What is NB-IoT and NTN?
Narrowband Internet of Things (NB-IoT) is a low-power wide-area (LPWA) technology specifically designed to connect a wide range of devices across various industries to the internet. It enables devices to transmit small amounts of data over long distances while consuming minimal power, making it ideal for applications like smart metering, environmental monitoring, and asset tracking. On the other hand, Non-Terrestrial Networks (NTN) refer to communication infrastructures that operate outside of traditional terrestrial networks, including satellite and airborne systems. NTNs aim to extend connectivity to remote and inaccessible areas, ensuring that even the most isolated devices can communicate effectively.
Together, NB-IoT and NTN play a crucial role in expanding IoT capabilities, enabling seamless and efficient data transmission in urban, rural, and challenging environments. They represent the future of connectivity, promising a more integrated world with efficient communication across diverse applications.
