Abstract : OceanNet project uses a hierarchical point-to-multi-point backhaul network using long range Wi-Fi technology to provide extended offshore connectivity for fishing vessels. This work is aimed to understand the interrelationship between the design parameters and the reason for considering specific parameter values for the OceanNet solution. The research work explores the communication systems theoretical limits on received power with respect to the variation due to transmitted power, distance, antenna type, frequency, and modulation schemes. These different models that explain the interrelationship are simulated to gain deeper understanding to the design of communication systems. This paper discusses the variation in received power and transmitted power with respect to change in distance for a given frequency, comparison of channel bandwidth with channel capacity, analysis of signal to noise ratio and its impact on different modulation schemes. We also analyse different antenna types used for the deployment and how the performance is affected due to congestion in the nodes. This paper also details the results and analysis of the simulation performed based on fishing vessel scenario
