Your Internet experience is terrible when the net speed is too slow—it takes so long to open a web page and the film you’re watching stops every few minutes. That can be very annoying. But it could be a thing of the past. In the near future, major telecom carriers will start to provide 5G services.
What is 5G? What difference will it really make to our lives? 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 ore stable connections. This means that you will be able to download an entire HD movie in seconds and only experience a short delay between sending and receiving data. For example, when you have a video chat with your friend, there is generally a 200 milliseconds delay with 4G, but 5G will reduce the delay to 1 millisecond, which is almost real time.
5G will be able to improve many advanced technologies, such as driverless cars, wearable devices and entertainment. With a 5G network, the short delay in information exchange will allow driverless cars to run more safely, as they will be able to communicate in real time and avoid dangers. Meanwhile, 5G-enabled wearable devices will keep doctors updated on the health status of their patients, so doctors can give patients advice immediately if there’s something wrong. Besides, VR games will become more popular with 5G. The short delay of 5G will make the games feel even more real.
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 kilometres away from the nearest transmission base and barely lose signals. But 5G will only cover about 300 metres, 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.

Mind maps are a great way of showing a picture of information that you need to learn. You can use mind maps for all kinds of learning. They work very well for vocabulary when you are learning a new language. |
Draw a circle in the middle of the page and write the vocabulary subject in the middle. For example: transport |
Brainstorm some word groups for transport and think of headings for each one. For example: •sea transport •land transport •air transport For each one, draw a short line from the centre circle outwards. Add another circle and write the new group word in the middle. |
Look at each group and try to add more groups. For example, in “land transport” there are two sub-groups: •road •rail Draw two more lines, add two more circles and write the two new headings inside them. |
When you can’t make any new groups, add a line for each word you know. Write the words along the lines or, if you have space, write them inside more circles. |
As you learn new vocabulary, add it to the mind map. |
To make the mind maps even better, use colours to show important ideas or parts of the map. |
