Features and Benefits 

  • IEEE 802.11a/b/g compliant
  • Dual-radio design for 2.4 GHz and/or 5 GHz bands
  • Supports client-based Turbo Roaming and redundant roaming
  • Rugged IP68-rated housing and -40 to 75°C operating temperature


The AWK-6222 outdoor wireless AP/bridge/client avoids interruptions in WLAN transmissions with its dual 2.4/5 GHz RF modules, which allow two independent wireless connections over different frequencies. To maximize wireless and wired network availability, the AWK-6222 can incorporate Ethernet redundancy using RSTP, and power redundancy using dual DC power inputs and PoE. In addition, the AWK-6222 is housed in an IP68 metal casing with M12 connectors for total protection against dust, water, vibration, and other environmental effects. This rugged unit supports seamless roaming to achieve ultra-reliable and redundant wireless networks under challenging outdoor, mobile conditions. These industrially hardened features let you set up a rock-solid WLAN to ensure that your entire network will always be in service. The AWK-6222 is compliant with the industrial standards and approvals, covering operating temperature, power input voltage, surge, ESD and vibration.

Redundancy to Increase System Reliability

White Paper:

Critical Elements of Industrial-Grade Wireless Devices


Industrial operators using commercial-grade wireless devices for mission-critical wireless applications may be getting satisfactory wireless network service, but frequent maintenance and system downtime can add up to a high total cost of ownership. In this paper, we reveal many harmful effects commonly found in industrial environments that can quickly disable a commercial-grade wireless device, and discuss the types of protection an industrial-grade wireless device should provide to ensure continuous wireless network communication...more



Concurrent Dual-Radio Transmission for Zero Wireless Packet Loss  Download


The unpredictability of radio interference has long been a deterring factor for industrial operators wanting to deploy wireless connectivity for mission-critical applications. Many self-healing and dual-band technologies have been developed to mitigate the impact of interference. However, signal recovery and renegotiation can still result in packet loss and is unacceptable for latency-intolerant applications. Zero-packet-loss wireless communication can be achieved, using concurrent dual-radio transmission, to provide highly reliable wireless connectivity for safety-critical applications, with benefits such as optimized data throughput, interference immunity, and latency-free transmissions....more
