The Moxa AWK-1137C Series is a compact, rugged industrial wireless client purpose-built for demanding mobile and fixed wireless applications in industrial environments. Designed to bridge both Ethernet and serial devices to Wi-Fi networks, this device excels in factory automation, AGV systems, port logistics, and any scenario where reliable wireless connectivity is non-negotiable.
Compliant with IEEE 802.11a/b/g/n and carrying certifications including UL, CE, and FCC, the AWK-1137C is a well-rounded solution for organizations seeking industrial-grade wireless performance without compromising on ease of deployment.
Quick Overview:
In short, the AWK-1137C is an industrial Wi-Fi 4 wireless client that serves as an external Wi-Fi gateway for your wired Ethernet or serial edge devices. It does not create its own Wi-Fi network; instead, it connects to your existing network infrastructure. Because of its dedicated, client-only functionality, the AWK-1137C is a highly cost-effective alternative to universal AP/bridge/client devices.
Key Advantages & Specialty
If you are wondering what separates this unit from a standard commercial Wi-Fi client, it comes down to industrial reliability. Let’s dive deeper into the specific features of Moxa’s AWK-1137C to highlight what makes it stand out:
Network Address Translation (NAT) Support
Anti-Vibration & Industrial Ruggedness
Managing IP addresses across a sprawling factory floor can quickly become a headache. The AWK-1137C solves this by supporting one-to-many NAT (Network Address Translation), allowing multiple Ethernet and serial devices connected to its LAN ports to share a single wireless IP address. This dramatically simplifies machine network integration, reduces IP address management overhead, and enables straightforward plug-and-play deployments for machines and PLCs without the need for complex network reconfiguration.
Industrial environments are rarely gentle on hardware. Tested with reference to IEC 60068-2-6, the AWK-1137C is engineered to withstand the constant vibrations common on manufacturing floors, rail vehicles, and mobile machinery. Its metal housing provides IP30 protection, while the integrated antenna and power isolation deliver 500V of insulation against electrical interference—a critical safeguard in high-noise industrial settings.
Furthermore, the optional wide-temperature models offer an operating range of -40°C to 75°C, making the device perfectly suited for outdoor installations, cold storage facilities, and environments subject to extreme thermal cycling.
Millisecond-Level Turbo Roaming
Compact & DIN-Rail Ready Design
In mobile applications, a dropped connection often means a stopped machine. To combat this, the AWK-1137C delivers client-based Turbo Roaming with a recovery time of under 150 ms, enabling seamless handoffs between access points. This is achieved through optimized 3-channel scanning and is particularly effective when operating at 100 Kbps traffic loads over interference-free 20 MHz RF channels with WPA2-PSK security.
Space inside control panels is always at a premium. At just 77.1 x 115.5 x 26 mm and weighing 470g, the AWK-1137C is one of the most compact industrial wireless clients available. Its slim profile supports standard DIN-rail mounting right out of the box, with optional wall-mounting kits also available. This makes it incredibly easy to integrate into existing control cabinets or panel boxes without requiring major space reallocations.

Real-World Applications
Because of its specialized feature set, the AWK-1137C truly shines in the following environments:
- Manufacturing & Factory Automation: Ideal for connecting robotic arms, conveyor systems, and PLCs to the factory network wirelessly, especially in areas where running physical cables is impractical or hazardous.
- Railway & Rolling Stock: Perfectly suited for mounting inside train cars or on track-side equipment where constant vibration would easily destroy an ordinary commercial Wi-Fi device.
- Oil, Gas & Utilities: Excellent for the remote monitoring of equipment in electrically noisy environments, keeping data secure and protected via its 500V power isolation.
- Automotive Assembly Lines: Frequently used to connect tools and sensors along moving assembly lines where flexible, wireless setups are heavily preferred over fixed cabling.
AWK-1137C Review: Summary
The Moxa AWK-1137C Series is a compelling choice for engineers and system integrators working in challenging industrial wireless environments. Its combination of sub-150ms Turbo Roaming, NAT-enabled network simplification, vibration resistance, and dual-band 2×2 MIMO technology directly addresses the core demands of modern industrial deployments.
