The 1552 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 two transmitters with a maximum total output power of 25dBm 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 26 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 1552 models C and I access points are equipped with three integrated dual-band antennas, with 
2 dBi gain at 2.4 GHz and 4 dBi gain at 5 GHz. The antenna works in cable strand mount and low 
profile applications.
