24. 5G networks еntered the scene in 2020.
Or at least most internet stats and estimates say so. 5G networks, in essence, are way faster than 4G connections. Duh.
The crucial detail lies in just how much faster they are. An ordinary 5G connection would have an average download speed of about 1GBps. Should such connection come to us, the internet will have the needed infrastructure to finally support IoT devices on a mainstream level.
