Our smart phones are amazing, but our connections can be so slow. The future in science-fiction movies seems so close, yet so far away. 5G technology makes that future look easily achievable. What is 5G? It’s the latest generation of cellular (蜂窝状的) network technology. It is faster and more stable (稳定的) than 4G. This powerful wireless network will change the way we live.
Transportation
With the introduction of 5G and smart technology, traffic lights, buses and even cars begin to communicate with each other. We will be able to check traffic flow so that traffic jams (拥堵) may soon become a thing of the past. Moreover, it’s reported there is a good possibility of seeing driverless cars on our roads. With the help of 5G, these cars will be able to react to sudden changes in their environment at once, such as a dog running across the road.
Medical treatment
With 5G networking, all the people can have the chance to use top medical resources. Before treatment, 5G will support video calls with doctors and provide advice for those who can’t visit a hospital at once. After being treated, wearable tech will send information to doctors in no time, allowing hospitals to monitor the patients from their homes. It also allows surgeons to perform operations remotely, using robots. In March, 2019, China completed its first 5G-based human brain surgery between a doctor and a patient located more than 4,000 kilometers away. Five months later, robots guided by Beijing doctors completed a test operation in three different locations at the same time!
It seems that 5G will make our life more exciting and convenient wherever we use it.
