By contrast, NTTDoCoMo is putting its money firmly behind mobile data. Its investment plans in Japan provide capacity for huge amounts of data transmission. Three years from now, NTTDoCoMo will have invested, it says, 1 trillion yen (10bn Euros, if our maths is correct) in obtaining 6 million 3G customers. This investment, it says, will be enough to handle over 15m subscribers and provide coverage of 97% of the population. The major services it mentions as needing 3G bandwidth are music downloads and 'image clipping'.
