14 OMEGA Installation, Operation, and Maintenance Manual
Finding a Suitable Location
Because OMEGA is a wireless solution, it is not possible to predict
how it will perform in all given environments. However, observing
the following guidelines will help optimize performance in your
environments and applications.
c
Selecting a location for installing OMEGA.
−
The location must provide adequate cellular coverage and
signal strength (preferably –90 dBm or better). It is quite
common that in certain locations such as basements, below-
street-level locations, and between hills and rural areas, the
receive signal might be inadequate for cellular
communications. In these cases, use an optional YAGI or
elevated-feed antenna to improve reception (see Section 5
for more information). You can use the OMEGA
configuration application to evaluate the cellular telephone’s
receive signal strength (see Section 4).
−
Be sure there is sufficient space for OMEGA to connect to
the endpoint device. This distance should not exceed 500
feet.
−
Make sure there is sufficient space to work. The space
should be dry, away from overhead water pipes and free of
airborne contaminants.
−
The location should place OMEGA within six feet of a
properly grounded AC outlet.
c
Remote antenna installation.
If you will be using a remotely located antenna, locate the
antenna 10 feet above ground level and no more than 50 feet
from the OMEGA unit (the shorter the distance, the better).
Section 5 provides details about the external antenna
installation process.
c
Avoid radio-frequency interference.
Consider the environment’s radio-frequency characteristics,
including construction materials and the presence of windows
and ducting. The radio-frequency field pattern may be
influenced by nearby metal objects such as appliances,
equipment, and metal wall framing.
