-
The exchange of data between the Internet and the at least one further sub-communication interface is via electromagnetic waves and via the at least one main communication interface within a range of the at least one main communication interface and the at least one secondary communication interface, usually dependent on the respective transmit power to perform.
-
The at least one main communication interface and the at least one sub-communication interface are compatible with each other. As soon as the at least one secondary communication interface is authenticated at the at least one main communication point, an exchange of the data between the at least one main communication interface and the at least one secondary communication interface is automatically feasible.
-
The communication system according to the invention comprises at least one main communication interface, which is arranged on a self-motor vehicle and designed for the exchange of data via electromagnetic waves and thus radio-supported and / or wireless. The at least one main communication interface is adapted to exchange data directly with the Internet, wherein the at least one main communication interface between at least one authenticated or legitimized external secondary communication interface, which is arranged outside the self-motor vehicle, and the Internet Data are to be exchanged indirectly.
