Technologies are generally described for a bandwidth control scheme. In some examples, a transmitter device configured to transmit information via a wireless connection may include a baseband signal processor configured to process the information to generate a baseband signal with a baseband bandwidth; a modulator configured to modulate a radio frequency (RF) signal with an RF bandwidth based on the baseband signal; and a controller configured to adjust at least one of the baseband bandwidth and the RF bandwidth based on a movement of the transmitter device relative to a position of a receiver device configured to receive the RF signal.
