    Transmit power of base station much larger than the mobile phone, can calculate the base station coverage distance from the calculation of the propagation attenuation of the reverse circuit. But in the actual installation and measured of the repeater, can also estimate the distance be the signal strength that phone received from base station , micro-repeater location of the signal around -100dBm, if not install micro-repeater, the communication sometime contect sometime stop, The effect very bad, it will be a significant improvement for 1-3km road signals, after installing the micro-repeater.
