Chapter 1 Overview

AP1542I Internal Omni Antenna

The AP1542I model has in internal semi-omnidirectional antenna. The AP1542I access point
802.11b/g/n radio is used primarily for local access and its 802.11a/n/ac radio for client or wireless
backhaul in the mesh mode.
The 2.4 GHz b/g/n radio operates in 2.4 GHz ISM band. It has two transmitters with a maximum total
output power of 27 dBm for 802.11b/g/n operation. Output power is configurable for 8 levels in 3 dB
steps. It has two receivers which enable maximum-ratio combining (MRC).
The 5 GHz a/n radio operates in the UNII-1 band (5.15-5.25 GHz), 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 27 dBm depending on the regulatory domain. Tx
power settings will change depending on the regulatory domain. Output power is configurable in 3 dB
steps. It has two receivers which enable maximum-ratio combining (MRC).
The AP1542I model access point is equipped with the following integrated antennas:
