Ericsson KRC 118 18/6 R2A RU22 2160 Radio Unit

The Ericsson KRC 118 18/6 R2A RU22 2160 is a telecommunications radio unit designed for integration into Ericsson base station systems used in mobile communication networks. This module functions as a radio transceiver responsible for transmitting and receiving radio frequency (RF) signals between the baseband processing equipment and mobile devices within the cellular network infrastructure. By converting digital baseband signals into RF signals and processing incoming wireless transmissions, the radio unit enables reliable wireless connectivity and efficient network operation.The RU22 configuration indicates that the module is designed to operate within frequency bands around 2200 MHz, which are commonly associated with cellular communication technologies such as UMTS and related radio access standards. The R2A designation refers to a specific hardware revision of the module, reflecting a particular production or design version optimized for stability and performance within Ericsson radio access network deployments.

Engineered for continuous operation in demanding telecom environments, the unit is built with durable electronic components and protective shielding that ensure consistent RF performance and resistance to environmental factors such as temperature variation, vibration, and electromagnetic interference. Its modular design allows straightforward installation and replacement within Ericsson base station cabinets or outdoor radio assemblies. The KRC series radio units are widely deployed by telecommunications operators to maintain network coverage, improve signal quality, and support stable wireless communication services across large-scale mobile infrastructure networks.
