Radiation Pattern
Because the antennas focus gains in front of the AP, signal strength in the front is stronger. Therefore it is preferable to
install the AP towards the area where wireless coverage is most required.
When mount the AP on a wall or ceiling, install the AP towards where you stand to avoid backward coverage.
It is preferable to install the AP in a way that maximizes coverage.
When install the AP indoors, it is better to mount it on the ceiling rather than on the wall because the AP
provides greater coverage when it is installed on the ceiling.
Figure 1-3 and Figure 1-4 show the preferred wall-mount and ceiling-mount orientations of the AP operating in the 2.4
GHz and 5 GHz bands, respectively.
