Inkqubo ye-Kingtone Fiber Optic Repeaters yenzelwe ukusombulula iingxaki zesiginali yeselula ebuthathaka, enexabiso eliphantsi kakhulu kunokuseta iSikhululo esitsha seSiseko (BTS).
-
-Ukusebenza okuphambili kwe-RF Repeaters system:
Kwikhonkco elisezantsi, iimpawu ezisuka kwi-BTS zondliwa kwiYunithi eyi-Master(MU), i-MU emva koko iguqule isignali ye-RF ibe ngumqondiso we-laser emva koko ifake ifayibha ukuze idluliselwe kwi-Remote Unit(RU).I-RU ke uguqule isiginali yelaser ibe ngumqondiso weRF, kwaye usebenzise iAmplifaya yaMandla ukukhulisa amandla aphezulu kwi-IBS okanye i-eriyali yokhuselo.
Kwi-uplink, Ngaba yinkqubo ebuyela umva, imiqondiso evela kumsebenzisi weselula ithunyelwa kwi-MU's MS port.Nge-duplexer, isiginali yandiswa ngesandisi-lizwi esisezantsi sokuphucula amandla omqondiso.Emva koko imiqondiso ifakwa kwi-RF ifayibha imodyuli yokukhanya emva koko iguqulelwe kwiimpawu ze-laser, emva koko isiginali yelaser idluliselwe kwi-MU, isiginali ye-laser esuka kwi-RU iguqulelwa kwisiginali ye-RF nge-RF optical transceiver.Emva koko imiqondiso yeRF iye yandiswa ukuya kwiimpawu zamandla ezongeziweyo ezifakwe kwi-BTS.
- Eyona nto iphambili
- Iimpawu eziphambili◇ Ulandelelwano oluphezulu PA;Ukuzuza kwenkqubo ephezulu;
◇ Ubuchwephesha be-ALC obukrelekrele;
◇ I-duplex epheleleyo kunye nokwahlukaniswa okuphezulu ukusuka kwi-uplink ukuya kwi-downlink;
◇ Ukusebenza okuzenzekelayo ukusebenza kakuhle;
◇ Ubuchule obudityanisiweyo kunye nokusebenza okuthembekileyo;
◇ Ujongo lwasekhaya kunye nolukude (ukhetho) nge-alam yempazamo ezenzekelayo & nolawulo olukude;
◇ uyilo lokumelana nemozulu kufakelo lwemozulu yonke;
- Isicelo&imeko
- UsetyenzisoUkwandisa ukugutyungelwa komqondiso wophawu lokuzalisa indawo eyimfama apho umqondiso ubuthathaka
okanye ayifumaneki.
