In critical industrial and outdoor wireless applications, the level of availability and reliability is extremely important. A redundant link guarantees that the entire network will always be in service.
Move Freely and Reliably over Wireless Networks
Moxa's new generation AWK-6222, which conforms to the IEEE 802.11a/b/g standards, can be configured as an access point, bridge, or client. This outdoor unit features dual independent RF modules with 2.4 or 5 GHz dual-band operation to enhance redundancy and frequency range, and creates the best possible topology. The AWK-6222's unique industrial blend of IP68 rated protection, wide operating temperature, and seamless roaming allows industrial users to achieve ultra-reliable and redundant wireless networks under challenging outdoor, mobile conditions.
Fully Redundant Wireless Networks

The traditional wireless infrastructure includes access points (AP) that connect many clients to a wired network. Since APs and clients are linked by a single-RF connection, if the RF link fails, the system and network behind the client will be disconnected. To get around this problem, the AWK-6222 comes with dual RF modules in a single WLAN device to enable two independent wireless connections using different frequencies to avoid interruptions in data transmission. To maximize wireless and wired network availability in a systemic way, the AWK-6222 incorporates dual Ethernet ports that support IEEE 802.1w RSTP or Moxa's Turbo Ring to form loop-free redundant paths over the wired side of the network.

Reliable Dual-band Wireless Connectivity
The AWK-6222 comes with dual RF channels that allow simultaneous operation of 2.4- and 5-GHz wireless networks to prevent transmission interferences. In addition, the detachable antenna design gives uses the unparalleled flexibility to match the antenna to their application-specific needs in complex RF environments. The user-friendly Moxa WLAN calculator helps you quickly select the best antenna for your application.  
Turbo Roaming for Seamless Mobility
For moving objects, users need an uninterrupted network connection when a client transmits data and moves from one access point to another. The AWK-6222 supports Moxa's proprietary Turbo Roaming with millisecond-level handover time, which ensures seamless mobility while roaming a wireless network.
Rugged Rating for Outdoor Use
The robust construction allows the AWK-6222 to provide a new perspective for wireless signal transmission in tough outdoor environments. The AWK-6222 is housed in an IP68 metal casing with M12 connectors for total protection against dust, water, vibration, and other environmental effects. With an extended temperature range of -40 up to 75°C and dual redundant power inputs, operational reliability is assured. Power distribution in outdoor and remote areas has never been easier. The AWK-6222 is compliant with IEEE 802.3af PoE to add installation flexibility. In addition, this rugged unit provides long-distance transmission of 10 kilometers or more, and the industrially hardened features let you set up a rock-solid WLAN, or extend existing wired networks to outdoor locations.
