The number of wireless mobile communication service subscribers reached 4.6 billion worldwide in 2009, and mobile revenues are expected to be over US$1 trillion around 2012 according to the International Telecommunication Union (ITU). A significant number of studies have been made to forecast the growing market and evaluate the new generation technology, the ‘beyond 3rd generation’ (B3G). However, there is no study that forecasts when any of these new technologies will be commercialised. This paper presents a technical framework for forecasting the commercialisation timeline of B3G technologies and provides insight on technology trajectories from 1G to 4G. The results show that a combination of technical parameters can explain heterogeneous wireless mobile communication technologies. Three parameters selected include channel bandwidth, channel bit rate and data capacity for technical framework.
