IoT with 5G Network: A new Era of Technology and Risks


Let's first define what the Internet of Things truly is before we go into the topic at hand. The phrase "Internet of Things" (IoT) refers to a network of physical objects, including vehicles, appliances, and other machinery, that have been outfitted with sensors, software, and network connectivity to facilitate the gathering and sharing of data.. One of the key technologies of the twenty-first century is undoubtedly the Internet of Things. Now that commonplace items like vehicles, baby monitors, thermostats, and kitchen appliances can be connected to the internet through embedded devices, communication between people, processes, and things may happen seamlessly.

The Impact of 5G on IoT devices

As we know 5G is the latest evolutionary step in the world of mobile communications which is basically the utilization of Fifth Generation of wireless technology. It is the first mobile network that has been designed from the ground up to support IoT use cases. This is why it has all the ingredients to utilize such devices to perfection. Some of those features are:

  •  Data-Transfer Speeds
    The commercial success of any IoT is ultimately tied to its performance, which is dependent on how quickly it can communicate with other IoT devices, smartphones and tablets. Reports state that 5G networks will operate ten times faster than the existing LTE networks. IoT devices will be able to exchange data and communicate more quickly than before thanks to this speed boost.

  • Greater Network Reliability
    For any IoT, but particularly for linked devices like locks, security cameras, and other monitoring systems that rely on real-time updates, having a dependable and stable network state is crucial. 5G devices tend to operate on much more secure networks compared to their predecessors. This coupled with their ability to handle more connected devices helps consumers benefit from greater reliability of their connected devices. 

  • Improved Communications
    5G technology improves the predictability and security of data, providing a significantly faster response which can be used in autonomous vehicles or collaborative robots 

Real Life Applications

Imagine being able to park a smart car in a parking garage and gaining wireless charging through the city grid while you work. Then you can message your vehicle to drive from the parking garage to your office door. This is where 5G IoT devices could come into play. They are already being used in video broadcasting, mobile computing, Fixed Wireless Access(FWA) and high speed industrial networking. 

At the current rate this will also have large scale usability and implications in the future. In the next 20 years we could see this being applied to mass produced autonomous vehicle deployments and energy production through smart grids and environmental monitoring to reduce greenhouse gases and pollution. Farmers could also monitor and track crops, livestock and machinery through drones and super-dense sensor networks.

Risks in this New Era

  • Security
    The IoT-5G ecosystem’s sheer scale presents an enormous attack surface. As more devices connect to 5G networks, malicious actors have more entry points for cyberattacks.

  • Privacy
    The abundance of data collected by IoT devices raises concerns about user privacy. Unauthorized access to personal information would still be a looming threat.

  • Data Integrity
    The sheer volume of data exchanged between IoT devices demands rigorous data integrity measures. Ensuring that the data remains unaltered in transit is essential for critical applications, such as healthcare and autonomous vehicles.

  • Environmental Impact
    As the number of IoT devices skyrockets, concerns about the environmental impact of e-waste and increased energy consumption come to the forefront.

Navigating these Threats

  • Cybersecurity
    Implementing advanced security measures is paramount. This includes encryption, access control, and regular security updates to protect data and IoT devices.

  • Consumer Awareness
    Educating consumers about the potential risks and the importance of security settings can help protect their data.

  •  Fail-Safes
    Building redundancy and fail-safe mechanisms into IoT-5G networks can enhance reliability and availability.

  • Data Governance
     Implement strict data governance and privacy policies to safeguard user information. Compliance with regulations like GDPR is crucial.


The fusion of IoT and 5G networks signifies a remarkable leap in technological progress. However, the advantages of this convergence are accompanied by significant risks.  Securing this digital ecosystem would require a collaborative effort from governments, industries, and individuals. As we collectively make headway into this new era of connectivity, understanding the dynamics between technology and risk will be essential to harnessing the full potential of IoT on a 5G network. In this ever changing landscape, thoughtful and contemplative decisions are needed to reap the rewards while mitigating the dangers of our increasingly connected world.
