Network Interface
1.1 Function
The RRU3606 is developed by Huawei according to the TIA/EIA standards. In a
CDMA2000 1X network, the RRU3606 and the BBU3900 forms a DBS which serves a
cell or multiple logical sectors.
The functions of the RRU3606 are:
Receiving RF signals by using an antenna, down-converting the received RF
signals to the intermediate frequency signals, implementing amplification, analog
digit conversion, digital down conversion, matched filtering, and digital automatic
gain control (DAGC) on the intermediate frequency signals, and sending the
processed intermediate frequency signals to the BBU3900
Receiving downlink baseband data from an upper-level BBU3900, forwarding the
data of the cascaded RRU3606, implementing shaping filtering, analog digit
conversion on downlink spreading signals, and up-converting RF signals to the
transmit frequency band
Providing multiplexing and filtering of signals transmitted and received on the RF
channel
The RRU3606 connects to the BBU3900 through an optical interface (the CPRI
interface) and communicates with an MS through the Um interface.
