A system for transmitting contents with large data volumes comprising at least one stationary access point, each comprising at least one transmitting device for large transmission rates with a specific transmission range, at least one mobile unit comprising at least one receiving device for large transmission rates and being able to move into the transmission range of the access point, and a central controller which is configured to exchange control information with the access point and the mobile unit on at least one second data connection, wherein a transmission range of the second data connection is larger than a transmission range of the first data connection having a high bit rate, wherein a transmission rate of the second data connection is smaller than a transmission rate of the first data connection having a high bit rate, wherein the transmitting device of the access point and the receiving device of the mobile unit are configured to build up at least one wireless first data connection having a high bit rate for exchanging the contents when the mobile unit is within the transmission range of the transmitting device of the access point, wherein the transmitting device comprises a data provision storage and is configured to store, from a data network, contents for a transmission on the first data connection having a high bit rate, wherein the receiving device comprises a data buffer and is configured to store the contents received from the transmission on the first data connection having a high bit rate, and wherein the transmitting device of the access point and the receiving device of the mobile unit are configured to transmit data from the data provision storage into the data buffer via the first data connection having a high bit rate when the mobile unit is within the transmission range of the transmitting device of the access point, wherein the mobile unit is connected to at least one terminal and configured to transmit the contents from the data buffer to the terminal, wherein the control information transmitted by the mobile unit to the central controller and/or received by the mobile unit from the controller comprises control information about specific contents that are to be transmitted and/or information about a movement of the mobile unit, wherein the central controller is configured to determine, based on the control information, at least one access point in the transmission range of which the mobile unit might be located next and causes the at least one specific access point to keep the contents ready for a transmission. at least one stationary access point, each comprising at least one transmitting device for large transmission rates with a specific transmission range, at least one mobile unit
