Gateways featuring Semtech’s LoRa® devices often reside in electrically harsh industrial environments. As the centerpiece for a LoRaWAN® network, these gateways need to operate in the field for many years. The longevity of the network requires that gateways be immune to a range of transient threats the equipment may encounter over its lifetime. As such, gateway data ports need to be safeguarded from overvoltage transient threats, including electrostatic discharge (ESD), electrical fast transients (EFT) and lightning surge.

It’s amazing actually.
