5G will become the basis for a fully mobile and networked society. Covestro is developing innovative and sustainable material solutions and contributing to a smart infrastructure, including sensor technologies and a digital communication environment.

They include, for example, low temperature impact modified solutions, AAU weight reduction solutions, radio frequency data transmittance studies, thermal management solutions, electronic integration solutions and recycled materials based on the polycarbonate materials family of Makrolon , Bayblend, Makroblend and Apec from Covestro.

At K 2019, Covestro will present some prototypes. The project is part of the company´s comprehensive digitalization strategy.

New telecommunications infrastructure

To increase public acceptance of an expanded network of antennas and base stations, Covestro is working with students from the renowned Umeå Institute of Design and Deutsche Telekom to seamlessly integrate these technical facilities into the cities of the future.

The project includes the development of attractive base stations, their color matching and surface structuring. Düsseldorf served as a reference city for the project.

Flexibility in antenna design

Covestro will enter this market in a hypothetical scenario with its own product range. The actual product is the outer sheath of a third-party antenna, which is designed to adapt to specific environments by either fitting in or protruding from it, depending on the environment and population density.

At K 2019, the company will be showing a series of technical and design prototypes for small cells in the frequency range of 3.5 GHz and 28 GHz.

In Asia Pacific, which leads in 5G network deployment, Covestro is working with Southeast University of China on the optimization of radio frequency data transmittance.

“We can help our customers to enjoy more design freedom while ensuring the 5G data transmittance performance with state-of-art testing capabilities in a broad frequency range of up to 110 GHz under a variety of environmental conditions, all in our Asia Pacific Innovation Center in Shanghai,” said Nan Hu, Global Marketing Leader of Electronics at the Polycarbonates Segment of Covestro.

New film solution for 5G smartphones

5G technology, with its high transfer rates, will also have a significant impact on smartphone design. The antennas for 5G technology require more space. That is just one reason why metal solutions used to date for the back of devices will in future be replaced by ceramics, glass or plastics.

A Makrofol SR multilayer film solution with acrylic top layer combined with a new manufacturing process results in mobile phone back covers that look like glass but are not fragile.

This crystal clear, 3D formable and 5G compatible film material is specifically engineered for optimal design freedom for mobile phone brands to create fashionable mobile phones using decoration technologies such as UV patterning and non-conductive vacuum metallization (NCVM).

More than 50% of the mobile phone market in China is currently switching to such multi-layer PC/PMMA film solutions – a sign of a promising future for the coming 5G era.
