扫描信道利用率
-
通道利用率%计算如下： Chan_util(in %)=(clear count 100)/cycle count
-
将此计算映射到 wifitool athX get_chan_survey 计数器： Chan_util(in %)=(busy*100)/total
-
Channel utilization% is calculated as: Chan_util(in %)=(clear count *100)/cycle count
-
To map this calculation to wifitool athX get_chan_survey counters: Chan_util(in %)=(busy*100)/total
