May 13, 2013 - Moxa introduced concurrent dual-radio technology in AWK-5222 and AWK-6222 industrial wireless access points that ensures zero packet loss in industrial WLAN applications, eliminating problems such as video frame skips, screen freezes and dropouts in safety-critical and real-time wireless applications. The "Zero Wireless Packet Loss" solution uses two independent RF modules to simultaneously transmit duplicate packets on two different bands (2.4 GHz and/or 5 GHz RF bands) to ensure that at least one of the packets reaches the receiver. Simultaneous dual-radio transmissions also increase the throughput by reducing the number of resend requests. Other features of the AWK-5222 and AWK-6222 include:
- IEEE 802.11a/b/g compliant
- Supports 100 ms redundant roaming
- Compliant with essential sections of EN 50155
- Rugged IP68-rated metal housing (AWK-6222 only)
- -40 to 75°C operating temperature range.
"The unpredictability of radio interference has long been a deterring factor for industrial operators wanting to deploy wireless connectivity," explained Ariana Drivdahl, Product Manager for Moxa. "While self-healing and dual-band devices having been developed to somewhat mitigate its impact, signal recovery and renegotiation in band switch-over can still result in unacceptable packet loss. Concurrent dual-radio transmission architecture is the first and only technology that completely bypasses all interference."
"Even when routine measures are taken to identify and eliminate environmental interference, wireless interference still remains a possibility and can compromise network reliability and system safety," said Drivdahl. "Moxa's concurrent dual-radio transmission with interference immunity is what operators need to ensure real-time performance with zero-data-loss communication."
