Does nobody have no opinions? 4G it's fourth generation of GSM. 4G technology stands to be the future standard of wireless devices. The Japanese company NTT DoCoMo is testing 4G communication at 100 Mbit/s while moving, and 1 Gbit/s while stationary. NTT DoCoMo plans on releasing the first commercial network in 2010. In general, a generation is defined by the result of technology changes over a 10-15 year time frame. Thus, 4G would refer to whatever is deployed in the 2010-2015 period, assuming 3G deployment spans the 2000-2009 period. However, 3G is regarded by many as being a bit of a 'flop', so telecommunications companies are planning to roll out 4G earlier (possibly as early as 2008). The Chancellor of the Exchequer in the United Kingdom will auction 4G frequencies in autumn 2006. What do you think about that domain?
