What would make the difference between J-Phone and Docomos FOMA? They are
both based on W-CDMA, the Docomo being a bit prestandard, but a network
update should put the system in line (I am sure they thought about that
one).
Currently they are the only one with a launched network,...(being limited in
coverage), but the wealth this provides in terms of management and control
of3G networks is enormous.
Vodafone will have to go through the same learning curve as Docomos using a
multivendor environment. Inevitably they will run into problems (as new
technology always does).
Too me, it doesnt make sense to say why Jphone will beat Foma, as Docomo
doeshave the first mover advantage and looking at any network rollout (GSM,
...), if they can keep up the pace they should be able to craft themselves a
very nice sweet spot in the 3G world.

And FOMA will, eventually, allow them to provide a wide range of services.

Can DoCoMo have both a successful FOMA and PDC service?
Why should DoCoMo promote FOMA when the 504s and i-shots phones are
selling so well?
the sales of 504i was a disaster, probably because of competition
from the 251i series (i-shot). while i-shot phones sell well, that's
more because the depressed need for camera phones DoCoMo had failed
to provide. and why the SH251i, the lowest spec camera phone from
a new comer (Sharp's first phone for DoCoMo) out sold 504i phones is
simply because people really wanted J-Phone Sha-Mail, but found out
later i-shot is a fake, far less usable (and expensive).
well, about FOMA, it doesn't look well and it seams will lose to
J-Phone IMT next year when Vodafone quickly expands its network and
provide much superior data service (OMA?) next summer-autumn.
but I heard that the 505i series (due next spring/summer) will come with a
UIM card, that may pave the way for an easier transition.
anyone (Gemplus, AU-Sys?) know about it? maybe we should discuss
in another thread, what will be these cards look l ike for each
Japanese operators? especially DoCoMo and au/KDDI?
btw, about UMTS, I'd rather call it 2.xG and its 5-20 MHz band means
low efficiency to me.
cheers,
Ken
