1. Introduction
The ALink-5801a is designed for the outdoor environment. It will function under the strict
weather as the following passages you see. About the further protection, the bridge and
Power over Ethernet adapter are built with the lightning protector. This advanced innovation is
to help you to increase from the productivity, cost-effective, mobile Internet access, to other
sections.
The ALink-5801a is a wireless building-to-building bridge solution. The ALink-5801a
provides the data rate up to 54 Mbps that is best suited for enterprises, campus or off-site
locations that require LAN or Internet access without the availability of wired networks to extend
the network coverage. The ALink-5801a provides the point to point and point to multi-point
connection.
One of the ALink-5801a advanced feature is over the data rate section. The bridge has
one data rate mode, the one is the IEEE 802.11a. About the bridge under the IEEE 802.11a
mode, it supports the data rate from 6 Mbps to 54 Mbps. The supported frequency channel for
the IEEE802.11a is across from 5.725 to 5.850 GHz.
Another advanced design is the security setting. We all know the security is the major issue
over the wireless communication. We offer the two modes on the security setting, one is
“Shared Key”, and the other is “Unique Key”. It is really easy for you to secure your
communication through this thoughtful feature.
About the field installation, it is easy for you to install the device outside field. The
following paragraphs remind you what you need to notice during the installation form the site
survey, antenna installation, to the ODU installation. We also offer you the evaluated max
distance as your reference under the IEEE802.11a and the Antenna gain is 12 dBi .
During the appendix section, we offer you some terminologies explanation and how to do
the simple troubleshooting when you encounter the difficult over the wireless connection.

2.3 Product Feature
 Temperature — The wireless bridge is tested for normal operation in temperatures
from -33°C to 55°C. Operating in temperatures outside of this range may cause the
unit to fail.
 Wind Velocity — The wireless bridge can operate in winds up to 90 MPH and survive
higher wind speeds up to 125 MPH. You must consider the known maximum wind
velocity and direction at the site and be sure that any supporting structure, such as a
pole, mast, or tower, is built to withstand this force.
 Lightning — The wireless bridge includes its own built-in lightning protection.
However, you should make sure that the unit, any supporting structure, and cables are
all properly grounded. Additional protection using lightning rods, lightning arrestors,
or surge suppressors may also be employed.
 Range —The wireless bridge has been refined and optimized for long range
application, up to 28Km under the Basic data mode.
 Rain — The wireless bridge is weatherproofed against rain and prolonged heavy rain
has no significant effect on the radio signal. You may need to use the sealing tape
around the Ethernet port connector for extra protection. If moisture enters the
connector, it may cause degradation in performance or even a complete failure of the
link.
