4 Installing the Mounting Poles
First install the mounting poles, on which you will mount the outdoor transceivers.
Bear in mind the direction in which the transceivers will point.
Attention! The mounting pole must be mounted in a vertical position. Failure to do so may
result in improper alignment of the outdoor transceiver. If you need to tilt the transceiver
down to avoid self-interference in a cellular-style deployment, you should use an (optional)
tilt bracket.
Warning! The mounting pole must be grounded. See Section 7.
4.1 Performing a CPE Site Survey
This section explains how to select the best location for mounting the outdoor transceiver. The
steps you will perform are:
• Determine which Access Points you can communicate with.
• Determine the direction of available Access Points from the house or building.
• Select an Access Point with as unobstructed Line of Sight (LOS) as possible. WiMAX allows for
NLOS operation, but the clearer the LOS, the more reliable will be the link.
4.1.1 What You Need
• Compass (or protractor).
• Area map with an accurate direction legend showing magnetic north.
• Access Point locations – these should be provided by your service provider.
4.1.2 Selecting an Access Point
In order for your AB-MAX System to work correctly, the CPE needs to be pointed towards the
Access Point(s) recommended by your AB-MAX System provider.
1) Using the compass bearings you wrote down in the previous section, walk around your build-
ing to find a suitable path to mount your outdoor transceiver – see Figure 4-3.
If necessary, move to an upstairs window or rooftop location to better view the surrounding area for
possible blockages in the path. Also, be sure to consider seasonal changes. A location that is
unobstructed in the winter may be obstructed by foliage in the spring, summer, and autumn.
