Description
1.STA101はいつでもCFPに対するアクセス要求を送信するのにこのcchを使用することができるので、アクセス遅延が減少する。
2.2つの送信期間の分離が、IEEE802.11a/eの通常の時分割デュプレックス(TDM)方法ではなく符号領域において行われるので、予測不可能なビーコン遅延並びに同じチャネル上のCP及びCFPの動作からの衝突が、より容易に回避されることができる。
3.高いサービス品質(QoS)要件を持つSTA101(例えば、医療又は緊急アプリケーションにおいて使用されるSTA)は、送信遅延が保証されることができるCFPの時間を通して送信することができる。
