The present invention relates to fine-tuning a time delay of a relay device that distributes and relays a signal from a femto base station to many antennas by using an unshielded twisted pair cable (UTP). That is, by measuring a UTP time delay between a signal distribution device, which is a component of a UTP femto distribution and relay device, and a plurality of remote signal transmission and reception devices, respectively, a cable time delay between devices is corrected so that the plurality of remote signal transmission and reception devices may relay femtocell signals at the same time. A device for time delay fine-tuning UTP femto distribution and relay includes a signal distribution device that matches with a femtocell and measures a line delay between the signal distribution device and the remote signal transmission and reception device, and the remote signal transmission and reception device that feeds a signal from the signal distribution device back and accesses a terminal and a femtocell signal wirelessly. |
