How 5G Works

Like previous cellular network generations, 5G uses radio waves to transmit data between cell towers and devices like smartphones. However, 5G operates at super high radio frequencies between 30 GHz and 300 GHz. The higher frequency allows more data to be transmitted per second compared to 4G LTE networks.

5G also utilizes advanced antenna technology like multi-input multi-output (MIMO) and beamforming. This allows the cellular signal to be directed and concentrated in specific directions for users which improves speeds and capacity.

Additionally, 5G networks are software-defined, meaning network functions can be dynamically adjusted for optimal performance using cloud computing and virtualization. This makes the network more flexible and efficient.

Benefits and Improvements of 5G

There are many exciting improvements 5G will bring compared to 4G and earlier networks:

Faster speeds – 5G is designed to support up to 10Gbps download speeds with an average speed of 100Mbps expected. This is roughly 10-100 times faster than 4G LTE.

Lower latency – Latency refers to the time it takes for data to travel between points. 5G aims for 1ms latency, which can enable real-time communication for things like online gaming, self-driving cars, etc.

Capacity – 5G will allow many more devices to connect per area without congestion. Up to 1 million devices per square km can be supported.

Reliability – 5G uses network slicing technology which allocates customized virtual networks for different types of devices and applications. This improves reliability for things like smart grids, industrial IoT, etc.

Efficiency – Thanks to advanced antenna and signaling technologies, 5G achieves up to 10 times better energy efficiency and data transmission rates compared to 4G.

5G Use Cases

5G opens the door to many new applications and use cases that were not possible before.

Here are some examples:

– Augmented reality / virtual reality – The fast speeds and low latency of 5G will take AR/VR experiences to the next level.

– Autonomous vehicles – Self-driving cars require a network with ultra-reliable, low-latency connectivity which 5G enables.

– Industrial automation – 5G will allow time-sensitive systems like robotics and manufacturing to be controlled remotely in real-time.

– Remote patient care and surgery – Doctors can monitor and treat patients remotely over fast and reliable 5G networks.

– Smart cities – 5G will allow cities to embed thousands of connected sensors to monitor and automate municipal services.

– Enhanced mobile broadband – Consumers will experience fiber-like internet speeds on their mobile devices for immersive apps, cloud gaming, 4K video streaming, and more.

When Will 5G Arrive?

5G Rollout in the UK

In the UK, EE, Vodafone, Three, and O2 have all begun limited 5G rollouts in 2019-2020 focused on major cities like London, Birmingham, Manchester, and Edinburgh.

The goal is to continue expanding 5G coverage nationwide throughout the 2020s as more 5G compatible smartphones are adopted and an additional 5G spectrum is auctioned off. By 2027, the UK government aims to have the majority of the population covered by a 5G signal.

Over the next few years, 5G coverage is expected to rapidly spread to towns, rural areas, and worldwide. The full transformation to 5G will take place over the decade as more spectrum is auctioned, infrastructure is updated, and more 5G compatible devices are adopted.

Conclusion

5G is set to catalyze the next generation of innovation and disruption across industries. With radical improvements in speed, latency, reliability, and connectivity – we are entering an exciting era where nearly everything can be connected to the benefit of consumers, businesses, and society as a whole. However, the full potential won’t be realized overnight. The transition to a mature, fully-featured 5G world will occur gradually throughout the 2020s.
