Uhlelo lwe-Kingtone Fiber Optic Repeaters luklanyelwe ukuxazulula izinkinga zesignali yeselula ebuthakathaka, eshibhe kakhulu kunokusethwa kwe-Base Station entsha (BTS).
-
-Ukusebenza okuyinhloko kohlelo lwe-RF Repeaters:
Ukuze uthole isixhumanisi esiphansi, amasiginali 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.
Okwe-uplink, Ingabe inqubo yokuhlehla, amasiginali asuka kumakhalekhukhwini womsebenzisi afakwa 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.
- Isici esiyinhloko
- Izici Eziyinhloko◇ I-PA ephezulu yomugqa;Ukuzuza kwesistimu ephezulu;
◇ Intelligent ALC ubuchwepheshe;
◇ I-duplex egcwele kanye nokuhlukaniswa okuphezulu kusuka ku-uplink kuya ku-downlink;
◇ Ukusebenza okuzenzakalelayo ukusebenza okulula;
◇ Isu elihlanganisiwe elinokusebenza okuthembekile;
◇ Ukuqapha kwendawo nokukude (ongakukhetha) nge-alamu yephutha elizenzakalelayo &isilawuli kude;
◇ Idizayini evikela isimo sezulu yokufakwa kwesimo sezulu sonke;
- Uhlelo lokusebenza&izimo
- Izinhlelo zokusebenzaUkwandisa ukumbozwa kwesignali yendawo eyimpumputhe yesignali yokugcwalisa lapho isignali ibuthakathaka
noma engatholakali.
