Cellular IoT
Cellular IoT refers to the use of cellular network technologies (such as LTE-M, NB-IoT, and 5G) to connect Internet of Things (IoT) devices over wide areas, enabling reliable, low-power, and long-range communication for applications like smart cities, asset tracking, and industrial monitoring. It leverages existing cellular infrastructure to provide secure, scalable connectivity without the need for dedicated gateways or complex setups. This technology is standardized by organizations like 3GPP and is widely adopted by telecom operators globally.
Developers should learn Cellular IoT when building IoT solutions that require wide-area coverage, mobility, or deployment in remote locations, as it offers advantages like low power consumption (e.g., for battery-operated sensors), built-in security, and seamless integration with cloud services. It is particularly useful for use cases such as environmental monitoring, smart agriculture, and connected vehicles, where traditional Wi-Fi or short-range protocols are insufficient. Learning it helps in designing cost-effective and scalable IoT systems that can leverage global cellular networks.
