NSN conducts Dual Full Rate call using latest software innovation

Nokia Siemens Networks (NSN) has 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 enjoy the twin benefits of up to 100% increase in voice capacity and significantly enhanced speech quality. GSM is by far the most widespread mobile technology with over 4 billion subscriptions worldwide.

Kimmo Virkki, Head of GSM product management, Nokia Siemens Networks, said, "OSC-DFR can reduce capital and operations expenditure for operators as it requires fewer carrier units and base station sites as well as less transport capacity. Moreover, the OSC-DFR feature allows operators to accommodate more voice and data traffic into the existing spectrum, thus facilitating the reuse or reframing of 3G/LTE services in GSM frequency bands."

Operators who have deployed the commonly used Adaptive Multi Rate-Full Rate (AMR FR) 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.
