In this paper, the authors review proposed realization concepts and achievements of wireless sensor nodes and focuses on new developments in the 24GHz frequency range. The relatively high frequency offers the advantage of ultra-miniaturization and therefore opens new application fields. On the other hand power consumption of the RF-front-end becomes still more challenging than at lower frequencies. It is shown that by applying very simple CMOS transceiver architectures and modulation schemes combined with innovative efficient wake-up concepts, very low energy consumption can be achieved.
