技術者は、重複しないチャネルで MIMO を利用するワイヤレス接続を設定する必要があります。 次のどれが最良の選択でしょうか?
正解:D
The 802.11n standard supports MIMO (Multiple Input Multiple Output), which allows multiple antennas to increase data throughput and improve reliability. Additionally, it uses non-overlapping channels in the 5 GHz band (and optionally the 2.4 GHz band), making it a good choice for high-speed, interference-resistant wireless connections.
