What is 5G network? Everything About The Wireless Revolution

5G: From Galaxy S21 to new apps, here's what you need to know

What is 5G network? After years of hype and a bumpy first year of launches, carrier 5G networks are here and,

most importantly, 5G-compatible phones like the iPhone 12 and Pixel 5. (Samsung’s next

expected flagship phone, the Galaxy S21, will likely feature 5G too.) The technology is

supposed to change your life with its revolutionary speed and responsiveness. But before we

get into that, it’s important to understand what it is, when and how it will affect you, and how

to distinguish between (the still growing) hype and the reality.

In 2019, CNET held a massive speed test of 5G networks arou nd the world, spanning from Chicago to London to

Sydney to Seoul. The results were a mix of ludicrous speeds, but limited range and spotty coverage. Conversely,

you would see wider coverage with a modest bump in speed. You also saw devices like the Samsung Galaxy S10

5G roll out. The early generation of 5G phones boasted impressive speeds at times, but we cautioned against

buying them because of compatibility issues and other problems that arise with new technology.
