Method, device and system for the transmission of data from a data transmitter to a server

A device for the transmission of data from a data transmitter to a server with at least one predetermined quality-of-service level, the data being transmitted by means of a cellular network using frequency sub-bands, wherein the device comprises circuitry causing the device to perform:

• selecting, by a modem of the device, of at least one sub-band from among the frequency sub-bands of the frequency plane enabled for the transmission of data to the server,
• obtaining at least one selected frequency sub-band,
• obtaining information representing the quality of service of the connection between the transmitter and the server,
• checking whether the information representing the quality of service of the connection between the transmitter and the server is superior to or equal to a predetermined quality level,
• transferring data to the server if the information representing the quality of service of the connection between the transmitter and the server is superior to or equal to the predetermined quality level,
• notifying to the modem a prohibition of selection of at least one previously selected frequency sub-band if the information representing the quality of service of the connection between the transmitter and the server is not superior to or equal to the predetermined quality level,
• activating the selection, obtaining and notification means as long as the information representing the quality of service of the connection between the transmitter and the server is not superior to or equal to the predetermined quality level.

• checking by the transmitter, whether the information representing the quality of service of the connection between the transmitter and the server is superior to or equal to a predetermined quality level,
• transferring by the transmitter of data to the server if the information representing the quality of service of the connection between the transmitter and the server is superior to or equal to the predetermined quality level,
• notifying, by the transmitter to the modem of a prohibition of selection of at least one previously selected frequency sub-band if the information representing the quality of service of the connection between the transmitter and the server is not superior to or equal to a predetermined quality level,
• activating by the transmitter the selecting, obtaining and notifying means as long as the information representing the quality of service of the connection between the transmitter and the server is not superior to or equal to the predetermined quality level,
• notifying by the server of an absence of reception of data from the transmitter.
