Abstract

The next generation of wireless technologies for time-sensitive and security-critical IIoT applications is Ultra-Reliable Low Latency Communication (URLLC), an essential enabler. The URLC is a crucial component of processes like automation, real-time monitoring, and remote control, as industrial environments require communication systems that can transmit data in near real-time with high dependability. While older wireless methods have problems with interference and unanticipated delays, innovations like 5G New Radio (NR), time-sensitive networking (TSN), and edge computing are making wireless communication more reliable and predictable. The necessity for a strong security architecture, problems with synchronization, and mobile device handoffs make URLLC integration difficult in industrial environments. The study delves deeply into technology, implementation hurdles, and real-life examples in the automotive, energy, and healthcare industries. Future maintenance driven by AI and ongoing standardization initiatives are among the major themes considered. Based on extensive research, this report presents a future-proof strategy for attaining ultra-wisdom and a cost-effective industrial network. Future IIoT systems can benefit from the suggested architecture's focus on real-time speed, scalability, and flexibility.
