The Nokia FXFC 472679A is part of the Nokia Flexi Multiradio BTS system, designed primarily for building high- wireless base stations. This module is widely used in the deployment of GSM/EDGE, 3G, and 4G LTE networks, offering multi-technology co capabilities, making it suitable for operators to enhance network capacity in areas with limited spectrum resources. It is typically used in conjunction with the baseband unit (BBU) and remote radio (RRH) to form a complete wireless access link.

NOKIA FXED RRU is a remote radio unit (Remote Radio Unit, referred to as RRU) produced by Nokia. RRU is a key device in wireless communication networks and is usually used in conjunction with the baseband processing unit (BBU) to amplify and transmit wireless signals in wireless base stations.

The Nokia FXEB 472501A is a key RF module in the Nokia Flexi base station, designed for the 180MHz GSM band, featuring high power (90W class), integrated cooling, and widely used in base station equipment for telecommunications networks.

The Nokia FXDD 47564A is a high-performance radio frequency remote unit designed by Nokia for 4G LTE networks. Through modular design and high-power output, it meets the wireless needs of base station systems.

The Nokia FXDB 472573A.102 is a part of the Nokia Flexi multi-mode base station platform widely used in the radio access network (RAN) of 2G/3G/4G mobile networks. This module belongs to the critical components of the remote radio unitRRU) or base station transceiver (BTS), responsible for the transmission and reception of radio frequency signals. This device is a 900MHz frequency band RF from the Flexi RF Module series manufactured by Nokia, with the model number FXDB 472573A.102, mainly used in wireless base station, supporting three-carrier 90W output. This module is commonly seen in distributed base station architectures, used as a remote radio unit (RRU), which can connected to the baseband processing unit (BBU) via fiber, achieving flexible deployment. It is applied in wireless base station infrastructure, LTE/4G network deployment.
