This research aims to design and implement an underwater communication system using radio frequency modules and Arduino. Underwater wireless communication is challenging due to the attenuation of electromagnetic waves in water. However, radio frequency signals in the 433MHz range and the added antenna have shown successful data transfer. For this purpose, measurements are made at different distances, and data is collected in the aquatic environment and free space. A comparative analysis of the values of arrival powers and losses in the studied environment is carried out to verify the efficiency of this study in terms of range, transmission speed, and reliability.

In this paper, a study oriented to Free Space Optics (FSO) is carried out, identifying its main benefits and limitations. A practical case study is also considered in the city of Loja (Ecuador) for designing FSO technology, assessing suitable sites for deployment, climatic conditions and line of sight between the selected nodes, and technical characteristics of the equipment considered. Path loss and channel geometry analyses are also performed, where the results obtained allow understanding under which atmospheric conditions an optimal link is available. The study is validated through the execution of simulations using Optisystem software by considering several study scenarios. One of the actual results identified is the transmission rate supported by FSO technology in different atmospheric conditions, exceeding 3 km, and the high bandwidth offered compared to other technologies, such as RF, that are limited by similar factors.
