AT&T announced that it’s working with Giesecke+Devrient Mobile Security (G+D), which is collaborating with Altair Semiconductor, to integrate a SIM into the modem chipset for deployment across licensed Low-Power Wide-Area (LPWA) cellular networks. The integrated SIM is designed to securely embed SIM functionality into the chipset, processor and other module components, an all-in-one approach that will enable modules to power smaller, less costly and more energy-efficient IoT devices, said AT&T.
Although traditional SIMs will still be in use for years to come, AT&T said it expects the integrated SIM to make it easier for large-scale global deployments of low-cost asset trackers, smart sensors and more over LPWA networks designed for the IoT. The solution integrates G+D’s SIM solution with Altair’s ALT1250 chipset and AT&T’s nationwide US LTE-M network. AT&T added that it expects to make the integrated SIM commercially available by the first half of 2019.
