Mobile HD Voice service using AMR Wideband Mobile HD Voice based on AMR (Adaptive Multi Rate) Wideband technology (W-AMR) enables high-quality voice calls in mobile networks and an improved user experience.

Comparative codec bandwidth envelopes
The maximum benefits from using HD Voice on a compatible mobile network are realized or perceived when both calling and called party use HD Voice-capable phones. Improvements in call quality are also observed even when calling a non-HD Voice phone, due to improvements in the acoustic performance and advanced noise reduction capabilities present in most HD Voice phones.

Mobile HD Voice: Global Update report
Mobile HD Voice commercial launches (GSA – June 3, 2011)
HD Voice trials and network deployments (GSA – June 3, 2011)
According to the results of a survey* by Orange:
96% of customers are satisfied with HD Voice calls
86% of testers say that compatibility with HD voice would be a selection criterion when purchasing a mobile in the future
76% of testers would be prepared to change mobiles to obtain HD Voice
Verizon Wireless demonstrated a range of Voice over LTE (VoLTE) and HD Voice capable user devices at Mobile World Congress 2011. “The initial devices we’ll support [AMR-WB] are smart phones for sure,” said Verizon Wireless Marjorie Hsu, VP Technology Development. “Other devices on the road map, we’re working through the form factor, we want to get the user experience right.” (Reported March 4, 2011: www.hdvoicenews.com)
Network aspects
Ordinarily the voice payload for transport in the core network is PCM-coded at 64 kbit/s according to ITU-T Rec. G.711. Narrowband AMR is transcoded to/from PCM which degrades voice quality, adding signal processing complexity. Analog PCM-based transport cannot be used with W-AMR as G.711 only applies to narrowband voice. W-AMR must be based on one of two complementary 3GPP standards: tandem-free operation (TFO) or transcoder-free operation (TrFO).
Introduction of W-AMR into GSM systems requires TFO, which is part of 3GPP GERAN, which does not require substantial modification of the core network. W-AMR and TFO can also be introduced into UMTS. A better option however, is to use the recommended TrFO. The combination of TFO and TrFO enables W-AMR calls between all types of 3GPP mobile devices (i.e. GSM/EDGE and UMTS/WCDMA-HSPA).
HD Voice ecosystem: wide choice of compatible phones
The mobile HD Voice eco-system is rapidly establishing. Alcatel, HTC, LG, Nokia, Samsung, and Sony Ericsson have launched HD Voice-compatible phones. A commitment to produce chipsets supporting HD Voice has also been confirmed by leading semiconductor companies.
