Abstract
A system for evaluating available channels in a multi-channel WLAN telecommunication system is provided. The system includes a wireless Access Point (AP) configured to provide communication over a plurality of Very High Throughput (VHT) channels. The system further includes a plurality of mobile stations (STAs) operating in the plurality of VHT channels. The system further includes a network monitoring device. The network monitoring device is configured and operable to capture a plurality of VHT data frames exchanged between the wireless AP and the plurality of STAs. The network monitoring device is further configured and operable to decode at least a portion of each of the captured plurality of VHT data frames to identify utilized VHT channel and extract channel allocation information associated with the identified VHT channel and to generate a quality score for the identified VHT channel based on the extracted channel allocation information.
