    Hi guys
    How convert RxLev value into miliwatts?
    example: I have RX=-48 dbm in monitor of the mobile.

    I understand that RXLEV = P(dbm)+110
    and
    P(dbm) = 10*log(Pwr_IN_Watts/0.001)

    Please help

    Hi Jonh,

    P(dBm)=10lgP(mW)
    P(mW)=10^(PdBm/10)

    Thanks Kuma for your help

    This formula is used for P(dbm) negative in case of RX?
    Example = RX: -34 dbm

    Thanks

    The formula is same for negative values.
    -34 dBm (it is very good reception level)
    -34dBm/10 = – 3.4
    10^-3.4 = 0.000398 mW…

    You are welcome.
    There is one very good software for differenr kind of RF transformations. It is called calcucell. Give me you e-mail and i will send it to you.
    BR,
