ORU-4402

O-RAN compliant radio unit, 4T4R 5G Sub-6 20 Watt High Power radio.

Overview

The ORU-4402 5G O-RU is an O-RAN–compliant radio unit designed for 5G Sub-6 transmission, reception, and baseband processing, delivering a total output power of up to 20 W.

It supports the n77, n78, n79, n48, and n41 frequency bands, enabling reliable outdoor 5G NR Sub-6 coverage. The ORU-4402 features a 4T4R architecture, with 5 W output power per channel.

The unit connects to an O-DU or FHGW through an O-RAN 7.2 split eCPRI interface with Low-PHY. Featuring external antennas and IP67 protection, the ORU-4402 ensures reliability and durability in demanding outdoor environments.
