Respiratory illness diagnosis and continuous monitoring are becoming popular as sensitive markers of chronic diseases. This interest has motivated the increased development of respiratory illness diagnosis by exploiting wireless communication as a sensing system. Several methods for diagnosing a respiratory illness are based on multiple sensors and techniques. Depending on whether the device embeds the sensor in contact with the body or not, these techniques are commonly categorized as contact based or contactless. Contactless methods have gained increasing popularity due to their ubiquitous nature, non-intrusiveness, and low cost. However, contactless methods are difficult to implement, with several challenges such as dynamic wireless communication environments. This article comprehensively reviews all contactless respiratory illnesses using wireless communication sensing methods, their associated challenges, and issues. In addition, applications of respiratory illness diagnosis methods using wireless communication are provided to investigate each method's potential development and applicability. Continuous and accurate diagnosis of respiratory illness using wireless communication sensing systems can assist caregivers in enhancing the care quality and bestowing patients with more freedom for both inpatients and outpatients. Furthermore, wireless communication monitoring systems could lead to treatment plans remotely more effectively, decrease the duration of patient stays in medical facilities, and reduce overall treatment costs.

呼吸系统疾病诊断和持续监测作为慢性病的敏感标志物正变得越来越流行。这种兴趣推动了利用无线通信作为传感系统来诊断呼吸系统疾病的发展。诊断呼吸系统疾病的几种方法基于多种传感器和技术。根据设备是否嵌入与身体接触的传感器，这些技术通常分为接触式或非接触式。非接触式方法由于其普遍性、非侵入性和低成本而越来越受欢迎。然而，非接触式方法很难实施，面临动态无线通信环境等挑战。本文全面回顾了使用无线通信传感方法的所有非接触式呼吸系统疾病及其相关挑战和问题。此外，还提供了使用无线通信的呼吸系统疾病诊断方法的应用，以研究每种方法的潜在发展和适用性。使用无线通信传感系统对呼吸系统疾病进行连续、准确的诊断可以帮助护理人员提高护理质量，并为住院患者和门诊患者提供更多的自由。此外，无线通信监控系统可以更有效地远程制定治疗计划，减少患者在医疗机构的停留时间，并降低总体治疗成本。
