Disclosed is a wireless communications integration device for radio equipment sharing. The wireless communications 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 unit which includes a Tx coupling unit coupling the Tx signals respectively inputted through the multiple ports, and an Rx distributing unit distributing the Rx signal inputted through the antenna port; an intermodulation distortion (IMD) preventing unit eliminating an IMD frequency, generated when Tx signals in different frequency bands are coupled by the Tx coupling unit of the signal coupling and distributing unit; and a Tx/Rx coupling unit installed between the signal coupling and distributing unit and the antenna port, and coupling a Tx signal and an Rx signal. According to the present invention, it is possible to eliminate an IMD frequency overlapping an Rx band or prevent generation of the IMD frequency when different Tx signals are coupled by the wireless communications integration device. The sharing of the wireless equipment of multiple communications service providers are realized, so implementation of an integrated wireless communications service system can be advanced, and, a waste of resources caused by double investments can be prevented on a national level. |
