Abstract
Some embodiments enable improved aggregated throughput and average latency in a wireless communication channel. Wireless electronic devices may implement adaptive contention window (ACW) channel access that improves channel capacity and enables latency sensitive applications (e.g., video streaming), especially when all wireless electronic devices operating on the channel as well as those in proximity utilize ACW channel access. Some embodiments detect when wireless stations on the communication channel as well as wireless stations in proximity are utilizing ACW channel access to obtain a transmit opportunity (TXOP). Based on the detection, an access point (AP) can instruct an associated wireless station to: use ACW channel access to obtain a TXOP, use a different channel access method obtain a TXOP as needed, disassociate and associate with a different AP, or use a different channel access method to obtain a TXOP.
