The Internet of Things (IoT) continues to grow in 2025, building on major trends from last year. In 2024, smart cities, AI-powered automation, 5G networks, and cybersecurity advancements set the stage for bigger developments. Now, the focus is shifting toward more intelligent, secure, and industry-specific applications. Businesses are adapting to faster technology, increasing adoption, and stricter security regulations.
In this article, we’ll explore the key IoT trends of 2025 and how they build upon our insights from last year.
Artificial Intelligence (AI) and IoT are now working hand in hand, creating what’s known as AIoT. In 2025, more connected devices process data instantly without sending it to the cloud, thanks to edge computing. This allows faster decision-making, enhancing the Internet of Things' efficiency and responsiveness in critical industries.
Here’s how AI and edge computing are transforming IoT:
As adoption of new technologies grows, AI and edge computing are no longer futuristic ideas—they’re the new standard for industries looking to stay competitive, improve efficiency, and enhance security.
In 2025, network technology is evolving rapidly, making networks faster, more efficient, and more adaptable. 5G adoption has surged, enabling ultra-fast speeds, lower latency, and the capacity to support billions of connected devices. One of the biggest advancements is 5G network slicing, which allows businesses to create dedicated network sections tailored to specific needs. This is helping public safety teams, logistics providers, smart cities, and retailers operate more efficiently. With these improvements, experts predict that the number of IoT devices using cellular networks will reach 5 billion this year.
A significant new development is 5G RedCap (Reduced Capability). It bridges the gap between full 5G capabilities and low-power smart devices, offering reliable connectivity for equipments that doesn't require ultra-high speeds but benefit from efficient power use and lower costs. This makes it ideal for wearables, industrial sensors, security cameras, and smart meters, allowing businesses to benefit from 5G’s reliability while reducing power consumption and hardware costs.
However, 5G alone isn’t enough to meet all connectivity demands. Businesses are combining cellular, low-power wide-area networks (LPWAN), and satellite connectivity to ensure continuous coverage and backup solutions in any environment.
Here’s why hybrid IoT connectivity is becoming the norm:
These advancements mean smart devices are more connected, flexible, and resilient than ever, allowing businesses to stay online, secure, and efficient—anywhere in the world.
In 2025, connected device hardware is becoming faster, more efficient, and more affordable, allowing businesses to deploy more smart devices without high costs.
Key developments shaping IoT hardware this year:
Alongside hardware improvements, open-source technology is changing how IoT devices are built. Companies are increasingly using RISC-V, an open-source processor architecture, to design custom chips without expensive licensing fees.
On the software side, open-source real-time operating systems (RTOS) like FreeRTOS and ThreadX are becoming standard in smart device development. These systems boost security, reliability, and flexibility, making it easier to integrate devices from different manufacturers.
Video and multimedia applications are also evolving. Open-source standards like WebRTC allow devices to handle real-time video and communication without relying on proprietary technologies, reducing costs while improving performance.
With smarter chips, lower costs, and open-source innovation, IoT in 2025 is becoming more accessible, efficient, and adaptable than ever, helping businesses of all sizes harness the power of connected technology.
One of the fastest-growing IoT trends in 2025 is the use of digital twins—virtual copies of physical objects, machines, or entire cities. These models mirror real-world conditions in real time, helping businesses and governments analyze, predict, and optimize operations before making real-world changes.
Here’s how digital twins are making an impact:
Digital twins rely on real-time data. The more detailed and accurate the data, the more valuable these virtual models become for businesses and city planners. As AI and IoT connectivity improve, digital twins are shifting from basic monitoring to proactive decision-making, helping businesses reduce costs, improve efficiency, and plan for the future.
In 2025, eco-conscious initiatives are no longer optional—it’s a key reason why businesses and governments are investing in IoT. Smart technology is helping companies reduce energy waste, optimize resources, and cut carbon emissions like never before.
Where connected solutions are making a real impact:
Beyond these benefits, environmental regulations are tightening, and companies face increasing pressure to meet carbon reduction goals. IoT provides the data, automation, and insights needed to track and improve sustainability efforts, making businesses more eco-friendly while also cutting costs.
As climate concerns grow, smart solutions will continue to be a key tool in building a greener future, helping industries operate more sustainably while staying competitive.
The use of connected devices is skyrocketing, transforming industries and becoming a core part of modern infrastructure. In 2023, there were 16.6 billion connected devices in operation in the world. By the end of 2024, that number climbed to 18.8 billion. Estimates suggest IoT adoption will continue at a rapid pace, with projections ranging from 40 billion connected devices by 2030.
This rapid growth shows that Internet of Things is no longer just an experiment—businesses are fully integrating it to boost efficiency, cut costs, and improve decision-making. Despite economic challenges, companies recognize that automation, real-time analytics, and smart connectivity give them a competitive edge.
A major shift in 2025 is the rise of industry-specific solutions. Businesses are no longer relying on one-size-fits-all platforms—instead, they’re choosing tailored technologies designed for their specific needs. As demand for customized solutions increases, IoT providers are delivering hardware, software, and analytics built for individual industries.
With more connected devices comes a bigger risk of cyberattacks. Hackers are targeting unsecured devices, using them to steal data, launch large-scale attacks, and disrupt operations.
To fight back, companies are strengthening IoT security at every level:
On top of this, governments are enforcing stricter security laws. New regulations require:
As more industries adopt Internet of Things, businesses must balance innovation with security. Protecting data, devices, and networks is no longer optional—it’s essential to ensuring safe, reliable, and future-proof systems.
Governments worldwide are strengthening security and privacy laws to keep up with the rapid expansion of IoT. In 2025, new regulations are setting higher security standards, stricter compliance requirements, and improved data protection for IoT manufacturers and users.
Here are some of the key regulations shaping the industry this year:
Beyond security, regulators are also focusing on interoperability and data governance:
As IoT adoption grows, these regulations and standards will shape the industry, making security, compliance, and interoperability top priorities for businesses and manufacturers.
The technology landscape in 2025 is evolving faster than ever, bringing smarter technologies, wider adoption, and a greater emphasis on security. Businesses are using edge computing, AI, and improved connectivity to make better decisions, optimize operations, and gain deeper insights in real time.
However, with this growth comes greater responsibility. Governments and businesses alike are prioritizing security, reliability, and interoperability to ensure that connected systems remain safe, efficient, and scalable. The days of unchecked expansion are shifting toward a more structured, secure, and sustainable approach. Companies that focus on compliance, cybersecurity, and adaptability will be best positioned to succeed.
Looking ahead, intelligent networks and automation will continue to shape industries—creating smarter, more secure, and more efficient solutions that redefine how we work, live, and connect.
