Ericsson and MediaTek have successfully merged four channels – one FDD (frequency division duplex) and three TDD (time division duplex)– to deliver a downlink speed of 4.36 Gbps, the highest known speed based on this band combination. This four-component carrier (4CC) aggregation combination will increase the 5G deployment options for communications service providers by blending different frequency bands.
Sibel Tombaz, Head of Product Line 5G RAN at Ericsson Networks, says: “Carrier Aggregation is crucial to getting the best possible 5G performance out of scattered spectrum assets. At Ericsson, we are persistently exploring all possible frequency band combinations to boost capacity and coverage. We have also shown that Carrier Aggregation is a game changer when it comes to optimizing the combined bandwidth of allocated spectrum assets to deliver higher date rates for a greater number of users.”
