472797A Nokia Nokia Flexi Multiradio BTS Base Station Module

The Nokia 472797A is a Flexi Baseband Controller (FBBC) module designed for Nokia’s Flexi Multiradio Base Station platform. This baseband processing unit handles digital signal processing, channel coding, and interfaces between the radio frequency units and the core network transport layer.

The FBBC module is a core component within Nokia’s Flexi BTS architecture, supporting mobile network deployments across 2G, 3G, and LTE technologies. It provides the computational power required for baseband processing and manages connectivity to multiple remote radio heads or integrated radio modules.

This module represents Nokia’s Flexi platform generation of mobile infrastructure equipment. While newer Single RAN and AirScale platforms have since been introduced, Flexi equipment remains widely deployed in operational networks globally and continues to be supported for maintenance and capacity expansion purposes.
