To obtain the envisioned 1000-fold capacity increase of next-generation wireless networks, 5G needs many new frequency bands, smaller cells as well as denser frequency reuse. These requirements put totally new demands on the materials used in the base stations and mobile devices.
Since the material losses increase with increasing frequency, it is not crucial to consider the dielectric losses on Sub-6 GHz frequency bands, but this is not true at mmWaves. A high- and low-loss material, which at 2.4 GHz might give almost the same performance, will be very different at 70 GHz in favor of the low-loss material.
The frequency reuse necessitates improved MIMO antenna systems, which in turn needs materials with stable and tightly controlled dielectric properties as well as consistent performance in all use conditions and good moldability. To achieve this, accurate processes are required in quality control and in characterization of the dielectric properties. Also, material properties at mmWaves is mandatory when designing RF components at these frequencies.
In this presentation, effects of material losses are shown in very concrete ways via industrial examples.

With 5G right behind the corner, it is no surprise that it will not come for free. Upgrading the network infrastructure to be 5G compatible will require annual investments of several hundreds of billions of euros for Europe alone. This requires a solid business case and services for which 5G users are prepared to pay.
When evaluating the investments for the entire network, we should never focus on the cost of a single base station. Although a cheaper material will save you a few bucks in one antenna, the decreased RF performance will cost you much more as there might be a need for a larger amount of base stations, or larger energy consumption. Material choices will also affect the manufacturing costs, as well as the infrastructure lifetime costs.
In this presentation, the benefits of optimal material choices are made concrete through industrial examples.
