Huawei NetEngine AR161W Fixed‑Interface Gigabit Enterprise Wi‑Fi Branch Router Full Product Description

1. Short Overview

Naming & Variant Breakdown

• AR161W: Base Wi‑Fi‑integrated model, 1×GE WAN, 4×GE multi‑purpose ports, built‑in 802.11b/g/n 2.4 GHz Wi‑Fi, AC power, no PoE, no cellular, no voice ports, no expansion slots.
• AR161: Wired‑only version without built‑in Wi‑Fi.
• AR161‑G‑L: Variant with built‑in LTE CAT4 cellular backup modem.
• AR161W‑S: Cost‑optimized channel‑oriented variant.

Difference vs AR150 series: AR161W provides full‑gigabit interfaces and higher service throughput; it is non‑modular without SIC expansion slots. It is commercial office‑grade device, non‑industrial. Operating temperature: ‑5 °C ~ +45 °C, no DIN‑rail mounting, no industrial DI/DO alarm terminals.
