Preparing for the Installation 
 
ACU is the interface between the RFUs and the Network Chassis Unit, and 
provides power, signals, and timing to the RFUs. The ACU is 7” high x 19” wide 
x 13” deep, powered by 120VAC, and rack mounted. All connections are CAT 5 
(RJ45) except for power.
  
RadioFrame Unit or RFU 
The RadioFrame Unit serves as the access interface between signals received 
from mobile terminals, via a standard air interface, and the airlink processing 
performed in the ACU. The RFU is approximately 8” high x 13.5” wide x 5” deep 
and mounts conveniently on a wall, or on or above the ceiling to serve a coverage 
area up to 32,000 square feet (100’ cell radius). The RFU connects to the ACU via 
a single CAT 5 connection, receiving its power, signals, and timing from the 
ACU. Each RFU holds up to 7 RadioBlades.

RadioBlades 
Each RadioBlade provides a single RF channel transceiver supporting one of 
several voice and wireless data standards, including GSM, CDMA, iDEN, 
802.11b (WLAN), and many others. Each RadioBlade is approximately  
4” high x 1/2” wide x 3” deep and inserts into a slot in the RFU. Each RadioBlade 
contains an onboard omni antenna and provides a coverage area of 
approximately 32,000 square feet (nominal 100’ radius cell).
