Radio Operation and Antennas
AP 1532I
The AP 1532I uses an Integrated Low Profile Dual-Band 2.4/5 GHz Dipole Antenna Array. The
antenna contains an array of three dual-band dipole antennas. The three dipole antennas are contained
within this single radome, thereby greatly reducing the antennas visual footprint, and greatly reducing
the possibility of snagging the antenna on the cable bundle, the RF cable, or test cables. The antennas
operate over both 2.4 GHz and 5.25 – 5.85 GHz bands. Each of the three dipole antennas is a
dual-band antenna, covering both the 2.4 – 2.483 GHz band, and the 5.25 – 5.85 GHz bands. The
antenna have a peak gain of about 2 dBi at 2.4 GHz and 4 dBi at 5 GHz. The antenna unit is gray
weatherproof radome for outdoor operation.
The 1532I access point 802.11b/g/n radio is used primarily for local access and its 802.11a/n radio for
wireless backhaul in the Mesh.
The 2 GHz b/g/n radio operates in 2.4 GHz ISM band. It supports channels 1-11 in US, 1-13 in Europe,
and 1-13 in Japan. It has three transmitters with a maximum total output power of 29dBm for
802.11b/g/n operation. Output power is configurable to 5 levels. It has three receivers that enables
maximum-ratio combining (MRC).
The 5GHz a/n radio operates in the UNII-2 band (5.25 - 5.35 GHz), UNII-2 Extended/ETSI band (5.47
- 5.725 GHz), and the upper ISM band (5.725 - 5.850 GHz). It has two transmitters with a maximum
total output power of 29 dBm for UNII-2 and Extended/ETSI bands for the A-domain. The total
maximum output power for the upper ISM band is 28 dBm for A-domain. Tx power settings will
change depending on the regulatory domain. Output power is configurable for 5 power levels in 3 dB
steps. Its three receivers enables maximum-ratio combining (MRC).
The 1532I access point is equipped with three integrated dual-band antennas with 3 dBi gain at 2 GHz
and 5 dBi at 5 GHz.
Warning
In order to comply with radio frequency (RF) exposure limits, the antennas up to 8 dBi
gain for this product should be placed no less than 20 cm (8") from your body or nearby
persons. This distance shall be increased to 50 cm (20") with antennas that have gain
between 8 and 14 dBi.

Warning
Do not locate the antenna near overhead power lines or other electric light or power
circuits, or where it can come into contact with such circuits. When installing the
antenna, take extreme care not to come into contact with such circuits, because they
may cause serious injury or death. For proper installation and grounding of the antenna,
please refer to national and local codes (for example, U.S.:NFPA 70, National Electrical
Code, Article 810, Canada: Canadian Electrical Code, Section 54).
