The most industrial cellular router will have an I/O option, which enables users to handle some alarm tasks. It should also support numerous types of tunnel options for data security such as IPsec, OpenVPN, L2TP, PPTP, GRE, and even DMVPN. Besides, a cellular router also provides a robust firewall so that it can handle packet-level traffic inspection, reconciling incoming traffic with outgoing requests.

A cellular router offers features such as Ethernet, Wi-Fi, serial ports, VPN security, dynamic routing, and link back up, providing reliable connectivity and business continuity solutions. In some industrial IoT applications, cellular modems help to transport data from industrial serial devices to data control servers, allowing businesses to benefit from real-time data monitoring, management, and control.Ī cellular router usually is a highly intelligent device, Every cellular router actually contains a cellular modem. A cellular modem is not intelligent and not programmable, it simply sends traffic from one point to the other point, it usually doesn’t provide too much data protection, and it won’t have a firewall function.

They allow Internet connectivity via serial port to PLCs, Meters, Vending Machines, so sometimes it could be called a serial-to-cellular converter. The cellular modem provides connectivity across a broad range of M2M and IoT applications. This article will focus on what is cellular modems, what is cellular router and what is cellular gateway, and when to choose which. It could be very helpful when you try to select cellular communication hardware for industrial cellular applications. When it comes to the difference between cellular modems, cellular routers, and cellular gateways, people could be very confused about it, so it is necessary to clarify the difference, which will help you to clearly understand the device functionality of modems, routers, and gateways.
