The Radio Waves Display: An intuitive way to show green techniques for 5G to the general public

In this paper, we present a new and intuitive way to show important green techniques for the future fifth generation of mobile networks such as adaptive beamforming to the general public. We use a new device called the Radio Waves Display, which is a one meter square panel composed of twenty by twenty radio frequency sensors spaced by five cm. The Electromagnetic Field strength measured by each sensor is converted into visible light. This new device enables a direct visualization of the waves that pass through it, in real time. It enables us to show to the general public, which is naturally more concerned about the energy consumption of devices, that the network energy efficiency as well can be improved. Most of the presented demonstrations have been effectively shown to a general public at the Mobile World Congress 2016 and other events.
