There were about 1.11 billion connected wearable devices worldwide in 2022. The argument for robotics and AI, among many new technologies, to improve workplace safety through reduced exposure to hazardous tasks was supported by 45% of respondents in a survey of more than 9,000 workers across nine countries.

RESTRAIN:

• Overcoming Challenges in IIoT Adoption Addressing Interoperability Security and Legacy System Upgrades

The communication protocol and interoperability standardization are the essential factors hindering the growth of the IIoT market. The IIoT ecosystem consists of many devices, platforms, and networks designed by various vendors, which leads to compatibility problems. The lack of interoperability and seamless communication between different platforms makes it difficult to exchange data and integrate systems on the shop floor, which slows down the adoption of different IIoT solutions. Besides, there is a significant impact on businesses in upgrading the legacy systems to close the loop on newer IIoT technologies, causing a bottleneck in implementations. Data safety and privacy is another large hurdle. With the interconnectivity of industrial operations comes a growing threat of cyberattacks and data breaches. Therefore, industries should focus on effective cybersecurity techniques to safeguard delicate data and stay up and running. Unfortunately, countless organizations do not have the experience or resources to tackle such threatening things. Inherently conservative industries are slow to change, and these issues are further contributing to making IIoT adoption difficult.
