MIMO テスト
Agilentは、測定業界のリーダーとして、MIMO無線機のトータルソリューションを提供しています。
MIMOとは送・受信それぞれに複数のアンテナを用い、スペクトラム効率を向上させるアンテナ・テクノロジーです。
- マルチパスなどの環境をうまく利用する技術であるため、環境要因を考慮した試験＝MIMO-フェージング試験が重要
- アンテナを複数にすることによりコストや複雑さが増大するため、MIMO送信に特有な試験が必要
- MIMOを採用する各無線規格は複雑で実装の仕方もさまざまなため、各規格に即したMIMO対応測定が必要
などの特徴があります。
MIMO共通の技術概要や各規格への実装方法については下記詳細欄もご覧ください。
