Ericsson AIR 6419 KRD901208/11 B42
The Ericsson AIR 6419 KRD901208/11 B42 is an advanced Antenna Integrated Radio (AIR) unit designed for 5G Massive MIMO deployments. It integrates a powerful 64-transmitter, 64-receiver radio into a single enclosure, leveraging digital beamforming for superior coverage and capacity in mid-band urban networks.
Technical Description for Ericsson AIR 6419 KRD901208/11 B42
The Ericsson AIR 6419 KRD901208/11 B42 functions as a crucial component of a 5G base station (gNodeB). It is installed outdoors near the antenna location to minimize cable losses. The unit uses a 64T64R architecture with a 192-element antenna array to electronically steer radio beams (beamforming) in real-time, focusing signal energy precisely where users are located.
The radio is powered by the latest generation of Ericsson Silicon, which enhances processing capabilities while maximizing energy efficiency. It uses passive cooling (no internal fans) for increased reliability and an IP65-rated rugged enclosure to withstand harsh weather conditions. It connects to the baseband unit (Digital Unit) via high-speed optical eCPRI links.
