Manufacturers applying wireless technologies in new or existing automation systems for sensing, monitoring, and controlling equipment and processes can reap benefits by eliminating costly cabling and enabling mobility and deployment flexibility. Meanwhile, using wireless technologies can improve factory-floor operating conditions, performances, and efficiency. It is envisioned that the industrial wireless infrastructure will become a common infrastructure for communication, computing, and even sensing. The industrial use cases are also among the drivers of the evolution of cellular, Wi-Fi, and even satellite networks. In the recent years, technology vendors are achieving significant progresses while the expectations from system integrators and users are increasing even more rapidly, which means many challenges are being solved while many new ones are being brought up.
