    Our smartphones are amazing, but our connections can be so slow. The future in sci-fi movies seems so close, yet so far away. 5G technology makes that future look easily achievable. Schools, hospitals, transportation, factories- even our homes will soon use this powerful wireless network. Read on to see the ways 5G will change our world.

The initial hype（宣传）around 5G seems to be all about phones. Last year, China started testing 5G mobile networks and the Hongkou district of Shanghai was the first to implement（实行）a 5G network.

But 5G has the ability to transform more than just phones. It has huge influences for robots, cars, health devices, retail and nearly every industry you can think of.

5G is the latest generation of cellular network technology. It is faster and more stable than 4G, the previous generation. The benefits of 5G come mostly from its speed and connectivity. The advantage of higher speeds is fairly obvious-people will be able to browse the internet and watch videos at a much greater speed than before. Imagine being able to download an entire movie in just a few seconds!

But speed brings other advantages that might not be so apparent. While there are many challenges in developing driverless cars, one of the biggest technical problems is latency, which refers to the delay between sending a signal and receiving it. Driverless cars will need to be able to react nearly instantly to sudden changes in their environment. This will require these cars to process huge amounts of data within milliseconds.

So what about connectivity? 5G will allow us to develop “smart” environments. Imagine having a smart home that automatically turns the lights on when you open your front door.

No matter where it is implemented, it looks like 5G will bring us a more exciting and convenient future.
