A method includes determining whether information is to be transmitted via a radio frequency (RF) bus that supports direct intra-device communication between at least three circuits in a millimeter wave frequency band. When the information is to be transmitted via the RF bus, the method determines whether the RF bus is available. When the RF bus is available, the information is converted into RF bus signal, access to the RF bus is secured, and after access to the RF bus is secured, the RF bus signal is transmitted via the RF bus.
