Inkqubo ye-Kingtone Repeaters yenzelwe ukusombulula iingxaki zesignali yeselula ebuthathaka, enexabiso eliphantsi kunokongeza iSikhululo esitsha seSiseko (BTS).Umsebenzi ongundoqo we-RF Repeaters system kukufumana umqondiso wamandla aphantsi osuka kwi-BTS ngosasazo lwamaza kanomathotholo emva koko usasaze umqondiso owandisiweyo kwiindawo apho unxibelelwano lwenethiwekhi lunganelanga.Kwaye isiginali yeselula nayo ikhulisiwe kwaye idluliselwe kwi-BTS ngendlela echaseneyo.
I-Kingtone Fiber Optic RF Repeater sisisombululo esithembekileyo sokwandisa nokuphucula indawo yokugubungela inethiwekhi ye-TETRA 800MHz.
- Uphawu oluphambili
- Iimpawu eziphambili ze-Repeater:
Umgca ophezulu we-PA;Ukuzuza kwenkqubo ephezulu;
Itekhnoloji ekrelekrele ye-ALC
I-duplex epheleleyo kunye nokwahlukaniswa okuphezulu ukusuka kwi-uplink ukuya kwi-downlink;
Ukusebenza okuzenzekelayo ukusebenza kakuhle;
ubuchule obudibeneyo kunye nokusebenza okuthembekileyo;
Ujongo lwasekhaya kunye nolukude (ukhetho) nge-alam yempazamo ezenzekelayo & nolawulo olukude;
Uyilo lokumelana nemozulu yofakelo lwemozulu yonke;
- Isicelo&imeko
-
I-Tetra 800 yokuphinda Izicelo
Ukwandisa ukugutyungelwa komqondiso wophawu lokuzalisa indawo eyimfama apho umqondiso ubuthathaka
okanye ayifumaneki.
Ngaphandle: Izikhululo zeenqwelomoya, iMimandla yoKhenketho, iiKhosi zeGalufa, iitonela, iifektri, iZithili zeMigodi, iiLali njl.
Ngaphakathi: Iihotele, amaZiko eMiboniso, amagumbi angaphantsi, iivenkile
Iivenkile ezinkulu, iiOfisi, iiNdawo zokuPakisha njl.
Isebenza ikakhulu kwimeko enjalo:
Umntu ophindayo unokufumana indawo yofakelo enokufumana isignali ecocekileyo ye-BTS kwinqanaba elinamandla ngokwaneleyo njengoko iNqanaba le-Rx kwindawo yokuphindaphinda kufuneka ibe ngaphezu kwe- -70dBm;
Kwaye inokuhlangabezana nemfuneko yokuzahlula kwe-antenna ukunqanda ukuzibamba.
