Ericsson, MediaTek Expand 5G Deployment Options

Four channels, one FDD (frequency division duplex) and three TDD (time division duplex), were successfully combined by Ericsson and MediaTek to achieve a downlink speed of 4.36 Gbps, the highest known speed based on this band combination.

Leveraging 5G Services

By combining various frequency bands, this four-component carrier (4CC) aggregation combination will give communications service providers more 5G deployment alternatives.

The two businesses successfully completed a 5G data connection in an interoperability development test (IoDT) using one low-band and three mid-band channels in the sub-7GHz frequency range (FR1) bands, which is normally where most 5G data traffic is transmitted.

For customers to fixed wireless access as well as users of smartphones, the enhanced throughput that this 4CC combination provides will improve user experience with quicker downloads and flawless video streaming. Service providers will be able to deliver high-quality 5G connectivity by making the most of the available spectrum assets thanks to Ericsson’s adaptable carrier aggregation technology.

The highest possible 5G performance from scattered spectrum assets requires carrier aggregation, according to Sibel Tombaz, Head of Product Line 5G RAN at Ericsson Networks. In order to increase capacity and coverage, Ericsson is constantly investigating all potential frequency band combinations. We have also demonstrated that carrier aggregation is a game-changer for maximizing the combined capacity of licensed spectrum assets to deliver faster data speeds to a larger user base.

According to HC Hwang, general manager of MediaTek’s Wireless Communication System and Partnership:

 The technological achievement demonstrates MediaTek’s continued leadership in NR CA innovation. MediaTek is developing and testing the upcoming 5G SA technologies in close cooperation with business partners like Ericsson, ready for integration into our top-tier 5G modems.

High-performance 5G network deployment depends on carrier aggregation. By combining multiple frequency bands, it offers the special potential to increase speed and cell coverage, enhancing capacity and user experience.

The increase in speed may result in faster file downloads, better audio and video quality for streaming users, and a better working environment for digital nomads. More users can gain from carrier aggregation gains by combining FDD and TDD spectrum.

By combining 20MHz of the AWS (Advanced Wireless Service) band, 80MHz of the CBRS (Citizens Broadband Radio Service) band, and 200MHz of C-band spectrum, a downlink peak rate of about 4.4 Gbps was achieved.

The MediaTek M80 5G modem, Ericsson’s Baseband 6648, TDD Massive MIMO radios AIR3268, AIR3239, and TDD Radio 4426 were used to conduct the test.
