VoIP surpasses traditional telephony’s voice quality - High-definition technology from Infineon brings radio-quality sound to phones


Infineon Technologies, a leading provider of integrated electronic circuits for communication applications, has achieved a new milestone in voice over Internet Protocol (VoIP) voice quality. By integrating high-definition (HD) sound telephony into its VoIP products, Infineon has made it possible, for the first time, for users to enjoy audio in a quality far superior to that offered by conventional telephony. This HD technology delivers sound so crystal-clear and natural that users can conduct conversations in an audio quality on a par with radio.

Voice over IP has become a standard technology for businesses and end users. However, although highly innovative, VoIP’s inability to provide consistently high audio quality has been a weak point of the technology. With the HD sound telephony features incorporated into Infineon’s VoIP chip sets, service providers can now offer IP telephony-ready home gateways that deliver flawless audio quality.

“HD sound quality will take voice over IP’s usability a great step forward and encourage broader acceptance,” says Dominik Bilo, Vice President Sales and Group Marketing, Business Group Communication Solutions at Infineon. “We expect VoIP will increasingly displace traditional telephony worldwide and will find rapid take-up among customers, thanks to its better quality.”

Compared to traditional “narrowband” telephony, which works with a reduced acoustic bandwidth and represents a compromise between voice clarity and data rates, HD sound broadband technology uses a much wider transmission spectrum. The result is greatly improved, more natural sound, not just for voice calls but also for other audio applications like MP3 and internet radio, which makes for a much better user experience.
