Ericsson Radio 4415 B3

The Ericsson Radio 4415 B3 is a high-capacity, energy-efficient remote radio unit (RRU) within the Ericsson Radio System portfolio, purpose-built for operation in the 1800 MHz spectrum (Band 3). As one of the most widely deployed LTE bands worldwide, Band 3 is critical for mobile operators seeking to expand coverage and increase capacity, and the Radio 4415 B3 delivers both with excellent efficiency. Compact and robust, it is designed for outdoor deployment and provides reliable performance in urban, suburban, and rural environments.

The radio supports LTE (4G) and WCDMA (3G) services while being fully 5G-ready, enabling smooth technology evolution and protecting operator investment. With its 4T4R MIMO configuration and high output power per port, the Radio 4415 B3 significantly enhances spectral efficiency, increases throughput, and improves service quality even under high-traffic conditions. It also supports advanced LTE features such as carrier aggregation and higher-order modulation, making it a flexible solution for capacity expansion. Connectivity to Ericsson baseband units is provided through high-speed CPRI and eCPRI optical interfaces, each capable of transporting up to 10 Gbps, ensuring seamless fronthaul integration into centralized or cloud-RAN architectures. Its compact form factor allows installation close to antennas on towers, poles, or walls, reducing feeder loss and maximizing transmission efficiency.
