This EDNA report examines the power used for “network standby”. In the context of this report, network standby refers to functionality that allows a product to maintain a network connection and await a network “trigger” in order to be awoken when needed.

The report:

• Incorporates and organises our collective understanding of the network standby function
• Identifies the primary factors that influence its power draw
• Develops a framework for understanding these factors
• Estimates power ranges associated with different network standby function implementations.

After a comprehensive literature review and dialogue with key stakeholders, the report identifies 3 key factors that influence the power needs of the network standby function:

• The number and type of network interfaces
• The level of network interface functionality required during low-power modes
• The type of network traffic management strategies employed.
