Huawei announced the successful implementation of the GSM-LTE Dynamic Spectrum Sharing (GL DSS) trial with Vodafone Spain today. GL DSS is able to improve LTE capacity by up to 50% through maximizing wireless spectrum utilization, reports Huawei.

Several operators, including Vodafone, currently hold bandwidths of 20MHz at 1.8GHz, of which 10MHz is used for LTE and the rest for high GSM traffic. Huawei selected Vodafone’s Mobile Access Competence Center in Spain to jointly define this efficient spectrum management tool.

By applying interference scheduling in real time, the Huawei’s Single Radio Controller (SRC) gives GSM higher priority to use spectrum in periods of heavy traffic, providing protection against GSM voice interference, according to the company. This trial verified GL DSS performance in the Vodafone-Spain commercial network, with results showing that this solution can reach LTE capacity gains of up to 50%, making 15MHz effectively available for LTE with limited impact to GSM services.
