Abstract
Embodiments provide systems and methods to optimize the time when to transmit a silencing frame, and hence, improve the overall network throughput and avoid access point transmission rate fall-back mechanism having an avalanche effect during coexistence of dissimilar wireless network technologies. A receiver comprises at least two dissimilar network technology subsystems, at least one subsystem of which is higher priority than at least another of the dissimilar subsystems. In some embodiments, a receiver is able to transmit a silencing frame during a predetermined transmission window within a lower priority technology network interval. In other embodiments, a receiver calculates a predetermined transmission window, the predetermined transmission window to occur within a lower priority technology network interval, and transmits a silencing frame during the predetermined transmission window. In further embodiments, a receiver is able to calculate a transmission window to occur during a lower priority technology network interval, and transmit a silencing frame during the calculated transmission window.
