Background: 5G technology will revolutionize wireless communications, emphasizing spectrum efficiency. Pervasive device connectivity requires unprecedented spectrum resources to allow flawless Internet of Things (IoT) communication. Thus, dynamic spectrum sharing (DSS) is essential for 5G and IoT cohabitation without spectral congestion. Objective: This study examines how DSS improves 5G network speed and efficiency, especially in an IoT-dominated context. The main goals are strategies and methods to maximize spectrum sharing among 5G and IoT devices for resilient, scalable, and uninterrupted connectivity. Methods: Using simulation and testing, this study assesses 5G DSS algorithms and models for latency, throughput, and reliability. The current study compares conventional spectrum allocation and dynamic sharing strategies in various IoT applications. Results: 5G networks with DSS have improved spectrum usage and performance. Optimized algorithms reduce latency and increase throughput even in IoT-heavy situations. Conclusion: DSS is vital to strengthening 5G networks for IoT applications. DSS supports and expands IoT ecosystems by reducing spectrum scarcity and improving network performance, laying the groundwork for the 5G era's rush of connected devices and applications. DSS algorithms need further research to meet changing technology and application needs.

In the fourth industrial revolution robots, voice control interfaces and 5G networks play significant role towards advanced real-time autonomous control systems in an industrial domain as well as a social domain. With Arduino-based robots controlled by voice commands for more natural human-machine communications and 5G enabling low latency, high-reliability connectivity as degradation due to typical interference does not matter. This article explores the efficiency and accuracy of voice-controlled interfaces to function robotic attributes via ultra-low latency associated with 5G network links intended for Arduino robots. Methods: An Arduino robot equipped with a voice-controlled interface that utilizes speech recognition and Natural Language Processing (NLP) to understand and carry out commands. This setup was trialed on a 5G network to guarantee connectivity and operational efficiency. Various scenarios and loads were examined in controlled experiments to evaluate response times, precision, and reliability. The 5G has lower latency response time, which led to better command execution. Accurate interpretation of voice commands and real-time adaption to robotic operations for continuous effective behavior across operating conditions and environmental scenarios are demonstrated to highlight the robustness of voice control interface. The combination of voice-activated Arduino robots and 5G networks has paved the way for industrial automation and smart applications, showcasing an innovative approach to human-robot interaction and collaborative robotics. Nevertheless, it is important to analyze the scalability, security, and ethical considerations of these technologies on a wider scale in different domains and applications to guarantee their safe, effective, and equitable implementation.

The growing frequency of natural and manufactured catastrophes necessitates urgently developing efficient response systems to lessen their effects and save lives. This article provides a complete disaster response architecture based on the Internet of Things (IoT) and 5G technologies. The suggested paradigm tackles fundamental flaws in emergency response systems, such as delay, data overload, and fragmented communication routes.
