Moxa releases AWK-3131A Wireless Bridge

Wednesday, Jul 29, 2015

Moxa releases AWK-3131A Wireless Bridge with AeroLink Protection that automatically restores communications within 300ms of connection failure to help industrial wireless networks avoid interruptions.

AWK-3131A supports IEEE 802.11n technology with a maximum net data rate of 300 Mbps, plus AeroLink Protection redundancy to prevent a single point of failure from bringing down an entire network.

With AeroLink Protection, a network has two or more protected wireless client nodes connected to a single access point. One serves as the active node, while the others are passive backup nodes. If the active node stops sending or receiving data for any reason, AeroLink Protection completely restores the communication link within 300ms (milliseconds) by bringing backup nodes online.

Due to overcrowding on the 2.4 GHz frequency band and the introduction of 802.11ac, many industrial networks have already begun migrating to 5 GHz. The AWK-3131A can operate on either the 2.4 or 5 GHz bands and is backwards-compatible with existing 802.11a/b/g applications to future-proof wireless investments.

Seamless roaming offered by the AWK-3131A's Turbo Roaming technology reduces handover time to the millisecond level and provide the benefits of seamless transmission and control. To avoid packet loss, the AWK-3131A actively searches for APs with a stronger signal without waiting for a complete disconnection. Turbo Roaming is especially useful in the control and monitoring of mobile vehicles such as unmanned AGVs and shuttles commonly implemented in factory automation.

Power and radio frequency disturbances are the two most common causes of wireless communications failure in industrial computing applications. The AWK-3131A is designed with integrated dual isolation protection to mitigate both. First, Integrated RF Isolation provides 500-V insulation protection and level 4 ESD protection without loss of the RF signal. Next, Integrated Power Isolation provides 500-V insulation protection and stabilizes system voltage.

The AWK-3131A is compliant with industrial standards and approvals covering operating temperature, power input voltage, surge, ESD, and vibration to assure performance in harsh industrial environments such as oil refineries, water treatment centers and offshore platforms.
