RRU the Remote Radio Unit is a radio transceiver capable of handling multiple of 8 mobile subscribers calls. This is called RRU as this unit is generally installed in towers and are controlled by a controller placed inside a closed shelter on the ground nearby the tower. The connection between the RRU and the controller is generally optical. The RRU and the controller forms the BTS or Base Transceiver Station that is widely used in cellular communication.
It is a Digital TransReceiving Unit
The BB2F card in Nokia BTS is a Baseband Processing Unit that handles the digital signal processing tasks for the base station. It controls the radio resources, manages call setups, and processes the data before it is transmitted or received by the radio units. It plays a crucial role in managing the communication between the core network and the radio access network.
The function of FXC Card, is to provide E1 conectivity to BTS. It have four E1 port and it can be used to connect other bts as "cascade". Where do you hear about this card? Do you work for a telecom company? Please, let me know in order to help you.
Transmission between BTS and BSC.FIFA card contain only TNC male connector.
Hello! A BOIA card (or BCF card) is the Base Station Control Function in a BTS. The BCF is like the BTS's brain, controling, for example, TRx's hopping.
RBS 3102 is Ericsson BTS for 3G. 4 Way diversity for this BTS means that two BTSs are crossconnected to each other and they both have two Rx branches, so in total there are 4 Rx branches on the antenna.

This is bcoz we need -48V for Gsm BTS, -48 DC is used to control Fluctuation So the main function of this is 1) To convert AC to DC 2) To control overloading
3g BTS is greater than 2g bts. and it is with new technologies.
Between 2 and 5 RRU's are supported by one DUG. The actual number varies based on the configuration of the DUG and the intended application for the system.
· - Provides physical ports between the BTS and the BSC for interaction. · - Provides the ports for communication with the radio filter. · -Provides the USB port for downloading the BTS software · -Provides operation management channels. · · -Provides centralized management on the entire BTS system, such as OM and signaling processing · -Provides the reference clock for the entire system. - Provides for management of Microwave, Optical Fiber and other communication signalling process. - Details of Function of BBU is here telecombase.blogspot.com/2015/11/bbu-base-band-unit-in-telecom.html
