Radiation Pattern
The AP uses internal antennas. See the three kinds of radiation patterns in Figure 1-3 and Figure 1-4 . 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 ceiling or wall, install the AP towards where you stand to avoid backward coverage.
It is preferable to install the AP in a way that maximizes the 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 ceiling-mount and wall-mount orientations of the AP operating in the 2.4
GHz and 5 GHz bands, respectively.
