Huawei AAU5726 02312KQG 32T32R Dual-Band FDD Massive MIMO 5G Radio

The Huawei AAU5726 02312KQG is a high-capacity, dual-band FDD Massive MIMO Active Antenna Unit. It is specifically designed to bridge the gap between 4G and 5G by providing advanced 3D beamforming on the widely used 1.8GHz (Band 3 1800MHz) and 2.1GHz (Band 1 2100MHz) frequencies.

Technical Description & Specifications for Huawei AAU5726

Unlike older hybrid models (like the AAU3911), the Huawei AAU5726 is a dedicated Active Massive MIMO unit with an integrated radio and antenna array. It focuses on maximizing spectral efficiency through high-order MIMO.

Interface & Wiring Map for Huawei AAU5726

The Huawei AAU5726 is an “Active-Only” unit. It does not have RF ports for external jumpers. All “wiring” is for power, data, and management:

1. CPRI0 / CPRI1 (Optical): Connects to the BBU (typically a UBBPe or UBBPg board) via high-speed fiber optics (SFP+ 25G).
2. PWR (Power): Connects to a -48V DC power source using a waterproof quick-lock connector.
3. AUX (AISG): Used for external sensors or maintenance terminals; it does not connect to other antennas.

Key Features for Huawei AAU5726

• 3D Beamforming: Adjusts beams in both horizontal and vertical planes to follow users, significantly improving SINR and cell-edge throughput.
• FDD Massive MIMO: Brings Massive MIMO benefits (traditionally for TDD) to FDD bands, doubling or tripling capacity compared to 4T4R.
• 5G NR Evolution: Supports simultaneous LTE FDD and 5G NR FDD carriers, allowing for a software-defined transition to 5G.
