Why cellular technology?
Cellular technology is a preferred choice in the IoT industry due to its global geographic coverage and seamless mobility support for connected devices. Industry analysis reveals that cellular IoT connections surpassed 4 billion by the end of 2024, representing approximately 22% of global IoT connections. The cellular IoT market is projected to grow from 7.63 十億 2025 到 21.66 十億 2030. The cellular IoT market is growing at 23.21% CAGR (2025–2030), driven by smart cities and Industry 4.0 adoption.While cellular networks greatly enhance device mobility, 這 differences among specific technologies (like LTE-M, LTE Cat.1, 和窄頻物聯網) mean that each excels in particular scenarios. Choosing the right one depends on project needs, balancing coverage, 電源效率, and data requirements.

Development of Cellular Technology
How Does Cellular Work?
The coverage area is divided into small regions called “細胞,” each served by a cell tower or base station. These cells ensure efficient frequency reuse and reduce interference.
Cellular devices communicate with the nearest cell tower using radio waves. The cell tower acts as a relay, connecting the device to the broader cellular network.
As the device moves, it switches between cell towers seamlessly (handover) to maintain uninterrupted connectivity.
The cell tower connects to the core network, which routes calls, messages, and data between devices (or users) and external networks like the internet.
