HD Voice – a Revolution in Voice Communication HD Voice – a revolution in voice communication Besides data capacity and coverage, which are one of the most important factors related to customers’ satisfaction in mobile telephony nowadays, we must not forget about the intrinsic characteristic of the mobile communication – the Voice. Ever since the nineties and the introduction of GSM there have not been much improvements in the area of voice communication and quality of sound has not seen any major changes. Smart Network going forward! Mobile phones made such a progress in recent years that they have almost replaced PCs, but their basic function, voice calls, is still irreplaceable and vital in mobile communication and it has to be seamless. In order to grow our customer satisfaction and expand our service portfolio, Smart Network engineers of Telenor Serbia have enabled HD Voice by introducing new network features and transitioning voice communication to all IP network. This transition delivers crystal-clear communication between the two parties greatly enhancing customer experience during voice communication over smartphones. Enough with the yelling into smartphones! HD Voice (or High-Definition Voice) represents a significant upgrade to sound quality in mobile communications. Thanks to this feature users experience clarity, smoothly reduced background noise and a feeling that the person they are talking to is standing right next to them or of "being in the same room" with the person on the other end of the phone line. On the more technical side, “HD Voice is essentially wideband audio technology, something that long has been used for conference calling and VoIP apps. Instead of limiting a call frequency to between 300 Hz and 3.4 kHz, a wideband audio call transmits at a range of 50 Hz to 7 kHz, or higher. That’s much more in line with the human voice, which transmits audio between 75 Hz and 14 kHz. HD Voice also takes in more audio samples per second than a standard call. Instead of 8,000 audio samples per second in standard calls, HD Voice calls double that to 16,000. That way, a person is able to hear more details in the voice during a call” (taken from www.wired.com). This is a serious step in the evolution of audio clarity and quality for telephony systems, one which can lead to greater customer satisfaction, as well as revenue opportunities for Telenor Serbia. In order to enable this service, both interlocutors must have devices supporting HD Voice. Ingeborg Ofsthus, Telenor Montenegro and Telenor Serbia CTO, would like to thank the teams in Technology and Telenor Common Operations who have been responsible for the successful implementation of this important project. “Evolution of our network to all-IP infrastructure and advanced network features were at the same time the opportunity for technology engineers to learn latest technology developments and the challenge to utilize them and improve our network quality”, says Ofsthus. “In addition, the implementation of similar feature is ongoing in Montenegro, and is another example of cooperation between the experts in the Common Organization – Telenor Montenegro and Telenor Serbia. I believe that HD voice will strengthen our technology leadership position and further increase value for our customers and their satisfaction,” Ofsthus concludes. This service is available in the entire Smart Network (GSM and 3G) and it is free-of-charge. Currently this service is supported by certain smartphone models in Telenor’s portfolio such as: HTC Desire X, HTC Telenor Group is one of the world's major mobile operators.

An Internet-based service can be maintained at a fraction of the cost of a phone network and helps Verizon offer a greater range of services, Stratton said.

  • Shaping Our Financial Future Socio-Economic Impact of Mobile Financial Services
    Shaping our financial future Socio-economic impact of mobile financial services 1 Growth comes from truly understanding the needs of people, to drive relevant change 2 Foreword It is my pleasure to introduce you to our most recent study on the socio-economic impact of mobile financial services, conducted with the help of Boston Consulting Group (BCG). Through our research, we looked at what mobile financial services will mean to the world in the year 2020. We specifically delved into five countries: Pakistan, Malaysia, Bangladesh, India and Serbia, all markets in which Telenor Group has mobile operations. Without giving away too much of what lies ahead, I can firmly say that mobile financial services will have a significant impact on the economic and societal growth of the countries studied. By bringing banking services and financial products to people who are entirely unbanked at present, they now have the chance to strengthen their development and prosper. The mobile phone is the key to simpler money transfers, readily accessible savings accounts, new methods of bill payment and even insurance products to protect against unforeseen events. This is the first comprehensive study to truly identify the impact of mobile financial services over the next decade. It helps us understand how the introduction of these services can create more jobs in Pakistan, bring insurance to more people in India and increase Serbia’s GDP. While the results of our study are not absolute, they give an indication of what is possible with the appropriate regulatory framework and governmental support. As a global telecommunications operator, we have a unique role to play in the development and expansion of mobile financial services.

  • The Growing Importance of HD Voice in Applications the Growing Importance of HD Voice in Applications White Paper
    White Paper The Growing Importance of HD Voice in Applications The Growing Importance of HD Voice in Applications White Paper Executive Summary A new excitement has entered the voice communications industry with the advent of wideband audio, commonly known as High Definition Voice (HD Voice). Although enterprises have gradually been moving to HD VoIP within their own networks, these networks have traditionally remained “islands” of HD because interoperability with other networks that also supported HD Voice has been difficult. With the introduction of HD Voice on mobile networks, which has been launched on numerous commercial mobile networks and many wireline VoIP networks worldwide, consumers can finally experience this new technology firsthand. Verizon, AT&T, T-Mobile, Deutsche Telekom, Orange and other mobile operators now offer HD Voice as a standard feature. Because mobile users tend to adopt new technology rapidly, replacing their mobile devices seemingly as fast as the newest models are released, and because landline VoIP speech is typically done via a headset, the growth of HD Voice continues to be high and in turn, the need for HD- capable applications will further accelerate. This white paper provides an introduction to HD Voice and discusses its current adoption rate and future potential, including use case examples which paint a picture that HD Voice upgrades to network infrastructure and applications will be seen as important, and perhaps as a necessity to many. 2 The Growing Importance of HD Voice in Applications White Paper Table of Contents What Is HD Voice? . 4 Where is HD Voice Being Deployed? . 4 Use Case Examples .
