The AWK-4131A IP68 outdoor industrial AP/bridge/client meets the 
growing need for faster data transmission speeds by supporting 
802.11n technology and allowing 2X2 MIMO communication with a 
net data rate of up to 300 Mbps. The AWK-4131A is compliant with 
industrial standards and approvals covering operating temperature, 
power input voltage, surge, ESD, and vibration. The two redundant DC 
power inputs increase the reliability of the power supply, and the AWK-
4131A can be powered via PoE to make deployment easier. The AWK-
4131A 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 
investments in wireless networks.

•  802.11a/b/g/n compliant AP/bridge/client for flexible deployment
•  Software optimized for long distance (LoS, 1 km) wireless 

communication with external high-gain antenna (available on 5 GHz)

•  Supports 60 clients connected concurrently
•  DFS channel support allows a wider range of 5 GHz channel 

selection to avoid existing wireless infrastructure and interference

•  Seamless roaming with Client-based Turbo Roaming for < 150 ms 

roaming recovery time between APs (Client mode)

•  Supports AeroLink Protection for creating a redundant wireless link 

(< 300 ms recovery time) between AP and clients (Client mode)

•  Integrated antenna and power isolation designed to provide 500 V 

insulation protection against external electrical interference

•  IP68 rated metal casing for complete ingress protection for any 

outdoor weather

•  -40 to 75°C wide operating temperature provided for smooth 

wireless communication in harsh environments

  2.412 to 2.462 GHz (11 channels) 
  5.180 to 5.240 GHz (4 channels) 
  5.260 to 5.320 GHz (4 channels)* 
  5.500 to 5.700 GHz (8 channels, excluding 5.600 to 5.640 GHz)* 
  5.745 to 5.825 GHz (5 channels) 
EU: 
  2.412 to 2.472 GHz (13 channels) 
  5.180 to 5.240 GHz (4 channels)*  
  5.260 to 5.320 GHz (4 channels) 
  5.500 to 5.700 GHz (11 channels)* 
JP:

  5.260 to 5.320 GHz (4 channels)* 
  5.500 to 5.700 GHz (11 channels)*

*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.
