"W"CDMA is not same as CDMA.

W-CDMA (Wideband Code Division Multiple Access) is a type of 3G cellular network. W-CDMA is the technology behind the 3G UMTS standard and is allied with the 2G GSM standard.

More technically, W-CDMA is a wideband spread-spectrum 3G mobile telecommunication air interface that utilizes code division multiple access (or CDMA the general multiplexing scheme, not to be confused with CDMA the standard).

My understanding is, existing CDMA will migrate to EV-DO while GSM providers will migrate to W-CDMA/UMTS.

I think people are getting confused of CDMA and WCDMA!

Still TRAI is mulling on spectrum policy. So I do not consider this rumor as credible.

@ Ni****h: Please browse through the link I posted above to know how different is WCDMA from CDMA.

If Reliance will upgrade it will to EV-DO and not WCDMA. WCDMA is a upgrade path for GSM, though it shares the name with CDMA. I repeat CDMA in WCDMA stands for "CDMA - the general multiplexing scheme" and not the "CDMA Standard" that Reliance follows.
