Quantitative indoor monitoring, in a low-invasive and accurate way, is still an unmet need in clinical practice. Indoor environments are more challenging than outdoor environments, and are where patients experience difficulty in performing activities of daily living (ADLs). In line with the recent trends of telemedicine, there is an ongoing positive impulse in moving medical assistance and management from hospitals to home settings. Different technologies have been proposed for indoor monitoring over the past decades, with different degrees of invasiveness, complexity, and capabilities in full-body monitoring. The major classes of devices proposed are inertial-based sensors (IMU), vision-based devices, and geomagnetic and radiofrequency (RF) based sensors. In recent years, among all available technologies, there has been an increasing interest in using RF-based technology because it can provide a more accurate and reliable method of tracking patients' movements compared to other methods, such as camera-based systems or wearable sensors. Indeed, RF technology compared to the other two techniques has higher compliance, low energy consumption, does not need to be worn, is less susceptible to noise, is not affected by lighting or other physical obstacles, has a high temporal resolution without a limited angle of view, and fewer privacy issues. The aim of the present narrative review was to describe the potential applications of RF-based indoor monitoring techniques and highlight their differences compared to other monitoring technologies.
定量的室内监测，以一种低侵入性和准确的方式，在临床实践中仍然是一个未满足的需求。室内环境比室外环境更具挑战性，是患者在日常生活活动（ADL）中感到困难的地方。随着远程医疗的最新趋势，将医疗援助和管理从医院转移到家庭环境的积极趋势正在持续。在过去几十年中，已经提出了不同的技术用于室内监测，这些技术在全身监测方面具有不同程度的侵入性、复杂性和能力。提出的主要设备类别是基于惯性的传感器（IMU）、基于视觉的设备以及地磁和射频（RF）传感器。近年来，在所有可用技术中，人们对使用基于 RF 的技术越来越感兴趣，因为与其他方法（如基于摄像头的系统或可穿戴传感器）相比，它可以提供更准确和可靠的跟踪患者运动的方法。实际上，与其他两种技术相比，RF 技术具有更高的顺应性、低能耗、无需佩戴、不易受到噪声干扰、不受照明或其他物理障碍的影响、具有高时间分辨率且视角不受限制、以及隐私问题较少。本叙述性综述的目的是描述基于 RF 的室内监测技术的潜在应用，并突出它们与其他监测技术的差异。
