Industrial Wireless IEEE 802.11 Solutions
AWK-4121 Series
Industrial IEEE 802.11a/b/g IP68 wireless AP/bridge/client
The AWK-4121 outdoor wireless AP/bridge/client is the ideal outdoor 
wireless solution for industrial applications that are hard to wire, 
too expensive to wire, or use mobile equipment that connect to a 
TCP/IP network. The AWK-4121’s dust-tight/weatherproof design is 
IP68-rated, allowing you to extend existing wired networks to outdoor 
locations and critical environments. The two redundant DC power 
inputs increase the reliability of the power supply and can be powered 
via PoE for easier deployment. The AWK-4121 is compliant with the 
essential sections of EN 50155, covering operating temperature, 
power input voltage, surge, ESD and vibration. With many hardened 
industrial-grade features, the AWK-4121 will provide stable and reliable 
wireless connectivity, even in harsh outdoor environments.
