Forging a 5G future
The future in sci-fi movies seems so close, yet so far away. Delightfully, 5G technology makes that future look easily achievable. Schools, hospitals, transportation, factories—even our homes will soon
use this powerful wireless network. In 2018, China started testing 5G mobile networks in its several cities. So what is 5G? It's the latest generation of cellular(蜂窝状的）network technology.
5G's benefits mainly come from speed and connectivity（连接性能）.
People will be able to use the Internet at much higher speed than before. Imagine being able to download an entire movie in just a few seconds! That's how fast 5G will be.
For example, one of the biggest problems with developing driverless cars is the delay between sending a signal and receiving it. Driverless cars must be able to react instantly to sudden changes in their environment, such as a dog running across the road. This will require these cars to send and receive huge amounts of data within milliseconds (毫秒). It will also allow doctors to perform operations remotely, using robots. The robots will respond more quickly to the doctors' movements.
So what about 5G's connectivity? Imagine having a smart home that automatically turns the lights on when you open your front door.
"New things become possible when you can move information on a massive scale," Gordon Smith, CEO of telecom equipment reseller Sagent, told The Telegraph. "5G becomes the great enabler."
No matter where it is implemented, it looks like 5G will bring us a more exciting and convenient future.
