THE MOBILE TELECOMMUNICATION REPEATER WHICH CAN CHANGE THE CENTER FREQUENCY AND BANDWIDTH OF ITS FILTER

摘要

A mobile communication repeater for varying a frequency and bandwidth is provided to operate the repeater flexibly according to the mobile communication environment by making the service-available band frequency variable. A repeater for the mobile communication comprises the followings: a means(14-1) for making the bandwidth and center frequency of a wave filter adjustable through the external control; and a means(16) for controlling the bandwidth and frequency by using information of a waveform detecting circuit. The repeater can be used without separately changing hardware by varying the repeater service frequency and band according to the mobile communication service environmental condition.
