Hey, at around 14:00 you mention that China Mobile supported TD-SCDMA, which is based on Time Division Duplexing. Is TDD always narrowband? ANd likewise is Frequency Division Duplexing (FDD) always wideband? Why would they actively want TDD then? What is the advantage of TDD over FDD and vice versa?

The normal 3G TDD is 5MHz wideband, like FDD but nobody deployed it. China wanted their own standard hence they developed narrowband TDD which is TD-SCDMA. I have couple of old blog posts on this topic you will enjoy. They should answer your questions too. blog.3g4g.co.uk/2009/09/td-scdma-tdd-and-fdd.html and blog.3g4g.co.uk/2010/01/technologies-and-standards-for-td-scdma.html
