Signal transmission loss and power level
Coverage area ability
3
Note: FCC regulations limit the amplification of all cell phone boosters in order to
prevent damage to the telecommunications infrastructure. Therefore, the maximum
coverage area of a booster depends on the original power level of the signal captured by
the outdoor unit.
Notice: Not recommended when outdoor signal strength is less than -110dbm(3G/1x)
or -120dBm(4G/LTE). The resulting coverage area of the boosted signal will be
prohibitively small.
