For comparison, imagine a cocktail party, where couples are talking to each other in a single room. The room represents the available bandwidth. In GSM, a speaker takes turns talking to a listener. The speaker talks for a short time and then stops to let another pair talk. There is never more than one speaker talking in the room, no one has to worry about two conversations mixing. In CDMA, any speaker can talk at any time; however each uses a different language. Each listener can only understand the language of their partner. As more and more couples talk, the background noise (representing the noise floor) gets louder, but because of the difference in languages, conversations do not mix.

The Three Gorges Dam in China, the largest hydro-electric power station in the world.
I dunno this before.. but I do remember the trip I went before this project was launched. A lot of places in Sichuan were buried (including the cool ghost city!) and I got the last chance to see them before they drown.
