FORNEBU, Norway -- Mobile sound quality is now upgraded to provide clearer sound quality during calls that filters out background noise. As of today, Telenor has become the only mobile operator in Norway to offer HD Voice across its network. "During the last few years, there has been a rapid development of mobile technology: we've got a faster network, smarter phones, and new services. Soon there won't be anything that you can't do with your mobile phone. But one area has been lagging behind. Sound quality during calls has not seen any significant improvements since the introduction of GSM in the early 90s," says Berit Svendsen, CEO of Telenor Norway. However, from today Telenor will be taking its customers on a journey of constantly improving sound quality. "Mobile phone conversations where it's difficult to understand what's being said can be very tiresome. We finally have the solution to meet this challenge and Telenor will be working to ensure that more and more people are able to enjoy the benefits of the mobile sound quality of the future," says Svendsen.
