What exactly is 4G? even the experts can’t decide. But Engadget has posted a good summary of the network terms we’ve used for the past few years and how 4G fits. From the summary:
“It’s hard to believe nowadays, but in a simpler time, cellphones really were called “cell phones,” not dumbphones, smartphones, feature phones, or superphones. They bulged in your pocket — if they fit in your pocket at all, that is — and they made calls. That’s it. None of this social networking, messaging, browsing, Instagramming, Flash 10.1 nonsense. They didn’t upload 5 megapixel photos to Flickr, and they most certainly didn’t turn into wireless hotspots.”
