Gogo offers WiFi Internet access on American Airlines domestic flights within United States. The Internet services are provided through Air-To-Ground (ATG) technology: a cellular radio network of over 200 towers in North America points their antennas to the sky; a Gogo-equipped airliner connects to one of these cellular towers, and provides Internet to passengers via WiFi. Pricing for Internet access via Gogo in-flight WiFi starts at USD 4.95 for 30 minutes.
American Airlines and Gogo also provide inflight personal device entertainment through the same
gogoinflight Wi-Fi signal.
This service is free of charge, and allows passengers to watch movies and TV episodes on their own smartphones and tablets.
Presumably, contents are pre-downloaded to a server located inside the aircraft, and therefore accessing those contents do not consume radio bandwidth.
While watching videos are permitted during the flight, Gogo does not want passengers to download these copyrighted movies for watching later at home. Therefore, users must have the Gogo Entertainment app on their mobile devices in order to watch movies. The app is compatible with the Digital Rights Management technology used in the entertainment server, to ensure that the movies can be watched for free, but cannot be (easily) downloaded. But what if the device does not already have the Gogo Entertainment app?
