Ericsson a record download speed of 5.7Gbps for the world’s first 6CC (component carrier) data call.
The data call was achieved using three FDD (frequency division duplex) bands combined with three TDD (time division duplex) bands in sub-6GHz, enabled by Ericsson RAN Compute hardware, state-of the-art carrier aggregation software, and innovative Advanced RAN Coordination functionality.
The 3FDD + 3TDD carrier aggregation testing was carried out in an Ericsson lab with a user equipment (UE) simulator. By combining FDD spectrum with TDD spectrum, more users can benefit from carrier aggregation gains.
In total, 400MHz of bandwidth was aggregated with FDD bandwidths ranging 20MHz to 50MHz to achieve the 5.7Gbps throughput.
Sibel Tombaz, Head of Product Line 5G RAN at Ericsson Networks, says: “We are keeping the momentum on carrier aggregation by continuously stretching its potential to boost capacity and speed. Our successful 6CC data call shows how versatile our solution is and that we are poised to work with ecosystem partners to make this new band combination a reality. Our goal, as always, is to help customers meet end users’ growing appetite for high-capacity, ultrahigh-speed 5G.”
