Wi-Fiオフロード:モバイルネットワークにおけるキャパシティオーバーレイとしてのWi-Fiのコストとメリット The Case for Wi-Fi Offload: The Costs and Benefits of Wi-Fi as a Capacity Overlay in Mobile Networks
出版日: 2011年12月23日 ページ情報: 英文 PPT (58 slides); Excel
概要

モバイルデータトラフィックの需要とギガバイトあたりの収益の下落により、通信事業者はネットワークキャリッジコストを削減し、利益を確保する手段の模索を余儀なくされています。満足な利益を取り戻すためには、RANにおいて適切な技術構成を選択し、データ転送コストを半減させる必要があるでしょう。

当レポートでは、モバイルデータトラフィックの拡大に対応するためのWi-Fiオフロード戦略について調査分析し、無線アクセスネットワーク機器のコスト分析、キャパシティオーバーレイとしてのWi-Fi導入における課題などをまとめ、概略下記の構成でお届けいたします。

調査内容

  • 2011-2016年に西欧で52%のモバイルデータトラフィックの拡大に対応するための無線アクセスネットワーク機器コストの詳細分析
  • 混雑した都市部のシングルサイトエリアでLTE・屋外Wi-Fi・屋内Wi-Fiを利用して52%のモバイルデータトラフィックの拡大に対応するためのコストの詳細分析
  • 屋外Wi-Fiアクセスポイント・屋内Wi-FiアクセスポイントのOPEX・CAPEXの分析
  • キャパシティオーバーレイとしてWi-Fiの導入を考える通信事業者が直面しているオペレーションおよび戦略上の課題のレビュー
目次

To return to acceptable margins, operators need to cut by half the cost to deliver data - selecting the right technology mix in the RAN is key to achieving this.

The demand for mobile data traffic and falling revenue per gigabyte is forcing operators to seek ways to reduce network carriage costs and to restore margin. This Report not only shows this cost can be reduced by 80% using indoor Wi-Fi, it also discusses the operational challenges that operators will have to overcome to deploy Wi-Fi.

This Report provides:

  • detailed analysis of the cost in radio access network equipment to deliver 52% mobile data traffic growth in Western Europe during the period 2011 to 2016
  • in-depth analysis of the cost to deliver 52% mobile data traffic growth to a single site area in a congested urban site using LTE; outdoor Wi-Fi and indoor Wi-Fi
  • an analysis of the opex and capex costs for outdoor Wi-Fi access points and indoor Wi-Fi access points
  • a review of the operational and strategic challenges facing operators that might wish to deploy Wi-Fi as a capacity overlay.
