Ericsson KRD901059/1 Air 5121 massive MIMO active antenna unit for 5G mid-band deployments.

The Ericsson KRD901059/1 is an Air 5121 advanced antenna system, part of Ericsson’s Antenna Integrated Radio portfolio. This massive MIMO active antenna unit combines radio and antenna functionality into a single integrated unit, designed for 5G New Radio (NR) mid-band spectrum deployments. The Air 5121 utilises advanced beamforming technology to deliver high-capacity mobile broadband coverage.

The Air 5121 is deployed in macro cell networks as part of Ericsson Radio System, supporting mobile network operators in their 5G rollout strategies. It is designed for outdoor tower or rooftop mounting and integrates seamlessly with Ericsson baseband units to provide a complete radio access network solution.

This product represents Ericsson’s current-generation 5G radio technology, actively deployed by operators worldwide for enhanced mobile broadband (eMBB) services. The compact, integrated design reduces site complexity and installation time compared to traditional passive antenna plus remote radio unit configurations.
