Comprehensive Safety Approvals for Outdoor LoRaWAN Network Gateway Structures: Going Beyond IP Assessments

Comprehensive Safety Approvals for Outdoor LoRaWAN Network Gateway Structures: Going Beyond IP Assessments

Building a LoRaWAN network comes with several essential considerations. First, opt for a high-quality, reliable LoRaWAN gateway that's proven by an outdoor equipment certificate, ensuring a secure connection. Gateways should be resilient, capable of sending real-time alerts, and compatible with multiple devices, sensors, routers, and different types of applications. A safety-certified product should also feature a robust antenna for harsh environmental conditions. To strengthen its connectivity, the network server should be able to link with multiple gateways.

Another crucial factor to consider is processing gain – the ratio of the code sequence chip rate to the bit rate of the data signal. Higher processing gains will ensure smooth signal recovery even in low-signal environments, offering advantages over Wi-Fi and Bluetooth. For secure outdoor deployments, a LoRaWAN gateway must provide end-to-end encryption and support various applications.

Ensuring equipment safety is essential. While terms such as "IP67" and other ingress protection ratings may be commonly used, it's important to understand that they signify only a partial protective barrier against dust and water. The term "outdoor" implies that the product has undergone rigorous evaluations and tests culminating in a special outdoor equipment certificate. Certain suppliers opt for easier, less expensive methods, marketing their products as simply "IP rated." However, only outdoor equipment with This special certification can provide the assurance needed for reliable, safe, and secure outdoor deployment.

Outdoor equipment certification typically comprises the Ingress Protection Rating (IP rating), ensuring limitations on dust and water entry, and adherence to the international safety standard IEC 60950-22, known as Information Technology Equipment Safety – Equipment to be Installed Outdoors. The international safety standard is recognized in the USA, Canada, and Europe and outlines design requirements, critical evaluations, and test methods to ensure safe and reliable equipment for deployment outdoors.

Outdoor equipment must meet specific specifications to endure at least 10 years of field operation without failures or degradation. Compliance with the LoRaWAN standard guarantees compatibility with any required sensors or devices. The frequency should be at least 30GHz to seamlessly connect with necessary sensors, eliminating network disruptions. The device should be double-certified – with IEC 60950-22 certification and other ingress protection rating confirmations, it ensures connectivity to Wi-Fi networks and maintains consistent connections.

Reliability and UV protection are essential to prevent the degradation of exposed polymer materials over time. IEC 60950-22 includes requisites for UV resistance and related tests. Compliance with UL 746C ratings provides an acceptable level of UV resistance in outdoor use. Gasket life and endurance in an outdoor environment are crucial for enclosure ingress protection. IEC 60950-22 specifies gasket aging and strength tests to ensure enclosure gaskets maintain their tensile strength and compression resiliency properties.

Corrosion protection is critical, especially in coastal or polluted urban environments, where corrosion occurs at higher rates. IEC 60950-22 includes requirements and tests for ensuring enclosure integrity and electrical contact safety under these circumstances. Enclosure ingress tests are generally performed in accordance with IEC 60529 or UL 50E, depending on local requirements.

Since outdoor environments may expose equipment to additional heat loads due to direct sunlight, it's essential to account for this during design, ensuring reliability at temperatures up to 10°C above the maximum specified ambient temperature. Surge protection is vital for outdoor deployments, particularly in regions prone to lightning. Consult standards such as IEC 62305-1 or NFPA 780 for guidance.

In conclusion, when building a reliable and secure LoRaWAN network, focus on selecting a trustworthy manufacturer with extensive knowledge of LoRa Alliance technology standards, spreading factors, and network reliability. Always choose a reliable gateway to safely manage network communication and ensure it's compatible with all connected sensors. Solar loading, surge protection, plant and animal protection, and marking robustness are essential additional considerations.
