Abstract	Long Range (LoRa) is a new low power low-cost wireless Internet of Things (IoT) technology to form low power wide area network (LPWAN) which has been gaining importance in recent time for various applications like health care, agriculture, industrial IoT, smart cities, smart parking, and many more. LoRa is based on Chirp Spread Spectrum (CSS) technology and uses the entire bandwidth to broadcast signal, providing resilience against channel noise, doppler effect and fading. The performance of LoRa depends on the pathloss factor, bandwidth and spreading factor. In this paper, we first conduct an extensive review and analysis of current wireless technologies, comparing them with LoRa to understand the rationale behind LoRa communication. Then several pathloss measurements in different environmental channel conditions related to spreading factors have been shown and characterize prior to use the LoRa Tx-Rx module in single hop communication link for health data transmission that provides the maximum coverage for reliable data reception using LoRa point-to-point link. Earlier version of LoRa v2 is now replaced by LoRa v3 for which limited research articles are available. For wide scale applications using LoRa v3 modules, this experimental research will help researchers to adopt the best parameters for LoRa based IoT system. © 2024 IEEE.
