Summary

通信事業者は中期的に大きな利益を得るだろうか？また5Gは、従来の機器サプライヤーへの依存を軽減するだろうか？フランスの調査会社イダテ社（IDATE）の調査レポート「新しいモバイルネットワークアーキテクチャの影響」は、以下の質問に答えます。

• 5G無線アクセスネットワークの仮想化により、事業者は中期的に利益を得ることができるか？
• 動的スペクトル管理は5Gにどのような影響を与えるか？
• 真の5Gへのゲートウェイであるスタンドアロン（SA）コアネットワークのスケジュールは？
• オペレーターは従来の機器サプライヤーに依存しなくなるか？ RAN市場の異端児は誰か？
• 米国からの新規参入者はRAN市場にどのような影響を与えるか？
• 5Gワイヤレスネットワーク仮想化の採用を先導しているのはどの事業者か。
