IoT trends for 2024

Here are our predictions for the top ten IoT trends we’ll see this year.


Continued growth in the number of connected devices

It hardly requires a crystal ball to predict that the number of connected IoT devices will continue to grow in 2024. Currently, according to Statista, there are approximately 15 billion connected IoT devices. That’s equivalent to just under twice the total number of people in the world (eight billion).

It is expected that there will be more than 17 billion connected by the end of 2024. By 2030, the number is expected to reach nearly 30 million. Increasingly, they will be smart devices augmented with artificial intelligence (AI).


A greater focus on cyber security 

Cyber security can often be an afterthought or overlooked when it comes to both the design and implementation of IoT connected devices. Stories abound how poorly protected devices have enabled access onto wider business networks.

However, the need to maintain the trust of customers and employees should be a priority, meaning data and device security must be further up the agenda when it comes to IoT deployments. In recognition of this fact, the IoT security market is expected to see significant growth: from $3.35 billion in 2022 to $13.36 billion in 2028 – a CAGR of over 26%.


Further rollout of 5G networks

Improvements to connectivity will drive further growth as well as improved performance. In particular, wider 5G rollout will pave the way for breakthroughs in smart city technologies, edge computing use cases and autonomous vehicles.


Smart buildings

The need to achieve net zero – and the huge contribution the built environment makes to the global carbon footprint – is driving a great deal of IoT investment in smart building solutions. Using sensors to monitor conditions such as temperature or footfall around buildings in order to optimise services like HVAC and lighting helps to lower energy use, improve the employee experience and deliver costs savings to the business.


Smart cities

Cities are equally investing in the IoT to help them achieve their net zero and sustainability goals. Investment ranges from public transportation systems, utilities and services provision, footfall and traffic monitoring and energy use. As well as increasing efficiency, these innovations will help to reduce costs, improve the visitor experience and enhance the quality of life for citizens.


Electric vehicles

There is a huge need to invest in electric vehicle (EV) infrastructure, especially here in the UK. This will drive the connection of a huge array of charging stations and other infrastructure devices. In the rush to rollout this infrastructure, it is important that cyber security is not overlooked. The safety of the vehicles and our city streets, as well as the huge swathes of personal data these vehicles collect, depend on it.


Healthcare applications 

Healthcare is one of the most exciting areas for IoT innovation. The possibilities to optimise patient experience and healthcare results through the monitoring of individual patient devices, such as insulin monitors and oxygen machines, are vast. By combining the vast quantities of data collected by these machines with AI tools for analysis and predictive analytics, a whole new exciting frontier of healthcare is opening up.



Until now, the biggest growth in wearables has been in smart watches and fitness trackers. Use of eyewear, such as Microsoft HoloLens, has been restricted to fairly niche use cases.

Meta’s collaboration with iconic sunglasses brand Ray-Ban, which saw a new launch in the middle of last year, hopes to buck this trend. The latest Ray-Ban Meta Smart Glasses are designed for everyday use. They can make calls, send texts, control features and find answers for those random questions that pop into your head throughout the day.

While Apple finally introduced the first iteration of its extended reality headset, Apple Vision Pro, which enables people to see both AR and VR content in mid-2023, it seems work is continuing at Apple to produce a lighter weight version of smart glasses that would be an iPhone companion. If and when Apple finally releases such a product, we can expect a much wider adoption of this type of wearable.


Generative AI integrations with IoT solutions 

Some of the biggest tech news of 2023 centred around generative AI, including the launch of Chat-GPT-4 and Amazon Q. When these technologies are integrated with IoT solutions, it will bring brand new capabilities to the internet of things. AI integration will make devices smarter and more autonomous. We can expect to see a spike in innovative use cases.
