We remember when WiMAX was just a twinkle in a wireless engineer's eye, and now it's all ready for the big time, as the ITU officially approved the spec as part of the 3G standard today. That's doubly special since WiMAX is the first non-cellular tech to get approval as 3G, but with services like Sprint's Xohm blurring the line for consumers, we can see how it's easier to just lump it all together. Of course, Sprint confusingly says Xohm is "4G," but it looks like they may need to tone it down now that the ITU has spoken. Either way, the ITU's decisions usually get enacted by governments, which means carriers with 3G spectrum will soon be able to start building out WiMAX networks without additional regulations. It's so bittersweet when they grow up, isn't it?
