Mounting The Ap320 - Aerohive Networks AP121 Hardware Reference Manual

OUNTING THE
Antennas
Antennas are an integral part of the AP320. The AP320 has six internal single-band antennas. Three of the
antennas operate in the 2.4-GHz band (IEEE 802.11b/g/n) and have a 2-dBi gain. The other three antennas
operate in the 5-GHz band (IEEE 802.11a/n) and have a 3-dBi gain. All antennas are omnidirectional,
providing fairly equal coverage in all directions in a cardioid (heart-shaped) pattern around each antenna
(see Figure 6 on page 72).
The three 2.4-GHz antennas link to radio 1, and the three 5-GHz antennas link to radio 2. Conceptually, the
relationship of antennas and radios is shown in Figure 2.

the two internal radios
The wifi0 interface links to radio 1 (frequency range = 2.4 GHz for IEEE 802.11b/g), and the wifi1 interface links
to radio 2 (frequency range = 5 GHz for IEEE 802.11a). These interface-to-radio relationships are permanent.
Although hive members automatically adjust their signal strength according to their environments, you can
resize the area of coverage by increasing or decreasing the signal strength manually by entering the
interface { wifi0 | wifi1 } radio power <number> command, where <number> can be from 1 to
20 and represents a value in dBm.

OUNTING THE
Using the mounting plate and track clips, you can mount the AP320 to the tracks of a dropped ceiling grid.
Using just the mounting plate, you can mount the AP320 to any surface that supports its weight (2 lb., 0.9 kg).
You can also mount the AP320 on a table using the four rubber feet that ship with the product. Peel
the rubber feet off the adhesive sheet and press them on each underside corner of the device.
