System Configuration


With its simultaneous voice and data capability, FELCOM251 and FELCOM501 can support an extensive range of user applications. All tasks can be conducted all at the same time through a single terminal. N.B., Certain network devices must be arranged locally, in order for you to make use of some of the applications.

Social communication and increased welfare for crewmembers.

Crewmembers are now able to make private phone calls or send SMS using their SIM card to their friends and families back home. They can also browse the web to read news from home, or any other activity connecting them to the land.

Educational opportunities for crewmembers using distance learning.

Using their off-duty time in a more productive manner has become very popular amongst navigators. VSAT allows crewmembers to attend off-campus distance learning courses through IP applications such as.

Troubleshooting in case of equipment failure.

In case of failure of engine or other onboard equipment, chief engineers onboard can set up live, on-the-spot remote condition-review and troubleshooting sessions with service engineers from various manufacturers onshore. A reliable high bandwidth connection is essential for enabling these functions, and FleetBroadband provides a perfect solution.
