HIVEAP 320 PRODUCT OVERVIEW
Antennas
The HiveAP 320 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 toroidal
(donut-shaped) pattern around each antenna (see Figure 4 on page 30).
The three 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.
Figure 2 Antennas and 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.
