ZTE, MediaTek complete industry’s first 5G carrier aggregation for end-to-end commercial systems


ZTE Corporation, a major international provider of telecommunications, enterprise and consumer technology solutions for mobile internet, in collaboration with MediaTek, have taken the lead to complete the industry’s first 5G carrier aggregation verification of 700MHz and 2.6GHz spectrum based on commercial terminal chips, in Xi’an, China.

Based on ZTE’s commercial 5G wireless base stations and its latest 5G core network equipment, along with the 5G test terminal featuring MediaTek Dimensity 800U 5G-integrated SoC, ZTE and MediaTek have verified dual-carrier aggregation of 30MHz over 700MHz and 100MHz over 2.6 GHz, achieving an effective downlink data throughput of 1.849 Gbps.

Committed to the development of 5G industry, ZTE has invested heavily in the development of 700 MHz products, and has actively cooperated with industry partners to accelerate the commercialization of the 700 MHz frequency band.

This comes at a time when ZTE and their Chinese competitor, Huawei are being kicked completely out India and out of the 5G network development in other countries across the world.

In addition to releasing a series of 700 MHz commercial products, ZTE has also completed 700MHz SA networks, 700MHz VoNR (Voice over New Radio), and the  end-to-end interconnection tests on 30MHz, so as to strengthen the integration of Sub 1GHz & Sub 6GHz as well as the application research on 700MHz.

The verification of 700MHz and 2.6GHz carrier aggregation will further enrich the 700MHz network solution, thereby facilitating the 5G commercial construction in the 700MHz frequency band and providing a good reference for the global Sub 1GHz & Sub 6GHz development.

This verification is another major breakthrough in 700MHz for ZTE and MediaTek, following the two parties’ joint completion of a 700MHz VoNR call in May 2020, and data interconnection of 30MHz bandwidth over 700MHz in July 2020.

ZTE is a provider of advanced telecommunications systems, mobile devices and enterprise technology solutions to consumers, operators, companies and public sector customers. The company has been committed to providing customers with integrated end-to-end innovations to deliver excellence and value as the telecommunications and information technology sectors converge.

Listed in the stock exchanges of Hong Kong and Shenzhen, ZTE sells its products and services in more than 160 countries.
