Abstract

Embodiments of the present invention are directed to a wireless bus for intra-chip and inter-chip communication having adaptable links and routes among wireless-enabled components (WECs) of the wireless bus. Links and routes may be adapted according to one or more of, among other factors, the relative position of WECs, available capabilities (e.g., communication capabilities) at WECs, availability of resources at WECs, and the physical environment.
