Huawei RRU3938

The Huawei RRU3938 is a high-performance Remote Radio Unit (RRU) designed for multi-standard LTE and 5G-ready mobile networks, providing exceptional coverage, capacity, and energy efficiency. Operating in Band 3 (1800 MHz), this unit supports advanced MIMO configurations and carrier aggregation, enabling operators to maximize spectrum utilization and improve user experience. The RRU3938 is part of Huawei’s SingleRAN solution, which allows simultaneous support for multiple wireless technologies—including GSM, UMTS, LTE, and NR (New Radio)—within a unified hardware platform.

The device features a compact, lightweight design with passive air cooling and a fully sealed IP65/IP66-rated enclosure, ensuring reliable operation in harsh outdoor environments. It offers high output power (2 × 80 W) and 4T4R capability, making it ideal for dense urban sites as well as wide-area coverage. The RRU3938 connects to Huawei Baseband Units (BBUs) via the CPRI optical interface, supporting flexible deployment in centralized or distributed RAN architectures. Its energy-efficient hardware and simplified installation help operators lower site power consumption and reduce total cost of ownership while preparing for 5G evolution through software upgrades.
