Abstract
This paper reviews the fundamentals and applications of RF-based localisation techniques, focusing on phase-based methods. RF-based localisation uses radio frequency signals to determine the position and orientation of a target, such as a patient, device, or object, in indoor environments. Phase-based methods exploit the phase difference between the transmitted and received signals to estimate the distance and direction of the target. These methods have advantages such as high accuracy, low cost, and real-time performance but also face challenges such as interference, noise, and phase ambiguity. The paper discusses the physics and properties of RF waves, RF-based localisation systems' main components and algorithms, and the current uses and challenges of RF-based localisation in healthcare settings. The paper also provides a comparative analysis of different RF-based localisation techniques and technologies, such as RFID, Wi-Fi, Bluetooth, and UWB. The paper concludes with future directions and open issues for research and development in this field.
