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.

cSelecting 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.

cRemote 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.

cAvoid 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.
