Abstract

 The exponential growth of the Internet of Things (IoT) has driven the demand for advanced communication networks capable of supporting massive connectivity, ultra-low latency, and high reliability. The advent of fifth-generation (5G) technology marks a transformative era in IoT infrastructure, bridging the gap between intelligent devices, cloud computing, and real-time data processing. This article explores the fundamental role of 5G in enabling next-generation IoT networks by analyzing its architecture, key performance indicators, and deployment models. It further discusses how features such as enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and massive Machine-Type Communication (mMTC) revolutionize smart applications in healthcare, manufacturing, transportation, and urban infrastructure. The integration of edge computing, artificial intelligence (AI), and network slicing enhances scalability and adaptability, making 5G-IoT ecosystems pivotal for Industry 4.0 and future digital transformation.
