It may be true that the industry was a little overly aggressive/optimistic with its marketing but in no time, you’ll be wondering how people lived with the old 4G.
Technology implementation/integration takes time.
After all, the vision for 4G was laid out in 2002, the infrastructure was tested in 2007, the first 4G phones hit the U.S. market in 2010, apps became popular in 2013 and now you take it for granted.
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.
Despite the pall of this past year, the benefits and potential applications for 5G were so far reaching that technology producers, service providers and application developers continued to make progress with more than 100 service providers around the globe commercializing the technology.
As the world entered 2021:
• 8 countries had shown download speeds in excess of 40 Mbps
