IP design for SIMs for industrial IoT: Using fixed/dynamic global IPs and private IPs

In industrial IoT, not only "which communication SIM to use" but also "which IP address format to choose" greatly affects security, stable operation, and maintainability. In this article, we will explain the differences between fixed global IP, dynamic global IP, and private IP, and how to choose the appropriate one for industrial IoT.

What is remote provisioning?

As IIoT devices become more widespread, there is an increasing demand for greater flexibility and efficiency in communications. One technology that is gaining attention in this context is "remote provisioning." Remote provisioning is a technology that remotely and securely rewrites the communication profile of a SIM card or eSIM. This eliminates the need for physical SIM replacement, and allows changes in telecommunications providers and configuration updates to be made without the need to visit the site. This is an innovative system that significantly improves operational efficiency, especially for devices like IIoT devices that are installed in remote locations or that are in the hands of end users.

Why choose cellular over Wi-Fi?

When considering services that use communications, Wi-Fi may be the first option you consider. It's fast, inexpensive, and has excellent connectivity with devices such as tablets and gateways, making it a very attractive option. However, there are also cases where people choose cellular communications over Wi-Fi. In this article, we'll explore the reasons for this from a technical and operational perspective.
