Carrier Phase Stability Measurement

As we approach higher and higher localization and sensing accuracies with 6G technologies, the radiocapabilities and signal processing will cease to be the main accuracy limitations, and other physicalphenomena start to play an increasingly critical role. In this paper, we investigate how radio-based physicalmeasurements, including radar, wireless localization and Integrated Sensing and Communication (ISAC),can be affected by environmental conditions, and at what level of accuracy and dimensional and temporalscales these effects become significant. Specifically, we produce and publish a dataset where the long- termstability of radio-based range measurements is empirically assessed, showing peak-to-peak variations of 0.3mm over a 1 m range (which scales linearly, e.g. 3 mm over 10 m or 3 cm over 100 m) over 6 months.
