Qualcomm Unveils New Voice Protocol

May 6, 2005, 11:54 AM by (staff)

Qualcomm this week announced 4GV (Fourth-Generation Vocoder,) a new codec for compressing and transmitting voice over CDMA networks. The flexible protocol can be deployed over 1xRTT networks, or 1xEV-DO networks using VoIP technology. 4GV is up to 40% more efficient than the current EVRC codec. Carriers will have the option of using the added efficiency to improve either network capacity or voice quality. Technology trials of 4GV are expected in the second half of 2005, with commercialization as early as 2006.

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 hol...
