Apparatus, method, and computer program for frequency band selection

A motor vehicle including an apparatus for controlling a frequency band selection for wireless communication with a mobile station in a wireless local area network, wherein at least a first and a second frequency band are selectable, wherein the first and second frequency bands each comprise a multiplicity of transmission channels;

• the apparatus comprising:
• a transmission circuit for transmitting at least one command to the mobile station that asks the mobile station to change a data exchange connection with the apparatus from the first to the second frequency band, and
• a provision circuit for providing results of a Dynamic Host Configuration Protocol procedure between the mobile station and the apparatus before the change from the first to the second frequency band, that continue to be used after the change from the first to the second frequency band,
• and a control circuit connected to a two-way circuit, which stores an identifier of the mobile station and frequency band aspects specific to the mobile station so that a change of frequency band that is not possible for the mobile station is prevented from being repeatedly initiated,
• wherein the apparatus is arranged so that the whole interior of the motor vehicle is available for spatial positioning of the mobile station for a communication with the apparatus.
