Licensing and Guidelines
Using the HD Voice+ logo
The GMSA HD Voice and HD Voice+ logo licensing program enables a uniform industry message on the enhanced voice quality of terminals and networks featuring super-wideband voice communication. HD Voice and HD Voice+ offer twice the audio frequency bandwidth of HD Voice and HD Voice+, made possible through the use of 3GPP’s Enhanced Voice Services (EVS) codec. Improved voice quality, better resiliency to adverse network conditions, better intelligibility, and improved network capacity can be expected with the new system. GSMA HD Voice+ licensing program requires compliance to minimum performance requirements, including proper interoperability with existing HD Voice and HD Voice+ systems.
