MediaTek M80 5G Baseband

MediaTek officially announced the launch of its new generation 5G baseband chip MediaTek M80, compared to M70 in terms of increased support for millimeter-wave band 5G networks, while also retaining all the advantageous features of M70.

As 5G rollouts accelerate, mmWave is becoming increasingly important, especially in the U.S. MediaTek’s new 5G modem integrates support for both sub-6 GHz and mmWave networks to address this opportunity and give device makers more flexibility. To advance users’ 5G experiences, the new modem supports the latest global cellular standards and specifications and it packs MediaTek’s signature power savings technologies along with ultra-fast speeds.
said JC Hsu, Corporate Vice President and General Manager of MediaTek’s Wireless Communications Business Unit.

Officially, the MediaTek M80 5G baseband has been tested following industry-related standards and is expected to be delivered to customers in 2021 for future use in smartphones, PCs, Mi-Fi, CPE, industrial IoT, and other types of devices.

In terms of specifications, the MediaTek M80 complies with the 3GPP Release 16 standard specification, supports dual connectivity and carrier aggregation in the Sub-6 GHz and millimeter wave bands, supports 5G Sub-6 GHz (FR1) multi-carrier aggregation, 5G millimeter-wave (FR2) up to 8-carrier aggregation, supports carrier aggregation for TDD and FDD, in addition to supporting support for Dynamic Spectrum Sharing (DSS).

With these features, the M80 baseband can achieve a maximum downlink rate of 7.67Gbps and a peak uplink rate of 3.76Gbps, as well as dual SIM dual 5G, dual 5G NSA and SA networks, and dual VoNR. The MediaTek M80 has surpassed the Qualcomm Snapdragon X60 in terms of theoretical speed, with the latter’s uplink and downlink rates being 3Gbps and 7.5Gbps respectively, and is on par with the Exynos 2100‘s 3.67Gbps/7.35Gbps in terms of uplink and beyond in terms of the downlink.

In terms of technical features, the M80 supports MediaTek 5G UltraSave power-saving technology, which can intelligently detect the network environment and identify OTA content, and dynamically adjust the power configuration and operating frequency according to the network environment. It also integrates BWP dynamic bandwidth regulation technology, which automatically adapts to low or high bandwidth to meet different needs of data throughput, optimizing bandwidth usage to the maximum extent.

Besides, M80 also supports C-DRX energy-saving management technology, which can automatically switch between active and dormant states to maintain connectivity while reducing communication power consumption.
