Zero wireless packet loss uses concurrent dual-radio signals for safer, more reliable communication in latency-sensitive applications.
Moxa, a developer of hardened networking, communication, and computing equipment, has introduced proprietary concurrent dual-radio technology that ensures zero wireless 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 unpredictability of radio interference has long been a deterring factor for industrial operators wanting to deploy wireless connectivity,” explained Moxa Product Manager Ariana Drivdahl. “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.”
Available in Moxa AWK-5222 and AWK-6222 series industrial wireless access points, the company’s new “Zero Wireless Packet Loss” solution uses two independent RF modules to simultaneously transmit duplicate packets on two different bands (2.4 GHz, or 5 GHz, or both RF bands) to ensure at least one packet reaches the receiver. Simultaneous dual-radio transmissions also increase the throughput by reducing the number of resend requests.
“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. “Operators need Moxa’s concurrent dual-radio transmission with interference immunity to ensure real-time performance with zero-data-loss communication.”
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.
