Utilizing satellite communication systems has been crucial in this regard as they offer the bandwidth and dependability for enabling instant communication, in maritime settings. Impact of Communication Bottlenecks on Autonomous Operations Communication obstacles pose a hurdle, in ensuring the functioning of self sailing maritime systems.. Unstable or inconsistent communication channels can hamper the efficiency of systems by causing delays and lowering their decision making abilities..

In order to address these obstacles effectively and improve communication speed, between ships and control centers on land in real time scenarios is by introducing generation (5g) networks as a potential solution proposed by Ait Allal et al., (2020) and Idoko et al., 2024.. The utilization of 5g technology is said to decrease latency to, under one millisecond and enhance data transfer speeds up to a hundredfold compared to existing communication systems. This measure would guarantee an trustworthy transfer of information, for upholding the safety and performance effectiveness of self-operating systems.. In Table 2 summarizing the obstacles, in communication for maritime operations reveals five significant hurdles encountered - from lost communications with autonomous systems to underwater bandwidth and latency problems to diminished decision making abilities and coordination issues for marine robots – along with the proposed remedy of utilizing 5G networks as a solution option for these challenges that impact system performance negatively leading to delays in operations and heightened risks of accidents along, with decreased overall system efficiency. To tackle these challenges effectively suggested solutions involve enhancing tools; creating underwater communication technologies, with greater bandwidth; refining coordination algorithms; and integrating 5th generation networks that facilitate instant data sharing, with minimal delays to boost safety and productivity at the same time.
