Telecommunications energy efficiency ratio

The Alliance for Telecommunications Industry Solutions (ATIS) has published three standards for determining telecommunication equipment’s energy efficiency. The standards introduce the Telecommunications Energy Efficiency Ratio (TEER) as a measure of network-element efficiency. ATIS is 'the leading technical planning and standards development organisation committed to the rapid development of global, market-driven standards for the information, entertainment and communications industry'.

The standards provide a methodology for measuring and reporting energy consumption and quantify a network component’s ratio of 'work performed' to energy consumed. The efficiency standards are specific to equipment type, network location and classification, but normalising by functionality enables like-for-like comparisons.

Currently there are three standards defining TEER’s General Requirements, Transport Equipment TEER, and Server Equipment TEER, but a lot more are expected, including routers, power rectifiers and wireless access equipment.
