As the core aggregation node of the eLTE-IoT solution, the eSE620X veLTE-IoT provides terminal management,access authentication and authorization of terminals and AirNode devices,network protocol processing, forwarding data from terminals and system operation and maintenance (O&M).To facilitate the interconnection with multiple industrial applications or platforms, the eSE6201 eLTE-IoT provides protocols commonly used in the IoT industry, including IP forwarding and Message Queue Telemetry Transport (MQTT). Therefore, it can be directly connected to the third-party applications or platforms that comply with those protocols. The eSE6201 eLTE-IoT also provides open infrastructure interfaces, management interfaces, and data interfaces, through which customers, integrators, and software developers can connect to third-party applications or platforms with a few simple steps of customization.
