Does SprintPCS use 3G or 2.5G technology in the network? If SprintPCS is
using CDMA 1xRTT, it is 2.5G. When will we get 3G in the network?

More about : 3g

In Japan the European press calls 1xRTT 3G but the same press doesn't
call it 3G when it's in the Americas (go figure) .

The only technology that's commercially deployed that meets the 2 mbps
peak data rate spec is EV-DO (not the commercially rolled out W-CDMA).
EV-DO is coming to Sprint PCS.

The Sprint PCS announcement for EV-DO was made more than a month ago.

See one of the press reports here:

"Sprint hopes to launch its new service on a limited basis later this
year and in metro markets next year."

How do we compare EV-DO with UMTS? I think W-CDMA in UMTS will be better
than CDMA EV-DO.

For the user the average throughput of EV-DO will be 150-200% of
W-CDMA.

For the carrier there's a huge difference. EV-DO requires 1/4 the
bandwidth of W-CDMA. (Hence the interest in Flarion's OFDM for GSM
carriers, which also only requires 1/4 the bandwidth of W-CDMA.)

The wide band CDMA in W-CDMA can't have a better throughput than EV-DO. This
will make no sence to have the wide band for the W-CDMA. Why don't they put
a better coding in UMTS W-CDMA?
