| Popis: | In this article, we evaluate the feasibility of the consumer eSIM solution for advanced smart products. Such smart products provide services and additional value already during their transport for different actors in the supply chain. The logistics hubs can invite the smart products to attach to their private networks and request tailored services from them. This requires seamless public-private network mobility that can be achieved with the consumer eSIM-based operator profile switching. We verify this approach in a laboratory demonstration with two operators having live cellular IoT networks and a smart product switching between the networks. We also measure the duration and device energy consumption of network switching when the active operator profile is switched locally at the device. Based on the results, the cell search dominates both the delay and energy consumption in network switching. With pre-loaded profiles, local eSIM operations minimize the service downtime and are preferred over the standard M2M eSIM, which requires OTA signaling. |
