Internet of Things (IoT)
What is the Internet of Things
IoT (Internet of Things) is a technology that provides unprecedented new value and services by connecting a wide variety of physical devices to the Internet. Even before IoT, a technology called M2M (Machine to Machine) that communicates between devices within a closed network was widespread. IoT, on the other hand, connects all kinds of things such as industrial equipment, houses, automobiles, home appliances, and consumer goods to the Internet. It made it possible to provide services in a format.
Main use cases of IoT
By connecting things that were not previously digital devices to the Internet, we will be able to do three things. They are the “operation of things”, “data collection by things”, and “communication between things” through the Internet.
Manipulation of things
By utilizing IoT technology, we can operate everything from lighting equipment and home appliances in the home to operating medical equipment and industrial drones from anywhere as long as things are connected to the Internet. These operations are mainly performed through dedicated applications that run on PCs and smartphones. On the other hand, due to the time lag caused by communication and problems with the control performance of the device itself, there are still issues in the operation of delicate operations and operations that handle large amounts of data.
Data collection by things
IoT often comes with sensors. Images and videos for camera-type devices, environmental information (temperature, humidity, atmospheric pressure, illuminance) for factories, weight, shock, vibration for motion sensors, and location information for GPS-equipped devices. Various information of things can be collected, processed, analyzed, and visualized through the Internet. The amount of information that IoT detects is extremely large, and if it is converted into data and sent to the cloud, it may not be possible to process it. I have.
Communication between things
As mentioned above, communication between objects was prevalent in the M2M format within a limited network. On the other hand, IoT is expected to perform complex processing because the Internet is mediated in addition to that. Especially in the field of autonomous driving, the possibility of connecting traffic signals and roads to the Internet of Things (IoT) and connecting them to the Internet is being explored to prevent accidents.
