ZTE Corp. unveils its completion of CDMA2000 1x Advanced IOT testing in partnership with Qualcomm Inc., which advances the commercial availability of the technology. When fully implemented, a CDMA2000 1x Advanced network will quadruple voice capacity while ensuring excellent HD voice quality.

The successful tests demonstrate that ZTE's CDMA2000 1x Advanced equipment are fully compliant with industry standards and requirements. This follows ZTE's earlier breakthrough in carrying out the world's first successfully CDMA2000 1x Advanced call in November 2010.

A series of comprehensive tests were performed to measure voice, data and SMS compatibility between the terminals of existing networks with a 1x Advanced network and terminals. In terms of the 1x Advanced features, the testing covered EVRC-NW (Enhanced Variable Rate CodecNarrowband-Wideband) and wireless link advanced verification. In addition, soft handover, hard handover and network co-existence were also tested.

The CDMA2000 1x Advanced technology incorporates a range of technologies such as Interference Cancellation, Mobile Receive Diversity and Radio Link Enhancements (including Smart Blanking, Efficient Power Control, Frame Early Termination and Quasi Orthogonal Function).

To fully protect existing investments into CDMA2000 1x Advance technology, network operators need only to replace their existing 1x channel cards. This design was made to maximize network revenue and minimize upgrading costs.
