COLLISION AVOIDANCE SYSTEMS AND METHODS

摘要

Disclosed herein are various embodiments of collision avoidance systems and methods. One method embodiment, among others, comprises a client sending an end of transmission (EOT) request to an access point (AP), and responsive to the EOT request, the AP responding with an EOT frame.

主权项

1. A method, comprising:
receiving a short frame preceding the start of a transmit opportunity (TXOP) from an access point (AP) to a wireless client at a basic rate to set a network allocation vector (NAV); transmitting and receiving a frame at the wireless client with the AP during the TXOP at a non-basic rate; and receiving a clear to send (CTS) frame from the AP at a basic rate that is configured to truncate the TXOP early, before the network allocation vector clears and prior to the end of the TXOP to avoid an extended interval frame space (EIFS) interval, wherein the basic rate is selected such that the frame from the AP reaches all nodes in a network to avoid the extended interval frame space (EIFS) interval.
