3.1.2 GPS/Compass alignment
A GPS (Global Positioning System) can be used to align the unit by taking a waypoint at the AP. This will
allow you to get the proper bearing to the AP from the building the SU is on. Then by holding the GPS next
the SU you can turn the SU to the proper bearing. This can also be done with a compass if the bearing has
been defined by looking at a map. Or if the installer knows the general direction of the Access Point.
Note:
When purchasing a GPS make sure it has a digital compass, because if it doesn’t the GPS compass is not
accurate unless you are moving.
