On wireless networks, wireless radio, as the transmission media, is easily interfered by surroundings. The transmission quality of service data changes greatly depending on the interference. Therefore, you must evaluate and check the transmission quality of wireless links to ensure better service data transmission and efficient cooperation between densely deployed wireless networks, and reduces signal interference.
Use the RF ping function and exchange data packets between APs and STAs to check the transmission quality of wireless links. The link check result includes the signal strength, radio interface rate, packet sending delay, which can comprehensively indicate the transmission quality of wireless links.
