voice and data
SwiftBroadband is an IP-based packet-switched service that provides a symmetric ‘always-
on’ data connection of up to 432kbps per channel. In Standard IP mode, the service
is shared with other concurrent users of the system, providing a “best effort” service.
SwiftBroadband can also provide a pre-determined quality of service through streaming
classes of 32, 64 or 128kbps. Higher bandwidth can be achieved by combining channels,
currently up to two per installation.
SwiftBroadband provides a high-quality voice channel with the full functionality of land-
based fixed phone services and a generic SMS service. For backward compatibility, it also
provides a circuit-switched ISDN service.
It is possible to have a combination of multiple packet-switched services with one circuit-
switched service active at the same time.
The end-user experience depends on the native performance of SwiftBroadband, as well as
any performance-enhancing technologies that are being used eg. data compression, IP and

For new aircraft, airframe manufacturers
can advise if SwiftBroadband avionics are
an option either as SFE or BFE. For aircraft
already in use, SwiftBroadband avionics
manufacturers can advise on recommended
Upgrading an existing Inmarsat installation

installed on the aircraft.
The minimum requirement is a software
upgrade, where the aircraft is equipped
with a ”SwiftBroadband-ready” installation.
If the avionics onboard the aircraft are

SwiftBroadband uses the narrow spot-beams of the Inmarsat-4 satellites. Initially accessible
over the Indian and Atlantic Ocean regions, it will be available globally, except the
extreme polar regions, following the successful launch of the third I-4 satellite.
