3G Realities3G Realities A recent study by Herschel Shosteck Associates noted that

operators that pay large amounts for spectrum will have to charge end users so much that adoption of 3G will be slow.

Another study by Strategy Analytics agreed, predicting that, while wireless data revenues will soar, 3G networks will account for less than a quarter of that revenue by 2010. So-called 3G killer apps such as multimedia won't succeed, the second study said.

Pent-up demand: Now there's the rub. Even NTT DoCoMo doesn't think there's much pent-up demand among consumers for 3G multimedia services, so it will target its initial 3G offering at business -- and price it accordingly.
