The AWK-3131 3-in-1 industrial wireless AP/bridge/client meets the 
growing need for faster data transmission speeds by supporting IEEE 
802.11n technology with a net data rate of up to 300 Mbps. The AWK-
3131 is compliant with the essential sections of EN 50155, 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-3131 can be powered via PoE to make 
deployment easier. The AWK-3131 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.

•  High-speed wireless connectivity with up to 300 Mbps data rate
•  MIMO technology to improve the capability of transmitting and 

receiving multiple data streams

•  Increased channel width with channel bonding technology

•  Industrial-grade QoS and VLAN for efficient data traffic 

management

•  Integrated DI/DO for on-site monitoring and warnings
•  Signal strength LEDs for easy deployment and antenna alignment
