The standard, they said, would help mobile network operators
improve the energy efficiency of their networks.
Telecommunications network operators, ETSI noted, are very
interested in improving the energy efficiency of their networks.
A press statement made available to ITRealms Online, ETSI
pointed out that besides the obvious environmental benefits, reducing energy
consumption makes good business sense, noteworthy is that in a mobile telecoms
network, the access network and in particular the Radio Base Station (RBS) is
the largest consumer of energy, and this is where most energy efficiency
improvements are focused.
ETSI explained that in order to improve energy efficiency,
one must be able to measure and compare levels of efficiency.
“This requires standardized measurement methods used across
the industry,” part of the statement read, adding that for this purpose, ETSI
has recently published the second edition of its technical specification TS 102
706 on the measurement method for energy efficiency of wireless access network
equipment.
This specification, developed by ETSI’s Technical Committee
for Environmental Engineering (TC EE), standardizes the measurement method for
energy efficiency for multiple mobile network technologies: GSM/EDGE,
W-CDMA/HSPA, LTE and WiMAX networks.
Also, ETSI said, the initial version of the specification
considered energy efficiency at three different static load levels (low, medium
and busy-hour traffic).
While the second version of this specification, ESTI
indicated, added the consideration of the dynamic behaviour of equipment in
operation with a realistic load level.
ETSI further identified two energy efficiency indicators for
wireless system, saying that one is based on the level of throughput compared
with energy consumed and the other is based on the coverage area compared with
energy consumed.
“This reflects the different demands placed on mobile
network operators: higher performance networks and increased wide-area
coverage,” the press statement read in part.
