They provide connectivity to the public Internet via a Wi-Fi hotspot accessible from the cabin of the aircraft. This in-cabin network may also be used to provide in-flight entertainment services ranging from television network feeds to movies and canned TV shows available from an on-board media server connected to the network. In the U.S., the Internet connectivity is available when the aircraft is above 10,000 feet and is turned off during take-offs and landings... Gogo, the current market leader, provides connectivity to aircraft via a network of 250 dedicated cell towers that it has built nationwide. Fundamentally, it offers the same type of connectivity you would expect to see on a standard 3G capable phone. The connection is limited in speed to just over 3 Mbps — and all users on the plane share this one connection.""
