In an interoperability development test (IoDT), Ericsson and MediaTek have completed a successful 5G Data call using low-band and three mid-band channels in the Sub-7 GHz frequency range (FR1) bands. These bands carry most of the telco 5G traffic.
Ericsson and MediaTek have successfully performed Carrier Aggregation (CA) by merging four channels to deliver a downlink speed of 4.36 Gbps.

Ericsson and MediaTek have performed four component carrier (4CC) aggregation combination – one FDD (frequency division duplex) and three TDD (time division duplex) to deliver the highest known download speed of 4.36 Gbps on this band combination which will increase the 5G deployment options for Communication Service Providers (CSPs) by enabling different frequency band combinations.
This 4CC combination allows for increased throughput, which will improve user experience by enabling faster downloads and seamless video streaming for both smartphone users and fixed wireless access (FWA) subscribers. In addition, Ericsson’s flexible Carrier Aggregation solution will enable service providers to make the most out of their available spectrum assets and provide high-quality 5G connectivity.

Spectrum:
According to the statement, the downlink peak rate of nearly 4.4 Gbps was reached by combining 20 MHz of the AWS (Advanced Wireless Service) band, 80MHz of the CBRS (Citizens Broadband Radio Service) band and 200MHz of the C-band spectrum.
Radio Equipment & Modem:
The test was carried out using MediaTek M80 5G modem, Ericsson’s Baseband 6648, TDD Massive MIMO radios AIR 3268, AIR 3239, and TDD Radio 4426.
