Related communication protocols for 4G IoT networks (LPWAN NB-IoT and LTE-M) and 5G IoT networks (5G NR - URLLC) were described and a survey of two selected chipsets for 4G networks (Nordic Semiconductor nRF9160) and 5G networks (Quectel RM520N) and their development modules and kits was made. -One of the development kits (nRF9160 DK) was then used for practical demonstration of an IoT device with LPWAN connectivity on an example of a combined burglary and fire alarm system with 4 sensors, transferring data to a remote cloud server via MQTT protocol. This demo allowed to establish a firmware development base for 4G IoT devices based on nRF9160 System-in-Package and get familiarized with the software development kit by Nordic Semiconductor with Zephyr RTOS support. -Since there seem to be issues with a delivery of the appropriate 5G development kit by Quectel, being ordered for several months already, it would be advisable to focus the follow-up bachelor thesis only to 4G communication kits with nRF9160 System-in-Package and to further explore extensive firmware possibilities of this system for reliable and secure industrial IoT communication, specifically: - -\begin{itemize} - \item Firmware upgrades via FOTA (firmware over the air) - \item Implementation of ARM TrustZone technology for firmware protection against unauthorized changes - \item ARM CryptoCell solution for high-performance cryptography -\end{itemize} - -Experimental parameters of IoT communication (power consumption, lattency, reliability, effective range in complicated urban environment) shall also be verified, comparatively for NB-IoT and LTE-M protocols. +%One of the development kits (nRF9160 DK) was then used for practical demonstration of an IoT device with LPWAN connectivity on an example of a combined burglary and fire alarm system with 4 sensors, transferring data to a remote cloud server via MQTT protocol.
