SITAONAIR is a company that enables airline passengers to use their smart devices including mobile phones and laptops for calls, text messaging, emails and Internet browsing.

SITAONAIR (then OnAir) was the first company to provide integrated GSM and inflight wifi services, with Oman Air as the launch airline in March 2010.

[6] A satellite data unit (SDU) manufactured by Thales and branded TopConnect establishes a backhaul link to the ground through Inmarsat's SwiftBroadband geostationary satellite constellation operating in the L band around 1500 MHz which allows the use of electronically steerable antennas mounted atop the aircraft fuselage and encased within a fiberglass, RF-transparent radome, that have a low profile compared to systems operating in the Ku band or Ka band which today still require mechanically steerable antennas with a significantly higher profile.

Inmarsat's SwiftBroadband system covers much of the planet except for the polar regions above −82 and below +82 degrees latitude and currently provides symmetric data rates of up to 432 kbit/s per channel dependent on signal quality and overall load on the satellite's spotbeam serving the corresponding geographical area.
