Abstract:
A cascade-type multiplex radio communication relay system, in which a donor and a Main Hub Unit (MHU) are connected to each other through an Unshielded Twisted Pair (UTP) cable to enable duplex communication, and in which a plurality of remote units are connected to the MHU through UTP cables to enable duplex communication. The cascade-type multiplex radio communication relay system adopts a method of converting at least two different RF communication signals into a single UTP transmission frame, and relaying the UTP transmission frame through a UTP cable in a digital communication manner.
