Accounting for Elevation Changes
It is always preferred to have the QGateway located at the highest elevation possible to ensure maximum
communication range. Avoid locating the QGateway in low lying areas where hills will obstruct wireless
communications to the surrounding transformers. Accounting for this may increase the number of QGateways
needed depending on location availability.
Based on the above obstructions and distances and calculations, the following table can help record and scale
the required number of QGateways.

The above are rules of thumb and Qualitrol does not guarantee adequate performance of the wireless
connection based on these alone. Communications performance must be confirmed at the time of installation.
