  • Patent number: 11804892
    Abstract: Disclosed is an in-building distributed repeater technique for distributing a wireless mobile communication signal into a building. Mobile communication signals of service carriers in communication between devices of an in-building distributed repeater system may be converted into intermediate frequency (IF) signals with adjacent frequency bands and may be transmitted or received as analog signals with compressed bandwidths through frequency division multiplexing. The service band gap spacing of Tx downstream analog IF signals transmitted by a headend unit to a remote service unit is wider than that of Rx downstream analog IF signals received from an active antenna unit.
    Type: Grant

    Date of Patent: October 31, 2023
    Assignee: TJ INNOVATION Co., Ltd.
    Inventors: Young Man Cho, Gwangjae Jang, Judong Lee, Jinkyu Lee, Taeyoul Park, Jinsil Park, Duckyoung Park, Youngchul Baek
