In the media, 5G is featured in the general context as an amazingly fast data transfer technology. This is true, but few journalist emphasize that two versions of 5G access will be available on the market. One of them is sub-6 - it's technology that supports bands below 6 GHz, while the other is mmWave, which is shortcut from full name millimeter wave, and it's supports bands above 6GHz. These details may prove to be an additional advantage for the most expensive variant of the iPhone 12 coming to the market.
The latest information indicates that only the iPhone 12 Pro Max will support 5G in the form of mmWave. The remaining models in the iPhone 12 series will also support 5G, but they will support bands below 6GHz. However, it is worth noting that the availability of mmWave bands around the world is very limited. Network operators have not yet implemented such technology in too many countries and currently it can only be found in the United States, South Korea and Japan. It is very possible that the iPhone 12 Pro Max will receive support for mmWave only in these markets, while the most powerful model of the iPhone 12 in other countries will also receive 5G support in the sub-6 option.
