Abstract

The present invention relates to a bidirectional voice transmission system and a method thereof, wherein the system timing of the system is divided into three time slots for carrying a control signal, a broadcast voice signal and a mobile device voice signal. The bidirectional voice transmission system is able to carry out the signal transmission by way of frequency frogging, so as to effectively avoid the signal interference from occurring between any two different signal transmitting and receiving devices. Besides, all of the mobile devices can be added into the bidirectional voice transmission system by way of dynamic building, without using any specific communication interface. The most important is that, the number of node routers can be expanded to about 65,000 in order to apply the bidirectional voice transmission system in a huge range network communication or a wild rescue field.
