NetEngine AR502H is Huawei's next-generation edge computing-Internet of Things (EC-IoT) series gateway, which provides powerful edge computing capabilities, open software and hardware resources, and SDK (Software Development Kit), and can flexibly call computing, storage, and network resources. The AR502H supports container management and on-demand application deployment, and is suitable for a wide range of IoT applications, including intelligent integrated energy services (IES), smart pole sites, smart power distribution rooms, smart campuses and smart water conservation. In fact, Huawei AR502H series routers are specially designed for large-scale edge computing and IoT networking in harsh environments, and can cope with extreme temperatures, humidity, and electromagnetic interference. AR502H has rich IoT interfaces, supports IP-based power line communication (PLC) and on-demand APP deployment, and achieves modular structure and combination.
