Underwater to above water LoRa transmission: technical issues and preliminary tests

• Abstract:

  The aim of this paper is to discuss the usability of Long Range (LoRa) communication technology for the transmission of data collected under fresh water to a Gateway positioned outside water. The technical feasibility of the LoRa transmission channel is discussed from a theoretical point of view, focusing on the definition of the link budget for the proposed scenario. The operation of a prototypal LoRa sensor node is then tested in a real scenario, analyzing the performances according to the different Spreading Factors (SF). Actual data transmission is achieved at a depth of 30 cm, thus suggesting the usage of such a technology for real time monitoring applications in environments, like swimming pools, rivers or fish farms.
