Ericsson has extended the limits of 5G Carrier Aggregation by combining six component carriers (6CC) to reach a record download speed of 5.7 Gbps.
The milestone was achieved by merging three Frequency Division Duplex (FDD) bands with three Time Division Duplex (TDD) bands within the sub-6 GHz spectrum.
Sibel Tombaz, Head of Product Line 5G RAN at Ericsson Networks, commented:
“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, ultra high-speed 5G.”
Ericsson used its RAN Compute hardware, advanced carrier aggregation software, and new Advanced RAN Coordination features to enable this result.
The test aggregated 400 MHz of bandwidth inside an Ericsson laboratory using a dedicated user equipment (UE) simulator to validate performance under controlled conditions.
By combining FDD and TDD spectrums, Ericsson not only recorded a peak throughput of 5.7 Gbps but also demonstrated a method for distributing carrier aggregation advantages more efficiently across many users.
This approach is especially relevant as demand for data-heavy applications continues to grow.
Aggregating FDD bandwidths from 20 MHz to 50 MHz across six component carriers enables service providers to make better use of existing network and spectrum assets. The result is higher data speeds and greater capacity, improving experiences for streaming high-quality audio and video, fast file downloads, and reliable remote work for mobile professionals.
“Carrier Aggregation is crucial to getting the best possible 5G performance out of scattered spectrum assets,” Tombaz added. “With 6CC, service providers can maximise allocated spectrum and optimise combined bandwidth for a superior mobile experience.”
As connectivity needs evolve, Ericsson’s achievement represents a significant advancement toward higher throughput and a smoother digital experience for users worldwide.
