IG 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 (下载) and upload speeds, and better connections. This means that you will be able to download a whole HD movie in seconds and only experience a short delay( 延迟) between sending and receiving data. For example, when you have a video chat with your friend, there is generally a 100 to 200 millisecond delay with 4G, but 5G will decrease the delay to 1 millisecond or less. Which is almost real time.
