1-2 Applications
The 11Mbps Wireless LAN products offer 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 deploy.
3. Frequently Changing Environments
Retailers, manufacturers and those who frequently rearrange the workplace and change
location.
4. Temporary LANs for Special Projects or Peak Time
C1- Trade shows, exhibitions and construction sites where a temporary network will be
practical. C2- Retailers, airline and shipping companies need additional workstations
during peak period. C3- Auditors requiring workgroups at customer sites.
5. Access to Database for Mobile Workers
Doctors, nurses, retailers, accessing their 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 secure wireless network can be installed quickly and provide flexibility. (Please
refer to page 14 for more information on encryption configuration.)

1-3 System Configurations
The 11Mbp Wireless Inter-Building Access Point can be configured in a variety of network
system configurations.
Wireless Infrastructure
In a wireless infrastructure, the Inter-Building Access Point acts as a bridge. The Inter-
Building Access Point connects the wireless clients together. The Inter-Building Access Point
acts as a center point for all wireless communications. This would increase efficiency of the
communications since the wireless adapters do not need to be within direct range of each
other.
Wireless Infrastructure with Stations Attaching to a Wired LAN
The 11Mbps Wireless LAN Inter-Building Access Point will provide an access to the local
LAN. An integration of wireless and wired LAN is called an Infrastructure configuration. A
group of wireless LAN PC users and an Inter-Building Access Point construct a Basic Service
Set (BSS). Each wireless PC in this BSS can talk to each other on your network via the Inter-
Building Access Point.

Ethernet Ports
The 11Mbps Wireless LAN Inter-Building Access Point supports an Ethernet ports: RJ-45
MDI daisy-chain port (labeled “MDI”). You may connect the Inter-Building Access Point
either to a hub or a PC. Please note that, use the cross-over cable when you desire to connect
the Access Point to a PC. The two LEDs (10/100/Link) next to the Ethernet ports indicate the
Ethernet physical link status. The ‘Link’ LED is a good indicator for to see if you have
proper Ethernet connection.
Default
NOTE: The button labeled “DEFAULT” enables you to restore the Access Point’s default
setting. This is used when you forget the password. Please detach the DC power plug and
press the “DEFAULT” button on the back panel of the Access Point. Reconnect the power
and keep holding the button in for a few seconds until the “AP” LED indicator blinks. This
will restore the Access Point’s default settings and enable you to configure the Access Point
via utility, telnet or Web again.

2-4 Hardware Installation
Take the following steps to set up your Inter-Building Access Point.
nSite Selection
Before installation, determine the Inter-Building Access Point location. Proper placement
of the Inter-Building Access Point is critical to ensure optimum radio range and
performance. You may use the Site Survey and Access Points Browser utility (The
utilities came with the wireless PC Card) to choose a proper placement for your Inter-
Building Access Point. Typically, the best location to place your Inter-Building Access
Point at your site is the center of your wireless coverage area. Try to place your mobile
stations within the line of sight. Obstructions may impede performance of the Inter-
Building Access Point.
nConnect the Ethernet Cable
The 11Mbps Wireless LAN Inter-Building Access Point supports 10/100M Ethernet
connection. Attach your UTP Ethernet cable to the RJ-45 connector on the Inter-Building
Access Point. Then connect the other end of the RJ-45 cable to a hub or a station. Please
note that, use the cross-over cable when you desire to connect the Access Point to a PC.
nConnect the Power Cable
Connect the power adapter to the power socket on the Inter-Building Access Point, and
plug the other end of the power into an electrical outlet. The Inter-Building Access Point
will be powered on and all five indicators on the top panel will flash in sequence to test
the functionality of the indicators.
NOTE: ONL Y use the power adapter supplied with the Inter -Building Access Point .
Otherwise, the product may be damaged.
