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)
