[操作疑難] Router 點樣分辨接收靈敏度好唔好?

如下面兩個Router廠商的資料,我如果用1T1R的2.4g, N wifi 手指駁電腦,其實接收靈敏度差不多?

Router 1:
Support 2T2R, 2.4G, N & 5G, N + AC:
Reception Sensitivity - 2.4G:          11b: <-79dbm;
        11g: <-68dbm;
        11n: HT20<-65dbm HT40: <-61dbm
- 5G:         11a:<-68dbm;
        11ac: HT20<-65dbm HT40: <-61dbm HT80: <-51dbm

Router 2:
Support 1T1R, 2.4G, N
接收靈敏度        130M: -68dBm@10% PER
108M: -68dBm@10% PER
54M: -68dBm@10% PER
11M: -85dBm@8% PER
6M: -88dBm@10% PER
1M: -90dBm@8% PER
