5G offers ultra-fast speeds and mobility in a way that previously was not possible. Compared to the 4G network, 5G is already set to be as much as 20 times faster than 4G, with speeds of up to 20 gigabits per second. To put this into perspective, 4G LTE has a peak speed of just 1 gigabit per second. This will change the way we do business, travel, communicate, and live our day-to-day lives.

Most of these changes will come through unleashing the full potential of connected devices, otherwise known as the Internet of Things (IoT).

Combined with 5G technology, the proliferation of ‘smart devices’ & artificial intelligence (AI) is expected to drive further innovation of IoT, resulting in greater technological milestones and new levels of economic growth.

IoT technologies such as machine-to-machine communication combined with the ultra-fast 5G network are set to drastically change the landscape of various industries. We will begin to see IoT-connected businesses that rely on greater automation, including industry-specific functional needs.

For example, retail workers equipped with augmented reality (AR) and virtual reality (VR) headsets will be able to make important stock/inventory assessments on the floor while connected to the 5G network. Since IoT devices and data simulate every business process, errors or mistakes that may have been missed can be picked up through simulations, improving business efficiency and service.

What is 5G?

5G is the next leap forward in mobile network technology. Succeeding the 4G network, 5G builds on the foundation of 4G, bringing a more seamless and faster data experience.

Right now, 4G LTE is operating on lower radio frequency bands of up to 6GHz, whereas the 5G frequency band will be able to handle anywhere between 30GHz and 300GHz. Because 5G can operate at such a high frequency, network speed will be the fastest of any and will be able to support massive data transfers.

Since 5G has the capacity to handle up to a million devices per square kilometre, you will experience fewer issues with dropped connections like you do on the 4G network. Along with 1G, 2G, and 3G networks, 4G relies on an orthogonal frequency multiple access. These are allocated time slots dedicated to each user device. The more devices on the same frequency jostling for these time slots, the more we experience latency and reduced bandwidth. With 5G, we will see increases in data rate and bandwidth, improved network coverage, and reduced end-to-end latency which are all important properties to support IoT devices.

By using non-orthogonal multiple access (serving more than one user in the same time slot), we can squeeze in a lot of IoT users/devices with different quality of service requirements. In this sense, the concept of non-orthogonal approaches is very exciting and perfect for the Internet of Things. Such improvements and achievements in speed delivery will make way for innovative IoT solutions to support various industries.
