Wi-Fi and cell phones

Martin Cooper, the father of the first cell phone call, has the following to say about Wi-Fi:

“”Wi-Fi is wonderful. It is a superb local area network–what it was designed to do–and it does that very well. When you try to make Wi-Fi cover a wide area, it’s absolutely the worst way to do it. Think about it. In order to cover a city, you need a million sites; we actually did an analysis of that. And every one of them has got to have backhaul. So it turns out it’s neither economical nor practical.” (via cnet)
