New Wireless AP/Bridge/Client Features AeroLink Protection™ for Maximum
Wireless Network Availability
AeroLink Protection on the new
AWK-3131A automatically restores communications within 300ms of connection
failure to help industrial wireless networks avoid interruptions
Aug. 11, 2015 + + + In industrial networking applications, such
as communications between offshore oil platforms or train-to-ground
communications, a reliable wireless bridge is essential to minimize system
downtime and maximize availability. Moxa's new AWK-3131A wireless
AP/bridge/client delivers exceptionally fast, ultra reliable wireless
performance in industrial settings by supporting 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.
"AeroLink
Protection constantly monitors each device's status. If the active node is
disabled by a local power failure or hardware fault, the backup nodes will
automatically take over to keep the data moving," said Sarun Kub, Product
Marketing Manager Industrial Wireless at Moxa.
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. Engineered for
flexible deployment, 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 the 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. For more information
