Eric,
<The current WCDMA proposal would yield about 6 percent greater spectral efficiency.>
He also states that:
While gaining paltry and diminishing returns in spectral efficiency, the wider spread incurs real and rising costs in
chip set complexity and handset power. Operating across a wider spectrum, a WCDMA rake receiver must
process three times as many signal elements in the 156 microseconds available, requiring more rake components,
each operating three times as fast. The result is more complex and expensive chips, more silicon area, more
power consumption, and ultimately, perhaps, lower performance.
I have yet to see figures that support that WCDMA will be as efficient as 1X, and is a cheaper implementation for a GSM carrier. Remember...1X doubles voice capacity.
Personally, I could give a rat's ass, as long as it isn't EDGE. I have heard a lot of economical arguments for both standards, but I've never seen anyone actually produce the numbers. It appears that the GSM carriers think WCDMA will be cheaper, but can they afford to wait around for WCDMA to mature? Increasingly, carriers are owning GSM and CDMA networks, so they may be agnostic to either flavors of CDMA right now, feeling the standards will merge sometime in the near future.
