WIRELESS COMMUNICATION INTEGRATION DEVICE PREVENTING INTER-MODULATION DISTORTION

摘要

According to the present invention, disclosed is a wireless integration device for sharing wireless facilities. The wireless integration device according to the present invention comprises: multiple ports for inputting Tx signals and outputting Rx signals; an antenna port for outputting Tx signals and inputting Rx signals; a signal coupling and distributing means including a Tx coupling means for coupling multiple Tx signals respectively inputted through the ports, and an Rx distributing means for distributing Rx signals inputted through the antenna port; an inter-modulation distortion (IMD) preventing means for removing an IMD frequency generated when the Tx signals of different frequency bands are coupled in the Tx coupling means of the signal coupling and distributing means; and a TxRx coupling means installed between the signal coupling and distributing means and the antenna ports, and coupling the Tx signals and Rx signals. According to the present invention, when the Tx signals having different frequency are coupled in the wireless integration device, an IMD frequency overlapping an Rx band may be removed or occurrence thereof may be prevented. Thus, multiple communication providers can share the wireless facilities, so an integrated wireless service system can be constructed in a short time. In a national level, waste of resources caused by double investment can be prevented.
