Nokia Siemens Networks launched DFCA feature that can double GSMnetwork capacity

Nokia Siemens Networks has launched a unique Dynamic Frequency and Channel Allocation (DFCA) feature that can double GSM network capacity within existing spectrum. The feature supports growth, while maintaining service quality and controlling costs. GSM operators in emerging markets are adding millions of subscribers every month. However, spectrum limitations prevent operators from adding new subscribers to their existing networks without building more base stations sites.

“DFCA has immense potential to help operators address the challenge of ever increasing voice and data traffic,” said Prashant Agnihotri, head of GSM/EDGE product management, Nokia Siemens Networks. “It helps operators squeeze voice calls into less bandwidth, so it can be alternatively used for data, either through Enhanced Data Rates for GSM Evolution (EDGE) or by re-farming the spectrum to Wideband Code Division Multiple Access/Long Term Evolution (WCDMA/LTE). It brings a substantial increase for operators in terms of potential earnings per base station site.”

Nokia Siemens Networks’ DFCA feature helps operators to continue acquiring new subscribers while overcoming current spectrum bottlenecks. Using a combination of software features, it increases the traffic carrying capacity of existing sites, while improving network quality. This, in turn, minimizes the immediate investment in additional sites, reducing the total cost of ownership. An added benefit is a huge increase in energy efficiency per subscriber.
