I see this values repeated over and over as a "paradise" promise for end-user.I think that's one misunderstanding: 100mb DL_speed is the Base_Station total capacity - what operator have available for end-users -, not the DL_speed of one particular user. Most probably you'll get 2mb at one affordable price. Even so, I won't trade my home optical fiber connection(100mb guaranteed) for 2mb on radio(best-effort, at best!) I have very few applis for mobile usage. As about 10mb DL_speed for Spring it's accordingly with the standard(TDD, 5MHz BW). In WiMax2 standard these speeds grows up to 100Mb
