Huawei 3200 Series Remote Radio Units eRRU3251 Frequency Band
RRU Functions:
The Remote Radio Unit (RRU) consists of the high-speed interface
unit, signal processing unit, power amplifier, duplexer,
extension ports, and power module.
The RRU performs the following functions:
* Receives downlink baseband data from the BBU and sends uplink
baseband data to the BBU.
* Receives RF signals from the antenna system, down-converts the
signals to intermediate frequency (IF) signals, amplifies the IF
signals, performs analog-to-digital conversion, and up-converts RF
signals to the transmit (TX) band.
* Multiplexes receive (RX) and TX signals on the RF channel so that
these signals can share the same antenna channel, and filters the
RX and TX signals.
* Provides a built-in Bias Tee (BT). The built-in BT couples RF
signals and OOK signals and transmits them through the TX/RX port
A. The built-in BT also supplies power to the tower mounted
amplifier (TMA).
* The RRU can work with the Monitoring Extension Box (MEB). The MEB
can transmit external RS-485 communication signals and dry node
monitoring signals into the RRU, implementing information
monitoring and reporting.
* When an RRU is equipped with an AC/DC power module, the RRU and the power module together are called an AC RRU.
