Description
Ericsson AIR 6449 KRD901203/11 B43
The Ericsson AIR 6449 KRD901203/11 B43 (Antenna Integrated Radio) is a high-performance, TDD (Time Division Duplex) Massive MIMO unit designed for 5G New Radio (NR) networks operating in the mid-band frequency range of 3.6 GHz – 3.8 GHz.
Description and Key Features for Ericsson AIR 6449 KRD901203/11 B43
The Ericsson AIR 6449 KRD901203/11 B43 is a crucial component in Ericsson’s 5G portfolio, classified as an Advanced Antenna System (AAS). It integrates the radio electronics and a sophisticated antenna array into a single unit, enabling powerful digital beamforming and Massive MIMO capabilities.
- Massive MIMO & Beamforming: The unit supports up to 64 Transmit and 64 Receive (64T64R) branches, which allows for advanced beamforming in both vertical and horizontal planes. This technology increases cell capacity significantly and improves coverage.
- High Performance: The B43 model supports a maximum output power of up to 280 W. It can handle multiple carriers in mixed mode operation (e.g., up to 4 carriers for B43).
- Rugged Design: Designed for outdoor installation on walls, poles, or masts, the unit is housed in a robust, passively cooled enclosure with an IP65 rating for protection against dust and water jets.
- Interfaces: It uses high-speed eCPRI optical interfaces (up to 25.8 Gbps per port) to connect to the RAN processor/baseband unit.
