I-China Kingtone 400MHz UHF I-Tetra Optic Repeater BDA System Nweba Ukufakwa Nge-Fiber Optic Ngokwakhiwa Kwangaphakathi Kwehhotela Elikhulu

Isistimu ye-Kingtone JIMTOM® Fiber Optic Repeaters yakhelwe ukuxazulula izinkinga zesignali yeselula ebuthakathaka, eshibhe kakhulu kunokusethwa kwe-Base Station entsha (BTS).Ukusebenza okuyinhloko kohlelo lwe-RF Repeaters: Ukuze uthole isixhumanisi esiphansi, amasignali asuka ku-BTS aphakelwa ku-Master Unit(MU), i-MU bese iguqula isignali ye-RF ibe isignali ye-laser bese iphakela ku-fiber ukuze idluliselwe ku-Remote Unit(RU).I-RU bese iguqula isignali ye-laser ibe isignali ye-RF, futhi isebenzisa Isihlelamandla ukuze ikhulise amandla aphezulu ku-IBS noma i-antenna yokumboza.Ukuze uthole isixhumanisi saphezulu, Ingabe inqubo yokuhlehla, amasiginali asuka kumakhalekhukhwini womsebenzisi anikezwa echwebeni le-MU le-MS.Nge-duplexer, isignali ikhuliswa isikhulisi somsindo ophansi ukuze kuthuthukiswe amandla esignali.Bese amasiginali anikezwa i-RF fibre optical module bese iguqulelwa kumasiginali ye-laser, bese isiginali ye-laser idluliselwa ku-MU, isiginali ye-laser esuka ku-RU iguqulelwa kusiginali ye-RF nge-RF optical transceiver.Bese amasiginali e-RF akhuliswa abe amasiginali wamandla engeziwe anikezwa i-BTS.

I-RF Repeater yakhelwe ukuthuthukisa ukumbozwa kwenethiwekhi yamaselula futhi igcwalise izindawo eziyimpumputhe.Ukusebenza okuyinhloko kwesiphindaphinda ukuthola isignali yamandla aphansi evela ku-Base Station (BS) ngokudluliswa kwefrikhwensi yerediyo (RF) nge-antenna yayo yokunikela, inqubo, ikhulise futhi idlulisele isignali ku-Mobile Station (MS) endaweni eqondiswe kuyo ngenkonzo yayo. uthi.

Izici Eziyinhloko

• Ubuchwepheshe be-FPGA Base SDR, Ukucijwa kwebhendi ukuthola ukwenqatshwa;
• Ukuqapha kwangaphakathi okuhlakaniphile, kulula ukuthola amaphutha ukuze kugcinwe;
• Ukusetshenziswa kwamandla okuphansi, ukuchithwa kokushisa okuhle kakhulu;
• I-PA ephezulu yomugqa, inzuzo ephezulu yesistimu;
• Ukuqapha kwasendaweni nokukude (ongakukhetha) nge-alamu yephutha elizenzakalelayo &isilawuli kude;
• Usayizi ohlangene, oguquguqukayo ukuze ufakwe futhi uthuthwe;
• Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
• I-MU eyodwa ingashayela i-Max 32 RUs, Yonga izindleko futhi wenze lula ukufakwa.
• Indandatho yokusekela, iketango le-daisy, i-topology yenkanyezi, thuthukisa ukuguquguquka kwenethiwekhi.
• Idizayini yezinkampani eziningi, abathwali abakhulu abayi-16, Bamba kalula izimo zohlelo lokusebenza lwethrafikhi ephezulu
