With mobile data demand growing at an unprecedented pace, and a projected 2 billion HSPA/HSPA+ subscribers using WCDMA for voice services by 2015*, HSPA/HSPA+ operators must plan to evolve their voice services to WCDMA+.
Employing WCDMA+ is a cost-effective strategy for boosting network efficiency as it enables HSPA/HSPA+ operators to make voice even more efficient thereby freeing-up resources for more data.
WCDMA+ is an important component of Voice Evolution underway in the industry, and is expected to be part of 3GPP Rel. 12.

WCDMA+ Triples Voice Spectral Efficiency
WCDMA+ is the next evolutionary step for WCDMA. By incorporating innovative radio link enhancements and enhanced voice codec, WCDMA+ triples the voice spectral efficiency, freeing up resources worth up to 2/3rd of a 5MHz carrier for HSPA+ data.
More Data Capacity at All Voice Loads
WCDMA+ will provide higher data capacity for all voice loading conditions—low, medium or high— making it an excellent upgrade option for all network deployments.
WCDMA+ Ensures High Quality, Reliable and Ubiquitous Voice
WCDMA+ builds on proven WCDMA voice technology by continuing to incorporate features such as soft handovers to ensure high quality, reliable and ubiquitous service with global roaming.
WCDMA+ Addresses All Device Segments
WCDMA+ cost-effectively address all device segments. For lower-end devices, a single antenna is sufficient to provide up to 3x gain. High-end devices with dual receiver diversity and advanced receivers will deliver even higher performance.
