Technical Description for Huawei RRU5251 02312KYA
The Huawei RRU5251 02312KYA is a multi-mode, multi-carrier unit that serves as the RF processing engine for Huawei’s distributed base stations (DBS3900/DBS5900).
- TDD Technology: Optimized for Time Division Duplexing, where uplink and downlink traffic share the same frequency band but are separated by time slots, making it highly efficient for asymmetric data traffic.
- 4T4R MIMO: Features 4-Transmit and 4-Receive channels. This 4×4 MIMO capability significantly increases spectral efficiency and peak data rates compared to traditional 2T2R units.
- Multi-Carrier Support: Designed to handle multiple carriers simultaneously, allowing operators to aggregate bandwidth within the 2300–2400 MHz spectrum to achieve gigabit-level throughput.
- High-Speed Fronthaul: Equipped with a 10G CPRI/eCPRI port, providing the high-speed optical link necessary for 5G fronthaul and low-latency communication with the Baseband Unit (BBU).
- Rugged Outdoor Design: Built for harsh environments with an IP65 rating and passive cooling, ensuring high reliability without moving parts.
