Intro
19、duction Up until now, broadband services have mainly been provided using fixed (VDSL or optical) or mobile (3G or LTE) networks. However, satellite networks are now becoming able to provide broadband services of similar bandwidth and response times to those from terrestrial networks, especially with
20、 the introduction of new hybrid satellite networks where alternative paths can be selected depending on the bandwidth and response times required. It is therefore useful to be able to assess the energy efficiency of satellite networks and compare this on an equivalent basis to the energy efficiency
21、of terrestrial networks. Energy efficiency is also a growing concern in the design of satellite networks and there are increasing efforts to minimize the energy consumption of SatCom systems, especially in the ground segment where most terminals have been designed to operate on an always-on basis. B
22、y carrying out an assessment of the energy efficiency of a satellite network, the subsystems and components that have the most impact can be identified and attention paid to reducing their energy consumption. In particular, given the relatively large numbers of satellite terminals in operation, thei
23、r impact can be identified compared with that of the other subsystems and appropriate measures taken to improve their energy efficiency. ETSI ETSI TR 103 352 V1.1.1 (2016-06) 5 1 Scope The present document reviews the assessment of energy consumption during the operational phase of satellite network
24、s, and identifies whether additions are required to the general assessment methodology developed in ETSI TS 103 199 i.10. It also reviews the energy efficiency related metrics developed for terrestrial wireless and mobile networks in ETSI TR 103 117 i.7 and identifies any necessary adaptations to en
25、able the methodologies to be applied to satellite networks. Satellite Networks allow broadband services to be delivered to approaching 100 % of the population, even in remote areas, and can therefore be used to fill gaps in the coverage of other access technologies. Broadband services can be offered
26、 to residential or business customers via satellite in a cost effective manner compared to other methods of services provisioning. However, their energy consumption needs to be assessed and compared with other ways of delivering broadband services. 2 References 2.1 Normative references As informativ

45、umber of directives to foster energy efficient design of products: Directive 2005/32/EC on 6thJuly 2005 i.18 establishing a framework for the setting of eco-design requirements for energy-using products.

Directive 2010/30/EU on 19thMay 2010 i.20 on the indication by labelling and standard product information of the consumption of energy and other resources by energy-related products. In parallel with this, the EU have defined a series of voluntary Code
47、s of Conduct (CoC) which specify annual targets for reductions in electricity consumption of different types of equipment. The CoCs relevant to satellite broadband networks are: CoC on Energy Consumption of Broadband Equipment i.1: This sets targets for reducing the energy consumption of equipment s
48、uch as broadband modems and home gateways. Equipment on both the consumer side (end-use equipment) and the network side (network equipment) is covered for any service providing a two-way data rate of 144 kb/s or above. Several operational states are defined for each type of equipment (e.g. full load
49、, low load and standby) with typical targets of 0,3 W for a fast ethernet port in the idle state, reducing to 0,2 W in 2013-2014. CoC for Digital TV Systems (Set-Top Boxes) i.2: This covers complex set top boxes (STBs) and similar equipment for the reception, decoding, recording and interactive processing of digital TV and related services accessible through a Conditional Access system. This gives targets for annual energy allowance of 60 kWh/year for a Satellite STB, falling to 53 kWh/year on 1 January 20
