5G is an investment for the next decade, and in previous mobile transitions, we’ve seen most of the big changes happening years after the first announcement. Take 4G, for instance. The first 4G phones in the US appeared in 2010. But the sorts of 4G applications that changed our world didn’t appear until later. Snapchat came in 2012, and Uber became widespread in 2013. Video calls over LTE networks also became widespread in the US around 2013.  The actual 5G radio system, known as 5G-NR, isn’t compatible with 4G. But all 5G devices in the US, to start, will need 4G because they’ll lean on it to make initial connections before trading up to 5G where it’s available. That’s technically known as a “non standalone,” or NSA, network. Later, our 5G networks will become “standalone,” or SA, not requiring 4G coverage to work. But that’s a few years off.
