The recent diplomatic dust-up over Chinese telecoms company Huawei, one of the leaders in developing equipment for fifth-generation mobile networks, has demonstrated that this technology which promises to enable an internet of things and self-driving vehicles also poses risks.

What is 5G, what will it be able to do, and what are the risks?

What is 5G?

5G stands for the fifth generation of mobile network technology, which should begin to be rolled out in 2020 in Asia and the United States.

Each generation has offered improvements in data transmission speed and capacity, and with 5G the networks are really set to make the transition from telephony to other objects.

What will it be able to do?

The much vaunted internet of things has so far been hobbled by the limitations of mobile networks, both in terms of transmission speeds of handsets and the fact the backbone of networks hadn’t been expanded sufficiently in many cases to handle huge volumes of data.

With 5G, transmission speeds should accelerate sufficiently to allow for self-driving cars to take to the roads or for doctors to conduct operations remotely.

It will also cut the cord on augmented and virtual reality.

The ability to connect more sensors will help make many services “intelligent”, such as helping manage traffic flow and telling the sanitation department when garbage bins need to be emptied.

Industry is in particular looking forward to 5G to reinvent manufacturing and allow it to monitor all sorts of processes.

Why does 5G pose security risks?

The first reason is that more data and more types of data will be travelling across 5G networks. Much of the data transmitted by sensors could be sensitive, such as information about manufacturing processes that business rivals would be interested in acquiring. Or the data from our homes that could be gleaned to determine all sorts of things about us. The treasure chest of data for hackers is getting much, much bigger.
