ABSTRACT
Global System for Mobile Communication Association and mobile operators has addressed several initial deployment requirements of the Narrowband Internet of Things (NB-IoT) ecosystem. The NB-IoT ecosystem is projected to grow significantly and explodes in terms of number of NB-IoT devices, their services and applications. NB-IoT devices are expected to be deployed using the three modes of operation: inband, guardband, and standalone. Message Queue Telemetry Transport is suitable for NB-IoT devices that have small memory and processing power, are battery powered, or have scarce bandwidth. Smart parking for cars, vehicles, and motorcycles can now utilize NB-IoT devices with ultrasonic sensors for detecting the availability of a parking spot. NB-IoT devices are typically found in sensors and actuators. The applications rely on using NB-IoT combined with sensors or actuators to transmit a huge amount of structured and unstructured data that can be used for automation, decision-making, and analysis.
