IoT, short for the Internet of Things, is also known as the "Internet of Everything." It refers to a network of devices and sensors that communicate with each other and share data over the internet. With technological advancements like artificial intelligence, big data, and cloud computing, IoT has become increasingly prevalent. 

One of the significant characteristics of IoT is that devices and sensors are always connected, allowing them to gather, process, and analyze data automatically. For example, IoT enables the automatic control of household facilities such as lighting and temperature, promoting energy efficiency. Moreover, IoT technology integrated into automobiles enables features like autonomous driving. 

However, IoT comes with challenges such as interoperability between devices, security issues, and privacy concerns. Given its widespread adoption, ensuring appropriate and secure use is crucial. 

 

IoT Market Size 

According to the latest report of IDC, the IoT market continues rapidly to expand, with a market size of US$805.7 billion in 2023, showing a 10.6% increase over 2022. Investments in the IoT ecosystem are projected to exceed US$1 trillion by 2026, with a compound annual growth rate (CAGR) of 10.4% from 2023 to 2027. 

This significant growth can be attributed to the digitization of industries, often referred to as Industry 4.0, and increased usage in fields such as healthcare. While IoT initially focused on enhancing daily life convenience, it has evolved to offer even more services, contributing to the expansion of the market. 

 

Three Key Elements of IoT 

IoT comprises three essential elements that should be understood: 

Connectivity 

IoT devices require reliable and scalable methods of connecting to the internet or other networks. This can be achieved through various technologies, including Wi-Fi, cellular networks (3G, 4G, 5G), LPWAN technologies like LoRaWAN or NB-IoT, Bluetooth, Zigbee, or wired connections like Ethernet. The choice of connectivity depends on factors such as device location, power requirements, and data transmission needs. 

Data Security and Privacy 

IoT involves collecting and transmitting sensitive data, necessitating robust encryption, authentication, and access control mechanisms to protect devices and data. Security measures should be implemented at all levels of the IoT ecosystem, from device hardware and firmware to cloud servers and data storage. Compliance with privacy regulations and best practices is vital for safeguarding user data. 

Scalability and Interoperability 

IoT ecosystems often consist of devices from various manufacturers, running on diverse platforms and protocols. To ensure seamless communication and data exchange, IoT requires standards and protocols that facilitate interoperability. Scalability is also crucial to accommodate the growth of IoT networks as more devices are added. Standards organizations and industry alliances work to establish common protocols and frameworks to facilitate interoperability and scalability within the IoT ecosystem. 

 

Three Examples of Implementations in IoT 

Remote Control 

IoT allows for the remote control of various devices. This includes not only direct device manipulation but also the ability to control one device from another. For instance, smart lighting systems can be controlled from a smartphone, which can also control other devices like televisions or air conditioners. 

Remote Sensing 

IoT enables the detection of movement through devices or sensors. These sensors can detect physical movement, such as impacts or suspicious activity around areas like windows. By connecting sensors to the internet, users can monitor these situations even when away from home. 

Remote Monitoring 

IoT devices provide information about their status, allowing for real-time monitoring. For instance, machines equipped with IoT sensors can automatically notify users of any issues or malfunctions, enhancing efficiency and preventing downtime. 

 

Demand and Future Prospects of IoT 

As indicated in IDC's forecasts, the IoT market is poised for further expansion in recent years. IoT is increasingly finding applications in diverse domains, making it even more ubiquitous. While it is already a high-demand field, it is believed that the demand for IoT will surpass its current levels in the near future. 

Furthermore, akin to the trends seen in artificial intelligence (AI), the IoT market has seen a surge in the entry of numerous startups, many of which are making a significant global impact. For instance, Soracom, which originated in Japan, has been deploying a cloud-based IoT platform and has expanded its market presence not only in Asia but also in the United States and Europe, establishing a robust foothold in the IoT connectivity arena. These IoT startups, including Soracom, are increasingly gaining recognition, with some even being featured alongside major carriers like Vodafone in Gartner's Magic Quadrant for 2023. 

Additionally, in the job market, there is a growing demand for engineers well-versed in both cloud and connectivity technologies to meet the expanding IoT market's needs. In other words, the demand for engineers capable of handling IoT is on the rise, encompassing roles not only in device development but also in areas related to cloud infrastructure and applications.
