Scenarios about 4G technology standard and 2010-2015 Forecast
Mobile communication technology has been constantly evolving from analog mobile communication (1G) through digital technology 2G (e.g. GSM), to 3G with enhanced data communication capability. Accordingly, the number of mobile communication subscribers has been increasing rapidly (Fig1).
Yet, there is little consensus for next generation 4G technology. According to ITU (International Telecommunication Union), 4G technology should provide IP based 100Mbps~1Gbps connection.
There are 2 groups running for 4G standard. Each group wants to lead 4G to one’s favorable direction; thereupon each group started a standard war.
