The Fraunhofer-Gesellschaft has a audio technology revealed that the sound quality of a call via a lte connection should improve. With a proprietary codec, among others, the frequency range is incremented.
According to the German research institute phone calls are generally limited to a maximum frequency of 3.5 KHz, that by some providers is incremented to 7KHz. People can, however, frequencies up to approximately 20KHz to hear. The Fraunhofer-Gesellschaft claims that its new audio technology, Full-HD Voice is called, the entire spectrum of perceptible frequencies, making the sound quality of the call improves. This uses the proprietary codec aac-eld.
It is not the first initiative that is launched to the call quality for phones to improve. Previously announced that KPN that the HD Voice wants to implement on his network. This technique is, however, not limited to lte networks. There is by the Fraunhofer-Gesellschaft is a demo released that the differences between a Full-HD Voice, HD Voice, and a conventional connection demonstrates.
The German institute is also planning to during the upcoming Mobile World Congress in Barcelona, the newly-introduced audio engineering to demonstrate. It will, therefore, make use of an Android smartphone that has the necessary audio codec supports. It is still unknown which models directly can be used for Full-HD Voice.
Currently, in the Netherlands there is still no lte connections provided to consumers. The expectation is that the roll-out until sometime next year is about to begin. Or the by the Fraunhofer-Gesellschaft has developed audio technology also is implemented, remains to be seen.
