Networking and communications equipment is not always installed in clean, climate-controlled environments. Many devices operate outdoors, in industrial facilities, on building exteriors, at entry points, or in other locations where rain, dust, and other environmental factors can affect performance over time.
That is why data sheets often include environmental ratings and certification codes such as IP, NEMA, IEC, MIL-STD, UV, and ETSI. These standards can be difficult to interpret at first glance, but they provide important clues about where a device can be safely deployed and what conditions it is designed to withstand.
In this article, we demystify the weather and environmental protection standards manufacturers use so you can more confidently choose the right equipment for harsh environment deployments.
