1. a kind of transmission power of wireless signal in the wireless personal domain network WPAN with multiple frequency bands is adjustedMethod, the method include:

  • Read the power level of the wireless signal that measurement value sensor and determination are associated with the measurement value sensorChange;

    The change of the power level of the wireless signal is compensated,Wherein, the compensation includes:

    By being independently adjustable for driving the amplifier of the wireless signal for each frequency band in the plurality of frequency bandThe power level that gain arranges to adjust roughly the wireless signal;

    The voltage level of information signal of the amplifier is supplied to by adjustment accurately adjusting described in the wireless signalPower level, so that the power level of the wireless signal is close to maximum allowable power level,Wherein, described each frequency band being adjusted in the plurality of frequency band roughly provides different gains and arranges, and the essenceReally it is adjusted to the plurality of frequency band and gain is coequally provided, andWherein, the voltage level of the accurate adjustment described information signal is included via digital multiplier to being supplied to DACDigital baseband signal zoom in and out.
