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.
Figure 4 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).
