Fourth generation (4G) mobile systems are characterized by high-speed data rates between 20 to 100 Mbps, suitable for high-resolution video and television. Initial deployments were anticipated between 2006-2010. Some potential applications of 4G include virtual navigation, geographic information systems, telemedicine, and voice calls over the internet. Related research topics examined for 4G include orthogonal frequency division multiple access, multicarrier code division multiple access, software defined radio using field programmable gate arrays and digital signal processors, and multiple-input multiple-output antenna configurations.

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.
