The IR Light based Communication System aims to develop a secure and efficient means of communication using light signals in environment where radio frequency (RF) transmissions are restricted to undesirable. This system leverages optical communication technologies to ensure robust data transmission while minimizing electromagnetic interference. The challenge is to design and develop IR Light based communication system for marine applications for mobile platform with secure data and voice. These devices are expected to fit on a tripod/ mast using mounting arrangements and remain within the power budgeting of installed equipment. The system should be able to function with full efficiency till at least sea state 4 when deployed on mobile platform. Integration of these devices with existing ship borne systems also is to be undertaken by the system provider. The problem definition statement has deliberately been kept generic and broad based.
