Introduction to FleetBroadband Services

Features of Inmarsat FleetBroadband service applications

Selectable data rates for data communications according to needs:

Standard IP:

  • Service providing best effort delivery of 432 kbps (FELCOM500, 284 kbps for FELCOM250)
    (connected through a shared connection pipe: less traffic—higher throughput, and more traffic—lower throughput)
  • Data service charged for data sent and received
  • Suitable for typical office applications such as e-mail, web browsing, etc.

Streaming IP:

  • Guaranteed streaming data rates on demand, rates selectable from 8, 16, 32, 64, 128 or 256 kbps
    (no contention amongst those who are connected in the same network—guaranteed throughput at all times)
  • Suitable for bandwidth-hungry large data transfer, i.e., real-time video streaming and audio, Voice over IP, etc.
  • Service charged for the duration of the connection to the network
  • These dedicated streaming channels can run independently while the standard IP service is running in the background, meaning that a host of applications can be running simultaneously

Crystal clear voice telephony

  • 4 kbps cost-effective, landline quality speech available
  • Supports one circuit switched service at any one time
  • Simultaneous use together with data communications

High stability in communication links achieves constant network availability even under harsh environmental conditions

Supports additional core voice and ISDN data capabilities for integration with legacy applications

  • ISDN compatibility available on FELCOM500

SMS (up to 160 characters)

System Overview of FleetBroadband

What is a shared service (Standard IP)?

A FleetBroadband Standard IP connection provides a shared channel to the network. Shared service means that multiple vessels (customers) are connected to the network through a shared connection pipe. If more vessels try to utilize the network (higher throughput) at the same time, there will be more communication traffic within the connection pipe (lower throughput).

What is a dedicated service (Streaming IP)?

A FleetBroadband Streaming IP connection delivers dedicated bandwidth to a vessel (the customer). Since customers are allocated with a guaranteed bandwidth, there will be no contention amongst multiple vessels that are connected in the network, meaning that the customer is able to enjoy guaranteed bandwidth at all times.
