Description
Next to frequency range 1 (FR1), which convers all frequency bands situated between 410 MHz and 7125 MHz, the fifth generation telecommunication (5G) also introduced the usage of frequency range 2 (FR2). FR2 stretches from 24.25 GHz to 71.0 GHz which is quiet a jump in frequencies compared to the frequencies used for previously deployed technologies (2G, 3G, and 4G). The introduction of this frequency range requires the need for new measurement protocols and equipment to measure radio frequency electromagnetic field (RF-EMFs) exposure induced by 5G communication at these mmWave frequencies. For FR1, several low-cost and compact RF-EMF exposure sensors already exist and are deployed in large scale RF-EMF monitoring networks. But, the concept of the FR1 RF-EMF sensor cannot be replicated to achieve similar performances i.e. similar dynamic range, to monitor FR2 without “breaking the bank” – they are expensive. To realise an FR2 RF-EMF exposure sensor, a novel approach based on a mixer is proposed. Initial testing of the mixer was performed. The next steps of the prototype are also discussed.
