Qualcomm Unveils New Voice Protocol
Oy.
This sounds good, don't get me wrong. Developing our software better to get the most out of older hardware is a great strive for modern technology--the tendancy to abandon older technology is more our style (AMPS > TDMA > GSM, need I say more?).
However, forgive me if I seem ignorant, but isn't the 4G Qualcomm codec going to be deployed on newer handsets, making older handsets unable to take advantage of the new software? Or are there software updates in the works?

I agree, however wireless carriers have grown significantly from when the switch from TDMA to CDMA took place. The coverage area that would be affected is much larger than it used to be. That's why companies like Verizon and Alltel will for surely hold on to CDMA until it's last dying breath. It's great to see an improvement on a system that is established instead of a new system that has lots of holes and isn't solidified (Cingular).

What system are you talking about? Cingular has switched to the most common, "solidified" system in the world (GSM) and are headed towards 3G (umts/hsdpa) rather quickly.
...
Most commmon in the world yes. But in the U.S. CDMA has more coverage in rural areas along with major cities. GSM coverage in many areas ie: wisconsin and minnesota there are many areas that CDMA will work and GSM will not. GSM has a lot of groing in rural areas before it even comes close to CDMA. That's why I'm excited we are making CDMA even better because GSM is going to take 3-5 years before it gets close to CDMA.
...
The rural areas you speak of are generally covered by analog. When you compare digital it is generally the same coverage for both companies. Give or take some areas where one will out perform the other.
...
Not that I care one way or the other - but it is true that GSM in the US does not have a complete overlay of where all of the rural carriers have AMPS - especially the mid-west and the west. I do think that Verizon is cutting back on its abilities for easy AMPS roaming with new plans, as the day will come where carriers will reclaim AMPS spectrum. Many newer CDMA phones do not have AMPS features anymore.
...
just another NON SENSE, GUY THAT THINKS GSM IS THE BEST TECHNOLOGY. HAHAH, DON'T MAKE ME LAUGH
CDMA WILL BE THE BEST TECNOLOGY FOR QUITE MORE TIME
LITLLE GUY..

THEY ARE HEADING towards 3G (umts/hsdpa) rather quickly.,, WELL YEAH IN 12 MORE MONTHS, NOT THAT QUICKLY AS YOU SAY
WHILE VERIZON IS ALREADY OPERATING IN 3G CDMA.
SUCH A LOOSERS (CINGULAR)

Correct. Network upgrades will be deployed, and only new handsets made after 2006 will support the new mode.
This is how it always works with pretty much any new technology in this industry. It was the same with the EVRC codec, and with the deployment of 1xRTT.
But as with those and most CDMA improvements, it's all backward-compatible, so old phones will continue to operate on upgraded networks just as they did before. Things like capacity improvements will simply be realized over time as more people get new handsets through natural upgrades.
...
I just hope they don't degrade sound quality more...... I don't want to sound like/listen to a robot 😁
...
With the improvements in compression algorithms since EVRC came out, there is no reason to decrease voice quality.
After travelling to many counries and using digital networks, I believe that the CODEC is only one factor (and a minor one) in voice quality. The handsets' amplifiers and speakers have a lot to do with voice quality. System congestion is a major factor in voice quality.
The CODEC used in TDMA (IS-136) is, IMHO, pretty awful. I do not find much of a voice quality difference between the current GSM and CDMA CODECs.
