Communication is described between integrated circuit packages using a millimeter-wave wireless radio fabric. In one example a first package has a radio transceiver to communicate with a radio transceiver of a second package. The second package has a radio transceiver to communicate with the radio transceiver of the first package. A switch communicates with the first package and the second package to establish a connection through the respective radio transceivers between the first package and the second package. A system board carries the first package, the second package, and the switch.
