Re: One wonders about at&t...

The problem with UMTS/HSDPA is that it was designed for a European environment where spectrum auctions take into account which technologies must be deployed on them, while in the US spectrum is auctioned off in a less organized fashion and companies can use different technologies. The main reason CDMA EV-DO is better deployed is because it only requires 1.25Mhz channels (IIRC), though it only does data and not voice.

It was designed for a global environment, however, the U.S. does not always have the same spectrum availability as other countries do. Also, many companies prefer to cut costs where possible, while many other nations have spectrum mandate due to high government regulation of the wireless industry.

I agree that 1.25MHz channels are a nicer fit than the relatively huge 5MHz channels used by WCDMA/UMTS
