Abstract
Systems and methods resolve the hidden node problem in Wi-Fi communications and significantly reduce intra-extended service set (ESS) interference management and inter-ESS interference, thereby, improving network performance and enhancing user experience. In various embodiments, this is achieved by using connection discovery techniques that optimize user device associations with radio frequency (RF) units and streamline network management. Certain techniques leverage power detectors and timing references for efficient device identification and interference management. Further, some embodiments optimize multi-user multiple-input multiple-output (MU-MIMO) applications by improving user device selection and increasing areal capacity using two-antenna RF units.
