KRC161881/1 Ericsson Ericsson Radio System Radio Remote Unit

The Ericsson KRC161881/1 is a Radio 4419 B7, a compact remote radio unit (RRU) designed for LTE network deployments operating on Band 7 (2600 MHz). The Radio 4419 series forms part of Ericsson’s Radio System portfolio, providing the radio frequency transmission and reception functions at the antenna site in distributed base station architectures.

This unit is deployed in mobile network infrastructure where the baseband processing is handled centrally by a baseband unit, with the Radio 4419 installed at or near the antenna location. Band 7 operates in the 2600 MHz frequency range, commonly used for urban capacity layers where high data throughput is required to serve dense subscriber populations.

The Radio 4419 series represents an established generation of Ericsson radio hardware that has been widely deployed in 4G/LTE networks globally. As operators continue network evolution programmes, refurbished units remain valuable for network maintenance, capacity expansion, and extending the service life of existing LTE infrastructure.
