Abstract

A method is described for intelligently toggling request-to-send/clear-to-send (RTS/CTS) mechanisms on and off for a channel between an access point and a client device. In particular, the method may determine one or more characteristics related to the transmission of frames and toggle RTS/CTS based on these characteristics. The characteristics may describe (1) the airtime used to transmit frames, (2) the data rate used to transmit frames, (3) traffic measurements on the wireless channel between the access point and the client device, (4) overlapping basic service set traffic measurements, and (5) the number of data units included in frames to be transmitted. By toggling RTS/CTS on and off based on network/channel and frame conditions/characteristics, the method ensures that RTS/CTS is enabled when frame collisions are likely and/or channel capacity is low and disabled when frame collisions are unlikely and the overhead associated with RTS/CTS outweighs the potential benefits.

First claim

What is claimed is:

1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, cause performance of operations comprising to:
obtain characteristics related to transmission of a first set of data, wherein the characteristics comprise an actual transmission airtime for the first set of data relative to an ideal transmission airtime for the first set of data;
dynamically determine whether to transmit a particular f…
