Today we use RSSI as indicator of AP quality. However even if you have
rssi=-45dm it's not enough to say that AP WiFi guarantees you good BW. Because if many clients connected to the same AP and some of them have the same channel the
RSSI still will be good but actually we get low BW (throughput).
For that reason I try to fetch SNR or Noise from AP. The problem is - for mobiles like Android and iOS we can't get nor SNR neither Noise. I have only
RSSI and AP
For that reason I try to find any correlation between SNR and Link Speed.
Any suggestions, documents?
