Millivolt to dbm conversion

    • Can MW and DBM be converted directly?

      Just like miles and kilometers can be converted directly, so can mW and dBm (of course, the mW-to-dBm conversion is from a linear scale to a logarithmic scale, and miles-to-kilometers would be linear-to-linear). A mW measurement is first converted to a base-10 logarithm.

    • Is dBmV independent of impedance?

      Inspection of Equation 1 shows dBmV to be independent of impedance. In the classic definition, dBµV is referenced to 1µVRMS and output voltage (VOUT) is measured inµVRMS (Equation 2). Since Equation 1 is a ratio of voltage, it can also be measured in µVP-P referencedto 1µVP-P or any voltage unit as long as the same units are used.

    • What if RSSI is less than 76 dBm?

      The Cisco device driver code indicates that if the RSSI value converts to less than –90dBm, then it should be converted to a fixed value of –75dBm. This leaves a question as to the exact interpretation of an RSSI value that converts to –76dBm to –89dBm. A measurement of –75dBm would be reported as 36% signal strength.

    • Can a Cisco card have less than 16 dBm?

      Bearing in mind that a Cisco card will have a Receive Sensitivity of –96dBm at its lowest, it is impossible to obtain an RSSI value of less than 16. Note, also, that all RSSI values greater than 93 are assigned –10dBm, and that there are multiple places in the table where two adjacent RSSI values are assigned the same dBm value.

      dBm Conversion Chart The most common measurement of RF signal levels is: ‘dB over a miliwatt (dBm)’. A signal level of '0 - dBm' equals '224 - millivolt (mV)' across '50 - ohm load'. A '0 - dBm' signal level in 'Power' is: Power (P) equals (=) Voltage (E) Squared divided (/) by Ohms ( );
