DMB – Digital Multimedia Broadcasting – is now being watched by over a million Koreans since its launch last year. DMB lets you watch several dozen channels of TV content on your phone.
4G networks are in trials and demonstrations. They provie 100 megabit stream of data whilst moving at 60 kph and 1 gigabit while stationary.
