1G was the very first wireless telephone technology, originating in the 1980s, and used analogue radio signals to transmit voice calls. 2G arrived in the 1990s, and used digital signals which enabled phones to send text and picture messages.
In the early 2000s, 3G came in which allows us to be able to video call others and use the internet from our phones. Then came 4G in 2010 which allowed for faster mobiles speeds that made browsing the internet and streaming video a breeze.
5G will have some similarities to 4G. However, it will have more reliable mobile connection speeds than ever before, as well as the ability to handle thousands of connections without a compromise on connection quality. 5G will transform every individual communication within our lives. No longer will we be just be able to connect to other people around the world. Every object and thing will be connected too. This includes everything from being alerted about potential collisions whilst driving your car, to your coffee machine being linked to your alarm clock so that it has a drink ready as soon as you wake up.
