I am working on a lecture at the University about this so could be very
to know what you think and include some comments:
From a KDDI press release:
Number of 3G Mobile Phone (CDMA2000 1x) Users Tops Ten Million
Tokyo, Japan (Sept. 17, 2003)—KDDI Corp. and Okinawa Cellular announced
recently that the total cumulative number of users for the
third-generation mobile phones (CDMA2000 1x) being offered by the two
companies has surpassed ten million on September 16. Sales of CDMA2000
1x au mobile phones began on April 1, 2002. The ten million mark was
surpassed less than eighteen months after the original release.
Currently, about two-thirds of all au mobile subscribers uses 3G mobile
On the DoCoMo side Foma has reached just one million users to date
- Is CDMA2000 1x a real 3G technology?
I do not see this as really important. With CDMA2000 1x (144kbps) you
as much rich information as available technology can handle in a useful
on a phone or handheld in a mobile context. You really need a laptop to
the advantage of 3g but then you also compete with Wi-FI.
- Can we consider DoCoMo Foma introduction a strategic flop still to be
Personally I think that introducing Foma without a dual-mode phone
of roaming in 2g was really a bold error. Also DoCoMo has underestimated
the real user experience (Size, Battery, software, services, costs etc)
was, by the end, much worse on the 3g Foma phones than their "old" 2g
Is quiet interesting to see that broadband 3g has been growing much
faster in Italy
with Three in Italy than in Japan with DoCoMo Foma. Is not Japan known
a more sensible market for new technology?
- Is there any interesting application for speed over 144kbs?
VideoCalls are not taking-off in Japan or EU and you can handle with
a quite limited bandwith . With an optimised 144kbs connection
you can have high quality Mpeg4 streaming video content. So it is very
to find a bandwith intensive application for an hand-held device based
These are really general problems about the transition form 2g to 3g
future of mobile communication.
