AI Technical Summary

Technical Problem

The lack of effective automatic frequency coordination (AFC) protocols in the prior art has resulted in inefficient use of 6GHz spectrum in wireless communication networks, especially in Wi-Fi networks where multiple Wi-Fi access points work together, and the use of spectrum cannot be optimized to avoid interference and improve throughput.

Method used

Spectral availability information is received and allocated through the network controller, coordinate wireless communications of multiple access points (APs) within the 6GHz spectrum, and determine AP location and spectrum availability using the FCC's AFC server and proxy server, and dynamically allocate channels to optimize network performance.

Benefits of technology

It realizes that in a wireless communication network within the 6GHz spectrum, the spectrum usage efficiency is improved, interference is reduced, network performance is optimized, data throughput is improved and latency is reduced.

Abstract

Techniques for using automatic frequency coordination (AFC for short) in a wireless communication network are described in the present invention. A network controller of a wireless communication network may receive spectrum availability information for operating a plurality of access points (APs) for Wi-Fi communications, the spectrum availability information being obtained by the plurality of APs according to a location of the plurality of APs or a location of the network controller. The network controller further configures a plurality of APs of the wireless communication network to perform Wi-Fi communication based on the spectrum availability information.
