Annotation. Organization of mobile Internet on board of the aircraft is examined. Various ways of a “ground – aircraft” transport channel formation are analyzed and the use of laser communication in this capacity is proposed.

Introduction. Every year, mobile internet on board an aircraft becomes an urgent need, and in recent years, the situation with internet access on board an aircraft has improved significantly, despite the high cost and slowness of downloads. Many airlines provide access to the Internet on board at a very affordable tariff scale, while the options change dynamically and become more flexible, and some airlines even offer free of charge and for everyone to attract customers. This is due to the fact that organizing Wi-Fi on board of an aircraft is difficult and expensive. The main problem is the organization of the transport channel “land – aircraft”.


Formulation of the problem. There are two systems that provide the connection of the World Wide Web on board an airliner. One of them is called “Air-to-Ground (ATG)”, it involves the transfer of data “from air to ground” [3].

On the ground, there are base stations of cellular operators whose antennas are directed downwards; it is enough to provide additional antennas installed on the same towers, but directed upwards. In turn, it is necessary to place antennas on the bottom of the aircraft, and inside to provide a modem with special programs that allow communication with the airliner. An experimental Air-to-Ground system called DA2GC [1] is shown in Fig.1.
