CDMA2000 1x Advanced tested by ZTE
CDMA2000 1x Advanced is utilizes new technologies like 4th-Gen Vocoder, Interference Cancellation, and Mobile Receive Diversity/Radio Link Enhancements, all of which add up to a more efficient CDMA system as well as improved call quality.
Li Jian of ZTE assured customers and carriers that their existing CDMA systems will be preserved: "The existing investment can be protected to the maximum, as only the 1x channel card needs to be replaced."
Aside from voice calls CDMA2000 1x Advanced could also free up space for improved data services. It is unlikely, however, as Verizon and Sprint both have 4G services that would make a new CDMA data stream redundant.
ZTE has announced that they will debut the CDMA2000 1x Advanced in the first quarter of 2011. This move will likely further improve their position as the largest CDMA equipment provider.
Below is a video from Qualcomm, explaining how the new CDMA technology could affect networks, and what types of equipment options will be available to carriers.
