2/17/2023 0 Comments Proxim wireless 8494If your 8494’s are “hearing” things 5dB better than your client which needs -65dBm, then your heat maps need to show where signal drops below -60dbm (-65 + 5 = -60). Well, when we are doing wireless surveys we are probably using third party adapters, just like the 8494’s, to mimic the devices/clients we are actually surveying for, because the clients themselves rarely provide the detailed RF statistics we need. For example, I assumed that all Proxim Orinoco 8494 adapters, probably the most popular WiFi test adapter for WLAN professionals, would have the same sensitivity because they are the same product, with the same components, made the same way, by the same manufacturer. I was already aware that different wireless devices had different ‘ Receiver Sensitivity‘, but I wrongly assumed that devices of the same model would have the same sensitivity.
