Net-detect is an option of WoWLAN to allow the device to be woken up from suspend mode when configured network is detected. When user enables net-detect and lets the device enter suspend state, WoWLAN firmware will periodically scan until beacon or probe response of configured networks are received. If configured networks are detected, WoWLAN firmware will trigger resume process.
