Description

📘 Product Description / Assembling Components

The Huawei AP661 (also known as Huawei eKitEngine AP661) is an advanced indoor tri‑band wireless access point engineered to support high user density and demanding applications over Wi‑Fi 6. It uses three separate radios — one 2.4 GHz (2×2 MIMO) and two 5 GHz (2×2 and 4×4 MIMO) — working simultaneously to balance load and maximise throughput.

Built‑in smart antennas dynamically adapt coverage direction and signal strength based on the environment and client distribution, improving signal stability and reducing interference for all connected devices.

The AP661 supports multiple deployment modes — Fit, Fat, and cloud management — so it can be managed centrally, as a standalone unit, or via cloud‑based controllers depending on the network design. It also includes a USB port for additional IoT expansions and BLE (Bluetooth Low Energy) support for location services.
