1 . Cars could be able to "talk" to each other to warn about dangers on the roads using 5G technology in future, according to researchers.

Researchers at Glasgow Caledonian University (GCU) believe 5G may enable driverless cars to send each other messages about dangers such as ice or deep holes.

And they believe the high-speed, low -delay (低延迟的) nature of 5G will improve driverless cars to the point where they will be safer than the cars being driven today. They predict the number of road traffic accidents which cause more than 1. 3 million deaths and up to 50 million people injured worldwide every year will drop greatly as a result.

Dr Dimitrios, a member of the research group, said, “To have a better idea of what the future will look like, think of having cars that not only use sensors (感应器) to find what's around them, but also can talk to each other about safety information nearby.”

“I'm sure anyone who has had a bad experience on frozen roads would have benefited from knowing about the dangerous conditions ahead of time so they could have changed their speed or, if possible, even avoided that route (路线) altogether.”

With the help of 5G, an early warning system in vehicles will come into use within the next few years. Cars that are close enough to the danger area will pass warning messages to other cars around them using communication technologies, but also to cars further away using 5G, fast and reliably. Then those cars will send the same information to cars near them and 80 on, forming a joined-up.

5G is an exciting mobile technology, which will give a great boost to smart cities and autonomous (全自动的) vehicles among many other things.
