicate with stations implementing the original version of

the protocol.
u Support Band: The supported bands of WL-8310 are 11B, 11G, and 11G Turbo (11A and

11A Turbo are preserved for future usage). With all options selected, WL-8310 can keep

the highest flexibility when making connection to AP. If you fix the WLAN band for both

AP and WL-8310, it can skip the initial negotiation time.

3.3 Advanced

Additional security can be achieved by using any of the following encryption methods: WEP
(Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and WPA-PSK (Pre Shared Key).
When “Enable” is selected in “Encryption” field, WEP encryption is activated. Please enter
the appropriate parameters to these fields.

u Auth. Mode:

Ø Auto: With this setting, stations can communicate with the Access Point either with or

without data encryption. It will detect the AP that it connected is using which Authentication
mode and use the same mode to communicate.

Ø Open Authentication: With this setting, the station in the WLAN can receives and

transmits data from Access Point (null authentication).

Ø Shared Authentication: With this setting, allows communication only with other devices

with identical WEP settings.

three modes, each mode has two kind of key length and that is decide on the Key
Format you selected. 64bit (5ASCII / 10HEX.), 128bit (13ASCII / 26HEX).

u Key Format – You can select WEP key format to HEX (Hexadecimal code, 0-9, A-F) or

ASCII (American Standard Code for Information Interchange, 0-9, a-z, A-Z).
When “WPA” is selected in “Encryption” field, please click “Configuration” button for

advanced settings.

WPA uses 802.1x and Extensible Authentication Protocol (EAP) as the basis of its
authentication mechanism. Thus your computer needs to install a certification for the RADIUS
server first. Please consult with your network administrator for getting the certification and the
appropriate parameters of the above screen.
When “WPA-PSK” is selected in “Encryption” field, please click “Configuration” button and

Appendix

This section provides some technology Q&A. Read the description below to know more about
the wireless network.

ü What is the difference between 54Mbps and 11Mbps wireless products? What’s the

benefit of 54Mbps Wireless Access Point?

The 54Mbps is made possible by the new modulation method called OFDM, which is
different from the current CCK modulation method for 11Mbps. The 54Mbps wireless
products also operate in the 2.4GHz ISM band and they are backward compatible with
11Mbps wireless products.

ü What is ISM band?

The FCC and their counterparts outside of the U.S. have set aside bandwidth for
unlicensed use in the ISM (Industrial, Scientific and Medical) band. The 2.4GHz
unlicensed ISM band is available worldwide, which presents the opportunity for the
global market of 802.11b and 802.11g high speed wireless products.

ü What is Ad-Hoc?

An Ad-Hoc integrated wireless LAN is a group of computers, each with a WLAN adapter,
Connected as an independent wireless LAN. Ad-Hoc wireless LAN is applicable at a
departmental scale for a branch or SOHO operation.

ü What is Infrastructure?

An integrated wireless and wired LAN is called an Infrastructure configuration.
Infrastructure is applicable to enterprise scale for wireless access to central database,
or wireless application for mobile workers.

ü What is BSS ID?

A specific Ad-Hoc LAN is called a Basic Service Set (BSS). Computers in a BSS must
be configured with the same BSS ID.

ü What is Roaming?

Roaming is the ability of portable computers, e.g., Packet PC and notebook, to have
consistent and continuous data transmission/reception throughout an area covered by
more than one Wireless Access Point. In order to achieve seamless connectivity, all
the wireless clients and Access Points must be set to use the same SSID. When a
user walked out of the coverage area of one AP into another, the wireless client network
device will automatically reestablish connection with the new AP.

ü What is a MAC Address?

The Media Access Control (MAC) address is a unique number assigned by the
manufacturer to any Ethernet networking devices, e.g. a network adapter, that allows
the network to identify it at the hardware level. Unlike IP addresses, which can be

18

changed or dynamically assigned by the network, the MAC address of a networking
device is permanent.

ü What is WEP?

Wired Equivalent Privacy (WEP) is a type of data encryption mechanism described in
the IEEE 802.11 standard.

ü What is WPA (Wi-Fi Protected Access)?

WPA resolves the issue of weak WEP headers, which are called initialization vectors
(IV), and provides a way of insuring the integrity of the messages passed through MIC
(called Michael or message integrity check) using TKIP (the Temporal Key Integrity
Protocol) to enhance data encryption. WPA-PSK is a special mode of WPA for home
users without an enterprise authentication server and provides the same strong
encryption protection. WPA is not an official IEEE standard, but is based on and is
expected to be compatible with the upcoming 802.11i security standard.

ü Could I implement the driver/utility installations on another operating system, e.g.

Windows 98SE, 2000 and ME? Are there any differences of driver/utility

installations among these different operating systems?

Yes, you can. All the installation mentioned in this user’s manual could be implemented
on Windows 98SE/ME/200/XP and there will be no difference.

ü Can Wireless products support printer sharing?

Wireless products perform the same function as LAN products. Therefore, Wireless
products can work with Netware, Windows NT/2000/XP, or other LAN operating
systems to support printer or file sharing.

ü What is DSSS？What is FHSS？And what are their differences?

Frequency-hopping-spread-spectrum (FHSS) uses a narrowband carrier that changes
frequency in a pattern that is known to both transmitter and receiver. Properly
synchronized, the net effect is to maintain a single logical channel. To an unintended
receiver, FHSS appears to be short-duration impulse noise. Direct-sequence
spread-spectrum (DSSS) generates a redundant bit pattern for each bit to be
transmitted. This bit pattern is called a chip (or chipping code). The longer the chip, the
greater the probability that the original data can be recovered. Even if one or more bits
in the chip are damaged during transmission, statistical techniques embedded in the
radio can recover the original data without-the need for retransmission. To an
unintended receiver, DSSS appears as low power wideband noise and is rejected
(ignored) by most narrowband receivers.

ü What is Spread Spectrum?

Spread Spectrum technology is a wideband radio frequency technique developed by the
military for use in reliable, secure, mission-critical communication systems. It is
designed to trade off bandwidth efficiency for reliability, integrity, and security. In other

19

words, more bandwidth is consumed than in the case of narrowband transmission, but
the trade off produces a signal that is, in effect, louder and thus easier to detect,
provided that the receiver knows the parameters of the spread-spectrum signal being
broadcast. If a receiver is not tuned to the right frequency, a spread –spectrum signal
looks like background noise. There are two main alternatives, Direct Sequence Spread
Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).

ü How does WL-8310 reach the high data rate, 108Mbps?

WL-8310 is using Atheros AR5002G chipset which enhanced with Super G mode.
There are three technologies used in Super G mode. First is called Packet Bursting,
which puts more data in one single transmission. Second technology is called
Compression. The AR5002G chipset employs a special engine to compress and
encrypt data. The last technology is Combine Channel, which combines two radio
channels simultaneously for one connection. Through the above three technologies,
Super G mode can provide up to 108Mbps data rate, but the available channels will be
reduced to 6 only.
