Scope
L.1310 specifies the principles and concepts of energy efficiency metrics and measurement methods for telecommunication network equipment including small networking equipment used in the home and small enterprise (less than 12 ports and Wi-Fi) and RAN.
Summary
L.1310 contains the definition of energy efficiency metrics, test procedures, methodologies and measurement methods required to assess the energy efficiency of telecommunication network equipment.
The proposed metric for Radio Access Network (RAN) includes GSM (2G), UMTS (3G) and LTE (4G). It focusses on calculating the Radio Base Station (RBS) energy efficiency, based on the argument that RBS energy consumption is the dominant part of the total energy consumption of a wireless access network. Low, medium, and high load modes are defined for the RBS usage profile (Idle mode and max load cases are omitted).
The proposed energy efficiency metric at RF unit level is given by:
Eoutput is daily RF output energy consumption [Wh] under different loads.
ERFU is daily RF units energy consumption [Wh] under different loads.
Where:
PBH, output, Pmed, output and Plow, output [W] are RF output power under three different load levels defined for static scenarios in [ETSI ES 202 706-1] and for dynamic scenario in [ETSI TS 102 706-2]; PBH, RFU, Pmed, RFU and Plow, RFU [W] are the power consumption of RF units under three different load levels; tBH, tmed and tlow [hour] are durations of different load levels during a day.
The adopted metric for small networking devices used in home or small office is the Energy Efficient Rating (EER) based on the throughput performance, T:
Power shall be averaged over 5 minutes, taking measurements every 30 seconds. During idle power, IP pings shall be sent via the user interface.
Relevance for EXIGENCE
The definitions, metrics, and methods for EE (RBS and home/small office devices) are relevant for energy metrics and energy measurements.
