Wouldn't SNR play a bigger role than general signal level? What good is -67.8dBm if the noise floor is -75dBm?

It’s explained by the spec sheet of the current equipment and RX sensitivity. Basically the 450M AP can do more with less signal than the CPE can. Specs below. In any case we were then wondering what the new 450b RX sensitivity would be. There is a spec sheet on the Cambium website but this isn’t listed. Anyone have this information? 450M AP RX sensitivity 1x = - 93.5 dBm 2x = -88.6 dBm 4x = -81.5 dBm 6x = -75.9.0 dBm 8x = -67.8 dBm 450SM RX sensitivity 1x = -84 dBm 2x = -80.5 dBm 4x = -74 dBm 6x = -66.9 dBm 8x = -56 dBm 450i SM RX sensitivity 1x = -85.9 dBm 2x = -81.5 dBm 4x = -75.8 dBm 6x = -69.3 dBm 8x = -61.6 dBm Joe Falaschi e-vergent
