Companding Frequency Shifting Repeater

The remote village can’t receive the signal from town base station because of long distance. If we adopt the original signal frequency of 900MHz and 1800MHz, it’s easy to affect by the outside condition and the loss of wireless propagation path is biggish. Also the signal is easy to block off by the complicated Montana landform. So we need a system which uneasy to affect by outside condition and with powerful diffraction to transmit and cover, achieve large-scale wireless communication service to villages.
Typical Application:

The Villages’ Communication Project is mainly aim at the coverage of remote villages.
