Moxa has announced its proprietary concurrent dual-radio technology for zero wireless packet loss in industrial WLAN applications. Designed with two independent RF modules to transmit duplicate packets via two distinct channels can eliminate packet loss when wireless interference occurs. Moxa’s AWK-5222 and AWK-6222 series industrial wireless AP/bridge/client devices feature concurrent dual-radio technology to achieve zero packet loss transmissions to provide safe and reliable communication for latency-sensitive applications.
Concurrent dual-radio technology
Wireless interference can interrupt data transmission and cause packet loss when transmitting with single-RF devices. To reduce packet loss, many advanced wireless technologies provide dual-RF devices with mechanisms to detect interference and automatically switch bands to restore communication. However, this type of redundancy has limitations and can still experience packet loss when switching between channels. Moxa’s concurrent dual-radio technology is designed to transmit duplicate packets simultaneously on two different bands (2,4 and 5 GHz). When interference interrupts packet transmission on one band, concurrent transmission via the other band eliminates packet loss to ensure maximum data throughput. For safety-critical applications with zero latency tolerance, Moxa’s concurrent dual-radio transmission with interference immunity is what operators need to ensure real-time performance.
The AWK-5222 access point has successfully passed the conformity test for SafetyNET p and has been certified by Safety Network International e.V to provide proven redundant wireless link technology for real-time Ethernet connectivity. Safety Network International e.V is impressed by Moxa’s concurrent dual-radio transmission, which has two independent RF modules to deliver redundant packets across different frequencies to prevent interference. If interference disrupts one of the two frequencies, the other frequency will continue to transmit data between the redundant AP and redundant client devices to deliver highly reliable network communication for safety-critical applications.
AWK-6222 and AWK-5222 features include:
• IEEE 802.11a/b/g compliant.
• Dual-RF design: 2,4 and 5 GHz RF bands.
• Supports 100 ms redundant roaming.
• Certified for SafetyNET p (AWK-5222 only).
• Rugged IP68-rated metal housing (AWK-6222 only).
• -40 to 75°C operating temperature range.
