2 Introduction to the RRU3908
About This Chapter
The RRU is the outdoor remote radio unit.
The RRU3908 performs the following functions:
lReceives downlink baseband data from the BBU and transmits uplink baseband data to the
BBU for communication between the RRU and the BBU.
lReceives the RF signals from the antenna system, down-converts the RX signals to
Intermediate Frequency (IF) signals, perform amplification, and analog-to-digital (A/D)
conversion. The TX channel performs shape filtering of the downlink signals, digital-to-
analog(D/A) conversion, and up-conversion of RF signals to transmit band.
lMultiplexes RX and TX signals to enable these signals to share the same antenna path, and
filters RX and TX signals.
2.1 Physical Exterior
The RRU has a modular structure. The external ports of the RRU are located at the bottom and
in the cabling cavity of the RRU.
2.2 Panels of the RRU
The RRU module has a bottom panel, a cabling cavity panel, and an area attached with LEDs.
2.3 LEDs on the RRU
The six LEDs on the RRU are used to display the running status of the RRU.
