2.4 GHz remote controls (PoD)

In the first years of the new millennium, a revolution took place in remote control technology with 2.4 GHz. After frequencies in the two-digit MHz range had been the state of the art for many years, remote controls have conquered the band between 2.4 and 2.48 GHz. In addition to the basics and characteristics of 2.4 GHz radio waves, our author, Prof. Dr Roland Büchi, also teaches the practical aspects: such as the optimal alignment of antennas in model building, the correct arrangement of components in the model, the programming and configuration of remote controls as well as the avoidance and elimination of interference.
