HD Voice based on the AMR (Adaptive Multi Rate) Wideband technology (W-AMR) enables high-quality voice calls in mobile networks and an improved user experience. It provides significantly higher voice quality for calls between mobile phones supporting the feature, and can be implemented in GSM, WCDMA-UMTS, and LTE networks. The higher voice quality of HD Voice improves the call experience and allows people to better share feelings, do business and communicate information. HD Voice can help mobile operators to clearly differentiate their offerings and can enable high quality services to voice dependent business like call center services, information services, emergency services etc.
This updated report from GSA outlines the opportunities and benefits of deploying HD Voice service, provides an update overview on the accelerating number of network deployment commitments and service launches globally on GSM, 3G/HSPA and LTE networks (to July 10, 2013), and confirms the wide range of HD Voice-capable phones which are available.
