Wired: "If your smartphone seems more like a slowphone, hang in there. The next generation of wireless technologies, known as 4G, promises blazing-fast data transmission speeds.
The first 4G handset, Sprint’s HTC Evo, hits U.S. retail stores Friday, making this a good time to answer your questions about the fast wireless technology behind the Evo.
4G is just getting started, and even Sprint’s network is only available in a handful of cities. But in just about two years, 4G could be almost everywhere. All major U.S. wireless carriers are working on upgrading their systems to 4G — though we would prefer if some, like AT&T, got their 3G networks working properly in the meantime.
So what goodness will 4G bring to the world and should you hold your breath for it?"
Very good breakdown. Did a very good at explaining differences between LTE and WiMAX as well as the history of 3G networks.
