Active Antenna Units
Active antenna units and massive MIMO radios
Manufacturers: Ericsson, Huawei, Nokia
An active antenna unit integrates the radio and the antenna array into one assembly, which is what makes massive MIMO practical on a tower that cannot carry separate radios and panels. These units are heavier and draw more power than the radios they replace, so tower loading and site power are usually the binding constraints rather than the specification. This category covers Huawei AAU, Ericsson AIR and Nokia AirScale MAA units. Band, TX/RX order, total output power and the fronthaul interface are the fields to confirm before ordering.
