VSAT bandwidth determines the speed and quality of internet onboard a vessel. Higher bandwidth allows seamless streaming, cloud usage, VoIP, and real-time operations. Bandwidth is usually shared among multiple users, and fair usage policies (FUP) may apply. Ku-band and Ka-band offer scalable bandwidths suitable for different marine applications. Bandwidth monitoring tools help in allocating resources efficiently across operations and crew. As vessel digitalization increases, demand for higher VSAT bandwidth is on the rise.
