Quick Installation Guide
Hardware Description
Ethernet Compatibility
Accton’s Wireless Access Point can attach directly to 10BASE-T/100BASE-TX
(twisted-pair) Ethernet LAN segments. These segments must conform to the IEEE 802.3
specification.
The access point appears as an Ethernet node and performs a routing function by moving
packets from the wired LAN to remote workstations on the wireless infrastructure.
Radio Characteristics
The Wireless Access Point uses a radio modulation technique known as Orthogonal
Frequency Division Multiplexing (OFDM), and a shared collision domain (CSMA/CA).
It operates at the 5 GHz Unlicensed National Information Infrastructure (UNII) band with
turbo mode. Data is transmitted over a half-duplex radio channel operating at up to
72 Megabits per second (Mbps) in the turbo mode, and with a maximum operating range
up to 500 m (1650 feet).
LED Indicators
The Wireless Access Point includes three status LED indicators, as described in the
following figure and table.

Quick Installation Guide
Identification
The SSID (Service Set Identification) is the name of a basic service set provided by an
access point. All clients that want to connect to the Internet via an access point must set
their SSIDs to the same as that of the access point.
SSID: This should be set to the same value as other wireless devices in your network.
(Default: ANY).
Channel
Radio Channel: The radio channel through which the access point communicates to PCs
in its BSS (page 25). Note that the radio channel for wireless clients is automatically set to
the same as that used by the access point to which it is linked. (Default: 52 for US and 38
for Japan)
Note: The available channel settings are limited to local regulations, which determine
the number of channels that are available.
• FCC: 8 channels
• MKK: 5 channels
12
Advanced Setup
Turbo Mode: You may either Enable or Disable the Turbo Mode. (Default: Disable)
Turbo Mode is the enhanced wireless LAN operating mode (not regulated in the standard
IEEE 802.11a) that can provide a higher data rate. The Normal Mode of the 802.11a
access point provides connections up to 54 Mbps. Enabling Turbo Mode on the 802.11a
access point allows the access point to provide connections with a data rate of up to
72 Mbps.
Note: In Normal Mode, the channel bandwidth is 20 MHz. In Turbo Mode, the channel
bandwidth is increased to 40 MHz. However, there are only three channels
available when the Turbo Mode is enabled (only 1 channel in Japan).
Performance
Data Rate: Select “best” from the drop-down list to optimize the data transfer speed for
your network. (Default: best)
Transmit Power: Set the signal strength transmitted from the access point. The longer
the transmission distance, the higher the transmission power required. (Default: full)
13
Quick Installation Guide
Synchronization
In order to obtain transmission, the access point and connected clients need to be
synchronized
.
Beacon Interval (20-1000 Kµs): Set the beacon interval between synchronization frames.
These synchronization frames may also contain an indication of frames that are to be
transmitted to stations in Power Save mode. (Default: 100)
Note: 1Kµs = 1000 microsecs = 1 ms
DTIM (1-16384): Set the Delivery Traffic Indication Message (DTIM) interval. The DTIM
indicates how often the MAC layer forwards multicast traffic. This parameter is necessary
to accommodate stations using Power Save mode. In order to maximize the utilization of
channels, broadcast data is not transmitted after every beacon interval for stations in
Power Save mode. These stations must wake up to receive broadcast data at the DTIM
interval.
The DTIM is the interval between two synchronization frames with broadcast information.
If you set the value to 2, the access point will save all multicast frames for the BSS and
forward them after every second beacon interval. Smaller DTIM intervals deliver multicast
frames more frequently, causing stations in Power Save mode to wake up more often and
drain power faster. Higher DTIM intervals delay the transmission of multicast frames.
(Default: 1)
14
Advanced Setup
Transmit Threshold
Fragment Length (256-2346): The Fragment Length can be set between 256 and 2,346.
If the packet size is smaller than the preset fragment size, the packet will not be
segmented.
Fragmentation of the packets can increase the reliability of transmission because it
increases the probability of a successful transmission due to smaller frame size. If there is
significant interference present or collisions due to high network utilization, try setting the
fragment size to a smaller value. This will enable the retransmission of smaller frames
much faster. However, it is more efficient to set a longer fragment length if very little or no
interference is present because there are overhead costs in sending multiple frames.
(Default: 2346)
RTS Length (256-2346): Set the RTS (Request to Send) frame length.
You may configure the access point to initiate an RTS frame sequence always, never, or
only for frames longer than a specified length. If the packet size is smaller than the preset
RTS threshold size, the RTS/CTS mechanism will NOT be enabled
The access point sends request to send (RTS) frames to a particular receiving station to
negotiate the transmission of a data frame. After receiving an RTS, the station sends a
CTS (Clear to Send) frame to acknowledge the right for the sending station to transmit
data frames. Access points contending for the medium may not be aware of each other.
The RTS/CTS mechanism can solve this “Hidden Node Problem.” (Default: 2346)
15
Quick Installation Guide
TCP / IP Settings
Set the TCP/IP configuration for accessing the Internet.
DHCP Client: If Enable is selected, the IP address, subnet mask and default gateway can
be dynamically assigned to the access point by the network DHCP server.
(Default: Disable)
Note: If there is no DHCP server on your network, then the access point will
automatically start up with its default IP address, 192.168.1.20.
By using the Wireless Access Point’s built-in DHCP (Dynamic Host Configuration
Protocol) server, you are allowing the Wireless Access Point to handle all the IP
addressing on your Local Area Network (LAN). This can save you much of the time and
hassle of setting up your network.
DHCP Server: If you have a server on your network that requires a static IP address,
select Enable under DHCP Server and then manually assign a static IP address to your
server. (Default: Disable)
16
Advanced Setup
Encryption
For more secure data transmission, you may enable WEP (Wired Equivalent Privacy) to
prevent unauthorized access to your wireless network. The WEP setting must be the
same for each client in your wireless network.
17
Quick Installation Guide
Authentication Type
You may choose either the Open System or the Shared Key. (Default: Open System)
If Shared Key is enabled, WEP should be enabled and at least one shared key should be
defined. But you can enable WEP, and set the authentication type as Open System.
Standard WEP Setup (WEP Default: Disable)

Using Access Control List
Set the Access Control List (ACL) to filter out specified MAC addresses. The ACL
provides a mechanism to take certain actions based on the stations MAC address. Any
frames with a source or destination MAC address entered in this table will be filtered from
the access point.
Hex Digits per Key ID
10 HEX digits
18
Advanced Setup
How to Set up the Access Control List:
1. Select ACL Enable
2. Enter an ACL ID (1 ~ 60)
3. Enter the MAC address of the station you want to set up.
4. Enter a Key Map, one of the shared keys (1 ~ 4) or one of the unique keys (5 ~ 64),
and choose Allow or Deny. If the station’s WEP key is the same as the Key Map you
assigned, the station will then allow or deny connections to the access point.
5. If you just enable the ACL, all stations that have shared keys can also connect to the
access point. If you set the ACL to Strict, only stations with MAC addresses in the ACL
can connect to the access point.
SNMP
Use this screen to display and enter a community string for the Simple Network
Management Protocol (SNMP). To communicate with the access point, the SNMP agent
must first be enabled, and the Network Management Station must submit a valid
community string for authentication.

Network Configuration and Planning
Accton’s Cheetah wireless solution supports a stand-alone wireless network
configuration, as well as an integrated configuration with 10/100 Mbps Ethernet LANs.
The Accton wireless network cards, adapters, access points and Wireless Access Point
can be configured as:
• Ad hoc - for small groups that only communicate with each other
• Infrastructure - for wireless LANs
• Infrastructure wireless LAN - for roaming wireless PCs
Network Topologies
Ad Hoc Wireless LAN (no AP or Bridge)
An ad hoc wireless LAN consists of a group of computers, each equipped with a wireless
adapter, connected via radio signals as an independent wireless LAN. Computers in a
specific ad hoc wireless LAN must therefore be configured to the same radio channel. An
ad hoc wireless LAN can be used in a SOHO or temporary environment.

Network Topologies
Infrastructure Wireless LAN
The WA5001 can also provide access to a wired LAN for wireless workstations. An
integrated wired/wireless LAN is called an infrastructure configuration. A Basic Service
Set (BSS) consists of a group of wireless PC users, and an access point that is directly
connected to the wired LAN. Each wireless PC in this BSS can talk to any computer in its
wireless group via a radio link, or access other computers or network resources in the
wired LAN infrastructure via the access point.
The infrastructure configuration not only extends the accessibility of wireless PCs to the
wired LAN, but also increases the effective wireless transmission range for wireless PCs
by passing their signal through one or more access points.
A wireless infrastructure can be used for access to a central database, or for connection
between mobile workers, as shown in the following figure.

Infrastructure Wireless LAN for Roaming Wireless PCs
The Basic Service Set (BSS) is the communications domain for each Wireless Access
Point. For wireless PCs that do not need to support roaming, set the domain identifier
(SSID) for the wireless card to the BSS ID of the access point to which you want to
connect. Check with your administrator for the BSS ID of the access point or bridge to
which he wants you to connect.
A wireless infrastructure can also support roaming for mobile workers. More than one
access point can be configured to create an Extended Service Set (ESS). By placing the
access points so that a continuous coverage area is created, wireless users within this
ESS can roam freely. All Accton wireless network cards and adapters and WA5001
Wireless Access Points within a specific ESS must be configured with the same SSID.

Terminology
Terminology
The following is a list of terminology that is used in this document.
Access Point
networks.
Ad Hoc
connected as an independent wireless LAN.
Backbone
transports information from one central location to another central location where it is
unloaded onto a local system.
Base Station
transmitter/receiver that maintains communications with the mobile radiotelephone sets
within its range. In cellular and personal communications applications, each cell or
micro-cell has its own base station; each base station in turn is interconnected with other
cells’ bases.
BSS
– BSS stands for “Basic Service Set.” It is an access point and all the LAN PCs that
are associated with it.
CSMA/CA
ESS
– ESS (ESS-ID, SSID) stands for “Extended Service Set.” More than one BSS is
configured to become an Extended Service Set. LAN mobile users can roam between
different BSSs in an ESS (ESS-ID, SSID).
Ethernet
transmission from computers and terminals. Ethernet operates on a 10 Mbps base band
transmission rate, using a shielded coaxial cable or over shielded twisted pair wire.
Infrastructure
configuration.
Roaming
continuous connection to the Infrastructure network.
RTS Threshold
other. RTS/CTS mechanism can solve this “Hidden Node Problem.” If the packet size is
smaller than the preset RTS Threshold size, the RTS/CTS mechanism will NOT be
enabled.
WEP
– Wired Equivalent Privacy is based on the use of 64-bit, 128-bit or 152-bit keys
and the popular RC4 encryption algorithm.
– An internetworking device that seamlessly connects wired and wireless
– An ad hoc wireless LAN is a group of computers each with LAN adapters,
– The core infrastructure of a network. The portion of the network that
– In mobile telecommunications, a base station is the central radio
– Carrier Sense Multiple Access with Collision Avoidance.
– A popular local area data communications network, which accepts
– An integrated wireless and wired LAN is called an infrastructure
– A wireless LAN mobile user moves around an ESS and maintains a
– Transmitters contending for the medium may not be aware of each
