C-IoT (Cellular Internet of things) is a term that is used to describe a number of cellular-based technologies supporting IoT. C-IoT covers EC-GSM-IoT (Extended Coverage - GSM- IoT), LTE-M ( Long term evolution- Machines), and NB-IoT (Narrowband IoT). Cellular IoT technologies will drive the digitization of society by delivering M2M (Machine to Machine), and machine-to-person communications on a massive scale. Connected, Intelligent software-defined products enable new opportunities for both consumers and industries by boosting connectivity. The new IoT landscape has IoT rollout, enterprise IT and business processes, IoT platforms, and connectivity. Connectivity is the foundation for the Internet of things, and the type of access required depends upon the nature of the application. 3GPP technologies like GSM, WCDMA, LTE, and 5G NR operate primarily on the licensed spectrum and have high-quality mobile voice and data services.
Narrow-band IoT and LTE for Machine type communications (LTE-M) are optimized access technologies for low power wide area (LPWA) applications. LTE-M extends LTE with features of extended device battery life, enhanced coverage, and support for low complexity device category series. NB-IoT is a standalone radio access technology that is based on the fundamentals of LTE technology and can enable extreme coverage and extended battery life for ultra-low complexity devices. IoT applications are to categorize them according to coverage needs and performance requirements such as data, speed, and latency demands, etc.
