S T R A T E G I C W H I T E P A P E R Using air-to-ground LTE for in-flight ultra-broadband Opening the skies to new possibilities This paper covers both the business and technical considerations for ultra-broadband connectivity in continental aircraft fleets, and the benefits of a terrestrial cellular network approach based on 4G LTE. It describes the specifications and results of unique live experience gained in field trial campaigns of an air-to-ground prototype system, and offers go-forward considerations for telecom or satellite operators, airlines and business aviation stakeholders looking to gain competitive advantage in their service offerings.
