INMARSAT LAUNCHES FLEETBROADBAND MULTI-VOICE

17th May 2012 - Inmarsat (LSE:ISAT.L), the leading provider of global mobile satellite communications services, today announced the launch of FleetBroadband Multi-voice, a new capability that will allow up to 9 simultaneous telephone calls to be made through a single FleetBroadband terminal.

The enhancement to FleetBroadband (FB) will enable vessel owners and managers to separate crew communications from operational use. It will also provide crew with more privacy, making it easier to make personal low-cost calls away from the bridge. The new capability is targeted at any vessel with the need to manage separate voice calls - particularly the merchant maritime market, but also other vessels that have similar crew or passenger communications requirements, such as superyachts or deep-sea fishing vessels.

Uniquely, FleetBroadband Multi-voice is integrated into Inmarsat's core network and terminated into public telephone networks, ensuring a high-quality voice service. There are two levels of FleetBroadband Multi-voice available:

·; Standard, which supports up to four simultaneous calls from a FleetBroadband 150, 250 or 500.

·; Enhanced, which supports up to nine simultaneous calls on an FB250 or FB500.

FleetBroadband users have two ways to access the multiple voice calling capability. Users of Thrane & Thrane SAILOR FleetBroadband terminals can create a fully-integrated solution with just a firmware upgrade and additional handsets. For other FB terminals, Vocality has developed new PBX hardware that can be used alongside the terminal to access the additional telephone lines.

"FleetBroadband Multi-voice is a unique integrated solution that maintains Inmarsat's well-earned reputation for high-quality voice," said Frank Coles, President, Inmarsat Maritime. "It offers a far superior service to internet calling solutions, and is more cost-effective than accessing multiple voice calls on a standard VSAT.

"This new capability increases the value of FleetBroadband, and ensures that the service is future-proofed for a vessel's growing communications needs."

FleetBroadband Multi-voice can be accessed on existing FleetBroadband equipment, and with the same per-minute tariff for both pre-paid and post-paid calls. It also supports the "505" emergency calling capability that connects a vessel immediately to a Maritime Rescue Centre.
