The Guardian wireless modem provides a high-speed data link suitable for a wide variety of applications requiring system security and diagnostic reporting. Designed for speed and efficiency, Guardian provides over-the-air data rates up to 19. Sensor data is uploaded to a cloud-based software platform that leverages machine learnin ors measure tri-axial vibration and surface temperature. Learn more about Nozomi Guardian Air, the first wireless security. Guardian Air is a wireless security sensor for operational technology (OT) and Internet of Things (IoT) environments. The MT3620 is the first Azure Sphere certified "microcontroller", a completely new class of connected SoC IoT d vice that features “end-to-end security”. User applications can target it's 500 MHz ARM Cortex-A7 core as well as two general purpose 200 MHz.
[pdf] Cold isn't the real threat: The glass strands rarely freeze, but moisture that seeps into connectors can freeze and cause damage. Optical fiber must be robust enough to cope with being run between communications masts for telecoms links, across freezing ground for television outside broadcasts, and alongside roads to carry video from traffic cameras. One specific problem is how the fibers and connectors cope with sub-zero. While the fibers themselves are protected by an acrylic layer, the connectors joining each fiber can be vulnerable in harsh environments. The actual glass or plastic inside the cable that transmits the data is not affected by cold temperatures. The wide application of fiber-to-the-home (FTTH) has promoted the rise of fiber optic fast connectors/cold connectors.

[pdf] This guide provides a practical, standards-based approach to selecting managed industrial Ethernet switches and designing robust OT networks. Industrial fiber optic Ethernet switches are designed to deliver stable, long-distance, and interference-resistant network connectivity in harsh industrial environments where copper Ethernet is limited by distance or electromagnetic noise. Unmanaged switches are the simplest active network. To overcome the barriers caused by different protocols, the International Electrotechnical Commission (IEC) developed IEC 61850, which provides a standard communication protocol for electrical substations and power grid automation.
