description Machine-type Communication (MTC) plays an imperative role in wireless networks and becomes the dominant communication paradigm for various real-time applications including industrial automation, public safety, healthcare, utilities, transportation, smart cities, and numerous other applications. Hence, wireless system is expected to a larger extent, will be used in the context of MTC. Mission-critical MTC (mcMTC), also referred to as Ultra-reliable Low-latency Communication (URLLC), has become a research hotspot. It is primarily characterized by communication that provides ultra-high reliability and very low latency to concurrently transmit short commands to a massive number of connected devices. However, mcMTC poses significant transmission challenges over wireless channels, as it is prone to channel noise, interference, distortion, and bit synchronization errors. In addition, supporting small data communications for concurrent connection for a massive number of MTC devices and providing insights in trade-offs between latency and reliability have been neglected. The mcMTC has a significant technical impact on the design of all layers of the communication protocol stack. While the reduction of PHY layer overhead and improvement in channel coding techniques are pivotal in reducing latency and improving reliability, the current wireless standards dedicated to support mcMTC rely heavily on adopting the bottom layers of general-purpose wireless standards and customizing only the upper layers. As such, the PHY layer design requires further analysis to realize the stringent requirements of mcMTC. In this study, an innovative architecture is proposed for mcMTC applications through PHY layer named Mission Critical WiFi (MC-WiFi) targeted at reducing the end-to-end (E2E) latency by minimizing the packet transmission time and improving the reliability by proposing a one preamble symbol Packet Detection and Channel Synchronization (PDCS) algorithm and implementing of polar codes in the wireless channel. Mathematical results show that the proposed architecture allows a substantial reduction in packet transmission time, down to 5 μs and guaranties error probability at 1
