Bittium Cellular IoT Solution is a modular software solution that runs inside an operator approved certified modem module. This approach minimizes needs from the host hardware and offloads cloud processing and communication stack software from the host system.
The modular structure of the software enables straightforward portability to cellular modem modules, which supports the application software running inside the module. Modules with this support are available from Nordic, U-Blox, Quectel, Telit and others.
Modem module adaptation work contains mainly updating the modem hardware and firmware adaptation part of the software solution (Modem Manager Module). Our current solution is running on Nordic nRF9160 modem module with CAT-M1 and NB-IoT cellular connectivity.
Host communication module
Architectural adaptation layer to the host system. Enables isolated adaptation to the host system hardware and software minimizing the changes for the system.
Modem Manager Module
Modem activity orchestrator with actual modem hardware and firmware adaptation. Modem manager controls the actual modem, modem state, LTE recovery and governs the activities of the Host Communication Module and Cloud Client Module.
Cloud Client Module
Communication module to the cloud/edge. Cloud Client Module adapts the data, event, task, and control communication from the host system to the target cloud infrastructure and selected protocols. Cloud Client Module uses modem's trusted environment for the communication security.
