Enterprises are rapidly incorporating Internet Protocol (IP) based unified communications services with their business process in order to take advantage of efficiencies of voice and data convergence, flexibility, and a rich set of features that only IP can deliver. Converged networks are the reality in enterprise communications with vast potential for new applications and services. However, as the communications technologies evolve, and more Unified Communications components emerge, IP Telephony continues to be the foundation for enterprise communications as the sound of the human voice is the single most powerful component that unifies and clarifies all other forms of communications. Yet, since the invention of the telephone there have been few enhancements in the sound quality of a telephone call - until now.
Broadcore's IP-based infrastructure coupled with Polycom IP telephones deliver High Definition (HD) voice using a wideband technology to deliver a deeper clarity and better audio experience. HD Voice represents the next wave in IP telephony, showing customers that Voice over Internet Protocol (VoIP) quality can be vastly superior to that of traditional public telephone network. VoIP provides a new network dynamic to deliver a broader spectrum for voice communication and dramatically improve the user experience.
Two-thirds of the frequencies in which the human ear is most sensitive to, and 80 percent of the frequencies in which speech occurs, are beyond the capabilities of the traditional public telephone network. HD voice uses a wideband codec that doubles the sampling rate and more than doubles the width of the sound spectrum reproduced. To further enrich the user experience, Polycom phones incorporate next generation technologies for transparent full duplex, echo cancellation, dynamic noise reduction, automatic gain control, and microphone management. This further adds to unrivaled clarity and richness to the transmitted sound.
Superior HD voice quality is an added bonus for enterprise customers who turn to IP communications for flexibility, expanded integration options, and long-term cost saving opportunities. By doubling the clarity of ordinary phone calls, HD Voice allows users to enjoy life-like conversations with significant depth and nuance.
Technical facts
Traditional telephony is based on sampling the sound stream 8,000 times a second, thus constraining the reproduction of the sound spectrum to the range between 200Hz on the low end and to 3.3KHz on the high end. With HD voice, a wideband codec doubles the sampling rate and more than doubles the width of the sound spectrum reproduced, from 50 Hz to 7KHz.
