It seems that getting truth through hype is ever so difficult. The
truth of the matter is that in terms of spectral efficiency, the 3G
WDCMA (HSPA+ or equivalent cdma2000 EV-DO schemes) and 4G LTE are no
different. So if you aggregate WCDMA channels together to achieve
the same channel bandwidths as LTE, you will achieve the same bit
rates.

The larger appeal of LTE is that we may finally move to a common
infrastructure for wireless that can be exploited by all carriers.
CDMA and GSM voice services will eventually be replaced with IP
telephony over the 4G networks. Investing more in a CDMA based data
network only exacerbates the problems we have in this country with
competing standards...
But WCDMA is likely to see some deployments until things start to converge.
