Every Zigbee 3.0 device with routing capabilities (router or coordinator) must implement Green Power Basic Proxy (GPBP) v1.1.1 functionality for forward compatibility. GPBP enables routing devices to tunnel Green Power Device Frames (GPDF) from Green Power Source to Sink devices, making Green Power functionality possible on any Zigbee 3.0 network, regardless of a specific device's own application.
