                  Mobile Wireless Market: Technology Forecasts
                  In the last few years the traffic increases in the mobile 
                  networks and the number of subscribers has been greater than 
                  anticipated. Infact in many places the mobile penetration has 
                  grown to more than 50%. In this section I'll talk about the 
                  existing market for the 2G technologies as well as forecasts 
                  for these technologies and the third generation networks.  
                  What looks clear is that after coexisting with the digital 
                  technologies for a few years (3-5) we'll see a disappearance 
                  of the analogue technologies. According to the latest updates 
                  from [2], the number of digital cellular subscribers is 
                  expected to double from around 624 million in early 2001 to 
                  over 1.14 billion at the beginning of 2003 and may move up to 
                  1.62 billion at the beginning of 2005. At the same time we'll 
                  see the number of analogue cellular subscriptions falling from 
                  80 million at the beginning of 2001 to 37 million by the 
                  beginning of 2003 and 14 million by the beginning of 2005. 
 
                  The current second generation technologies, thanks to the 
                  continuos improvements and 2.5G overlays should be viable in 
                  the medium term and continue to win market share for at least 
                  next five years. Also, the 3G technologies should not have any 
                  major impact till 2003 and then coexist with 2G technologies 
                  for another 2 to 3 years before gaining prominence. 3G related 
                  work is still going on and Japan could be among the very first 
                  countries with commercial 3G roll out, as early as 2002. The 
                  next graphic shows a distribution of cellular subscribers 
                  across various regions of the world and the forecasts for 
                  future.  
                  
                     
                  
                  
                  According to the coverage and the subscriber numbers world 
                  wide, GSM comes out as a clear winner in digital technologies. 
                  Today 89% of all cellular subscribers are using digital 
                  technology and around 65% of these are GSM subscribers, with 
                  CDMA and D-AMPS having around 13-14 % of digital subscribers 
                  each.  
                  As the number of digital subscribers grows by almost 100 % 
                  by 2003 the subscriber ratio is expected to remain the same. 
                  3G should begin showing it's presence but with a very small 
                  number of subscribers till 2003 and a subscriber base of under 
                  2.5% till 2005.
