We have been using different wavelengths of electromagnetic radiation to transmit information for hundreds of years. Fibre optic cables are the bedrock of that internet as they manage to transmit electromagnetic radiations containing insane amounts of information. But we cannot connect all devices to it, because many devices are wireless. To make wireless data transmission possible, cellular networks needed to be developed and it all started in Japan, with the first generation cellular network known as 1G. The first generation mobile network (1G) was all about voice. 2G was about voice and texting; 3G was about voice, texting, and data; 4G was everything in 3G but faster, and 5G will be its successor; it will be fast enough to download a full-length HD movie in seconds.
