E-Lins wifi DIO 5g router with sim card slot for IOT

A router is a device that connects various local area networks and wide area networks in the Internet. It will automatically select and set routes according to channel conditions, and send signals in the best path and in sequence. The router is the hub of the Internet, the "traffic cop". At present, routers have been widely used in all walks of life, and various products of different grades have become the main force for realizing the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet. The main difference between routing and switching is that switching occurs at layer 2 (the data link layer) of the OSI reference model, while routing occurs at layer 3, the network layer. This difference determines that routers and switches need to use different control information in the process of moving information, so the way they implement their functions is different.

The E-Lins Industrial IoT 5G routers with sim card slot are compact, ruggedized designed for mission-critical connectivity in the most challenging environments. It is qualified for M2M (Machine to Machine), IoT (Internet of Things) and In-Vehicle applications. With an extensive list of safety and hardening certifications, which is engineered to protect against extreme temperatures, humidity, shocks, vibrations, dust, reverse polarity, and transient voltage, which is widely used in more than twenty industrial fields, such as CCTV security surveillance, vehicle, Telemetry, vending machines, power control, AMR, traffic, oil field, weather forecast, environmental protection, street lamp control, post, bank and many other areas.
