Mobile carriers are looking for ways to improve energy efficiency, PCWorld reports.
Reducing the cost of running mobile networks means reducing CO2 emissions, according to Gartner analyst Martin Gutberlet. Since mobile base stations consume almost 70 percent of all energy in a mobile network, increasing mobile equipment’s temperature threshold reduces the energy needed for air conditioning.
Nokia has said that it wants to cut energy consumption at some of its mobile base stations by up to 40 percent by 2010.
Ericsson’s radio base station site concept Tower Tube, for instance, is built using concrete instead of steel and is designed to require no active cooling.
Ericsson’s Base Transceiver Station Power Savings reduces energy consumption during off-peak hours by adapting the energy use of the base station and can lower energy use by 15 to 25 percent.
In 2008 Ericsson exceeded its target to lower energy use in a 3G base station by 50 percent compared to 2005 levels. Later this year it will introduce future targets.
Vodafone has announced it would reduce its carbon-dioxide emissions by 50 percent by 2020.
