Abstract
The invention provides a method and system for assigning one or more optimal wireless channels to a Wi-Fi access point of a plurality of Wi-Fi access points using a cloud-based orchestrator through a software defined network (SDN). To start with, RF measurements are collected from a plurality of client devices in the cloud using a RF measurement module. The RF measurements include received signal strength indicator (RSSI) measured by the plurality of client devices and a transmission channel from connected or nearby Wi-Fi access points. The one or more optimal wireless channels for the Wi-Fi access point are then derived by solving a complex optimization problem. This process employs an artificial intelligence (AI) module integrated with a global continuous optimization algorithm. The AI module utilizes the collected RF measurements and a plurality of measured variables for determining the one or more optimal wireless channels for the Wi-Fi access point using the optimization formulation.
