A wireless device may transmit a message during a transmit opportunity (TXOP) that includes a first portion transmitted at a first data rate and a second portion transmitted at a second rate that is higher than the first. The wireless device may then transmit a terminating message at the first data rate. The wireless device may also receive a second message prior to transmitting the terminating message. The terminating message may be a clear-to-send message (CTS) or an acknowledgement (ACK) message. The first message may be an aggregate media access control packet data unit (A-MPDU) in which the first portion is a preamble and the second portion is an MPDU."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Avoiding extended interframe space","description":"Methods, systems, and devices are described for avoiding extended interframe space (EIFS) in a wireless local area network (WLAN).
