Embodiments of a multi-radio platform with longer-range and shorter-range radio modules and method are generally described herein. Other embodiments may be described and claimed. In some embodiments, a transmit power level is set for transmissions by a shorter-range radio module during a reception by a longer-range radio module to a lesser of a maximum allowed power level or a next requested power level when transmit step-down mode is enabled. The transmit power level is set to the next requested power level when the longer-range radio module is not transmitting. The shorter-range radio module refrains from transmitting when a transmit-kill mode is enabled during the reception by the longer-range radio module.
