Introduction to Green Power#
Zigbee Green Power (ZGP) is included in the Zigbee 3.0 specification (Z3) Zigbee Alliance, Zigbee 3.0 specification. It is an end-to-end open standard that allows ultra-low power devices called Green Power Devices (GPDs) to operate on Zigbee networks.
Green Power is actually a number of technologies combined into one global standard that includes these features (Zigbee Green Power, Cam Williams):
Energy harvesting technology.
Includes mechanical, heat, light, pressure (piezo), and other energy harvesting technology.
Ultra-low power RF silicon that uses many orders of magnitude less power than required for a sleepy or fully networked wireless connection.
Uses ultra-low power, non-volatile memory such as Ferroelectric RAM (FRAM).
An open, global standard network technology that saves even more energy by reducing packet length, round trips, connection rediscovery, and on-network time for devices that may be offline for extended periods of time.
Zigbee – 15.4 – 2.4Ghz modules
An open, global, standard application layer protocol that supports compressed messages and limited transactions using:
Zigbee Application Framework (AF)
Zigbee Cluster Library (ZCL)
