サマリー

フランスの調査会社イダテ社(IDATE)の調査レポート「グリーン5G:5Gの省エネ戦略」は、5Gの展開に、環境への配慮がどのように織り込まれているかを分析している。

5Gは、用途の拡大、新しい周波数帯の採用、従来のブロードバンドの枠を超えたネットワーク密度の向上を必要とするため、ネットワークの消費量を増加させる可能性が高い。その一方で多くのイニシアチブは、単位当たりの消費レベルを最適化することに焦点を当てている。

本レポートでは、エネルギー消費を削減および最適化するために設計されたいくつかのソリューション(AI、スリープモード、仮想化など)について考察する。また20社の市場プレーヤーの戦略を調査し、10社について詳細な分析を提供する。

 


 

Summary

This report analyses the ways in which environmental concerns are being factored into 5G rollouts.

It is highly likely that 5G will drive an increase in networks’ consumption, as it enables a growing number of uses, employs new frequency bands and requires increased network density, moving beyond the confines of classic broadband.
That said, a host of initiatives are focused on optimising per-unit consumption levels. This report takes a look at a number of solutions designed to reduce and optimise energy consumption (AI, sleep modes, virtualisation, etc.).

The world’s leading telecom manufacturers, equipment suppliers and operators are working to adopt these energy-saving solutions which, more and more, are being seen as selling points.
This report examines the strategies of some 20 market players, providing a detailed analysis for ten of them.

The report answers the following questions:

  • How will 5G change network consumption?
  • What are the main (current and future) avenues for reducing 5G’s consumption?
  • How are equipment suppliers tackling energy saving issues?
  • Which operators have the greenest strategic plans and most ambitious carbon-neutrality targets?
