802.11 MAC
- MAC結構基於邏輯整合功能決定誰和隨時能使用這無線媒介。它支援分裂和加密並且作為在邏輯鏈路控制次層(LLC)和PHY層之間的一個界面。
- 除IEEE 802.11e 提供的區別和優先順序化之外,輸送機會(TXOP),多路系統資料架構能從一站(STA)傳送到另一個的一段時間間隔,也稱做bursting(塞滿爆炸)-也介紹為一個改進MAC 效率的方法 。
- 隨者結構爆發,確認信號(認可字元)(ACK)的另一種類型 ,如同所知的block ACK,被建立以讓接收者能使用單一廣泛的ACK結構來充分有經濟效益的確認多路系統收到的資料架構。運輸流量具有交通標識識別符號(TID)以及一套說明通信的QoS需求的訊息的交通詳述(TSPEC)結構的特性。
