Multiple Radio Operation
The 1552 access point supports simultaneous dual-radio operation using a 2.4-GHz 802.11b/g/n multiple
input/multiple output (MIMO) radio and a 5-GHz 802.11a/n MIMO radio. The 2.4 GHz radio supports
channels 1 to 11 in US, 1 to 13 in Europe, and 1 to 13 in Japan. It has two transmitters with a maximum
total output power of 25 dBm for 802.11b/g/n operation. Output power is configurable to 5 levels. It has
three receivers that enable maximum-ratio combining (MRC).
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), upper ISM band (5.725 – 5.850 GHz), and the Extended India Band (5.85 – 5.875 GHz). It
has two transmitters with a maximum total output power of 26 dBm for UNII-2 and Extended/ETSI
bands. The total maximum output power for the upper ISM band is 28 dBm. Output power is
configurable for 5 power levels in 3 dB steps. The three receivers enables maximum-ratio combining
(MRC).
