Features and Benefits

  •  IEEE 802.11a/b/g/n compliant client
  • Comprehensive interfaces with one serial port and two Ethernet LAN ports
  • Millisecond-level Client-based Turbo Roaming*
  • Easy setup and deployment with AeroMag
  • 2×2 MIMO future-proof technology
  • Easy network setup with Network Address Translation (NAT)
  • Integrated robust antenna and power isolation
  • Anti-vibration design
  • Compact size for your industrial applications

*The Turbo Roaming recovery time indicated herein is an average of test results documented, in optimized conditions, across APs configured with interference-free 20-MHz RF channels, WPA2-PSK security, and default Turbo Roaming parameters. The clients are configured with 3-channel roaming at 100 Kbps traffic load. Other conditions may also impact roaming performance. For more information about Turbo Roaming parameter settings, refer to the product manual.


The AWK-1137C is an ideal client solution for industrial wireless mobile applications. It enables WLAN connections for both Ethernet and serial devices, and is compliant with industrial standards and approvals covering operating temperature, power input voltage, surge, ESD, and vibration. The AWK-1137C can operate on either the 2.4 or 5 GHz bands, and is backwards-compatible with existing 802.11a/b/g deployments to future-proof your wireless investments. The Wireless add-on for the MXview network management utility visualizes the AWK’s invisible wireless connections to ensure wall-to-wall Wi-Fi connectivity.

** DFS (Dynamic Frequency Selection) channel support: In AP mode, when a radar signal is detected, the device will automatically switch to another channel.
However, according to regulations, after switching channels, a 60-second availability check period is required before starting the service.

*** Due to a limitation in the receiver sensitivity performance for channels 153 and 161, it is recommended to avoid using these channels in your critical applications.
