Taking a step forward in the evolution of GSM, Nokia Siemens Networks conducted the world’s first pre-commercial call, exploiting its Orthogonal Sub-Channel Dual Full Rate (OSC-DFR) software feature for GSM networks.
With this feature, GSM operators can now enjoy the twin benefits of up to 100% increase in voice capacity and significantly enhanced speech quality.
Operators who have deployed the commonly used Adaptive Multi Rate-Full Rate in their networks can use the OSC-DFR feature to achieve unmatched speech quality and at the same time can nearly double their voice capacity.
Nokia Siemens Networks’ new GSM feature will be used in customer pilots from the end of June 2011.
