Ericsson Radio 2219 B1

The Ericsson Radio 2219 B1 is a highly efficient and compact remote radio unit (RRU) engineered for operation in the 2100 MHz frequency band (Band 1). It is part of the Ericsson Radio System portfolio and is designed to provide mobile operators with reliable, high-capacity performance while supporting smooth network evolution toward 5G. With 2T2R MIMO configuration and an impressive output power of up to 2 × 120 W, this unit ensures wide-area coverage, improved signal strength, and high data throughput. Supporting an air interface bandwidth of up to 60 MHz aggregated within Band 1, the radio enables advanced LTE features such as carrier aggregation and higher-order modulation.

Built for flexibility, the Radio 2219 B1 supports LTE (4G) and is backward compatible with WCDMA (3G), while also being fully 5G-ready, making it a forward-looking solution for operators preparing for next-generation networks. Compact in design and protected with IP65/IP66-rated housing, it withstands challenging outdoor conditions and allows installation on towers, poles, or walls near antennas, reducing feeder loss and increasing efficiency. With optical fronthaul interfaces (CPRI and eCPRI) supporting up to 10 Gbps throughput, it integrates seamlessly with Ericsson baseband units and supports centralized or cloud RAN architectures.

The radio operates with a –48 V DC power supply and features redundant power options for increased reliability. Its energy-efficient architecture helps reduce operating costs while maintaining robust performance under heavy traffic loads. With a strong combination of power, reliability, and future readiness, the Ericsson Radio 2219 B1 is ideal for expanding LTE capacity, improving coverage, and enabling a smooth transition to 5G services.
