Abstract

Disclosed herein is a roadside unit with a radio frontend port configured to receive a first signal representing a radiofrequency transmission according to a first radio communication protocol, to receive a second signal representing a radiofrequency transmission according to a second radio communication protocol. A first processing subsystem configured to execute a first baseband process of the first radio communication protocol on the first signal and to generate a first output signal as an output of the first baseband process. A second processing subsystem configured to execute a baseband process of the second radio communication protocol on the second signal and to generate a second output signal as an output of the second baseband process. The first processing subsystem is a first software containerization or a first machine virtualization of the processor, wherein the second processing subsystem is a second software containerization or a second machine virtualization of the processor.
