This four-component carrier (4CC) aggregation combination will increase the 5G deployment options for communications service providers by blending different frequency bands.
In an interoperability development test (IoDT), the two companies completed the 5G data call using one low-band and three mid-band channels in the sub-7GHz frequency range (FR1) bands, where typically most of the 5G data traffic is carried.
The higher throughput that this 4CC combination enables will enhance user experience with faster downloads and seamless video streaming for smartphone users and fixed wireless access subscribers. For service providers,
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

Carrier Aggregation is key to deploying high-performing 5G networks. It provides the unique capability to combine many frequency bands, enabling higher speeds and increased cell coverage that improve capacity and user experience. The speed boost can mean better audio and video quality for streaming users, faster file downloads, and a better working environment for digital nomads. By combining FDD spectrum with TDD spectrum, more users can benefit from carrier aggregation gains.
The downlink peak rate of nearly 4.4 Gbps was reached by combining 20MHz of AWS (Advanced Wireless Service) band, 80MHz of CBRS (Citizens Broadband Radio Service) band and 200MHz of C-band spectrum. The test was carried out using MediaTek M80 5G modem,
