MULTI-IN MULTI OUT BASED IN-BUILDING RF SYSTEM AND METHOD, AND APPARATUS APPLIED TO THE SAME

摘要

A multi-in and multi-out based in-building rf system and a method, and apparatus applied to the same are provided to implement a mobile communication service at the in-building region supporting MIMO(Multi-In and Multi-Out) without the construction of the additional cable for the in-building RF system. An in-building RF system based on Multi-In Multi-Out comprises an in-building Radio Frequency Hub unit(200), a remote unit(300), and up down converter Amp Module unit(400). The in-building Radio Frequency Hub unit classifies the frequency of the more than two carrier signals provided from the base station(100). The in-building Radio Frequency Hub unit converts the frequency between the corresponding carrier signals in order to be differentiated. The in-building Radio Frequency Hub unit transmits the carrier signal of the frequency-converted to a cable within in-building.
