Telecommunications equipment and network offerings provider ZTE has announced that it has successfully completed CDMA2000 1x Advanced call based on CDMA2000 1x system.
The call features a four-fold increase in voice capacity and follows the specifications of CDMA2000 1x Advanced technology published by Third Generation Partnership Project 2 (3GPP2).
The CDMA2000 1x Advanced technology incorporates multi-technologies such as the 4th generation Vocoder (4GV), interference cancellation, mobile receive diversity and radio link enhancements (including smart blanking, efficient power control, frame early termination and quasi orthogonal function), to quadruple the voice capacity.
ZTE CDMA & LTE product line general manager Li Jian said CDMA2000 1x Advanced technology can greatly improve frequency efficiency by helping the operators re-form frequency resources, develop voice and data services as needed and adopt more flexible business models.
"All CDMA2000 operators can benefit from the increased voice capacity, expanded coverage and improved voice quality brought by the 1x Advanced technology," Jian said.
