15 40-MHz channel bonding in 2.4 GHz is not applicable. Therefore, the maximum data rate is 144 Mbps.
16 Composite power is the power when we have two Tx streams enabled in AP1552.
17 1552 has 3 dB better receiver sensitivity when compared to 1520 series APs.
Note
AP1552 has almost the same antenna gain with ClientLink (Beamforming) as compared to AP1522s.
There is no 20-MHz channel bonding available in the 2.4-GHz band to get the 40-MHz channel as we
only have 3 nonoverlapping channels. The maximum data rate that we can achieve in 2.4 GHz is 144
Mbps.
For the 5-GHz band, 1520s and 1552s have almost the same Tx power, but 1552s have approximately 4 dB
better Rx sensitivity because of the availability of MRC in 5 GHz (see
for the 5-GHz band in -A Domain, on page
