The Internet of Things (IoT) has transformed various industries by enabling interconnected devices to collect, share, and analyze data in real-time. A crucial component of this transformation is Long Range (LoRa) technology, designed for low-power, wide-area networks (LPWAN). LoRa enables long-distance communication with minimal energy consumption, making it ideal for IoT applications in sectors like healthcare, agriculture, and smart cities. Specifically, in healthcare, LoRa facilitates remote monitoring through the Internet of Medical Things (IoMT), where patient data, such as vital signs, can be transmitted efficiently over vast distances. This paper discusses the significance of LoRa in medical applications, its advantages, challenges, and solutions, and reviews existing literature on its implementation. Key challenges include low data rates, packet loss, and latency issues, while solutions such as adaptive data rate mechanisms and multi-hop networks offer potential improvements for medical IoT systems. Also based on the given comparison among communication technologies, the consumer can make his decision on chosen the right technology for his application.
