SwiftBroadband[1] is an IP-based packet-switched communications network that provides a symmetric ‘always-on’ data connection of up to 650 kbit/s[2] per channel for aircraft globally except for the polar regions, using the Inmarsat satellite constellation.
[8] For Standard IP service, the throughput that an end-user experiences depends on the load on the channel as well as other factors such as antenna type and data compression.
Traffic prioritization is available through Flightstream SA to make sure high priority data reaches the Satcom terminal even in situations where 100% of the allocated downstream network bandwidth is being used.
[10][11][12][13] In October 2013 Inmarsat announced the launch of its new SwiftBroadband High Data Rate (HDR) streaming service for the aviation market which provides a guaranteed bandwidth (QoS) of est.
[26] Flightstream AOC service incorporates a number of technologies to reduce the data usage by up to 80% over the satellite network and provides a better overall experience (faster page loads) for the end user by utilizing advanced acceleration, optimization and compression designed to account for latency and packet shaping considerations specific to satellite communications.
