How will 5G technology improve the Internet of Things (IoT)? (2023)


The first5G networksare being launched worldwide today in anticipation that this advanced mobile technology will play a key role in the digital transformation and economic prosperity of many countries. 5G and IoT are expanding very rapidly, as is the number ofconnected deviceswill fluctuate from 645 million to 3.4 billion by 2024. While numerous factors are contributing to this increase, one of the most important is the development of 5G networks. The upcoming launch of 5G communications is good news for the IoT market. This is mainly because 5G networks will greatly improve the performance and reliability of these connected devices.

According to reports, 5G will be more than 10 times faster than LTE networks. This speed maximizes the ability of IoT devices to connect and transfer data very quickly. For example, in smart home devices, this speed boost helps slow down and improve overall speed when connected devices send and receive data and notifications. With the exception of smart home devices, almost all IoT devices will benefit quickly, including those with healthcare and industrial applications.

5G and IoT technology

Transmission technology plays an essential role in Internet of Things (IoT) technology. It automatically makes the new 5G communication technology essential for IoT. 5G aims to make device connections faster and more efficient and minimize delays.

5G can be divided into three frequency bands: low, medium and high. Medium bandwidth offers faster connectivity than 4G nearby, allowing for improved mobile broadband connectivity or better machine-to-machine communications. This means that hundreds of IoT devices can use 5G in a small space without burdening the infrastructure. With the increasing data rate of the devices, the accuracy of the devices also increases with the help of machine learning; As a result, IoT devices work faster and their reliability characteristics are getting better every day.

Improving industrial autonomy through 5G connectivity is one of the most important prospects for IoT devices. The first generation rendering services were followed by the second and third generations with voice and messaging services and internet access, and later the fourth generation (4G or Long-Term Evolution [LTE]) offered video streaming capabilities.

From 2023, the fifth generation of mobile communications (5G) should have a global reach. The power introduced by 5G technology is undeniably exciting, but adoption is fraught with difficulties and risks.

IoT challenges in 5G

Some significant challenges of 5G and IoT innovation are:

  • Frequency Bands/Spectrum Availability: 5G networks require frequencies of up to 300 GHz to deliver speeds, which is 20 times faster than 4G LTE networks.
  • Deployment Coverage: High frequencies enable more precise radio waves capable of beam shaping. 5G antennas need to be in close proximity to handle large volumes of users and data. Many basic antennas and channels will likely be smaller in the 5G era. Still, cities need to install additional multipliers to spread out the waves and increase their width while maintaining a constant speed in the most dense areas.
  • Shortage of 5G devices: Limitations of 5G phones compared to non-5G phones on the market are a concern. The planning of the 5G transmission is determined by the availability of 5G devices, the number of which is small. In addition, various technical challenges with multiple bands, often at high and low levels, pose design challenges for the vestibule. It can also lead to radiation problems due to the high power in the transmission of high-frequency bands, which significantly affects high-bandwidth performance and data plane affects.
  • radiation: Like all other radio waves, 5G also emits electromagnetic radiation. The concern is that radiation can harm humans and other living things. Additionally, an increase in the number of transmitters or cell towers installed to cover 5G will increase exposure to these radiations, affecting more people than ever before.
  • privacy and security: In a data-driven technology, 5G IoT deployments will withstand both common and complex online security threats. Communication will increase at faster data speeds than ever before. It will force cloud-based services and data to be as airtight as possible to protect user data and privacy. Likewise, users need to be careful with their data managers. 5G will not be easy initially, and challenges will loom as we step into this new age of communications.

However, the benefits still far outweigh the concerns, as the 5G release will also reflect the dawn of autonomous vehicles, smart cities, next-gen homes and more.

Current industries that will continue to benefit from these 5G IoT improvements include industrial intelligence, smart buildings, cities, smart resources, security and surveillance, agriculture, retail and healthcare.

5G IoT applications

There are various IoT applications in 5G, such as:

  • You canPark a smart car in a parking garageand wireless charging via the city network while you work.
  • You can remotely summon a car to drive itself from the parking garage to your office door.
  • Farmers in rural areas canMonitor and track crops, livestock, and machineryeasier with drones and super-dense sensor networks.
  • Home users can fully integrate the COVID-led work-from-home paradigm that is likely to survive the pandemic as the new business norm. In addition, home users can optimize power consumption and stream their favorite entertainment from anywhere.
  • Society can become more efficient, Smart Cities can live up to their name, and users can expect personalized information streams tailored to their desires.


With today's huge reliance on large-scale mobile phones, the future of 5G and the Internet of Things will completely change the world in the next 20 years. However, that day is not far off when vehicle and utility devices such as waste management and power generation will reduce greenhouse gases and pollution through smart grids and intelligent environmental monitoring. However, there is still a long way to go before 5G is fully deployed worldwide. It is believed that by 2025, 4G will still drive 45% of connected devices and 5G will only support 49%.
