What Is an Internet of Things (IoT) Service?
IoT service stands for “Internet of Things.”
To give an example, the IoT is a state in which various information obtained by various sensors is accumulated, and for a certain purpose, a computer analyzes the data, and processes the results remotely through the Internet.
Therefore, an IoT service is an application system that uses IoT to achieve a certain goal or solve a problem. It is used in an extremely diverse range of equipment, including not only smartphones and PCs but also home appliances and various industrial applications, without being limited by industry or scale.
Uses of IoT Services
The most common use of IoT services is proposing system solutions to corporate problems. Companies with system construction capabilities often take on the entire system construction of IoT services, from various sensors and terminals to cloud systems and host servers.
The most popular use of IoT solutions is to improve the efficiency of on-site operations at manufacturing sites. The widespread use of Internet IT technology and high-speed communication systems such as 5G is making it possible to address areas that were difficult to address in the past, such as traffic system management, various disaster prevention measures, and remote medical systems.
Principles of IoT Services
There are three typical components used in the IoT: first, the cloud server that serves as the host; second, the gateway that connects the device to the host via communications; and third, the device that actually connects to the Internet. While some devices may be connected directly to the server, if the devices are spread over a large area, a gateway is a more efficient way to configure the system. These are controlled through communication via the Internet to run the application system to solve the intended problem.
The NB-IoT (Narrow Band-IoT) is a low-cost and low-power-consumption wireless communication technology that can be used for smart meters, crime prevention, disaster prevention, and other anomaly detection applications, although its communication speed is slow. It is expected to be used for anomaly detection in smart meters, crime prevention, disaster prevention, and other applications.
