KEY FINDINGS

COVID-19 PANDEMIC

Remote Work Shift  Surge in Enterprise IoT Adoption

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

The COVID-19 pandemic has had a dual influence on the IoT ecosystem, one being disruptions in supply chains, production, and business operations, while the other fast-tracking the acceptance of connected technologies into the industries. The supply chain, factories, and nonessential commodity operations, induced by lockdowns, experienced increasing delays in production of IoT devices, shortage of chips, and temporary nonessential enterprise IoT investments. This newly laid-down principle almost fast-tracked the IoT solutions in domains such as healthcare, remote monitoring, and automation. However, this matching on the road to implementation of IoT solutions revealed several of its challenges and barriers to adoption. A growing concern for cybersecurity threats and security vulnerabilities called for enhanced data protection for connected devices.

Having said that, the pandemic might have initially slowed down IoT growth, but it served better as a catalyst thereafter. Now, every industry is adopting IoT at lightning speed. In the post-Covid era, IoT will be pivotal in evolving smart city development, healthcare makeover, and industrial automation, as connectivity, data collection, and analytical decision-making become the nerve center for industries.

LATEST TRENDS

Increased AIoT Adoption  Strengthened Cybersecurity Measures

The latest trend in the IoT market is the convergence of Artificial Intelligence with IoT, that is AIoT ie Artificial intelligence of things. The AI-enhanced IoT will have applications not just for device automation and remote analytics but also in real-time data analytics, predictive maintenance, and automated decision making.

This Health and AIoT have howled up the effect of smart cities and greatly screened other sectors like manufacturing and healthcare with ideas of creating highly automated and efficient systems and cybersecurity approaches for improvement. For example, predictive analytics based on AI in the IIoT-enabled environment predicts equipment failure before it actually happens within the plant environment, thus lowering the chances of downtime and reducing maintenance costs. While the healthcare systems integrate more of this technology, the AI-based IoT technology provides better remote monitoring of patients and medical diagnostics; smart cities now leverage AI-driven IoT architectures to optimize their traffic management, energy consumption efficiency, and safety for the public.

• According to IoT Analytics (State of IoT Summer 2024), the number of connected IoT devices grew by 15 %, reaching 16.6 billion globally in 2023, and is projected to reach 18.8 billion by the end of 2024.

• As reported by the US National Institute of Standards and Technology (NIST), 159 organizations are currently collaborating within the Industry IoT Consortium to standardize IIoT tools and protocols as of early 2024.
