What is 5G?
The “G” in “5G” refers to the generations of mobile network technologies. 1G let us talk to each other, 2G let us send messages, 3G gave us mobile data and the Internet, and 4G made all of these things faster.
Now 5G promises much faster data download and upload speeds, and more stable connections. For example, when you have a video chat with your friend, there is generally a 100 to 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond(毫秒) or less.
What changes will 5G bring us?
According to the Straits Times, 5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment.
Does 5G have any disadvantages?
According to the BBC, though 5G will make our lives more convenient, it will not be perfect.
For one thing, 5G will not “travel” far. On 4G networks, you can be 10 kilometers away from the nearest transmission base and barely lose signal. But 5G will only cover about 300 meters, meaning that we will need more transmitters so that we can get signals. And in order to use 5G, we will have to buy new products specifically designed for 5G that are currently expensive.
