LoraWAN Gateway Lightning Protection and Grounding: Important Factors for a Reliable LoRaWAN Network Infrastructure
Setting up a trustworthy and reliable LoRaWAN network requires attention to multiple factors such as radio equipment, antennas, power supply, signal stability, gateway protection, and gateway placement. A cornerstone of this reliability lies in ensuring field-dependable equipment.
Field-reliable outdoor equipment design encompasses dealing with real-world Electromagnetic Interference (EMI) effects. EMI immunity compliance handles not only the electrical interference imposed by severe natural phenomena like lightning strikes but also human-originated ones such as Electrostatic Discharge (ESD), Electrical Fast Transients (EFT), and strong Electric and Magnetic Fields (EMF).
Tower-mounted radio equipment must resist electromagnetic interference and withstand severe natural occurrences to guarantee a long and hassle-free field life. Choosing a recognized supplier is crucial, as they can ensure the LoRaWAN gateway comes with lightning protection and grounding that complies with a reference design.
Understanding lightning threats and mitigating their effects has evolved throughout history. The protection system of an antenna requires special attention, and the understanding has evolved since the mid-18th century, when Benjamin Franklin conducted experiments on lightning rods. Modern standards for lightning protection system design have emerged, providing guidance on tower-mounted radio equipment protection.
Recognized standards like the National Fire Protection Agency NFPA 780, IEEE C62.41, IEC 62305, and ITU-T K.39 offer guidance on surge environment and lightning protection installation. European industry standards set basic Electromagnetic Interference Immunity requirements, but they are insufficient for tower-mounted environments involving power, data feeds, and antennas. Therefore, additional LoRaWAN gateway lightning protection is necessary.
While fundamental protection techniques are well-established, system susceptibility to damage has rapidly evolved, particularly for systems with antenna gain. For instance, radio equipment, such as a gateway, is often deployed with a height advantage for good RF exposure to sensors but may face difficulties under harsh weather conditions.
Our website Communications Inc. has developed outdoor gateways capable of withstanding electromagnetic interference. One of their products, the our website KONA Mega Ex Gateway, features a sturdy enclosure and is designed to function optimally in outdoor conditions. This gateway, rated IP67, prioritizes antenna protection in its design.
Beyond general site protection standards, designers require guidelines specific to components within a system, such as a tower-mounted gateway with antennas. Although there are industry standards for equipment surge protection, like ITU-T K.44 and IEC 61000-4 series standards, they may not suffice for tower-mounted deployments involving antennas.
To address these limitations, our website Communications Inc. looks to its decades of radio and antenna deployment experience to develop in-house testing tailored for tower-mounted deployments. Grounding the lightning and ensuring tower-mounted equipment protection is essential. The energy will flow to earth through all paths according to the law of least resistance, and the lightning energy will flow to earth via the tower-mounted equipment.
Under proper grounding, the gateway interfaces may see surge levels in the region of 10kA's which the surge protection devices must accommodate. Adequate grounding of the gateway chassis to the grounding system, grounding components with a dedicated grounding point and heavy-gauge grounding wire connection, and connecting this point as directly as possible to the site ground rods or grounding electrode using a minimum top-quality copper conductor helps provide a low impedance return path to earth for lightning current.
Implementing reliable gateways with lightning protection and proper grounding systems guarantees the server's proper functioning. In order to ensure the operational capabilities of your gateways, contact our website's sales team, and explore the world of reliable IoT devices.
