.....What will the data rates be for 4G (broadband mobile) in Japan?
At present (2G) imode data rates in Japan are up to 9.6 kbit/sec, but usually a lot slower, and 28.2kbps for 504i, 505i, 506i handsets (since May 2002). For 3G (FOMA) data rates are at present around 200kbps (download) and 64kbps (upload) and will in the future be upgraded to 10 Mbit/sec. KDDI/AU offers 2.4 Mbit/s since December 2003. For 4G data rates up to 20 Megabytes per second are planned. This is about 2000 times faster than present (year 2001) mobile data rates, and about 10 times faster than top transmission rates planned in the final build out of 3G broadband mobile. It is about 10-20 times faster than standard ASDL services, which are being introduced for internet connections over traditional copper cables at this time (2001).....
