Performance Improvement Method for Wi-Fi Networks Sharing Spectrum

We propose a solution that improves the performance of Wi-Fi networks sharing spectrum that are deployed in the same or adjacent area. The proposed solution uses the PS-Request protocol to sense the other Wi-Fi networks accurately, and manages the overlapped subcarriers in order to avoid the interference among the Wi-Fi networks sharing spectrum. The proposed solution can avoid the interference from the overlapped spectrum of Wi-Fi networks deployed in the same or adjacent region.
