Cisco Aironet 1552 Series for Hazardous Locations Installation Guide
Chapter 1 Overview
Hardware Features
The 5 GHz 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 22 dBm for the UNII-2 and UNII-2 Extended/ETSI bands. The total maximum output
power for the upper UNII-3 band is 28 dBm. Output power is configurable for 5 power levels in 3 dB
steps. The three receivers enables maximum-ratio combining (MRC).
Antenna Configurations
The 1552H, 1552SA/1552SD, and 1552WU models must always be operated with all the external
antennas attached or the antenna connectors sealed with plugs. Figure 1-7, Figure 1-8, and Figure 1-9
show the antenna port locations.
