Data Transmission Distance Actual Measurement According to Receiver Height for LPWA-based IoT Application
Kyoung-Woo Cho, Chang-Heon Oh · International Journal of Control and Automation · 2018
The low-power wide area (LPWA) standard is attracting attention as a communication technology suitable for sensor-based IoT applications owing to its low power consumption and wide coverage.However, one disadvantage is that the communication distance differs depending on the application environment or gateway arrangement.In this paper, the data transmission distance is measured according to receiver height to check the influence of communication distance when the LPWA-based IoT application is deployed in different environments; the LoRaWAN of the LPWA standard technology is used to check the communication distance when the receiver height is different in an NLoS environment.Our experimental results demonstrate that smooth communication is impossible based on the receiver height, even at a position less than half of the maximum transmission distance.
