Huawei launches most powerful 5G antennas

At Mobile World Congress MWC 2019, Huawei unveiled its most powerful “1+1” antennas. Including the industry’s first 30-port antenna, the industry’s smallest convergent antenna FDD 4T4R+TDD 8T8R and the industry’s first fully integrated ultra-wideband multi-sector antenna. These products meet the maximum requirements for a single passive antenna to support all frequency bands in a variety of use cases, as well as for redundant space for 5G Massive MIMO module deployment and immediate 5G activation.

Based on three 5G antenna platforms – Munich, London and Bangkok – Huawei presented the following three high-profile products at the congress.

Munich platform: The smallest antenna with 30 ports supports broadband deployment of 4T4R in bands below 3 GHz and independent tuning of each band coverage. It is suitable for operators who have a wide range of frequencies at their disposal as well as for those who share antennas.

London Platform: At only 1.5 meters in length, one antenna supports FDD 4T4R and TDD 8T8R deployments, provides ultra-efficient deployment of 5G nodes, facilitates migration to 5G technologies without requiring more space for antennas, and enables fast activation of 5G networks.

The Bangkok Platform

The product is designed for next-generation FDD bandwidth expansion solutions and increases throughput by more than 2.5 times. A single antenna supports a flexible 4T4R hybrid configuration with 6 sectors and 4T4R with 3 sectors, optimizing spectrum efficiency as well as site resources.

In early 2018, Huawei pioneered the “1+1” antenna concept for 5G networks and launched the “1+1” series of universal antenna systems designed specifically for 5G. These solutions aim to overcome the problems associated with upgrading sites to support 5G networks, such as lack of space, high total cost of ownership and difficulty of acquisition. They provide ultra-efficient 5G site deployments. To meet growing requirements, Huawei has continued to invest in research and development, created many advanced technologies, and applied them to new products.

Innovative architecture reduces antenna size. The multilayer interleaved design reduces the size of a converged FDD/TDD antenna by about 50% compared to a traditional architecture. The width of devices using parallel array architecture is more than 10% smaller than their counterparts, yet they provide 2 dB higher gain.

Advanced technology increases efficiency and reliability. AirMAX technology increases radiation efficiency by 18% and significantly improves antenna reliability and performance.

Fundamental research

Fundamental research is enabling the continuous development of antennas. The MQ4/MQ5 cluster connector, which NGMN chose as a solution for early 5G network deployments, enables the development of 5G antennas that support more than 10 bands, and greatly simplifies antenna installation and maintenance. The new GFRPP antenna fairing material, which is 40 percent lighter than traditional fiberglass, can support the weight of a multiband antenna up to 50 kg, avoiding the need to lift it, and saving installation time and cost.

Mr. Zhang Jiayi, president of the antenna development division at Huawei, commented:

“We are well aware that one of the most difficult challenges in deploying 5G sites is the lack of space for antennas. Therefore, Huawei has worked hard in research and development to offer advanced, innovative ‘1+1’ antenna solutions to telecom operators to enable ultra-efficient deployment of 5G sites and help them achieve business success in the era of 5G technology.”
