Hi community, From my research, there are 2 ways to measure signal strength: RSSI - Received Signal Strength Indicator (usually 0-60 or 0-255,...). dBm - Decibels in relation to a milliwatt (usually -30 to -100). Different vendor goes with different way to measure signal strength collected by their APs. I think Meraki APs uses RSSI since I saw positive signal strength values in our data. I saw a document [*] which shows conversion (from RSSI to dBm) for Cisco device as follows: 0 = -113 1 = -112 2 = -111 3 = -110 4 = -109 ... 92 = -13 93 = -12 94 = -10 95 = -10 96 = -10 97 = -10 98 = -10 99 = -10 100 = -10 The above conversion applied when range of RSSI is from 0 - 100. My question are: Does anyone know if the above conversion table is correct (I understand it cannot be 100% accurate)? Is there any other way to convert RSSI to dBm? If Meraki is using RSSI, what is the range of value? Is it 0-100? Thank you, Daniel [*] source: https://d2cpnw0u24fjm4.cloudfront.net/wp-content/uploads/Converting_Signal_Strength.pdf
