  2. What is fourth generation (4G) mobile systems? Fourth generation mobile communications systems that are characterised by high-speed data rates at 20 to 100 Mbps, suitable for high-resolution movies and television, virtual . Initial deployments are anticipated in 2006-2010. 4G P. Yuvapoositanon Electronic Eng

  5. 3G 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. 4G P.
