꧁ Products Description ꧂
RRU2217 B20
RRU consists of the following stems:
* High speed interface unit
* signal processing unit
* power amplifier
* doubler
* expansion port
* Power module
* signal processing unit
* power amplifier
* doubler
* expansion port
* Power module
The RRU performs the following functions:
* Receives downlink baseband data from the BBU and sends uplink baseband data to this baseband unit.
* Receives an RF signal from the antenna system, down-converts the signal to an intermediate frequency (IF) signal, amplifies the IF signal, performs analog-to-digital conversion, and up-converts the RF signal to the transmit (TX) band.
* Multiplexing the receive (RX) and TX signal RF channels allows these signals to share the same antenna channel and filter the RX and TX signals.
* Available with built-in offset tee (BT). The built-in BT couples the RF signal and OOK signal and transmits them through TX/RX port A. The built-in BT is also a Tower Mount Amplifier (TMA).
* RRU can use AC/DC power supply module. In this case, this RRU is called a remote communication unit.

꧁ Information science ꧂
Definition of base station
A base station, that is, a public mobile communication base station, is a form of radio station. It refers to a radio transceiver station that transmits information with mobile phone terminals through a mobile communication switching center in a certain radio coverage area.
How the base station works
In order to achieve network access for mobile terminals, base stations are essential infrastructure. So what is the structure of a base station? The base station is mainly composed of an antenna system, a radio frequency unit (Remote Radio Unit, RRU), and a baseband processing unit (Base Band Unit, BBU).
●Antenna feeder system:
Responsible for the sending and receiving of signals.
●Radio frequency unit:
responsible for signal generation and extraction.
●Baseband processing unit: Responsible for information processing and processing.
