1. Introduction
The AirEther BR108 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 AirEther BR108 is a wireless building-to-building bridge solution. The AirEther
BR108 provides the data rate up to 108 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 AirEther BR108 provides the point to point and point to
multi-point connection.
One of the AirEther BR108 advanced feature is over the data rate section. The bridge
has two data rate modes, one is the IEEE 802.11a, and another is the IEEE802.11a turbo.
About the bridge under the IEEE 802.11a mode, it supports the data rate from 6 Mbps to 54
Mbps. Under the IEEE802.11a turbo mode, it supports the data rate from 12 Mbps to 108
Mbps in turbo mode. The supported frequency channel for the IEEE802.11a or the
IEEE802.11a turbo are across from 5.15 to 5.85 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 either 17 dBi or 23
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. AirEther BR108 Hardware FEATURE
2.1 Product Feature
 Temperature — The wireless bridge is tested for normal operation in temperatures
from -30°C to 70°C.
 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, and 14Km at the Turbo mode.
 Rain — The wireless bridge is weatherproofed against rain and prolonged heavy rain
has no significant effect on the radio signal. It is highly recommended to use sealing
tape around the RF connector for prolonged operation. If moisture enters the
connector, it may cause degradation in performance or even a complete failure of the
link.
