<< Domestically, however, why would SKT go with WCDMA? Seems illogical (and expensive) >>
I credit them with capability to be very logical, and they have the $ to invest. Any digital network is expensive, and has a long, long, payback. I suspect they have crunched the numbers.
And if you look at the network plan carefully, WCDMA is not simply being implemented for domestic reasons, and it takes into account all the developmental work that is going on in 3GPP, that is in turn being driven up over the top of the transom through OHG, and down into 3GPP2.
This is after all, leading to full scale multimedia services, on the worldwideweb.
Pretty sexy network plan here (and going forward through the next 4 slides), and doubt that it has changed too much at a high level too much, since this was published:
cdg.org
<< SK simply as a showpiece... Isn't that all it would be? >>
Not in my opinion (opinionated as I am) <g>.
I'll comment though on one element in the slides, that I have studied at some length.
The evolved IS-2000/IMT-2000 network shows a GSM-MAP component. It also shows a IMT-DS air interface (for global roaming). Theoretically, The IMT-DS air interface does not have to be UTRA FDD (WCDMA) DS. It could theoretcally be 3xRTT operating in DS mode on a 5MHz channel, and given the changes of the last several months maybe we throw in a little HDR (EV phase 1, 2, or 3) and ...
... we still have to wait a month to see if the haze is lifted.
