trends and propose realistic actions toreduce network energy consumption.To further optimize performance,together with the operator, we look at differentways to deploy, expand, restructure,upgrade, or migrate communicationsnetworks. We also explore implementingenergy-savings software and other features.Such solutions apply to building anew network, or expanding an existing one.We also offer the option to operate networkand energy-related infrastructureon behalf of operators. Our aim is to helpoperators reduce energy consumption,maximize efficiency, and improve networkavailability.Currently, about 240 million subscribersare served by networks for which Ericssonprovides Energy Management, as part ofManaged Services contracts. The serviceincludes around-the-clock, real-time monitoringof infrastructure and remote andon-site problem resolution for all, whetheror not they are connected to utility grids,along with ongoing energy- related optimizationto ensure energy is consumedin the most efficient manner.Partnering for greater reachAs a complement to Ericsson’s end-toendservice portfolio Ericsson has partneredwith the GSMA, the mobile industryassociation, on its Mobile Energy EfficiencyOptimization Service. The serviceundertakes site audits and equipmenttrials, analyses the costs and benefits ofspecific actions to reduce energy andemissions, and then works to implementthe most attractive solutions. This follows onfrom the GSMA Mobile Energy EfficiencyBenchmarking Service in which morethan 40 mobile network operators haveparticipated, accounting for more than200 networks and over half of globalmobile subscribers.Virtualized data centerData centers are important assets todeliver IT services, both for internal and forexternal use for most enterprises, includingoperators. They are often used to realizea cloud environment where many applicationsand users can share resources interms of computing, storage and network.Sharing resources between a number ofapplications and users enables a betterutilization, resulting in less overall need ofenergy-consuming hardware. For example,some applications are used moreduring the day; others more often at night.Cloud technology is therefore positive forenergy efficiency. An example from thetelecom world with a European mobileoperator shows that 60% energy reductionwas achieved when six locations for supportsolutions were consolidated into two,while still delivering the same capabilities.Ericsson’s data center offering has anumber of capabilities contributing tomore energy-efficient solutions. By usingthe latest generation of processors, it ispossible to increase system capacity by 20to 80% without any increase in power consumption.One example of an Ericssonsolution enabling virtualization and clouddeployments is the Ericsson Blade ServerPlatform (BSP) 8000, a family of bladeservers (electronic circuit boards containingmicroprocessors and memory) usedin telecom nodes. By introducing BladeServer Platform 8100 the power consumptionwill improve, compared to earlier hardwareconfigurations, as 20 to 200% moresubscribers can be handled with the samepower consumption.5G energy performanceEricsson is playing a leading role in developmentof next-generation 5G mobilecommunication systems, where keyrequirements and early concept developmentare now underway. A new generationof mobile communications technology is aunique possibility to introduce newrequirements and related capabilities.Energy performance, aiming at reducednetwork energy consumption, is one of thenew key requirements for 5G.First-round 5G research projects includethe EU-funded METIS 1) and 5GrEEn 2) .Standardization-related activities areexpected to start in 3GPP 3) during 2016.Energy performance in previous generationssuch as 2G, 3G, and 4G is focusedon moving from “always-on” to “alwaysavailable”network operation. 5G offers thepotential to take the next step to “alwaysoptimized.”Networks today, and in thefuture, will have to cope not only with hightraffic loads and coverage demands butalso with large traffic variations and lowaverage load. This calls for sufficient sleepmode possibilities to optimize energyperformance. Key means to achieve thisare advanced antenna techniques andultra-lean transmission 4) .RETHINK ENERGY PERFORMANCEApp coverageWhat is 5G?Among other things, 5G includes:> > 1000x higher mobile data volume> > 10 to 100x more connected devices> > 10 to 100x higher use data ratesSource: METISNodesSitesNetworksEnergy1) METIS - Mobile and wireless communications Enablers forthe Twenty-twenty Information Society.

Handling e-wasteresponsiblyThe key material streams Ericssondeals with are ferrous metals, preciousmetals and plastics. The majority of thesematerials eventually re-enter the commoditiesmarket where they are sold to industryas raw materials.Operators Airtel and MTN have partnered with Ericsson to help withthe disposal and recycling of electronic waste in Africa.We provide product take-backservices to our customers globallyas part of our Extended ProducerResponsibility.According to UN StEP (Solving the globalE-Waste Problem), by 2017 global e-wastewill reach 65.4 million tonnes, one-thirdhigher than in 2012.The European Union (EU) Waste fromElectrical and Electronic Equipment(WEEE) Directive has been in force since2005. However, we apply our proactiveapproach globally to address the risksassociated with WEEE. These risks includeimproper handling and treatment, transport,emissions, and human health risks.We conduct product take-back with recyclingpartners that meet our requirements,and are certified according to internationallyrecognized environmental and recyclingstandards.World-wide free of chargeOur program is available free of charge toour customers globally, not only in marketsrequired by law. For example, in 2014, customersAirtel Ghana and MTN Africa bothtook advantage of the program. Ghanahas one of the largest e- waste dump sitesin the world. Airtel has partnered withEricsson to help with the dis posal andrecycling of electronic waste in Ghana,including telecom equipment from theirnetworks at end of product life.We continue working closely with ourcustomers to ensure their e-waste is handledand treated in an environmentallysound manner. Ericsson’s ecology managementprogram has, since its start in2005, taken back e-waste from morethan 107 countries.Increased take-backWhen we take back our products, werecycle more than 98% of the materials.We continue to expand our ecology managementprogram involving more countriesand increasing take-back volumes forour customers. Product take-back andrecycling levels have increased significantly,from 9,800 tonnes in 2013 to15,900 tonnes in 2014.Revised targetCollection levels were below the 2014 targetcommitment level of 17% take-back,especially in non-legislated (i.e. non-EU)markets. We believe that this target wasoverly optimistic and have thereforereduced the target for 2015 to a globalcommitment average of 9%. We are also inthe process of revising our requirementsconcerning our ways of working and ourinternal processes in this area. Company-widetraining is also being prepared.We believe these changes will have a positiveimpact on achieving the 2015 targetand enable us to substantially increase thetarget from 2016 and onwards.Further, in order to address these challenges,we have initiated a campaign toraise awareness and engagement amongour sales staff, as well as customers. Forexample, Ericsson is working jointly withcustomer MTN Benin in an e-waste projectto take back telecom e-waste as well asmobile phones, personal computers andother household e-waste.Take back process – treated%10080604020020102011RecycledReuse20122013EnergyLandfill2014Source: EricssonObs!
