Section 1 About GL2411AP-0A Access Point
Introduction
The GL2411AP-0A (11 Mbps WLAN Access Point) is a long-range, high performance LAN product,
which provides Access Point services to a 2,4 GHz RF network and bridges to an Ethernet backbone. The
design of this product is based on AT76C510 (bridge-on-a-chip) module, a highly integrated ASIC designed
to combine legacy LANs with wireless LANs. AT76C510 performs all the necessary inter-networking and
bridging functions. It receives data from both networks, stores them locally for further processing, installs and
maintains connections and transmits the packets to the proper destination. Furthermore, AT76C510 interfaces
three more modules, the Ethernet PHY, the wireless PHY and the RAM modules, for allowing compact
system implementation and flexibility for supporting almost all the possible physical interfaces.
1-1 Features

– WEP encryption/decryption is accomplished on the fly
– Ethernet MAC supports MII interface and 10/100Mbit speeds
– Hardware modules for Packet Filtering and statistics gathering
– Glueless SRAM, Flash interface for data buffering and program storage, supporting up to 16 MB of
memory
– Integrated 2 x 6K x 32 bit internal SRAM modules for fast 32-bit program execution and temporary
storage of data
– Supports 3V supply
– 128-pin PQFP, TQFP
– JTAG Boundary Scan (IEEE 1149.1) test access port for board-level production test

Section 2 Hardware Installation
2-1 Equipment Requirement
Installation of GL2411AP-0A requires:
1. An A/C power outlet (100~240V,50~60Hz) which will supply the power for the GL2411AP-0A Access
Point
2. A 10/100 Base-T (UTP) Ethernet cable drop (RJ-45 connector)
2-2 GL2411AP-0A Hardware Installation
Please follow these procedures while setting up the hardware:
1. Site Selection
Choose a proper place for your GL2411AP-0A.
In general, the best location to place your GL2411AP-0A is the center of your wireless coverage, with line
of sight to all your mobile stations.
2. Adjust the direction of the Antenna
Adjust the direction of the antenna placement to improve the GL2411AP-0A’s performance. Try to place
the antenna in the position which can best cover its BSS. Normally, the higher you place the antenna, the
better the performance will be. The character of diversity enhances the receiving sensitivity.
3. Connect the Ethernet Cable
GL2411AP-0A can be connected to the 10/100 Base-T Ethernet network. Connect your UTP Ethernet cable
to the RJ-45 connector of the GL2411AP-0A AP and connect the other side of UTP Ethernet cable to a hub.
4. Connect the Power Cable
Connect the power adapter cable to the DC5V Power Socket of the GL2411AP-0A. ONLY use the power
adapter supplied with the GL2411AP-0A. Otherwise, the product may be damaged.

An Ad-Hoc wireless LAN is a group of computers, each equipped with one LAN adapter, connected as
an independent wireless LAN. Computers in a specific Ad-Hoc wireless LAN must be configured at the
same radio channel and ESSID.
Ad-Hoc wireless LAN is applicable at a departmental scale for a branch or SOHO operation.

GL2411AP-0A provides access to a wired LAN for wireless workstations. An integrated wireless and
wired LAN is called an Infrastructure configuration. A group of LAN PC users and a GL2411AP-0A
Access Point construct a Basic Service Set (BSS). Each LAN PC in the BSS can talk to any computer in
the wired LAN infrastructure via the GL2411AP-0A Access Point.
Infrastructure configuration not only extends the accessibility of a LAN PC to the wired LAN, but also
doubles the effective wireless transmission range for 2 LAN PCs. Since GL2411AP-0A is able to
forward data within its BSS, the effective transmission range in an infrastructure LAN is doubled.
BSS ID is, in essence, the ID of each independent GL2411AP-0A. All LAN PCs configured without
roaming options in the independent BSS must be configured with the BSS ID of the GL2411AP-0A.
Infrastructure is applicable in an enterprise scale for wireless access to central databases, or wireless
access for mobile workers.
A-2 Roaming
Fig. 3 Roaming in an Extended Service Set (ESS)
An Infrastructure configuration also supports roaming capability for mobile workers. More than one BSS
can be configured to be an Extended Service Set (ESS). On account of a continuous connection to the
network, users within an ESS can roam freely. All LAN PCs and GL2411AP-0As within one ESS must be
configured with the same ESS ID and at the same radio channel.

Appendix C Glossary
Access Point ― An internetworking device that seamlessly connects wired and wireless networks.
Ad-Hoc ― An Ad-Hoc wireless LAN is a group of computers each with LAN adapters, connected as an
independent wireless LAN.
Backbone ― The core infrastructure of a network. The portion of the network transports information from one
central location to another central location where it is unloaded onto a local system.
Bridge ― An internetworking function that incorporates the lowest 2 layers of the OSI network protocol model.
BSS ― BSS stands for “Basic Service Set”. It is an Access Point and all the LAN PCs that associated with it.
ESS ― ESS stands for “Extended Service Set”. More than one BSS is configured to become Extended Service
Set. LAN mobile users can roam between different BSSs in an ESS.
Ethernet ― A popular local area data communications network, originally developed by Xerox Corp., that
accepts transmission from computers and terminals. Ethernet operates on a 10 Mbps baseband transmission rate,
using a shielded coaxial cable or over shielded twisted pair telephone wire.
Infrastructure ― An integrated wireless and wired LAN is called an Infrastructure configuration.
Roaming ― A LAN mobile user moves around an ESS and enjoys a continuous connection to the Infrastructure
network.
RTS Threshold ― Transmitters contending for the medium may not be aware of each 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.
DSSS ― direct sequence spread spectrum
PLCP ― physical layer convergence protocol
PPDU ― PLCP protocol data unit
PSDU ― PLCP service data unit
Ethernet Mac Address ― Don’t change it, as this will disable the AP.
Ethernet IP Address and SubMask ― Please setup them to match your network environment.
For example : If your IP address is 192.168.99.127 and your SubMask is 255.255.255.0. Please set the
IP address of the AP to 192.168.99.xx which will not have conflict with other IP address
and set the SubMask of the AP to 255.255.255.0.
Channel ― The AP and the with it associated stations will work in this channel. You must set the channel by
consulting Appendix B from violating the Specifications.
Basic Rate ― the data rate of the AP with the value 1,2,5.5 or 11 Mbps for your selection.
23
ESSID ― In infrastructure association , the stations will link to the AP with the same ESSID as they have.
WEP ― Wired Equivalent Privacy (Wep) is an encryption scheme used to protect wireless data communication.
To enable the icon will prevent other stations without the same WEP key from linking with the AP.
Preamble Type ― During transmission, the PSDU shall be appended to a PLCP preamble and header to create
the PPDU. Two different preambles and headers are defined : the mandatory supported long preamble and header
which interoperates with the current 1 and 2 Mbit/s DSSS specification as described in IEEE Std 802.11-1999,
and an optional short preamble and header. At the receiver, the PLCP preamble and header are processed to aid in
demodulation and delivery of the PSDU. The optional short preamble and header is intended for application
where maximum throughput is desired and interoperability with legacy and non short preamble capable equipment
is not consideration. That is, it is expected to be used only in networks of like equipment that can all handle the
optional mode. (IEEE 802.11b standard)
Authentication Type ― Indication of an authentication algorithm which can be supported by this node:
1. Open System : Open System authentication is the simplest of the available authentication algorithms.
Essentially it is a null authentication algorithm. Any station that requests authentication with this
algorithm may become authenticated if dot11AuthenticationType at the recipient station is set to Open
System authentication.
2. Shared Key : Shared Key authentication supports authentication of STAs as either a member of those
who know a shared secret key or a member of those who do not.
Open System authentication is the default authentication algorithm.
