Nokia Siemens Networks has announced that it has doubled the capacity of the GSM network within existing spectrum, giving GSM operators across the globe more network to offer, as well as better quality.
Nokia Siemens achieved this upgrade to capacity via its Dynamic Frequency and Channel Allocation (DFCA) feature, which supports additional network growth while not impacting upon service quality or even control costs.
It was revealed that emerging markets see millions of additional GSM subscribers every month, but spectrum limitations have hampered this growth and required the building of more base station sites, which simply increases costs across the board. With DFCA, however, these problems are significantly eased.
“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 at Nokia Siemens. “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.”
The new DFCA feature also has the potential to improve the overall network quality, which means that existing customers on the GSM network may also benefit from this technology. If that were not enough, the feature also lowers energy costs per subscriber, which means that almost overnight GSM will become larger, have better quality, and will be more energy efficient.
