    what does tx and rx mean

    Hi All,

    • Rx current 39mA
    • Tx current 39mA
    Should Rx and Tx current drawn be less to improve the power efficiency?

    • Receiver sensitivity -97dBm
    What does Decibels /meter mean?Should this be more negative for a better sensitive TX or RX?

    • Transmit power +3dBm
    Should this value be higher to have a better range(distance)?

    Thanks in advance

    Re: What does the following Tx and Rx specifications mean

    For RX/TX battery usage, 39mA is more than acceptable value.

    -97dBm represents a usual value for receiver sensitivity (negative is fine).
    dBm means:

    Yes, if TX power is greater than +3dBm you get better range. But the DC power consumption will be higher.
