I decided to do some reading on 4G and see what all the fuss is about.
Now I know.
If my understanding is correct, it just switches all communications to a really fast IP-switched data network. In contrast, 3G used circuit-switched technology for voice and IP for data. 4G implements VOiP for calls, so there's no need for separate networks for voice and data. And looking at the theoretical speeds (100 Mbit - 1Gbit/ sec), I can clearly see what the commotion is about. I would LOVE to work on implementing this network. Can't wait till I can at least access it here lol.
