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.

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.

Fig. 2 An Example of Infrastructure Wireless LAN

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.

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 conne cts 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 in formation 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 envi ronment.

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 confl i ct with other IP addres s 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 Speci fications. Basic Rate ― the data rate of the AP with the value 1,2,5.5 or 11 Mbps for your selection.

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 ap p lication 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 statio n 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.
