2.1.2.2 Airlink Chassis Unit (ACU)
The Airlink Chassis Unit provides the baseband airlink processing for up to 8
RadioFrame Units, providing a coverage area up to 250,000 square feet. The
ACU is the interface between the RFUs and the Network Chassis Unit, and
provides power, signals, and timing to the RFUs.
