RF Digital Twin for Wireless Maritime Communication Channel and Pathloss Modeling for fishing vessel LR WiFi networks

In recent years, Non-Terrestrial Networks (NTN) solutions have gained attention for maritime activities on vessels, particularly deep-sea fishing vessels in coastal parts of India. Traditional marine VHF systems are used for regular and emergency communication, but have a limited range, and adverse weather conditions can cause attenuation, distortion, and interference. Line-of-sight (LoS) propagation also limits VHF radio coverage, making them susceptible to shadow zones and dead spots. Low Earth Orbit (LEO) satellites like Starlink and OneWeb, and Medium Earth Orbit (MEO) satellites like SES demonstrated high throughput and low latency. However, many countries still need to address spectrum regulations and expensive costs, particularly for fishing vessels. Other maritime communication alternatives are Unmanned Aerial Vehicles (UAVs), Low Altitude Platforms (LAPs), and High Altitude Platforms (HAPs).  This project aims to build an end to end RF digital twin for Long range WiFi communication network via integrated sensing and communication(ISAC) to predict the channel performance and thereby deliver proper QoS based services to the end user based on channel conditions.
