SHENZHEN, China -- Huawei, a leading global information and communications technology (ICT) solutions provider, today announced the successful implementation of the world’s first GSM-LTE Dynamic Spectrum Sharing (GL DSS) trial with Vodafone Spain. GL DSS is able to improve LTE capacity by up to 50% through maximizing wireless spectrum utilization. This trial represents a major milestone in the innovation of Huawei’s Single Radio Controller (SRC) that was released in 2013. Competition is fierce for LTE spectrum resources globally, especially for bandwidths including 1.8GHz. 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 and, at the same time, continue to provide the best user experience.

Huawei’s SRC brings flexibility to spectrum resource allocation by introducing GL DSS. By applying interference scheduling in real time, the SRC gives GSM higher priority to use spectrum in periods of heavy traffic, providing protection against GSM voice interference. SRC also provides more spectrum for LTE compared to the standard fixed configuration through dynamic allocation; allowing for better LTE throughput. 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.

A CSP's digital transformation involves so much more than technology. Crucial – and often most challenging – is the cultural transformation that goes along with it. As Sigma's Chief Technology Officer, Catherine Michel has extensive experience with technology as she leads the company's entire product portfolio and strategy. But she's also no stranger to merging technology and culture, having taken a company — Tribold — from inception to acquisition (by Sigma in 2013), and she continues to advise service providers on how to drive their own transformations. This impressive female leader and vocal advocate for other women in the industry will join Women in Comms for a live radio show to discuss all things digital transformation, including the cultural transformation that goes along with it.
