High costs, the use of old technologies, broken supply chains, a lack of production visibility, incongruency on what to measure and a lack of IT/OT integration are just a few factors keeping factories from running at full capacity.To overcome these inefficiencies, companies are looking for new technologies and new processes to improve performance. Enter the Industrial Internet of Things (IIoT).Industry 4.0 takes advantage of IoT to deliver predictive and prescriptive maintenance programs, self-healing production lines with near zero downtime, remote control processes, autonomous robotics, and augmented reality systems. These capabilities require better connectivity throughout the factory floor.As result, wireless connectivity is becoming even more business and mission critical, leading to more stringent requirements regarding reliability, latency, and security. Not all wireless technologies today meet the increasing demands of smart manufacturing, leaving an opportunity for 5G to fill the void.This whitepaper by James Brehm & Associates discusses the challenges plant operators face on their production floor and how wireless technologies can make today’s factories more efficient. Furthermore, it talks about the importance of Radio Frequency (RF) testing on the factory floor.
