INMARSAT FB (FleetBroadband) network configuration

The INMARSAT BGAN/FB services use a dedicated access point established in Tokyo.

Access for BGAN/FB up to now Access for BGAN/FB through KDDI access point (Shinjuku)
A global IP address is assigned to the terminal each time you access the service As well as a global/private address being assigned, a fixed private address is also assigned to the terminal each time you access the service
Data connection available only through the Internet Data connection through a secure access line
Streaming possible only in the satellite sector Bandwidth guaranteed, end-to-end transmissions now possible
Nothing added by KDDI Now providing customer services and network monitoring

An INMARSAT BGAN/FB access point (AP) was established in Tokyo in September 2008.
This access point in Tokyo has made the following modes of use possible.

No applications are necessary to use KDDI's access points. And, they are free to use!

All you have to do is change your current access point (bgan.inmarsat.com) to the new one (kddi.bgan.inmarsat.com). For details, please contact us.

To have a static IP address (private) assigned costs 2,000 yen (one-time payment) per IP address.

INMARSAT FB (FleetBroadband) coverage

<Current coverage>

Figure: Current coverage

  • The satellite coverage area changed following the creation of new INMARSAT satellite regions on March 25, 2015. For use in Brazil (where EMEA satellite coverage overlaps with America satellite coverage), change the configuration of your terminal to access the America satellite.
    For use in India, Sri Lanka, and Nepal (where EMEA satellite coverage overlaps with Asia-Pacific satellite coverage), change the configuration of your terminal to access the Asia-Pacific satellite.

Emergency distress communication communications can also be made from INMARSAT FB (Fleet Broadband).

You can make free emergency distress communications by dialing "505". (Note that 505 emergency distress communications differ from GMDSS [2].)

Applicable terminals INMARSAT FB (FleetBroadband) 500, 250, and 150
How to use Dial 505. You will be directly connected to a rescue station in one of three possible locations. You can dial 505 even while using IP data transfer, but not while using ISDN. When using ISDN, disconnect the ISDN connection first and then dial.

KDDI is planning to phase GMDSS [1] communication into INMARSAT FB services.

  • [2]
    GMDSS is short for "Global Maritime Distress and Safety System," a global system for maritime distress calls and safety.
    Maritime communication made a complete switch from the Morse code transmission system to GMDSS in 1999. Cargo ships 300 tons and over engaging in international maritime transport and all passenger ships are required by law to be equipped with GMDSS equipment.
