of a building to provide coverage to outdoor spaces in front of the building, a directional antenna
can be used to direct the coverage away from the building.

High Mounting Omni-Directional Antenna Scenario (AP-ANT-80 vs. AP-ANT-90)
The AP-ANT-80 shows greater horizontal range due to its higher gain (8 dBi vs. 3 dBi) antenna, but in
this very high mounting situation, the AP-ANT-90 may be a better choice for ground level coverage
because the direction of maximum gain is directed downward toward the ground. This situation could
potentially be improved if a lower mounting elevation was available for the AP-ANT-80, ideally about
5 m above Ground.
