Ericsson has achieved a record 5.7 Gbps downlink speeds on 5G Carrier Aggregation by combining six component carriers in the world's first 6CC (component carrier) data call. Ericsson stated that the achievement marks a significant leap forward in Carrier Aggregation (CA), promising to reshape the landscape of data speeds and connectivity.

6CC Carrier Aggregation
According to the statement, the data call was achieved using three Frequency Division Duplex (FDD) bands and three Time Division Duplex (TDD) bands within the sub-6GHz frequency range. This combination was made possible through Ericsson's RAN Compute hardware, carrier aggregation software, and Advanced RAN Coordination functionality.
Carrier Aggregation
Carrier aggregation is a technique in wireless communication where multiple frequency bands are combined to increase data throughput and capacity. In this case, three FDD bands and three TDD bands were aggregated to achieve higher data speeds.
Benefits of Spectrum Combination
This achievement was validated within an Ericsson laboratory, utilizing a user equipment (UE) simulator to carry out the 3FDD + 3TDD carrier aggregation testing. By combining FDD and TDD spectrum, more users can benefit from the improved data speeds and capacity achieved through carrier aggregation. This allows for better user experiences in terms of audio and video streaming, faster file downloads, and smoother performance for data-intensive applications.

Throughput Achievement
The test resulted in a throughput of 5.7 Gbps (gigabits per second) using a total aggregated bandwidth of 400 MHz. Ericsson said this throughput was achieved by aggregating FDD bandwidths ranging from 20 MHz to 50 MHz.
Six-Component Carrier Capability
The technology used in this achievement enables carriers (communication service providers) to optimize their network resources by utilizing six-component carriers. This optimization enhances network efficiency and delivers high data speeds, particularly for downlink-heavy applications.

Ericsson Networks stated: "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."
Ericsson further added Carrier Aggregation is crucial to getting the best possible 5G performance out of scattered spectrum assets. And with 6CC, service providers will be able to maximize the use of allocated spectrum and optimize the combined bandwidth for superior mobile experience."
