如果按平均功率算,也有100多mw, 不是你讲的几毫瓦。 这里有篇文章讲得很清楚。Power output ‐ peak output power,

maximum output power, or actual output power. Peak output
power is the phone s phone’s maximum maximum possible possible power level, whereas whereas maximum maximum output power is the
phone’s maximum power level within a network.  For instance, the peak output power of GSM can
be 1W or 2W, but because GSM only transmits for 1/8th of the call time and every 26th pulse is
omitted, the maximum output power is 120mW or 240 mW.11 For CDMA and UMTS technologies,
the transmission is continuous, and therefore the peak and maximum output power are the same
at 250 mW。
